R&D exploration based only on familiar keywords can keep a search close to established expertise. At the other extreme, a vague hunt for inventions in unrelated fields may produce little that connects to the firm’s capabilities or business constraints. A productive starting point is to describe what an existing technology does and how it works.
Abstract the relevant characteristics
Instead of merely labeling a material “heat-resistant,” identify its mechanism, operating temperature, processing requirements, and repeated-use limits. Search for other industries that need the same function or different mechanisms that solve a structurally similar problem.
Turn findings into hypotheses
A parallel from another domain is not yet a development theme. State which conditions would need to change and how feasibility could be tested. Explicitly distinguish documented real-world examples from untested application hypotheses.
Compare before committing
Technical similarity is only one consideration. Manufacturing assets, customer relationships, intellectual property, regulation, and the team’s capacity may all matter. Keep several candidates alive and prioritize the uncertainty worth reducing first.
