Battery Connector Probe Alignment With Retractable Detection Pin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connector inspection devices often fail to couple correctly to connectors, leading to damage or improper inspection due to misalignment, and lack protection for detection members during coupling.
Innovation Solution
A connector inspection device with movable body portions that adjust coupling position and direction, featuring a detection member that protrudes only when correctly aligned with the connector, protected by elastic compression members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connector inspection device is inserted and coupled to the connector, then inspection of electrical signal transmission can be performed, but misalignment may occur causing damage to the probe pin or improper inspection
Solution Approach 1:
The probe pin is designed to be movable relative to the housing, allowing it to dynamically adjust its position during coupling. The elastic element enables the probe pin to flex and adapt to misalignment, transforming a static rigid structure into a dynamic adaptive one that can accommodate positioning variations while maintaining reliable electrical contact
Solution Approach 2:
The elastic element positioned between the probe pin and housing provides beforehand cushioning against misalignment forces. This pre-positioned elastic component absorbs shock and compensates for positioning errors before they can cause damage to the probe pin or improper inspection, ensuring reliable coupling even when alignment is not perfect
2Ease of operation
If the detection member is exposed during coupling, then electrical connection can be established, but the detection member is vulnerable to damage from external factors
Solution Approach 1:
The detection member transitions from a protected retracted state to an exposed functional state dynamically during the coupling process. The elastic element enables this dynamic transformation, allowing the detection member to remain protected by the housing during storage and transport, then extend when needed for coupling and inspection
Solution Approach 2:
The housing structure provides preliminary protection against harmful external factors by enclosing the detection member before coupling occurs. This pre-protective structure prevents damage during handling and storage, while still allowing the detection member to be exposed when properly coupled to perform its inspection function
