Parallel Wire Light String with Series LED Linkage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing light string designs often suffer from false welding and poor contact at welding points due to the scattering and winding of wires, leading to loose welds and reduced light emission efficiency.
Innovation Solution
A light string configuration featuring a first wire, a second wire, and a third wire, where the light emitting devices are connected in series through the third wire, with the first and second wires being fixed to it, avoiding the need for winding and reducing light shading, thus preventing loose welds and enhancing light emission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If wires are wound together with the light string wires, then the scattered wires can be bundled, but the winding process causes loose weld at the welding point
Solution Approach 1:
The patent segments the wire management function from the light string structure by introducing a separate wire guide component. This allows wires to be organized without interfering with the welding process, resolving the contradiction between wire bundling stability and weld reliability.
Solution Approach 2:
The patent introduces a wire guide as an intermediary component that mediates between the scattered wires and the light string. This intermediary allows wires to be bundled while preventing interference with the welding process, thus maintaining both wire organization and weld integrity.
2Stability of the object's composition
If wires are wound together with the light string wires, then wire scattering is reduced, but light emission efficiency decreases due to increased light shading
Solution Approach 1:
The patent arranges wires and light strings in different spatial dimensions, with wires positioned in one layer and light strings in another. This dimensional separation allows wire bundling without light shading, resolving the contradiction between arrangement stability and light emission efficiency.
Solution Approach 2:
The wire guide acts as an intermediary that separates wire management from light emission spaces. This allows wires to be organized stably while preventing them from blocking light, thus maintaining both arrangement stability and light emission efficiency.
3Adaptability or versatility
If wires are scattered and wound, then wire routing is flexible, but false welding and poor contact occur at welding points
Solution Approach 1:
The patent separates wire routing from welding operations by using a wire guide component. This segmentation allows flexible wire routing in one area while maintaining precise welding conditions in another, resolving the contradiction between routing flexibility and welding precision.
Solution Approach 2:
The wire guide serves as an intermediary that enables flexible wire routing while preventing wire scattering from affecting welding precision. This intermediary maintains adaptability in wire placement while ensuring manufacturing precision at welding points.
