The paper introduces guidelines to support designers to generate ideas for the development of surprising products. The guidelines are structured coherently with the concept of sensory incongruity and the Function-Behaviour-Structure framework to create a mismatch between previously conceived expectations and product features. The usability of the interactive presentation is checked with an experiment that involved more than 30 subjects with a background in product design (mechanical engineers and industrial designers), which demonstrated to be capable of generating ideas using the same.

Keywords: product design, idea generation, surprise, expectations, user-centred design
