Voice Transmitter-Receiver Plug with Clamping Lock
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice transmitter-receivers lack a mechanism to prevent the plug from being inadvertently pulled out of the electronic device's socket, leading to inconvenient and accidental disconnections.
Innovation Solution
A plug with a clamping portion that fits into a mounting hole on the electronic device's socket, allowing for fixed locking by rotating the plug, creating a secure electrical connection and preventing accidental disconnection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the plug is connected directly to the connecting socket without any locking structure, then the device complexity is reduced and ease of manufacture is improved, but the reliability of connection is worsened as the plug can be inadvertently pulled out
Solution Approach 1:
The plug structure is segmented into distinct functional parts: the body portion for insertion, the clamping portion with clamping finger for locking, and the signal line connection area. This segmentation allows each part to perform its specific function efficiently while keeping the overall design manageable and manufacturable.
Solution Approach 2:
The clamping finger is designed as a movable component that can be elastically deformed during insertion and then returns to its original position to engage with the mounting hole. This dynamic behavior enables automatic locking without requiring additional actuators or complex mechanisms, maintaining simplicity while achieving reliable connection.
2Reliability
If a clamping portion with clamping finger is added to the plug, then the connection stability is improved by preventing accidental disconnection, but the ease of operation is worsened due to the additional rotation action required
Solution Approach 1:
The clamping finger is designed with a curved trajectory that follows a rotational path during insertion. The curved movement guide ensures smooth engagement with the mounting hole while distributing the mechanical stress evenly, making the rotation action more natural and easier to perform than linear or angular constraints.
Solution Approach 2:
The clamping finger automatically engages with the mounting hole through elastic deformation and rotational movement during plug insertion. The system self-locks without requiring user intervention or additional locking mechanisms, and can be released by simple reverse rotation, making the operation intuitive and easy to perform.
3Ease of manufacture
If the clamping finger is made with high elastic deformation capability, then the ease of manufacture is improved by using simpler materials and processes, but the strength of the connection is worsened if the material is too flexible
Solution Approach 1:
The clamping finger's mechanical properties are optimized by controlling the elastic modulus and geometric parameters such as thickness, length, and cross-sectional shape. These parameter adjustments allow the finger to have sufficient elasticity for easy engagement while maintaining adequate clamping force for reliable connection, achieving a balance between manufacturability and connection strength.

AI summary
An improved voice transmitter-receiver, a plug of which has a clamping portion at a front end thereof, and a connecting socket is located on an electronic device. A mounting hole is located at an outer side of the connecting socket, thereby enabling the voice transmitter-receiver to use the plug to plug into the connecting socket of the electronic device and clamp into the mounting hole of the connecting socket by means of the clamping portion on the plug, thus connecting and fixedly locking the voice transmitter-receiver to the electronic device to prevent the plug of the voice transmitter-receiver from being inadvertently pulled out or coming away from the connecting socket of the electronic device.
