Tall slots design concept. Trolley dimensions based on calculations based on glass dimensions as well as user's physical proportions.
Side-bar design sketch Disclosure: Design conceptualised by my project mentor at the company. Rotatable side-bars Side-bars with rubber bulbs at ends support glass at height Side bars can be individually removed for glass picking Side-bars axially movable if required by change of glass shape Rubber supporters absorb glass vibrations during movement
Initial prototype Shows how a glass is held in place between 4 side-bars having cushioning at their ends, to take care of variations in shape of different glasses as well as to absorb vibrations of the glass as the trolley moves.

Glass Sequencing Trolley

This project was a part of a process improvement project in the company.

An industrial trolley was to be designed to transport windshield- and hatch-glasses to the assembly line.

Two designs were considered- the tall slots design (conceptualised by the author) and the side-bar design (conceptualised by the company mentor)

Based on the decision by the project mentor, the author started work on prototyping the side-bar design. The initial prototype shown in the pictures was completely fabricated in-house and even the material was sourced from within the company premises, based on guidance by the mentor.

This initial prototype was tested in realtime in the exact conditions the actual trolley would be used. Subsequently, the required changes were incorporated in the subsequent prototype made by the trolley supplier.
