Solution Overview

Problem

Existing protectors struggle to maintain an appropriate positional relationship between wiring members, particularly those with the protector main body, and the existing protector fails to keep the wiring members in a fixed position.

Innovation Solution

A protector with a partition wall that divides the accommodation space into two sections, using a curved root portion to partition the partition the accommodation space into a partition wall, and a curved root portion to solve the positional relationship between the partition the bottom and the side wall portions, and a curved partition wall, and a partition wall that partitions the space into two sections, with a curved root portion to hold and accommodate wiring members at appropriate positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a plurality of wiring members is inserted into a protector main body, then the wiring members can be held with the protector main body, but it is difficult to keep a positional relationship between the wiring members

Engineering Contradiction:
Improveholding capabilityVSAvoidpositional relationship
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The protector main body is divided into multiple accommodation spaces by partition walls, with each partition wall creating distinct upper and lower spaces. This segmentation allows wiring members to be held in specific positions within each accommodation space, maintaining their positional relationships while being accommodated in the protector.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Partition walls act as intermediary structures between the protector main body and the wiring members. These partition walls create physical barriers that define and maintain the positional relationships of wiring members, serving as mediators that enable precise positioning while providing overall holding capability.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Strength

If the partition wall has a root portion formed in a curved shape, then the strength and stability of the partition wall are improved, but the manufacturing complexity increases

Engineering Contradiction:
Improvepartition wall strengthVSAvoidmanufacturing simplicity
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The root portion of the partition wall is formed with a curved shape instead of a straight or angular configuration. This curvature distributes stress more effectively throughout the partition wall structure, enhancing its strength and stability while providing a more gradual transition between the partition wall and the bottom wall portion.

Inventive Principle:
Principle #14Spheroidality (Curvature)

AI summary

A protector includes a bottom wall portion, a pair of side wall portions, an accommodation space portion, and a partition wall. The bottom wall portion extends along a height direction in a state of being fixed to a part to be fixed. The pair of side wall portions are provided on both sides with the bottom wall portion interposed therebetween with respect to the height direction and formed to protrude along a depth direction. The accommodation space portion is defined and formed by the bottom wall portion and the pair of side wall portions, into which a plurality of wiring members is inserted. The partition wall is formed to protrude from the bottom wall portion along the depth direction and partitions the accommodation space portion into a first accommodation space portion and a second accommodation space portion, and has a root portion formed in a curved shape.
