Solution Overview

Problem

Existing cable connector assemblies lack an improved seizing structure that effectively bundles and protects the cable while maintaining flexibility and preventing exposure of metal wires.

Innovation Solution

A cable connector assembly featuring a metal wire wrapping the cable, a middle insulative layer cladding the metal wire, and an outer insulative layer wrapping the middle layer spirally, with a protective coating covering parts of the shielding layer to prevent separation and exposure, ensuring flexibility and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a metal wire is used to bundle the cable, then the bundling strength is improved, but the risk of metal wire exposure and safety hazards increases

Engineering Contradiction:
Improvebundling strengthVSAvoidmetal wire exposure hazard
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent applies nesting by placing the metal wire inside a protective coating layer, which is further enclosed by insulative layers. This nested structure allows the metal wire to provide bundling strength while being completely enclosed to prevent exposure, thus resolving the contradiction between strength and safety hazards.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The protective coating and insulative layers serve as intermediary elements between the metal wire and the external environment. These intermediaries protect against metal wire exposure while maintaining the bundling function, effectively mediating between the need for strength and the need to eliminate safety hazards.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If multiple insulative layers are added to protect the metal wire, then safety is improved, but the device complexity increases

Engineering Contradiction:
ImprovesafetyVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple protective functions into a multi-layer structure where the protective coating and insulative layers work together as an integrated system. This combining approach provides comprehensive safety protection while managing structural complexity through functional integration of the layers.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The protective coating and insulative layers are implemented as flexible thin-film structures that wrap around the metal wire. This approach provides effective protection against wire exposure while maintaining flexibility and avoiding excessive structural complexity, as thin films are easier to apply and integrate than rigid protective structures.

Inventive Principle:
Principle #30Flexible shells and thin films

3Stability of the object's composition

If the protective coating covers the shielding layer, then separation and exposure are prevented, but the manufacturing process becomes more complex

Engineering Contradiction:
Improvestructural stabilityVSAvoidmanufacturing ease
Core Design Contradiction:
Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The protective coating is applied to the shielding layer during the cable manufacturing process, before the cable is assembled into the final connector assembly. This preliminary action ensures structural stability is established early, preventing separation and exposure issues before they can occur during subsequent assembly steps.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The protective coating is nested within the overall layer structure, positioned between the shielding layer and the outer insulative layers. This nested arrangement provides structural stability by securing the shielding layer in place while integrating seamlessly with other components, thereby managing manufacturing complexity through systematic layer integration.

Inventive Principle:
Principle #7Nested doll (Nesting)
