Electric Storage Module Cable Fixing Portion

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional electric storage modules have limited flexibility in cable layout due to cable fixing portions that allow routing only in one direction, restricting the positioning and orientation of cables.

Innovation Solution

The electric storage module features a cable fixing portion with multiple insertion holes on its outer surface, allowing cables to be fixed through these holes, which can be oriented in various directions, enhancing the flexibility of cable layout and integration with the outer package member.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single through-hole is used in the cable fixing portion, then the structure is simple, but the cable layout flexibility is limited

Engineering Contradiction:

Improvecable layout flexibilityVSAvoidcable fixing portion structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The cable fixing portion is segmented into multiple insertion holes instead of a single through-hole. Each insertion hole can independently receive and fix cables, allowing cables to be routed in different directions and positions. This segmentation directly increases cable layout flexibility while maintaining a relatively simple overall structure.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The cable fixing portion is designed with multiple insertion holes that can serve multiple functions: fixing single cables, bundling multiple cables together, routing cables in different directions, and accommodating cables of various sizes. This multi-functionality enhances adaptability without requiring separate fixing mechanisms for different cable scenarios.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Area of stationary object

If cables are routed close to bus bars, then space is saved, but magnetic interference increases

Engineering Contradiction:

Improvemodule space utilizationVSAvoidmagnetic interference

Core Design Contradiction:

Area of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The outer package member serves as an intermediary barrier between the cables and bus bars. By providing insertion holes on the outer surface of the package member, cables can be routed through this intermediate structure, maintaining a physical separation from the bus bars. This intermediary structure enables space-efficient routing while protecting against magnetic interference.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If cables are fixed on the outer surface, then accessibility is improved, but exposure to external factors increases

Engineering Contradiction:

Improvecable installation accessibilityVSAvoidexternal environmental factors

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The cable fixing portion is nested within or integrated with the outer package member structure. The insertion holes are formed in the package member itself, allowing cables to be fixed on the outer surface while the package member provides protective enclosure. This nesting arrangement enables easy cable access while maintaining protection against environmental factors.

Inventive Principle:

Principle #7Nested doll (Nesting)
