Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connector uses a fixed integrated structure with soldered terminals, then the structural strength and electrical connection reliability are improved, but the maintenance complexity and labor cost increase significantly when damage occurs
Solution Approach 1:
The connector is divided into separable modules: a first connector portion with first terminals and a second connector portion with second terminals. These portions can be detached from each other, allowing the damaged portion to be replaced independently without affecting the other portion, thus reducing maintenance complexity while maintaining connection reliability during normal operation.
Solution Approach 2:
The connector transitions from a static fixed structure to a dynamic reconfigurable structure. The first and second connector portions can be connected or disconnected based on operational needs or damage conditions, enabling flexible maintenance and replacement without destructive disassembly.
2Stability of the object's composition
If the connector uses a fixed integrated structure, then the structural stability is improved, but the time and labor cost for replacement increase
Solution Approach 1:
By segmenting the connector into replaceable portions, the stable connected state is maintained during normal use, while the damaged segment can be quickly swapped out without replacing the entire connector, significantly reducing replacement time and labor cost.
Solution Approach 2:
The damaged connector portion can be discarded and replaced with a new one, while the undamaged portion is recovered and reused. This approach reduces overall replacement time and material cost compared to replacing the entire fixed integrated connector.
3Ease of repair
If the connector uses a detachable design, then the ease of maintenance and replacement is improved, but the contact resistance may increase
Solution Approach 1:
An elastic terminal acts as an intermediary between the first and second connector portions. This elastic terminal provides reliable electrical contact through elastic force, ensuring low contact resistance while allowing the connector portions to be detachably connected for easy maintenance.
Solution Approach 2:
The elastic terminal utilizes elastic deformation (curved/flexible structure) to maintain continuous contact pressure, ensuring stable electrical connection with low contact resistance while enabling detachable connectivity for maintenance purposes.
