Energy Storage Substrate Opening for Through-Member Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The state of penetration of through members, such as voltage detection lines, into the substrate in energy storage apparatuses is difficult to grasp, leading to potential attachment failures and defects.
Innovation Solution
Incorporating a lateral member that covers the side surface of the substrate and includes an opening through which portions of the through member are visually recognizable, allowing easy verification of the penetration state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lateral member is disposed lateral to the substrate to cover the side surface, then the substrate is protected and the structure is more complete, but the state of penetration of the through member into the substrate cannot be grasped
Solution Approach 1:
The lateral member is segmented with an opening that divides the covering structure, allowing visual access to the through member's penetration state while maintaining overall coverage and protection of the substrate
Solution Approach 2:
The opening in the lateral member acts as an intermediary that enables visual detection of the through member's penetration state without requiring removal or disassembly of the lateral member itself
2Reliability
If the through member penetrates the substrate completely, then the electrical connection is established, but it becomes difficult to visually confirm the penetration state from the outside
Solution Approach 1:
The opening provides a new viewing dimension through the lateral member, allowing visual confirmation of the through member's penetration state from a direction that was previously blocked by the solid lateral member structure

AI summary
An energy storage apparatus includes: an energy storage device; a substrate in which a through hole penetrating a main surface is formed; a through member that penetrates the through hole; and a lateral member disposed lateral to the substrate and covering a side surface of the substrate. The lateral member includes an opening through which at least one of two portions of the through member, the two portions sandwiching the through hole, is visually recognizable from the outside.
