NineSigma, representing a global automobile-related manufacturer, seeks a development partner for a next generation clutch as a future alternative to hydraulic clutch.
The client is paying attention to the breakthrough of an electric clutch technology, and potentially apply such a technology to future electric vehicles (EVs) and hybrid vehicles (HVs). Substituting such a fundamental components as a clutch with a completely novel technology would be extremely challenging in automotive applications. Hence, the client wishes to explore technologies worth mid- to long-term development efforts.
Minimizing the energy loss is a common target in new clutch development, regardless of application field. Moreover, novel clutches are developed more actively for robotic and aerospace applications, since more design freedom is allowed compared to automobile applications. To seek a development partner from various area of expertise, the client has issued this open call.
Joint development, contract development, technology licensing
Phase 1: Proof of Ceoncept based on prototyping: 1-2 years
Phase 2: Technology development: 2-3 years after Phase 1
Details to be discussed

Anticipated collaboration style and requests to the client
Anticipated Project Phases or Project Plan
The client will review submitted proposals and possibly ask clarifying questions before selecting the most suitable candidate(s) for collaboration.
The client will select the best candidate(s) through evaluations. During the selection process, the client may execute non-disclosure agreement(s) (NDA) with selected respondent(s), seek further information disclosure, and discuss specific development targets or potential opportunities. The client will execute necessary agreement(s) with the selected respondent(s) and move to the project execution phase.
Specifics of any collaboration will be determined through consultation with the concerned parties.
