Busbar Frame Opening for Visual Inspection of Substrate Penetration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The state of penetration of through members into substrates in energy storage apparatuses is difficult to grasp, leading to potential attachment failures and defects due to the limited visibility of the through members' position relative to the substrate.
Innovation Solution
Incorporating a lateral member, such as a busbar frame, with openings that allow visual recognition of the through member's penetration state into the substrate, ensuring that critical junctions and attachments can be easily inspected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a lateral member (busbar frame) is disposed lateral to the substrate to cover the side surface, then the structural integrity and organization of the energy storage apparatus is improved, but the visibility of the through member's penetration state into the substrate deteriorates
Solution Approach 1:
The lateral member is segmented by forming an opening in its wall, dividing the wall into portions that allow visual access to the through member's penetration state while maintaining the overall structural integrity of the busbar frame
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 compromising the protective and structural functions of the lateral member
2Reliability
If the through member penetrates the substrate to connect components, then the electrical connection and structural stability are improved, but the ability to visually inspect the penetration state deteriorates due to the substrate blocking the view
Solution Approach 1:
The lateral member's wall is segmented by creating an opening, allowing visual inspection of the through member's penetration state into the substrate while maintaining the overall structural integrity
Solution Approach 2:
The opening provides a new visual dimension or pathway through the lateral member, enabling observation of the through member's penetration state from the side without compromising the front-to-back attachment reliability

AI summary
An energy storage apparatus (10) includes: an energy storage device (200); a substrate (500) in which a through hole (514) penetrating a main surface (510a) is formed; a through member (busbar (440)) that penetrates the through hole (514); and a lateral member (busbar frame (300)) disposed lateral to the substrate (500) and covering a side surface (510b) of the substrate (500). The lateral member includes an opening (321) through which at least one of two portions of the through member, the two portions sandwiching the through hole (514), is visually recognizable from the outside.
