Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex grounding schemes are used for flexible conductive members, then grounding reliability is improved, but device complexity and cost increase
Solution Approach 1:
The grounding member is divided into a first grounding part connected to the grounding region and a second grounding part contacting the conductive member, allowing independent optimization of each segment's function and simplifying the overall grounding scheme
Solution Approach 2:
The grounding member acts as an intermediary component between the conductive member and the grounding region, providing a dedicated grounding path that isolates the grounding function from other circuit board components and reduces wiring complexity
2Adaptability or versatility
If flexible conductive members are used for movement, then adaptability is improved, but static electricity generation increases
Solution Approach 1:
The grounding member provides a controlled path for static electricity generated by the flexible conductive member during movement, converting the harmful static discharge into a safe, directed current flow to the grounding region, preventing damage to electronic devices
Solution Approach 2:
The grounding member is pre-configured to contact the conductive member before movement occurs, establishing a grounding path in advance to prevent static electricity accumulation during subsequent flexible movements
