5.1 Introduction
This section of the folio will attempt to critically analyse the design process, and the solution it produced.
5.2 Bending jig
The bending jig built for use in the construction of the support system exceeded performance expectations. Careful fitting of the central bar allowed for a good degree of material control during function testing, and prevented surface marring on test pieces and the support system components.

Overall, the constraint satisfaction chart shows a very high degree of adherence to the design constraints.
5.2.2 Summary of positive and negative features
In summation, several positive features can be noted -
In summation, several positive features can be noted -
- The swept back design is reminiscent of the Art Deco period, creating an interesting conversation point
- The external surfaces of the machined parts have an excellent finish
- The filed and brushed finish on the frame created a smooth base for the finishing product, permitting a good quality of finish
- The quality of the weld beads could be improved
- The quality of the surface finish inside the candle cup is very poor
5.3.3 Suggested future modifications
- Lay a thicker weld bead to allow for grinding and finish filing
- The addition of a secondary support leg/legs may aid in stability
5.4 Process
5.4.1 Review of process
Evaluation of the design process demonstrates that it provided quality guidance throughout the development of the tea light candle support system.

5.4.2 Summary of positive and negative features
Several positive points were noted -
Several positive points were noted -
- The research phase proved to be an invaluable aid in determining key design features
- The creation of a clear time plan aided in pacing operations in the manufacturing facility
- The narrow range of design ideas may have impeded the creation of a more effective solution
- It became possible to get 'bogged down' in certain areas
5.4.3 Suggested future modifications
- Approach the design process with a more open mind to the types of solutions that can be generated
- Adopt more streamlined tactics when undertaking difficult phases of the documentation
5.5 Conclusion
In finishing the evaluation phase, it is evident that the design process and solution were relatively successful. Although the solution does not always perform as intended, it nonetheless serves as an excellent base for refinement in future iterations.
