Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing connection structure of a vehicle battery terminal and battery cable is inefficient due to interference between fastening tools and surrounding components, deteriorating workability.
Innovation Solution
A battery connection apparatus featuring a tubular battery terminal connection part with male threads and a corresponding female-threaded fixing member, along with a rotation limiting mechanism, to securely connect the battery terminal and cable without interference, using a simplified and stable connection design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a tightening bolt and nut are fastened perpendicular to the battery terminal protruding direction, then the battery terminal connection part can be fixed securely, but tool interference with surrounding components occurs and workability deteriorates
Solution Approach 1:
The patent inverts the traditional fastening approach by replacing the bolt-nut perpendicular fastening system with a split ring and clip mechanism that fastens parallel to the battery terminal axis. This inversion eliminates tool interference with surrounding components while maintaining secure fixation, directly resolving the contradiction between reliability and ease of operation
Solution Approach 2:
The patent segments the connection structure into a split ring (divided into two or more sections) and a separate clip mechanism. This segmentation allows the connection part to be installed by simply fitting it around the battery terminal and then securing it with the clip, eliminating the need for complex perpendicular fastening operations and improving workability
2Reliability
If a traditional bolt and nut fastening system is used, then the connection can be secured, but the connection structure becomes complex and time-consuming to assemble
Solution Approach 1:
The connection structure is segmented into a split ring (with two or more sections) and a separate clip mechanism. This segmentation simplifies the overall structure by eliminating the need for bolts, nuts, and complex fastening systems, while maintaining secure connection through the clip that holds the split ring in place
Solution Approach 2:
The patent extracts and eliminates the complex bolt-nut fastening system from the connection structure, replacing it with a simpler split ring and clip mechanism. This extraction reduces device complexity while preserving the essential function of securing the battery terminal connection part reliably
3Reliability
If a traditional fastening method is used, then the connection can be made secure, but the assembly and disassembly process becomes time-consuming
Solution Approach 1:
The split ring is divided into two or more sections that can be easily separated and reassembled. This segmentation allows the battery terminal connection part to be quickly installed by fitting it around the terminal and secured with a clip, and just as quickly removed by releasing the clip and separating the split ring sections, dramatically reducing assembly and disassembly time while maintaining stable attachment
