Abstract

In the early stages of engineering design, numerous concepts may be envisioned and suggested. Considering normal time constraints, a large degree of design freedom may be a major challenge at this stage. Candidate concepts should be reviewed quickly and the final choice should be correct. In this regard, a simplified evaluation criterion based on cost, simplicity, and safety is suggested. Cost is estimated by required level of tolerance. Simplicity is represented by the number of parts, assembly steps, and fasteners. Safety is assessed by the level of potential failure. The proposed criterion is applied to an example swivel structure for a flat panel display stand.
