Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery terminals face difficulties in controlling the tightness of electrode connections, leading to potential electrode transformation, high electric resistance, and inconvenient connection processes due to fixed insertion openings and bolt locations.
Innovation Solution
A battery terminal design featuring a fixing block and inserting block with inclined surfaces and semi-circular grooves, allowing controlled opening adjustment and maximizing contact surface area, along with a fixing bolt that controls the connection from the upper portion, preventing excessive tightness and enhancing conductivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the opening of the insertion member is made larger to facilitate electrode insertion, then the ease of operation is improved, but the connection becomes loose and reliability deteriorates
Solution Approach 1:
The insertion member's opening is made variable rather than fixed. The opening can be adjusted between a first opening (larger) for facilitating electrode insertion and a second opening (smaller) for ensuring tight connection. This dynamic adjustment resolves the contradiction between ease of operation and connection reliability.
2Reliability
If the opening of the insertion member is made smaller to ensure tight connection, then the reliability is improved, but the ease of operation deteriorates as insertion becomes difficult
Solution Approach 1:
The insertion member's opening is made variable rather than fixed. The opening can be adjusted between a first opening (larger) for facilitating electrode insertion and a second opening (smaller) for ensuring tight connection. This dynamic adjustment resolves the contradiction between ease of operation and connection reliability.
3Reliability
If the electrode is connected tightly to reduce electric resistance, then the electrical conductivity is improved, but the electrode may transform and the ease of operation deteriorates
Solution Approach 1:
The insertion member's opening is adjusted to a smaller second opening during the connection phase to ensure tight connection and reduce electric resistance, improving electrical conductivity. The variable opening design allows this tight connection without permanently deforming the electrode, resolving the contradiction between electrical conductivity and ease of operation.
4Device complexity
If the bolt for controlling the opening is located at the side or lower portion to simplify structure, then the device complexity is reduced, but the ease of operation deteriorates when the bolt is at a dented portion
Solution Approach 1:
The bolt is repositioned from the side or lower portion to the upper portion of the insertion member. This positional change in the vertical dimension allows the bolt to be accessed more easily, especially when the battery is installed in dented or constrained spaces, resolving the contradiction between structural simplicity and operational ease.
