Solution Overview

Problem

Existing LED light strips are limited to top bending and cannot effectively bend in multiple directions due to the arrangement of main wires, which either compress or stretch, preventing flexible deformation.

Innovation Solution

The LED light strip is designed with a core wire groove and main wires arranged in a spiral curve structure, along with connecting members having a similar spiral curve or zigzag wire structure, enhancing bending resistance and allowing multi-directional bending.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If main wires are arranged parallel to the surface of the light strip, then the light strip can be easily manufactured, but the light strip can only be bent in one direction (top bending) and cannot be side bent

Engineering Contradiction:
Improveease of manufactureVSAvoidbending direction
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The main wires are designed with a spiral curve structure instead of being straight or parallel. This curved configuration allows the wires to flex and accommodate bending forces from multiple directions without breaking, enabling the light strip to be bent in any direction while maintaining electrical connectivity.

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Adaptability or versatility

If main wires are arranged to allow side bending, then multi-directional bending is possible, but one main wire will be compressed and the other stretched, preventing sufficient elastic force generation

Engineering Contradiction:
Improvebending directionVSAvoidbending resistance
Core Design Contradiction:
Adaptability or versatilityVSStrength

Solution Approach 1:

The spiral curve structure of the main wires distributes the compressive and tensile stresses more evenly along the wire length. The curved geometry allows the wires to elongate and compress in a controlled manner during side bending, generating sufficient elastic force while maintaining structural integrity.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The wire configuration changes from straight/parallel to spiral curved, fundamentally altering how the wires respond to bending forces. This parameter change enables the wires to generate adequate elastic force during side bending by utilizing the mechanical properties of curved structures under load.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If the light strip structure is made more complex to enable multi-directional bending, then bending versatility improves, but the device complexity increases

Engineering Contradiction:
Improvebending directionVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The solution achieves multi-directional bending capability through a relatively simple modification: configuring the main wires in a spiral curve pattern. This elegant geometric solution provides versatile bending functionality without requiring complex mechanisms, multiple components, or complicated structural arrangements.

Inventive Principle:
Principle #14Spheroidality (Curvature)
