Solution Overview

Problem

Existing wiring modules for battery groups experience an increase in external size due to the routing of wires, which is undesirable for compact power storage device arrangements.

Innovation Solution

A wiring module design featuring an insulating protector with a routing portion and a wire fixing portion that protrudes orthogonally to the placement wall, utilizing a binding member to secure the wires, and a cover with a draw-out hole that acts as a support wall to prevent sharp bending, thereby minimizing the module's size and maintaining wire integrity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the tongue piece is formed protruding from the bottom plate of the wiring path in the direction along which the bottom plate extends, then the wires can be fixed to the tongue piece by wrapping a wrapping member around it, but the external size of the wiring module increases in the direction in which the wires are routed

Engineering Contradiction:
Improvewire fixing methodVSAvoidexternal size of wiring module
Core Design Contradiction:
Ease of manufactureVSVolume of moving object

Solution Approach 1:

The wire fixing portion protrudes in a direction intersecting the placement wall (orthogonal direction) rather than extending along the placement wall direction, changing the dimensional orientation of the fixing structure to suppress size increase in the wire routing direction

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

2Volume of moving object

If the wire fixing portion protrudes in a direction intersecting the placement wall, then the size increase in the arrangement direction can be suppressed, but the wires need additional support to prevent sharp bending

Engineering Contradiction:
Improvesize of insulating protectorVSAvoidwire integrity
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The cover with draw-out hole acts as an intermediary support structure that prevents sharp bending of wires when they are subjected to force, while the wire fixing portion provides orthogonal fixing to suppress size increase

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The wire fixing portion changes the fixing direction to be orthogonal to the placement wall, suppressing size increase in the arrangement direction while the cover provides lateral support for wire integrity

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

AI summary

An increase in the size of a wiring module is suppressed. A wiring module is for attachment to a power storage device group in which a plurality of power storage devices are arranged line up in a left-right direction. The wiring module includes: a plurality of voltage detection wires; and an insulating protector that includes a rear side routing portion in which the plurality of voltage detection wires are routed. The rear side routing portion includes a placement wall on which the plurality of voltage detection wires are placed, and a wire fixing portion that protrudes in a direction that intersects the placement wall, and to which the plurality of voltage detection wires are fixed using a binding member is provided in a region between left and right end portions of the insulating protector.
