Abstract
Understanding the impact of inventive solutions on consumers’ value perception is essential to develop successful products. This applies particularly to sustainable solutions, which need to penetrate the market to pursue environmental objectives. This paper explores the value perception of three categories of TRIZ-oriented sustainable solutions, namely designs that have undergone dynamization, change of the physical state or the field exploited. Through an experimental study with 43 participants, supported by a specific questionnaire and biometric measures (eye tracking, skin conductance), self-assessments and unconscious behavioral aspects were gathered while a series of 18 product pictures was shown. Out of them, 9 products implement one of the above TRIZ-oriented principles and 9 constitute same-category products with a higher environmental impact. The results show that the different categories of TRIZ solutions give rise to diverse nuances of value perception. This outcome triggers further considerations concerning the ease of interpreting design modifications steered by TRIZ concepts and heuristics.
