Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
2Strength
If connectors are housed inside a bulky plug body, then the connection structure is more robust, but the device volume increases
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.
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.
3Ease of manufacture
If traditional connection methods are used, then the assembly process is simple, but the connection reliability under external forces is reduced
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.
