A technique like 9 windows can be better understood with examples and the one below from triz journal explores mobile phone as a system and ideates to find the future system, sub-system and super-system. %PDF-1.4 %���� Local augmentation of the signal by land based stations and/or by dedicated regional satellites will further improve the resolution. It is not necessarily the longest dimension. This can be seen in SV19 and SV22, where both approach a high IFR when compared to SV26. As a problem is a description of some aspects of the world which have boundaries, and which evolve during time, it means that the traditional representations for systems could be used to specify problem solving. 0000000849 00000 n For example: SVs 1-5 and 9-12 can be bypassed by gains in: SVs 21-24, which can be bypassed by advances in: SVs 25 and 26. Mann (2007) identified Space/Time/Interface as the fifth pillar of TRIZ. 1.1. While one set indicated a condition of over-speeding, the other warned of a low speed stall; both conditions were dangerous. Here, the interest is focused on a dynamic study of the EV, its sub-components and internal workings. The System Operator is one of the main TRIZ instruments and, of course, one of the best instruments for systematization of thinking. SV24 suggests using an array of emitters and sensors to obtain three-dimensional flow patterns about the aircraft. Interface [FS + 1]: This first functional stream is limited to interfacing issues involving a limited amount of innovative effort. TRIZ est une théorie développée par G. Altshuller System that includes the system under consideration as a sub-system. 0000002864 00000 n Global positioning system technology is commonplace and continues to evolve at a fast pace. What is more probable is the partial obstruction of the circuit due to foreign object ingestion, wasp activity, etc. xref In this, the SV meets the first principle of axiomatic design. The separation of the paths of inquiry allows the modelling of multiple assumptions from the outset and provides for the macro level steering of solutions. 0000007677 00000 n EV3:Incomplete situational awareness (an information management issue). The detection of an obstruction is not as useful as the means of automatically removing such an obstruction during flight. A systemity is taken into account by using the following laws: Completeness and abundance of a system. Sustained innovation is analogous to a chain reaction. 0000000928 00000 n You may be able to follow the steps of improving and resolving the current speed sensoring system. 39 Parameters of TRIZ. More than three million patents have been used to discover these patterns in order to solve future problems based on a previous literature. While the problem was originally addressed through root cause … super-system, the system and subs ystem in order to ensure that the derived solution does not create any problem for the super-system or sub-s ystems. b�s�պnꢔ.�o.#��>�+����5(��21=���n�ȗ��r)V�L�̠�B���#��f?z�3� EV6:A possible inverted pyramid syndrome where the latest technology has been added to and built upon an essentially unchanged and limited foundation. In order to detect blockages for SV6 an air pressure pulse is used. Based on … One must note that … No external act of nature forced a deviation from the normal flight path. SV21 through SV26 are all examples of the fourth functional stream, FS + 4 where evolutionary change is considered to encompass the entire system in question. � �H3�����g�(���7�s�5��,��w湧����=�vg�`/m �i[��~�ۀ�68s��Q#96��V��t�q;Rb���,����k�� i�e"e�"8;�s�Qy���j�K��v�KO%q1bc���Dي�l)��������*I,�^;d�z�Q�$g�`wq��H�H��9��@k�+h�M�#�J=�3{ُ8CN��^h^���F'��ެ��O!�ED�b)h����p�Ө>K�:GR1Z�Z� �՜�}�~QPSN�6���'��G��ez�i����r�H���A0�` �:j� This relationship is linear throughout all conceivable flight parameters. The approach assists in setting out the initial assumptions for the innovation effort to proceed along multiple paths, serially or preferably in parallel. It will be noticed that the super-system includes the tool and the object of the … How to combine the diametrically opposed requirements of free association of ideas with algorithmic structuring is a debate that will continue for some time. The time period for the past and present can be defined by the user based on the context of the system/problem. This is a simple, passive SV to detect the presence of any obstruction or tape covering the static ports at night. Integration of TRIZ and roadmapping for innovation, strategy, and problem solving Phase 1 – TRIZ, roadmapping and proposed integrations Imoh Ilevbare1 Rob Phaal1 David Probert1 Alejandro Torres Padilla2 July 2011 1 Centre for Technology Management, University of Cambridge, UK. Service Innovation: Types The time period for the past and present can be defined by the user based on the context of the system/problem. Other issues such as developmental costs, environmental issues, government policy, international collaborations, etc. TRIZ is an “old” system(5,6), having been under development and in use for over fifty years. This SV is also based on EV3; however, it employs an entirely different approach.

This paper introduces the new approach with more than 25 conceptual solutions. TRIZ is defined as a problem-solving analysis and forecasting tool developed by Genrich … The outcome of any innovation activity is almost entirely contingent upon the following five factors: The accident descriptions given provide sufficient information to define the problem, form assumptions and decide on directions for investigation. The following two SVs propose extending the use of navigation technologies developed for defense purposes toward civil aviation. The lack of structure is construed as a handicap- something outside the comfort zone.2. For example, what if there is a change to the form of the material? A simple, spring-loaded mechanism keeps the ports covered until the force of the airflow is sufficient to move the covers. From an innovation perspective, these are SVs of a higher order. In English the name is typically rendered as "the theory of inventive problem solving", and occasionally goes by the English acronym TIPS. As long as the pitot and static ports are free of obstructions, the system works. Also, SV22 provides the possibility of measuring static pressure with a sealed, double-walled skin panel. trailer Since TRIZ has broad body of knowledge, we limited ourselves to studying how one of the TRIZ Trends of Technical Systems Evolution known in classical TRIZ as “The Law of Tran-sition to Supersystem” can be applied to systematically innovate new services. SV2: Detect magnetic substrate of special covering tape. The Law of Ideality • Any technical system throughout its lifeme, tends to become more reliable, simple, and effecve—more ideal.

SV21: Use special polymer external panels to register dynamic air pressure. Bons de réduction. The part of the job that our system performs has likely evolved over time. Any development of this system sees the development of the super-system. Obstructions, however, are caused by icing external object ingestion and blocked ports will generate erroneous data which may be difficult to detect before problems occur. In TRIZ, as in any other creativity-based discipline, there is no single control route to arrive at a solution to a given problem. This lapse had not been detected during the pre-flight inspection due to the metallic sheen and the height of the B757 above the ground. SV14: Built-in swing away covers over port. Once the aircraft is airborne, the landing gear doors close over the retracted landing gear, the UHF antenna begins its original task and the static port cover materially disappears. The only SVs superior are those originating from the fifth FS + PC (functional stream paradigm change) where evolutionary change is propagated to the super-system and is deployed from a higher, unknown, vista. When we have a system to analyse, we use 9 boxes to set the system context, define its environment (super-system) and all the details (subsystems). The aircraft stalled, dropped and broke up into three pieces approximately one kilometer from the runway. This is an essential requirement as it provides the structuring for the innovation task at the macro level. Altitudes displayed were widely different and seemingly contradictory alarms sounded randomly, often simultaneously. Reference: To this problem they applied TRIZ; functional analysis, trends and evolutionary potential analysis, super-system perspective of the machine, and evolutionary potential analysis of the business model. <<25dad9a8ca079a4691b3fb4408080152>]>> The limitation here is that only special tape with magnetic or conducting properties can be auto-detected (TRIZ standard solutions 1.1.1, 2.4.1, 4.4.1, 5.5.1). EV4:The inefficient transfer of vital information (an ergonomics issue). In TRIZ, a system is considered as a "system of systems" i.e. What is TRIZ? These are the active versions of SV1, where the static port is equipped with the means of checking the conductivity or magnetic substrate of the special covering tape. Space Resources, Time Resources, System resources, Function Resources, Information, Substances, Energy and Field … This caused the plane to slow down (almost to the point of entering a stall) when the wings stopped generating lift. Independent verification was sought from the Lima air traffic control radar, which acknowledged the plane’s position and confirmed its height at 8000 feet (ironically a value received from the aircraft’s erroneous transponder). This would provide not only position, altitude and velocity information but also the roll, pitch and yaw components of the aircraft’s altitude. Minimal coordination (ensuring desired relationships and interferences). System features: Size, shape, colour, transparency, weight, roughness, density, porosity, and so on. Tout système, au cours de son évolution, finit par être intégré à un super-système. Emergency braking during one of the aborted take-offs caused six of eight landing gear tires to burst on the runway. As TRIZ recommends, consider all resources when coming up with innovative ideas for the task in question. Systems engineering is a team effort with a structured development process from concept to production to operation that ensures a customer’s needs are met through a system’s life cycle. 2 Dux Diligens, Mexico. Position of the SV on the technology S-curve. Changing what our system does can be a powerful way to meet user needs and desired experiences. This set of SVs suggests using known scientific evidence and effects to measure airflow. It will require a substantial amount of research and development before a workable solution emerges (TRIZ hint: database of physical phenomena and effects, trends of evolution of technical systems). The left engine took on water and flamed out. 8 Lois d'évolution. Within this direction a number of SVs can be generated- all designed to reduce foreign object ingestion and allow relatively free passage to air. 0000001722 00000 n More... 3. This SV applies TRIZ principles to SV20 to reduce extraneous components by trimming and by merging desired properties within structural components. This shows the capabilities of TRIZ in a wide range of problems, from near-term, fine detail problems through to longer-term technology direction and high level business strategy issues. Weight of moving object . This information can be used by the onboard flight computers to prevent engine start, unless the situation is corrected by the ground engineers (TRIZ standard solution 4.1.1 self-regulating system, no need for measurement). was developed during the era of 1946 – 1985 in the USSR by Russian inventor and author, Genrich Altshuller and his colleagues.. TRIZ depends on studied patterns of problems and solutions. 0000004666 00000 n The internal tubing of the pitot-static circuit and location of the transducers has to be re-routed inside the front of the aircraft. Some of the most important ones are: • Evolution or life cycle of a TS. Within each path or super stream are mechanisms to drill down into each assumption in detail. They reflect the evolution of modern technical systems under the effect of physical and technical factors. �c[�⼐,+�Y�#�`��?�,}�{�9挑�w�;�����\�1�I�U�����C��.s�����x�Hh�.��딙gΘxn �]��~,0�L�y#C���w�+��>ሉ?|��*3��?%��W��V0.a�9���)��v:��A��^8МeDS���o`0��T2I�r|ل�� Then consider the external and internal interactions within the reference. The first version of ARIZ was developed in 1968 and many modifications during the next 20 years received. If safety problems continue, the team can begin to implement future solutions within the subsystem, system, and super-system to change or influence how the past, present, and future processes are utilized. ), An almost identical accident took place only seven months prior on February 6, 1996 when another Boeing 757-225 (registration TC-GEN), operated as a charter flight by Birgenair, crashed into the ocean at night soon after take-off.4. The aerofoil converts the energy of the airstream into an opening torque. endstream endobj 29 0 obj<>stream super-system, the system and subs ystem in order to ensure that the derived solution does not create any problem for the super-system or sub-s ystems. super system enables to increase flow more than 5S can provide. The Evolvement of Automobile Steering System Based on TRIZ Xinjun Zhao and Shuang Zhang School of Mechanical Engineering and Automation, Northeastern University, Shenyang city, P.R. Additionally, the visibility of multiple SVs encourages aspects of serendipity through further ideation and merging. Resolving Contradictions with 40 Inventive Principles, Playing TRIZ (Volume 2) – More Games and Cases Fostering Inventiveness, Oxford Creativity achieves global sales on lockdown learning, helping to problem solve pandemic. Les bons plans du moment. The ideal final result (IFR) is to not have a problem in the first place. But progress stops for no-one. A system SUPERSYSTEM II est un instrument d'éclairage multifonctions qui remplit des exigences variées dans la vente et la présentation, dans les musées et galeries tout comme dans l'hôtellerie et la gastronomie, dans les salles de conférences et le domaine privé. However, the case study he shows consistently here is clear. 2. An important issue in the processing of EVs is the mandatory requirement to continually vary the field of interest (or depth-of-field) from the artifact toward the super-system. endstream endobj 25 0 obj<>stream An initial observation was that each aircraft was airworthy until the moment of impact. The SV provides the direction to proceed in. In this SV, a segment of the external aluminum alloy skin of the aircraft is instrumented to provide deflection data under the dynamic air pressure. Several inventive principles might be in place, however, it is our jurisdiction and creativity to evaluate the best and feasible solution. Ceci se produit lorsque le système ne peut plus évoluer par lui-même. The second step is to consider other more simplified ways to deliver this main useful (value added) function by first looking within the system and if this fails by looking at other technological systems that can provide the same function but not having the disadvantages of the first system. The anomaly, however, occurred in the flow and processing of information. TRIZ Textbooks: CID Course for Children, 1-1W2: Topic 2: Where is this or that located? The super system augmented (SSA) approach is based on hybrid reasoning. TRIZ is a Russian acronym for the term “theory of the resolution of invention-related tasks”. These laws are therefore a projection into the future of the system. 0000001217 00000 n a "hierarchical system" consisting of supersystem, base system and the subsystems. On the exterior of the aircraft it may still have some form of airspeed sensors but internally all else is replaced until it reaches the data processors and cockpit displays. Loi précédente. Solution vectors form the in-process inventory of the innovative organization and can be in different states of completeness and readiness for commercial gain. TRIZ with its methodological tools, such as Main Parameters of Value Discovery, Trends of Engineering System Evolution, Quantum Economic Analysis, Failure Anticipation Analysis, and GEN TRIZ Benchmarking allow to significantly increase accuracy of technology due diligence. Dynamic laws. The pitot-static system is an established and reliable method of obtaining speed- and height-related information.7 The method is simple. One of the markers for a change-over is when the existing technology base is unable to cope with rapidly growing demands that are placed on it. Super System Transition Act : A system can merge with other systems or super systems. Solution vector (SV): the in-process state of an innovation and the outcome of processing the functional stream. For this reason SSA can be used alternately as an innovation add-on to systems engineering; or as a structuring and planning add-on to innovation tools such as TRIZ. The disorientation of the flight crew in the pitch black of night led to the declaration of an emergency; they elected to return to Lima. The idea of system evolution means that “something better is coming along” – something that corrects the deficiencies of the current approach, and offers greater functional performance than the previous system.
