Incorporating an electrically insulating, resilient member between the battery and haptic component to prevent shorting, while also transferring vibrations effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If no insulating member is positioned between the battery and haptic component, then the device structure is simpler, but electrical shorting occurs between the battery and haptic component
Solution Approach 1:
An electrically insulating resilient member is positioned between the battery and haptic component to prevent direct electrical contact. This intermediary component blocks electrical current flow while maintaining mechanical connection for vibration transmission, thus preventing shorting without significantly complicating the overall device structure.
Solution Approach 2:
The insulating member is implemented as a thin, flexible resilient film or shell that provides electrical insulation while maintaining device compactness. This thin-film approach minimizes the added structural complexity while effectively preventing electrical shorting between components.
2Reliability
If an electrically insulating resilient member is positioned between the battery and haptic component, then electrical shorting is prevented, but the haptic feedback transmission may be reduced
Solution Approach 1:
A thin resilient film is used as the insulating member to minimize mechanical impedance while maintaining electrical insulation. The thin profile reduces the barrier effect on vibration transmission, allowing haptic feedback to pass through effectively while still preventing electrical shorting.
Solution Approach 2:
The resilient member's material properties are optimized to balance electrical insulation and mechanical vibration transmission. By selecting materials with appropriate elasticity and density parameters, the system achieves both electrical isolation and effective haptic feedback transmission through the insulating layer.
3Ease of operation
If a resilient member is used to transfer vibrations, then haptic feedback transmission is enhanced, but the electrical insulation may be compromised
Solution Approach 1:
The insulating member is constructed from composite materials that combine electrical insulation properties with mechanical resilience. This composite structure enables the single component to simultaneously provide both electrical isolation and effective vibration transmission, resolving the conflict between these two requirements.
Solution Approach 2:
A flexible insulating film or shell is positioned between the battery and haptic component to provide both electrical isolation and mechanical vibration coupling. The flexible nature of this thin film allows it to transmit vibrations effectively while maintaining its electrical insulating barrier.
