It has been absolutely inspirational to see the change in mood in the room now that the students are actually putting their plans into action. However, I think today many groups hit their first obstacle when they realized that the solutions might be more difficult to create than previously thought.
For example, the surrey group realized that their permanent fold out box actually caused discomfort to passengers. The team came together with the apprentice leaders and faculty to evaluate and then decide to redesign the storage space to be removable. This is only one of the several examples of how the students have actually learned the importance of a reiterative prototyping design process.
In the team meetings the groups have also began evaluating what different materials, structure, calibration requirements, and hinges the final design might require.
