Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for connecting LED light emitting elements to a power supply often result in electric shocks and unintentional disconnection or detachment due to insecure wire connections, particularly in high-position installations like down lights.
Innovation Solution
A plug-in power adapter comprising a main body, bottom cover, adapting cylinder, anode and cathode clips, gasket, and connecting members that securely clamp the power cable ends, ensuring stable electrical conductivity and preventing loosening or separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wire connections are made directly to power cable for LED installation, then installation is simple, but connection security deteriorates causing electric shocks and unintentional disconnection
Solution Approach 1:
The patent introduces a lamp holder as an intermediary component between the LED light emitting element and the power cable. The lamp holder provides a secure mounting structure with screw terminals that properly connect the wire connections to the power cable, eliminating direct wire connections while maintaining installation simplicity. This mediator resolves the contradiction by providing both ease of installation and connection security.
2Ease of operation
If lamp holder is installed at high position for down light, then lighting function is achieved, but connection stability deteriorates due to gravity and external forces
Solution Approach 1:
The patent employs a spring mechanism with curved elastic deformation capability to provide resilient clamping force. The spring's curved structure allows it to deform and maintain constant contact pressure on the power cable, preventing disconnection due to gravity and external forces at high installation positions. This curvature-based design resolves the contradiction between installation flexibility and connection stability.
3Device complexity
If conventional wire connection method is used, then device complexity is low, but safety deteriorates due to electric shock risk
Solution Approach 1:
The lamp holder serves as an intermediary that isolates the user from direct contact with live wires during installation and operation. The screw terminal structure within the lamp holder provides a safe, enclosed connection point that eliminates exposed wire ends, reducing electric shock risk while adding minimal complexity to the overall system.
4Reliability
If lamp holder is used to secure LED element, then connection reliability improves, but device complexity increases due to additional components
Solution Approach 1:
The lamp holder is designed to perform multiple functions: mechanically securing the LED light emitting element, providing electrical connection terminals for wire connections, and offering a mounting interface for the power cable. By consolidating these functions into a single component, the patent achieves connection reliability without proportionally increasing device complexity.

AI summary
Disclosed is a plug-in power adapter connectable into a screwing portion of a conventional lamp holder by a screwing connection, and power is supplied to the power adapter, and the power adapter is provided for connecting a power cable of an electric appliance to supply power to the electric appliance. When two bare ends of the power cable are connected to the power adapter and clamped by two wire clipping ends respectively to prevent the power cable from falling out easily, so as to achieve the effects of connecting the power cable securely and preventing the cable from being loosened or separated by external forces.
