Asymmetrical Multipole Plug-Receptacle for Secure Mini Connector Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors, such as micro and mini jack connectors, require more robust and secure solutions that are compact in size to fit into small devices while ensuring proper orientation and durability, especially in applications like hearing aids and audio equipment where space and reliability are critical.
Innovation Solution
A miniaturized multipole plug and receptacle system with an asymmetrical design, featuring a tapered front end, side recess section, and a reinforcement layer, which includes a non-conducting plug housing with upper and lower conducting poles, and a receptacle with spring-loaded arms, ensuring secure engagement and preventing incorrect orientation through asymmetrical peripheries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the size of electrical connectors is reduced to fit into small devices, then space utilization is improved, but robustness and reliability deteriorate
Solution Approach 1:
The patent applies asymmetry by creating an asymmetrical periphery on the plug housing front section, where the top and bottom curvatures differ. This asymmetrical design prevents incorrect insertion orientation and enhances connection reliability, while the overall miniaturized dimensions satisfy space constraints in small devices like hearing aids.
2Volume of moving object
If the connector size is reduced, then space requirements are improved, but manufacturing precision and assembly control worsen
Solution Approach 1:
The patent applies preliminary action through the funnel-shaped front end opening that guides the plug plate into correct position during assembly before final connection. This pre-positioning mechanism compensates for the reduced size by providing built-in alignment features that maintain assembly precision without requiring higher manufacturing tolerances.
Solution Approach 2:
The asymmetrical periphery design provides inherent orientation control during assembly, ensuring the plug connects in the correct orientation. This geometric constraint simplifies assembly control by eliminating the need for complex alignment mechanisms, thereby maintaining manufacturing precision despite miniaturization.
3Stability of the object's composition
If the securing function is provided in conducting parts, then connection stability is improved, but durability and assembly cycles deteriorate
Solution Approach 1:
The patent applies segmentation by separating the securing function from the conducting parts. The plug housing front section with its asymmetrical periphery provides the securing and orientation function, while the conducting poles and arms remain dedicated to electrical connection. This functional separation allows the conducting parts to withstand repeated assembly cycles without degradation, improving both durability and assembly cycle longevity.
