Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing USB receptacle connectors require customization of the insulator to accommodate detection contacts, making the manufacturing process complex and reducing production rates due to the need for precise formation of detection arms and customized slots.
Innovation Solution
A receptacle connector design with a detection contact mounted outside the shell, featuring a resilient detection arm that deforms to contact the detection contact when a plug is inserted, eliminating the need for insulator modification and simplifying the manufacturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the detection contact is mounted inside the receptacle connector requiring insulator modification, then the detection function is integrated, but the manufacturing complexity increases and production rate decreases
Solution Approach 1:
The detection contact is relocated from the traditional insulator-mounted position to the outer shell of the receptacle connector. This spatial repositioning allows the detection contact to be accessible from the exterior while maintaining its detection functionality, thereby avoiding the need to modify the insulator structure and simplifying the manufacturing process.
2Adaptability or versatility
If the detection arm is formed on the ground contact, then the detection function is achieved, but the manufacturing precision requirement increases and production rate decreases
Solution Approach 1:
The detection function is separated from the ground contact structure. Instead of forming the detection arm on the ground contact, the patent uses a独立的 detection contact mounted on the shell and a separate detection arm that connects to the ground contact. This segmentation allows each component to be manufactured independently with standard processes, reducing the overall manufacturing precision requirements.
3Adaptability or versatility
If the insulator is customized to have receiving slots, then the detection contact can be mounted, but the production efficiency decreases
Solution Approach 1:
The detection contact mounting function is extracted from the insulator and relocated to the shell structure. The detection contact is now mounted on the outer shell rather than being integrated into the insulator, which eliminates the need for custom insulator designs and allows for standardized insulator production, thereby improving production efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables signal transmission, power supply, and detection functions without modifying the insulator, improving production efficiency and reducing manufacturing complexity by integrating the detection contact within the shell's structure.
Implementation Method 1
A resilient detection arm is formed on one of two sidewalls of the shell, which is adapted to be deformed by external force and recovered after removal of the external force

AI summary
A receptacle connector has an insulator, multiple contacts, a shell, an insulating bracket, and a detection contact. The shell covers the insulator and the contacts and has a cavity to receive the insulator and the contacts. A detection arm is formed on one of two sidewalls of the shell, which is resilient and able to be deformed by external force and recovered after removal of the external force. The insulating bracket is mounted outside of one of the sidewalls of the shell and has mounting slot defined in the insulating bracket. The detection contact is mounted in the mounting slot of the insulating bracket and is capable of contacting the detection arm. When a plug connector is inserted into the receptacle connector, the detection arm is bent to contact the detection contact for detecting the existence of the plug connector and activating signal transmission or power supply.
