Solution Overview

Problem

Existing audio connectors are prone to malfunction due to excessive forces applied during use, leading to connection failures in electronic devices, which results in warranty costs for manufacturers.

Innovation Solution

A connection cable and audio jack plug assembly where the conductive wires are connected mechanically and electrically through compression within the inserting member, eliminating the need for a bulky plug body and reducing exposure to external forces, allowing for a more robust and environmentally friendly assembly process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a bulky plug body is used to house connectors inside, then the connection structure is more robust, but the exposure to external forces increases and the device size increases

Engineering Contradiction:
Improveconnection structure robustnessVSAvoidexposure to external forces
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the connectors from the bulky plug body and integrates them directly into the inserting member. The conductive wires are connected to the conductive parts of the inserting member without requiring a separate plug body housing, thereby eliminating the exposure problem while maintaining connection functionality.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent merges the function of the plug body with the inserting member itself. The inserting member serves both as the connection interface and as the housing for the conductive wire connections, eliminating the need for a separate bulky plug body structure.

Inventive Principle:
Principle #5Merging (Combining)

2Strength

If connectors are housed inside a bulky plug body, then the connection structure is more robust, but the device volume increases

Engineering Contradiction:
Improveconnection structure robustnessVSAvoidplug body volume
Core Design Contradiction:
StrengthVSVolume of moving object

Solution Approach 1:

The patent removes the bulky plug body from the design and integrates all connection functions directly into the inserting member, significantly reducing the overall volume of the connecting device while maintaining connection robustness.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent combines the functions of the plug body and inserting member into a single integrated structure, eliminating redundant components and reducing the overall device volume while maintaining structural integrity.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of manufacture

If traditional connection methods are used, then the assembly process is simple, but the connection reliability under external forces is reduced

Engineering Contradiction:
Improveassembly process simplicityVSAvoidconnection reliability under external forces
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent incorporates strain relief features and flexible cable management into the design from the outset, preventing excessive forces from reaching the connectors before they can cause damage. This preliminary protective action maintains connection reliability without complicating the assembly process.

Inventive Principle:
Principle #10Preliminary action
