Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical fasteners such as screws and washers are used to provide secure electrical and mechanical interconnections between the actuator and the touch assembly, then the reliability of haptic feedback is improved, but the device complexity increases
Solution Approach 1:
The patent combines mechanical fastening and electrical connection functions into a single integrated structure. The actuator is mechanically and electrically secured to the touch assembly through a unified interconnection system that performs both functions simultaneously, eliminating the need for separate mechanical fasteners and electrical connectors.
Solution Approach 2:
The interconnection structure serves multiple functions: it provides mechanical support, enables electrical signal transmission, and ensures efficient force transfer from the actuator to the touch assembly. This multi-functional design reduces the number of separate components needed while improving overall system reliability.
2Reliability
If the actuator is securely connected to the touch assembly, then the haptic feedback quality is improved, but the manufacturing complexity increases
Solution Approach 1:
The actuator and touch assembly are designed with pre-configured connection interfaces that align automatically during assembly. Electrical contacts and mechanical mounting features are pre-positioned to facilitate straightforward integration, reducing assembly complexity despite the secure connection requirements.
3Productivity
If flexible pads are formed under the force sensors to allow lateral movement of the touch pad member, then the actuator efficiency is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The flexible pads are designed with specific material properties and geometric parameters that enable lateral movement while maintaining sufficient mechanical coupling. By optimizing the flexibility, thickness, and attachment area of these pads, the system achieves improved actuator efficiency without requiring extremely tight manufacturing tolerances.
