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

VSEngineering 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

Engineering Contradiction:
Improvestructural integrityVSAvoidvisibility of through member penetration state
Core Design Contradiction:
Stability of the object's compositionVSDifficulty of detecting and measuring

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

Inventive Principle:
Principle #1Segmentation

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

Inventive Principle:
Principle #24Intermediary (Mediator)

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

Engineering Contradiction:
Improveattachment reliabilityVSAvoidvisual inspection capability
Core Design Contradiction:
ReliabilityVSDifficulty of detecting and measuring

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

Inventive Principle:
Principle #1Segmentation

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

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

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.
