Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If conventional protective tube is used to house internal circuitry, then the light wire is protected from environmental hazards, but the protective tube provides little mechanical strength and allows water and dust penetration

Engineering Contradiction:
Improveenvironmental protectionVSAvoidmechanical strength
Core Design Contradiction:
Object-affected harmful factorsVSStrength

Solution Approach 1:

The patent uses a composite structure consisting of a flexible printed circuit board (FPC) as the base substrate, LED modules mounted on it, and a transparent encapsulant material covering the entire assembly. This composite structure provides both environmental protection and mechanical strength, resolving the contradiction between protection and strength.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The patent employs a flexible printed circuit board (FPC) as the base structure and uses a transparent encapsulant film to protect the internal components. This flexible shell approach provides adequate mechanical protection while maintaining flexibility and environmental resistance.

Inventive Principle:
Principle #30Flexible shells and thin films

2Object-affected harmful factors

If conventional sheet or hard lamination process is used to encapsulate light wire, then the light wire is protected, but the manufacturing process is labor intensive and decreases flexibility

Engineering Contradiction:
ImproveprotectionVSAvoidmanufacturing complexity
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The patent replaces the conventional mechanical sheet or hard lamination encapsulation process with a transparent encapsulant material that is applied and cured to form a protective layer. This substitution simplifies the manufacturing process, reduces labor intensity, and maintains flexibility of the light wire.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the physical state and properties of the encapsulant material through curing processes, transforming it from a liquid or soft state to a solid protective layer. This parameter change enables automatic manufacturing processes while maintaining flexibility and protection.

Inventive Principle:
Principle #35Parameter changes

3Object-affected harmful factors

If conventional sheet or hard lamination process is used to encapsulate light wire, then the light wire is protected, but the manufacturing process is time-consuming

Engineering Contradiction:
ImproveprotectionVSAvoidmanufacturing speed
Core Design Contradiction:
Object-affected harmful factorsVSProductivity

Solution Approach 1:

The patent replaces time-consuming mechanical lamination processes with a curing-based encapsulation process that can be automated. The transparent encapsulant material is applied and then cured through UV exposure or other curing methods, significantly reducing manufacturing time and increasing productivity.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent integrates the encapsulation process into the manufacturing flow by applying the transparent encapsulant material during assembly and curing it immediately. This preliminary action eliminates separate protection steps and accelerates the overall manufacturing process.

Inventive Principle:
Principle #10Preliminary action

4Device complexity

If conventional light wire structure is used, then the design is simple, but the lighting functionality is limited and uniform lighting is not achieved

Engineering Contradiction:
Improvestructural simplicityVSAvoidlighting uniformity
Core Design Contradiction:
Device complexityVSIllumination intensity

Solution Approach 1:

The patent uses individual LED modules mounted on the flexible printed circuit board, each emitting light in specific directions. The transparent encapsulant material distributes and diffuses the light uniformly across the entire light wire surface, achieving uniform lighting while maintaining structural simplicity.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent transitions from point-source lighting to a distributed light-emitting surface by embedding LED modules in the flexible circuit board and using the transparent encapsulant to diffuse light in multiple dimensions. This creates uniform illumination across the entire wire surface.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
