Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual plugging and unplugging of pin headers is used, then the connection is secure and reliable, but the installation process is time-consuming and laborious
Solution Approach 1:
The patent applies the dynamics principle by transforming the static manual plugging operation into a dynamic automated process. The rotating shaft with cam structure converts rotational motion into linear pushing motion, automatically guiding the pin header into the female header and securing the connection. This dynamic mechanism eliminates manual intervention while maintaining connection reliability, thereby reducing installation time and labor requirements.
2Reliability
If tight plugging between pin header and female header is implemented, then the electrical connection is secure, but the manual operation becomes more difficult and time-consuming
Solution Approach 1:
The patent implements the self-service principle through the self-aligning cam mechanism. As the rotating shaft turns, the cam profile automatically guides the pin header into proper alignment with the female header and applies the necessary insertion force. The mechanism self-regulates the plugging process, ensuring secure electrical connection without requiring manual dexterity or effort, thereby improving ease of operation while maintaining connection security.
3Productivity
If automated tension lock mechanism is introduced, then the installation efficiency is improved, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the automated locking mechanism into distinct functional modules: the rotating shaft for actuation, the cam structure for motion conversion, the tension lock components for securing, and the guide features for alignment. Each segment performs a specific function, making the overall complex mechanism manageable, manufacturable, and maintainable while achieving high installation efficiency through automation.

AI summary
The application belongs to the technical field of LED display screen box assembly, and relates to a tension lock and LED display screen box. The tension lock comprises a base, a rotating shaft, a shim and a knob, wherein the base is provided with a sliding hole, one end of the rotating shaft is fixedly connected with the knob, the other end of the rotating shaft is inserted into the sliding hole, the shim is rotationally connected with the rotating shaft, and the distance between the shim and the knob is kept constant; Turning the knob can make the rotating shaft rotate and slide along the axial direction of the sliding hole to make the shim move away from or close to the base. The tension lock can effectively improve the installation efficiency of LED display screen box.
