String Lamp Hanging Structure for Simplified Snap-Fit Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing RGB string lamp structure is complex and inconvenient to assemble due to the need for electrical connections between lamp beads and copper heads, and the use of end sealing rubber members for fixing lamp beads to light guide members.
Innovation Solution
A novel string lamp structure design featuring a lamp holder assembly with an arc-shaped bent member and locking protrusions for snap-fitting, integrated components for stable hanging, and a simplified assembly process without the need for metal terminals or end sealing rubber members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lamp beads are electrically connected to copper heads and fixed by end sealing rubber members, then electrical connection and fixation are achieved, but the structure becomes complex and assembly becomes inconvenient
Solution Approach 1:
The patent combines the electrical connection function and mechanical fixation function into a single integrated copper head structure. The copper head directly contacts the lamp bead's metal cap to establish electrical connection while its enlarged diameter provides mechanical retention, eliminating the need for separate end sealing rubber members and simplifying the overall structure.
Solution Approach 2:
The patent extracts and eliminates the end sealing rubber member from the assembly, as its functions (electrical connection and fixation) are already fulfilled by the copper head structure. This removal simplifies the assembly process and reduces structural complexity while maintaining reliability.
2Reliability
If multiple components (metal terminals, end sealing rubber members) are used for assembly, then electrical connection and fixation are secured, but assembly convenience deteriorates
Solution Approach 1:
The patent merges multiple components (metal terminals and end sealing rubber members) into a single integrated copper head structure that performs both electrical connection and mechanical fixation functions, thereby reducing the number of assembly steps and improving assembly convenience while maintaining assembly reliability.
Solution Approach 2:
The copper head is designed as a multi-functional component that simultaneously provides electrical connection (through contact with the lamp bead's metal cap) and mechanical fixation (through its enlarged diameter structure). This multi-functionality eliminates the need for separate components and simplifies the overall assembly process.
3Reliability
If a complex electrical connection structure with multiple components is used, then electrical connectivity is ensured, but the number of parts increases and assembly time increases
Solution Approach 1:
The patent combines multiple components required for electrical connection (metal terminals, end sealing rubber members) into a single copper head structure, reducing the total number of parts and assembly steps. This merging maintains electrical connectivity reliability while significantly improving assembly productivity.
Solution Approach 2:
The patent segments the functional requirements (electrical connection and mechanical fixation) and integrates them into a single copper head component rather than using multiple separate components. This functional integration reduces part count and assembly time while ensuring reliable electrical connectivity.
