Solution Overview

Problem

Conventional metal clamps for fixing cables are bulky, difficult to adjust, and lack workability, leading to poor reproducibility and assembling accuracy due to multiple fixing points and complex overlapping structures.

Innovation Solution

A cable fixing member comprising a pair of bracket members with a fitting part that includes a convex and concave arc-shaped cross-sectional face, allowing rotation and easy opening and closing to securely hold cables, with an intermediate member crimped to the cable for enhanced clamping force and miniaturization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional metal clamp uses multiple fixing parts and overlapping clamp components, then the cable can be securely held, but the device becomes bulky and workability deteriorates

Engineering Contradiction:

Improvecable holding securityVSAvoidworkability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The clamp body is divided into a pair of bracket members that can open and close relative to each other, allowing the cable to be inserted and secured in a simple sequential manner rather than requiring complex overlapping components

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The fitting part with convex and concave portions enables one bracket member to nest within or alongside the other, creating a compact structure that reduces bulkiness while maintaining secure cable holding capability

Inventive Principle:

Principle #7Nested doll (Nesting)

2Reliability

If a conventional metal clamp has multiple fixing parts at both end sides, then the cable can be fixed reliably, but the longitudinal size increases

Engineering Contradiction:

Improvecable fixing reliabilityVSAvoidlongitudinal size

Core Design Contradiction:

ReliabilityVSLength of moving object

Solution Approach 1:

The pair of bracket members are merged into a single integrated unit through the fitting part connection, consolidating multiple fixing functions into one compact structure rather than requiring separate fixing parts distributed along the longitudinal direction

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If a conventional metal clamp has complex overlapping clamp components, then the cable can be held from multiple sides, but the manufacturing complexity increases

Engineering Contradiction:

Improvecable holding stabilityVSAvoidclamp structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The clamp is segmented into two functional parts (bracket members) that perform complementary holding actions, simplifying the overall structure compared to complex overlapping multi-component designs while maintaining stable cable holding

Inventive Principle:

Principle #1Segmentation

4Device complexity

If a conventional metal clamp has fixed clamp components, then the structure is simple, but adjusting the holding state becomes difficult

Engineering Contradiction:

Improveclamp structure simplicityVSAvoidholding state adjustability

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The bracket members are designed to be movable relative to each other through the fitting part mechanism, enabling dynamic adjustment of the cable holding state during installation and maintenance while keeping the base structure simple

Inventive Principle:

Principle #15Dynamics

AI summary

A cable fixing member is provided including a pair of bracket members that hold a cable therebetween and a fitting part that fits into the pair of bracket members. The fitting part includes a convex portion having an arc-shaped cross sectional face formed in one bracket member of the pair of bracket members; and a concave portion formed in the other bracket of the pair of bracket members and having an arc-shaped cross sectional face with which the convex portion is fitted, wherein the pair of bracket members are rotatably formed with the fitting part as a rotation center, so that facing surfaces of the pair of bracket members that hold the cable can be opened and closed.
