Introduction to project

1. Analysis of a design problema) Description of the design problem

The task of this project is to design and construct building and/or construction models to a 1:87 (HO) scale model for QACI City.

b) Data from market and user research The Research was focused on different scale model related sites including hobby craft

model sites. These sites mostly provided information on premade/preassembled or unassembled models such as the dimension (length, width, height), base (types of material, e.g. Mahogany) and scale of the model.

c) Detailed design brief The expected outcomes for the design product are to design building and/or

construction, which well, represents the building in real life and is proportionate to other models.

d) Marketing specifications The target market sectors are QACI, other designers, engineers, architects, and

professional hobby model makers. The target audiences are people who have interest in hobbies like scale model

making or RC trains. Design product user requires nothing because the models can be used as

accessories or toys instead of professional tools. Otherwise the product is pre assembled allowing easy access for the product user.

e) Design specifications There are no aesthetic, cost, customer or environmental requirements. The size constraints are that it has to be in the ratio of 1:87. The model does not have to move because it will be placed for visual purpose

only. The models can be made of any given materials including cardboards and

acrylics.

2. Conceptual Designa) Design ideas

To make tracks and trains including turns, intersections, lights, cabins and carriages.The tracks were to be linked with jigsaw like joints. Also the tracks had gaps between the rails to mimic the shape of the real train tracks.

b) Concept modeling of preferred design2D CAD of the tracks 2D CAD of the train

3D model prototype of train on top of a track, (missing a wheel in the middle)

3rd party feedback on modeling to assist further development When assembling the tracks, the thin 2mm bars are glued on top of the adjacent tracks so that there is no gap towards the outside and 1mm gap towards the inside of the track. When assembling the trains/carriages the smaller wheel goes on the outside and the bigger wheel towards the inside.Student Note: A 3rd party is someone who is not immediately connected to the design problem, and is not the designer (1st party) or customer (2nd party) in the design solution)

c) Justification of appropriate development idea The train is well scaled to the tracks, however, neither the train not the track

has been compared to buildings or constructions of other works, therefore its overall scale is uncertain.

3. Development of a detailed designa) Selection of materials and components for prototype

For the prototype thin cardboard was used as the material, but was planned to use acrylic for final design.

b) Manufacturing techniques for prototype construction The prototypes will be made of thin cardboards until the final design. The final

design will consist of cardboard rails, acrylic trains and carriages.c) Detailed design proposal

For final design, it is recommended to replace the square based bars which hold the wheel with a slim round bar of strong smooth materials such as acrylic or metal.

d) Detailed manufacturing plan for prototype

4. Testing and Evaluationa) Evaluation of the design solution against marketing specifications

material.Environmental requirements

Reusable if required. If made of foam, acrylic or other materials, cannot be recycled.

Size constraints Simple design. Errors in the scaling.Safety considerations Wear gloves while using

glue.none

Performance requirements and considerations

Though the wheels are not made for rolling purposes, if well guided, it can move through challenging tracks such as intersections.

The wheels are not made for rolling purposes, therefore if forced to move, it may result in breakage.

Materials requirements Most board materials are fit for use.

Weak depending on the softness of the material.

Manufacturing requirements

Access to laser printer Use of cardboard when wet from glue.

c) Improvements to the design solution

5

From the evaluation of the prototypes, the use of wheels could be improved. Because the bars holding the wheels are square based, it does not turn well. Therefore the bars could be replaced with different material.

5. Glossary of Technical Terms used in the Project

Technical term DefinitionCAD CAD is an acronym for “Computer Aided Design” and it is used to

assist a designer in the development and realization of a design concept utilizing a computer and software

Constraints Constraints in a design can be features, sizes, function or appearance etc. which are essential requirements and not usually negotiable to change.
