Abstract
The aim of this thesis was to develop the Uniti One window design from a prototype stage to be ready for mass production. Uniti One is a lightweight, two-seated, electric vehicle of the L7e-category designed for urban transportation. In late 2017, three prototypes of this vehicle were built, and that construction was used as the start point of the development.
Vehicle regulations, material theory and manufacturing limitations were all investigated together with design intent data from Uniti’s staff, to determine design limitations. Once all limitations were recognized, new glazing concepts could emerge. Since Uniti Sweden had put down years of research into the actual shape of the canopy, this was to be kept as close to the prototype... (More)
The aim of this thesis was to develop the Uniti One window design from a prototype stage to be ready for mass production. Uniti One is a lightweight, two-seated, electric vehicle of the L7e-category designed for urban transportation. In late 2017, three prototypes of this vehicle were built, and that construction was used as the start point of the development.
Vehicle regulations, material theory and manufacturing limitations were all investigated together with design intent data from Uniti’s staff, to determine design limitations. Once all limitations were recognized, new glazing concepts could emerge. Since Uniti Sweden had put down years of research into the actual shape of the canopy, this was to be kept as close to the prototype shape as possible. The challenge was therefore to choose which regions of the glazing that should be manufactured in glass or plastic and how the split up should be defined.
The result was a new canopy designed with three glass and seven plastic windows which passed all L7e-regulations. For all windows, manufacturing techniques, alternative materials and coating suggestions are described. The construction of the glazing was made using surface modeling tools and the method is described in detail to allow Uniti to redo the work on future iterations. Further work needs to be done to optimize the construction of the Uniti One windows including supplier limitation control, aerodynamic and structural calculations and cost optimization. (Less)
