Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If complex structured light bodies made of many materials are used, then lighting functionality is achieved, but manufacturing complexity and ecological footprint increase

Engineering Contradiction:
Improvemanufacturing complexityVSAvoidlight body structure
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The patent extracts and removes unnecessary complex structural elements from traditional light bodies. By using a simple frame structure made from a single material (cardboard or paperboard), the design eliminates multiple materials and complex assemblies, achieving easier manufacturing while maintaining lighting functionality through strategic placement of LED modules.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies homogeneity by constructing the entire light body frame from a single material type (cardboard or paperboard). This uniform material approach simplifies manufacturing processes, reduces material handling complexity, and improves ecological performance compared to multi-material constructions, while still achieving the required structural and functional goals.

Inventive Principle:
Principle #33Homogeneity

2Adaptability or versatility

If cardboard material is used for the lamp frame, then ecological performance improves, but design options are limited to circular structures

Engineering Contradiction:
Improvedesign optionsVSAvoidstructural limitations
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the light body into a modular frame structure made from cardboard or paperboard, which can be configured in various geometric patterns. This segmentation allows the same material to be used in different shapes (rectangular, square, triangular, etc.) and sizes, providing extensive design flexibility while maintaining ecological performance and simplifying manufacturing through standardized components.

Inventive Principle:
Principle #1Segmentation

3Strength

If traditional materials are used for light bodies, then structural strength is achieved, but ecological footprint increases

Engineering Contradiction:
Improvestructural strengthVSAvoidecological footprint
Core Design Contradiction:
StrengthVSObject-generated harmful factors

Solution Approach 1:

The patent changes the material parameter from traditional plastic or metal to cardboard or paperboard, which has significantly lower ecological footprint. By optimizing the frame geometry, thickness, and structural configuration, the design achieves adequate structural strength for supporting LED modules while using these eco-friendly materials, thus reducing harmful environmental factors without sacrificing necessary mechanical properties.

Inventive Principle:
Principle #35Parameter changes
