Plug-in Lamp Holder Structure for String Lights
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional string lights have complex structures that make installation and removal inconvenient and increase production costs due to the need for metal screw holders.
Innovation Solution
A plug-in lamp holder structure with female metal jacks and male metal pins, along with clamping portions and strips, allows for easy assembly and disassembly, replacing the need for metal screw holders and simplifying the connection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal screw holders are used to connect bulbs to lamp holders, then the connection strength is improved, but the device complexity and production cost increase
Solution Approach 1:
The connection structure is segmented into separate functional components: the lamp holder body, the bulb base with external threaded portion, and the clamping mechanism. This allows the bulb to be screwed directly onto the lamp holder body without requiring a separate metal screw holder, simplifying the overall structure while maintaining connection strength through the distributed clamping force of multiple clamping plates
Solution Approach 2:
The metal screw holder is extracted/removed from the system entirely. Instead, the bulb base itself is designed with an external threaded portion that directly engages with the lamp holder body, eliminating the intermediate metal screw holder component and reducing structural complexity and production cost
2Stability of the object's composition
If metal screw holders are used to install LED lamp panels and light pipes, then the installation stability is improved, but the ease of manufacture and assembly deteriorate
Solution Approach 1:
The clamping mechanism uses movable clamping plates that can dynamically adjust to accommodate different bulb types and sizes. The spring-loaded or adjustable clamping plates provide stable holding force while allowing easy insertion and removal of bulbs, combining installation stability with ease of assembly
Solution Approach 2:
The mounting functions for LED lamp panels, light pipes, and bulbs are merged into a single integrated lamp holder structure. The lamp holder body combines the socket function, the mounting interface with external threaded portions, and the clamping mechanism, eliminating the need for separate metal screw holders and simplifying the manufacturing and assembly process
3Ease of operation
If plug-in structure with clamping plates is used, then the ease of operation for installation and removal is improved, but the connection strength may deteriorate
Solution Approach 1:
The bulb base is designed with a cylindrical shape and external threaded portion, allowing it to be easily screwed onto the lamp holder body in a rotational motion. The curved threading provides mechanical advantage for secure attachment while maintaining ease of operation. The cylindrical geometry also allows for smooth insertion and removal
Solution Approach 2:
The lamp holder body is pre-threaded with internal threads that match the external threaded portion of the bulb base. This preliminary preparation allows the bulb to be quickly and securely attached by simply screwing it on, without requiring additional fastening steps or complex assembly procedures
