Spring Contact Battery Holder Vibration Resilience
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Measuring instruments with spring contact type battery holders are prone to contact faults due to external vibrations or shocks, leading to power disruption and data loss, especially during natural disasters.
Innovation Solution
A spring contact type battery holder design where at least two batteries are connected in parallel with their positive and negative electrodes aligned on the same straight line, ensuring that if one battery loses contact, power can be continuously supplied from the other, using conical coil springs for enhanced durability against vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If all batteries are arranged in the same direction to simplify the battery holder structure, then the device complexity is reduced, but the reliability deteriorates because all batteries may be simultaneously separated from contact during vibration or shock
Solution Approach 1:
The patent divides the battery arrangement into two groups with different orientations. Specifically, some batteries are arranged with their positive electrodes facing upward while others are arranged with positive electrodes facing downward. This segmentation ensures that during vibration or shock, not all batteries will simultaneously lose contact with the spring contacts, thereby maintaining power supply reliability while keeping the battery holder structure relatively simple.
2Reliability
If spring contacts are made more rigid to prevent contact faults, then the reliability is improved, but the ease of operation deteriorates because the spring contacts cannot accommodate battery installation and removal
Solution Approach 1:
The patent employs spring contacts with optimized elastic properties that allow them to deform during battery installation and removal, then maintain sufficient contact pressure during operation. The spring contacts are designed with appropriate stiffness to accommodate operational dynamics while ensuring reliable electrical connection. This dynamic design allows the same spring contact to serve both installation/removal operations and maintain contact stability during device operation.
