Solution Overview

Problem

The existing battery wiring modules require additional parts to hold electric wire groups for multiple battery modules and junction boxes, leading to increased size and complexity.

Innovation Solution

A battery wiring module with a resin protector that integrates a first wire holding part and a second wire holding part, where the second part can cover the first, allowing for the simultaneous accommodation of two types of electric wire groups without additional components, utilizing a hinge for efficient attachment and accommodation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate members are provided to accommodate electric wires for each battery module or junction box, then the electric wires can be held and organized, but the number of parts increases and the overall size increases

Engineering Contradiction:
Improvewire holding capabilityVSAvoidnumber of parts
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple wire holding functions into a single resin protector by providing both a first wire holding part and a second wire holding part within the same component. This allows electric wire groups from multiple battery modules or junction boxes to be accommodated in one integrated structure, reducing the total number of separate parts while maintaining reliable wire organization and protection

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If separate members are provided to accommodate electric wires for each battery module or junction box, then the electric wires can be held and organized, but the overall size increases

Engineering Contradiction:
Improvewire holding capabilityVSAvoidoverall size
Core Design Contradiction:
ReliabilityVSArea of stationary object

Solution Approach 1:

The patent merges multiple wire accommodation functions into a single resin protector structure, allowing electric wire groups from multiple battery modules or junction boxes to be held within one compact unit. This integration significantly reduces the overall space required compared to using separate wire holding members for each module

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements a nested configuration where the second wire holding part is disposed to cover the first wire holding part. This nesting arrangement allows multiple wire groups to be accommodated in a compact, space-efficient manner within the single resin protector, minimizing the overall footprint while maintaining organized wire separation

Inventive Principle:
Principle #7Nested doll (Nesting)

3Adaptability or versatility

If multiple separate wire holding members are used, then different electric wire groups can be accommodated, but the assembly and installation process becomes more complex

Engineering Contradiction:
Improvewire group accommodationVSAvoidassembly process
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent integrates multiple wire holding functions into a single resin protector with both first and second wire holding parts, allowing different electric wire groups to be accommodated simultaneously. This unified structure simplifies the assembly process by reducing the number of separate components that need to be installed and connected

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A battery wiring module 20 configured to be attached to a single cell group 10, which is a plurality of single cells 11 in which positive and negative electrode terminals 12 are lined up, includes: a connecting member 21 that connects adjacent ones of the electrode terminals 12; and a resin protector 30 that holds the connecting member 21. The resin protector 30 is provided with a first wire holding part 40 and a second wire holding part 44 that are respectively capable of holding two types of electric wire groups W1 and W2. The second wire holding part 44 is arrangeable to cover the first wire holding part 40.
