     Design Project – Fischer Technik Mechanisms Kit

1.        Introduction
1.1       We perceive an opportunity exists for the development of learning toys for young children.
          We are looking for new ideas based around the use of standard Fischer Technik components.
1.2       The idea is to produce a series of small kits that can allow children the opportunity to play
          and learn about basic engineering mechanisms. The kit must offer a complete solution for a
          toy based on a particular type of mechanism, or mechanisms.
1.3       Increasingly the consumer’s first introduction to new products is through the media such as
          mail-order catalogues, posters and point-of-sale material. In fact the range of choice can be
          bewildering, especially when the product may have special technical features which may not
          be immediately apparent. The appeal that some products have is dependant on the way that
          they are presented and how some of the key features are shown or explained. The kit must
          be presented in such a manner that it conveys both the essence of play to a child and
          educational opportunity to a purchasing adult.
2.        Brief
2.1       Develop a proposal for a learning toy based on the Fischer Technik range of products and
          components.
2.2       The toy should demonstrate the operation of some type of mechanism, or mechanisms, but
          in an intriguing and fun way to a young child. The toy can be static or mobile but must be
          ‘powered’ by the child.
2.3       The toy needs to be relatively small and economical in both parts and cost. It is expected
          that non standard components and features will be required to complete the toy. These non
          standard parts are to be prototyped and need not necessarily be of a final finish quality.
2.4       The toy must be supplied as a kit and the child must be able to understand the instructions
          and assemble it themselves. The kit should provide the opportunity to assemble variations
          of the toy so that the child can see the effect of changing components, positions of
          components, etc in their play.
2.5       Your team needs to consider the total design of the product. This should include the standard
          components used; special mouldings; instructions; packaging and relative costs. The needs
          of the users (pupils, parents) should be identified to support the learning opportunities that
          your proposal will meet.
2.6       We expect to see CAD assemblies, working models and a demonstration of what your
          finished concept can achieve. This should be supported with drawings, visuals and
          illustrations of the concept with a clear explanation of what it does and how it works.

3.       Product Educational Requirements
3.1     Mechanisms are used to convert between one type of motion and another. Any machine can
        be looked on as a group of interconnected mechanisms which convert one type of motion to
        a variety of other motions.
3.2     These changes may be to convert rotary motion to straight line motion or to convert
        reciprocal (back and forth) motion to intermittent motion. They may also transform a fixed
        type of motion, for example by magnifying a linear motion or by slowing down a rotary
        motion. Different mechanisms can also be combined to produce compound mechanisms as
        commonly seen on many machines.
3.3     The same basic mechanism can be used to show how the variation in set up of the
        mechanism can result in very different, but predictable, changes in motion.
3.4     Your design should aid a child to understand the mechanism used, and through play,
        discover how variations of set-up effect the motion.
4.       Prototype Parts
4.1     Each kit is to primarily include standard items from the current Fischer Technik catalogue.
        Additional prototype parts will be required to complete the kits. These must include both
        technical and aesthetic items:
        Technical Item(s) – These are possible new Technik parts that could be used in a variety of
        Technik models and must fit the standard parts (e.g. a type of cam). Each team is restricted to a
        total base area of 100x100mm on the FDM machine (if using this process)
        Aesthetic Item(s) – These are items probably specific to the actual kit being designed and are to
        be used to make the kit more closely represent the idea of the toy (e.g. a shell, body or skin to
        make the kit more closely resemble reality).
        The prototype parts are not production parts. They do not necessarily have to match exactly the
        production part you envisage for the kit. For example it is perfectly acceptable to manufacture
        a cardboard body as a prototype to represent a formed plastic body that would be used in
        production. It is necessary, however, to indicate how the production part will differ from the
        prototype part in the design report.
5.       Construction
5.1     The use glue or oil on the plastic components is NOT allowed. Prototyped aesthetic parts
        may be glued to each other but must only be fixed to any ‘standard’ Technik part by the
        standard proprietary connectors.
6.       Aims
6.1     The company marketing this concept wants to be sure that their target market(s) is aware of the
        full potential of the product, its features, function and intended uses and learning opportunities.
6.2     Themes that the company is interested in are:-
        Play
        Experimentation
        Invention
        Extension with other kits they manufacture
        History of technology
6.3     You should consider other uses and situations that could make use of the key features of
        your design concepts.

7.       Objectives:
            Defining the brief
            Designing with technological awareness
            Designing for the market
            Designing the complete product package
            Manufacturing awareness
            Use of CAD and Rapid prototyping
            Visual communication of 3D concepts
            Time planning
            Team working
            Presentation of ideas
8.       Deliverables:
         Continuous evidence of work done will be required at several stages of the design project
         (see section 12). The main final deliverables are as follows:
8.1     Portfolio
         Supporting portfolio of competitive products, influencing ideas, sketch selection, design
         details, fixings, fastenings, articulation, sketch models, design parameters, technological
         dynamics, texture, patterns, materials, manufacturing process, planning sheets, versatility,
         style, ergonomics, performance, graphics, presentation ideas etc..
8.2     Design Report:
        Mechanism(s) chosen and arguments for choice
        Brief Product Design Specification indicating kit performance required only
        Brief details of concepts generated and evaluation process used to determine final choice made
        This can be done for different stages and levels of detail for the product
        General description of the kit and design points
        Bill of Materials
        Design analysis and calculations where appropriate
        Detail drawing of prototyped components (SolidWorks Part)
        General Arrangement drawing of completed kit (SolidWorks Assembly)
        Brief minutes of all group design meetings held
        Discussion of complete process of design and the way your team would improve the process.
8.3     Product Model
         Working model of the product, complete with prototyped parts, packaging and instructions.
         A model, by definition, is a simplification of the actual product. It is required to represent
         the product in all major aspects but does not have to be of final product quality or detail.
9.       Assessment Overview:
         This Team project requires good communication between team members outside of the
         lecture sessions. You will need to be organised and objective in your approach. Most
         importantly you will need to be innovative with your ideas. Looking at existing product will
         only show what other designers have done. Looking at products for their interesting features
         i.e. surface finish, construction, materials, assembly techniques etc., should be more
