© 2020 IEEE.No company can survive in today's market environment without being innovative. Every innovation starts with an innovation idea (referred to as 'idea' within this paper). Creativity techniques like Design Thinking enable the generation of a variety of ideas. However, selecting the right ideas for development and market launch imposes a challenge to companies which is yet unsolved. Recent studies show that only one out of 3,000 initially selected ideas leads to a successful product innovation. This poor success rate is due to an exclusive focus of today's evaluation processes on the idea's potential economic return. The functional and technological realization of this potential, however, is mostly neglected. Therefore, this paper aims at developing a model for assessing the realizability of innovation ideas for technical systems. For this purpose, the authors suggest applying the concept of logic determination to the evaluation of ideas.
