Solution Overview

Problem

Existing cable management systems for mobile devices struggle with cable twisting and breaking, especially when extended or retracted, and often require complex structures that complicate electrical connections and are not adaptable to varying table thicknesses.

Innovation Solution

A cable retraction unit assembly with a guide housing and withdrawal unit mounted on a table, featuring a rotatable guide unit with a locking mechanism and ball bearings to reduce friction, and adjustable coupling with a locking bolt to accommodate different table thicknesses, allowing smooth cable extension and retraction without twisting or breaking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Length of moving object

If the cable is extended for convenient product examination, then the cable length is increased, but the cable may twist or break

Engineering Contradiction:
Improvecable lengthVSAvoidcable durability
Core Design Contradiction:
Length of moving objectVSReliability

Solution Approach 1:

The guide unit is designed to be rotatable within the guide housing, allowing the cable to rotate freely as it is extended or retracted. This dynamic adjustment prevents the cable from twisting or breaking by accommodating changes in cable orientation and tension throughout its range of motion.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If a fixed cable management structure is used, then the structure is simple, but it cannot adapt to varying table thicknesses

Engineering Contradiction:
Improvestructure simplicityVSAvoidadaptability to table thickness
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The cable management system is divided into separate components: a guide housing that can be mounted at different positions, a rotatable guide unit, and a withdrawal unit. This segmentation allows each component to be independently positioned and adjusted, enabling the system to adapt to various table thicknesses while maintaining overall structural simplicity.

Inventive Principle:
Principle #1Segmentation

3Stability of the object's composition

If the guide unit is fixed in position, then the structure is stable, but the cable cannot rotate freely causing twisting

Engineering Contradiction:
Improveguide unit stabilityVSAvoidcable rotation freedom
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The guide unit is designed to be rotatable within the guide housing, allowing the cable to rotate freely as it is extended or retracted. This dynamic adjustment prevents the cable from twisting or breaking by accommodating changes in cable orientation and tension throughout its range of motion.

Inventive Principle:
Principle #15Dynamics
