Rotating Lamp Socket Switch Integrates Terminal Contact
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light sockets have complex structures with numerous components and multiple contact points, leading to increased assembly complexity, higher production costs, and reduced reliability due to the separate on-off switch mechanism and multiple points of electrical connection.
Innovation Solution
A simplified light socket design using fewer components, featuring an isolator seat with a seat bracket, end cover, connection guide terminal, turn switch, and connection port, where the turn switch controls terminal contact between the connection guide terminal and guide terminal to establish or disconnect electrical connections, reducing the number of contact points to three and incorporating a spring arm for biasing force.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate on-off switch mechanism with coil springs is used, then the switching function is achieved, but the device complexity increases and assembly steps increase
Solution Approach 1:
The patent combines the switch actuator and terminal contact into a single integrated component. The terminal contact serves dual functions: as an electrical conductor and as the switch actuator that opens or closes the circuit when rotated. This eliminates the need for separate coil springs and distinct switching mechanisms, thereby reducing device complexity while maintaining the switching function.
Solution Approach 2:
The terminal contact is designed to perform multiple functions simultaneously: it provides electrical connection and acts as the switching mechanism. By making the terminal contact universal, the patent eliminates redundant components and simplifies the overall structure without compromising the on-off switching capability.
2Reliability
If multiple contact points are used for electrical connection, then the electrical connection is established, but the number of components increases and production costs increase
Solution Approach 1:
The patent merges the functions of multiple contact points into a single terminal contact component. This terminal contact establishes electrical connection with both the live wire terminal and the neutral wire terminal, eliminating the need for separate contact components and reducing the total quantity of parts while maintaining reliable electrical connection.
3Ease of operation
If a separate on-off switch mechanism is embedded into the isolator seat, then the switching control is achieved, but the assembly steps increase and production costs increase
Solution Approach 1:
The patent integrates the switching control function directly into the terminal contact assembly. The terminal contact itself serves as the switch actuator, eliminating the need for separate embedding of switch mechanisms into the isolator seat. This integration simplifies the assembly process and reduces production steps while maintaining ease of operation through the rotational movement of the terminal contact.
4Adaptability or versatility
If numerous components are used in the light socket, then the functionality is complete, but the assembly complexity increases and productivity decreases
Solution Approach 1:
The patent combines multiple functional components into fewer integrated parts. The terminal contact serves as both the electrical conductor and the switch actuator, while the isolator seat provides both insulation and structural support. This reduction in component count directly improves assembly efficiency and productivity without sacrificing the complete functionality of the light socket.
Solution Approach 2:
By designing components with multiple functions, the patent reduces the total number of parts needed. The terminal contact's dual role as conductor and actuator, and the isolator seat's dual role as insulator and structural element, eliminates the need for separate dedicated components, thereby streamlining assembly and improving productivity.

Function Achieved in This Case
This design reduces the overall number of parts, simplifies the assembly process, lowers production costs, and enhances the reliability of electrical connections by reducing the complexity and number of contact points, while providing a more straightforward and efficient mechanism for power delivery.
Implementation Method 1
The terminal contact further has a spring arm that is in contact with the isolator seat and produces an upward biasing force for the turn rod

AI summary
A lamp bulb socket includes an isolator seat with a connection port, an end cover coupled with the isolator seat and having a bracket with a hole, a connection guide terminal with a first contact arm, a connection terminal, a guide terminal with a second contact arm, and a turn switch having a rod with gripping grooves at a first end and four arc notches at a second end opposite the first end. The arc notches received in the end cover and the first end held on the hold of the bracket. The turn switch further includes a terminal contact coupled to the four arc notches such that, when the rod is turned, the terminal contact opens or closes a connection between the connection terminal and guide terminal.
