New products are often thought of as functional, and artistic projects for the sake of creation but the reality is functionality thinking limits. The reality is that variety, a significant difference is seen between nonfunctional ( desires ) and hard functional requirements. Limiting desires and room to move within the artistic space for design could not have been better identified by Emily Worinkeng, Shraddha Joshi & Joshua D. Summers
The reality of the design world, architecture and often product definition and entrepreneurship is that nonfunctional requirements, typically captured as constraints on the design space ( user desires and the designers own interpretation of what is needed ) often serve ( as a measured quantity ) to not only enablers ideation but novelty and variety and as show in a few previous discussions here and with clients, clearly leads to an understanding of the mechanisms of disruptive design coming together to create successful products.
