Battery Box Elastic Connector for Automatic Cover Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery boxes often experience breakage of the rigid structure connecting the end cover and housing during opening and closing, leading to operational issues.
Innovation Solution
The battery box employs an elastic connector comprising a spring, rotation shaft, rivet, steel piece, and magnets to control the opening and closing of the end cover, providing a secure and automatic closure mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid structure (hinge or buckle) is used to connect the end cover and housing, then the connection strength is improved, but the structure tends to break off during opening and closing operations
Solution Approach 1:
The patent replaces the rigid connection structure with a dynamic elastic connector system comprising a spring and rotation shaft. The spring provides flexible elastic force that adapts to opening and closing operations, while the rotation shaft enables rotational movement. This dynamic structure eliminates the breakage issue of rigid connections while maintaining connection strength throughout operational cycles.
Solution Approach 2:
The patent changes the mechanical parameters of the connection system by introducing elastic elements. The spring's elastic coefficient and the rotation shaft's rotational characteristics create a connection mechanism that transitions from rigid to flexible, allowing the structure to withstand repeated opening and closing operations without breaking.
2Ease of operation
If an elastic connector is used to control opening and closing, then the ease of operation is improved, but additional components (spring, rotation shaft, rivet) are required
Solution Approach 1:
The patent merges multiple functions into the elastic connector assembly. The spring provides both the elastic force for opening and the closing force, while the rotation shaft handles both rotational movement and structural connection. The rivet simultaneously secures the spring to the rotation shaft and provides structural anchoring. This functional merging reduces overall system complexity despite adding elastic components.
Solution Approach 2:
The elastic connector components serve multiple functions: the spring provides elastic force storage and release, the rotation shaft enables movement and structural support, and the rivet provides both fastening and positioning. This multi-functionality reduces the need for separate dedicated components, balancing ease of operation with acceptable device complexity.
3Force
If magnets are added to strengthen closing force, then the closure security is improved, but the device complexity increases
Solution Approach 1:
The patent replaces part of the mechanical closing force system with a magnetic field system. The magnets provide a non-contact closing force that supplements the spring's elastic force. This substitution reduces mechanical wear and provides consistent closing force without requiring additional mechanical levers or springs, thereby increasing closing force while limiting complexity growth.
