Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing stacked power storage devices face challenges in securing space for component connections due to the thin plate shape of power storage modules and conductive boards, leading to complex positioning issues and increased contact resistance during voltage detection and temperature measurement.
Innovation Solution
A conductive module with a plate-shaped housing that includes a terminal accommodating recess for the voltage detection terminal and a temperature measurer accommodating recess for the thermistor, along with a heat-conductive filler, allows for easy alignment and reduced contact resistance by exposing parts of the conductive board and using a cover for protection, eliminating the need for additional connection components like bolts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the detection terminal is inserted into the insertion hole of the conductive board from the lateral side, then the connection between the conductive board and detection terminal can be established, but the positioning becomes complicated and workability deteriorates
Solution Approach 1:
Instead of inserting the detection terminal laterally into the conductive board as in the related art, the invention inverts the connection approach by having the conductive board inserted into the housing from the upper side, with the detection terminal already positioned within the housing. This reversal of the insertion direction simplifies positioning and significantly improves workability while maintaining reliable electrical connection.
2Volume of moving object
If the power storage modules and conductive boards are made thin plate shape, then the device compactness is improved, but the space for installing connection components is insufficient
Solution Approach 1:
The invention merges the detection terminal and temperature measurer into a single integrated housing structure. By combining these components and their mounting structures into one unified housing, the design eliminates the need for separate connection components and complex positioning mechanisms, thereby maintaining compactness while reducing overall structural complexity.
Solution Approach 2:
The housing serves multiple functions simultaneously: it accommodates the detection terminal, houses the temperature measurer, provides structural support, and facilitates the insertion connection. This multi-functionality reduces the need for additional dedicated components, simplifying the overall structure while maintaining the thin plate design.
3Strength
If the detection terminal is connected using bolts or other connection components, then the connection strength is improved, but the space requirement increases and workability deteriorates
Solution Approach 1:
The invention extracts and eliminates the need for bolts and other separate connection components from the assembly process. The conductive board is designed with insertion portions that directly engage with the housing, creating a secure electrical and mechanical connection without requiring additional fastening elements, thereby simplifying the connection process while maintaining sufficient connection strength.
