Wavy-Wire LED Light Strip for Multi-Directional Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing LED light strips are limited to bending in one direction due to the compression or stretching of main wires, which can lead to wire breakage and restrict their use scenarios.
Innovation Solution
The LED light strip features a core wire with a groove and two main wires on both sides having a wavy curve structure, with LED light strings and an insulation wrap, and a FPCB board with wavy curve connections, allowing multiple directions of bending.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light strip is bent in a direction other than the preset bending direction, then the light strip can be installed in more positions, but one of the main wires will be compressed and the other stretched, which may cause wire breakage
Solution Approach 1:
The patent applies curvature by forming the main wires into a wavy curve structure instead of straight lines. This wavy configuration allows the wires to accommodate bending forces in multiple directions without experiencing excessive compression or tension that would lead to breakage. The curved geometry distributes mechanical stress more evenly along the wire length.
Solution Approach 2:
The patent changes the geometric parameter of the main wires from straight to wavy curved configuration. This parameter change enables the wires to flex and deform in multiple directions while maintaining structural integrity. The wavy curve structure allows the wires to absorb bending forces through controlled deformation rather than experiencing concentrated stress points.
2Adaptability or versatility
If the main wires are arranged in a straight configuration, then the wire structure is simple, but the light strip cannot be bent in multiple directions
Solution Approach 1:
The patent introduces curvature to the main wire structure, transforming them from straight to wavy curved configurations. This curvature enables multi-directional bending capability while the wavy pattern itself becomes the defining structural feature. The curved geometry allows the wires to flex naturally in various directions without requiring complex additional components.
3Reliability
If the light strip uses a rigid structure to maintain wire integrity, then the wire breakage risk is reduced, but the light strip cannot be bent in multiple directions
Solution Approach 1:
The patent uses a wavy curved structure for the main wires that combines flexibility with breakage resistance. The curved configuration allows the wires to bend in multiple directions while the wavy pattern distributes mechanical stress, preventing localized stress concentration that would cause breakage. This geometric design enables the wires to be both flexible and durable.
Solution Approach 2:
The patent changes the wire configuration parameter from straight to wavy curved, which fundamentally alters how the wires respond to bending forces. This parameter change allows the wires to accommodate multi-directional bending while maintaining structural integrity through controlled deformation patterns that prevent breakage.
