Stacked Abutment Members With Positioning Features
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electric storage apparatuses face challenges in reducing size while maintaining strength, leading to increased complexity and reduced assembly efficiency due to the need for thicker end parts or multiple stacked members, which complicates the positioning and assembly process.
Innovation Solution
The electric storage apparatus employs an abutment configuration with at least three stacked members, each with positioning parts having recesses and projections, allowing for precise alignment and integration through corresponding positioning parts, facilitating assembly by forming a single, integrated unit with reduced size and maintaining strength through metal plating and insulating members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the plate thickness of end parts is increased to ensure strength, then the strength of end parts is improved, but the size of the electric storage apparatus increases
Solution Approach 1:
The end part is segmented into multiple thin members (first through fourth members) stacked together, each with specific functions such as insulation, reinforcement, and electrical connection. This segmentation allows the end part to achieve required strength through the combined effect of multiple thin layers rather than requiring a single thick plate, thereby reducing the overall apparatus size while maintaining structural integrity.
2Volume of moving object
If multiple thin members are stacked to form end parts to reduce size, then the size of the electric storage apparatus is reduced, but the number of parts increases and assembly operation becomes complicated
Solution Approach 1:
Multiple thin members (insulating members and reinforcing members) are merged into a single integrated end part structure through stacking and positioning. The members are designed with complementary features such as positioning projections and recesses that enable automatic alignment when stacked, reducing assembly complexity despite the increased number of components. The insulating and reinforcing functions are combined in a compact stacked arrangement.
3Volume of moving object
If three or more members are stacked to form end parts, then the size is reduced and strength is maintained, but the positioning operation becomes significantly more complicated
Solution Approach 1:
Positioning projections and recesses are pre-formed on the members during manufacturing, enabling automatic positioning when the members are stacked during assembly. This preliminary preparation of positioning features eliminates the need for complex real-time alignment operations during assembly, significantly reducing assembly time and complexity while allowing multiple members to be stacked efficiently.
