Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If dedicated tooling and remodelling are used for each size and shape, then manufacturing precision is improved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improvehousing dimensions and shape precisionVSAvoidnumber of tools and components
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a modular housing system where standardized profile parts and corner parts with coupling elements can be combined in multiple configurations to create housings of different sizes and shapes. This single modular system replaces the need for dedicated tooling for each specific housing variant, allowing one set of components to serve multiple functions and produce various luminaire configurations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The housing is segmented into discrete modular components - profile parts and corner parts - that can be independently manufactured and then assembled. This segmentation allows each component to be produced with standard tooling while the final housing configuration can be customized by selecting and combining different numbers and types of modules, thereby maintaining manufacturing precision without requiring dedicated tooling for each housing variant.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If fixed parameters are used for luminaire housing, then manufacturing simplicity is improved, but adaptability to different mounting and illumination scenarios deteriorates

Engineering Contradiction:
Improvehousing production simplicityVSAvoidmounting and illumination scenario flexibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies dynamics by creating a housing system that can be dynamically reconfigured to suit different mounting and illumination scenarios. The modular profile and corner parts can be assembled in various configurations to adapt to different ceiling or wall mounting requirements and light distribution needs, allowing the housing to transition between different functional states while maintaining ease of manufacture through standardized components.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The modular components are designed with universal coupling elements that enable the same basic parts to serve multiple functions across different applications. The profile parts and corner parts can be combined to create housings suitable for various mounting locations (ceiling, wall) and illumination patterns, making the manufacturing system universally applicable to diverse scenarios without requiring specialized fixed-parameter housings for each case.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If modular framework is used for flexible configuration, then adaptability is improved, but structural stability may deteriorate

Engineering Contradiction:
Improvehousing shape and size flexibilityVSAvoidframework stability
Core Design Contradiction:
Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The framework is segmented into profile parts and corner parts that connect through coupling elements. This segmentation enables flexible configuration while the coupling elements are designed to provide rigid mechanical connections that ensure structural stability. Each segment can be independently positioned to achieve the desired configuration, and the coupling mechanism maintains structural integrity through precise geometric interlocking and secure fastening.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The coupling elements incorporate curved or angled surfaces that provide mechanical interlocking between profile and corner parts. The geometric design of the coupling interfaces includes features such as recesses, protrusions, and angled contact surfaces that create stable mechanical connections, ensuring that the modular framework maintains structural rigidity and stability while allowing for flexible configuration through the arrangement of modular components.

Inventive Principle:
Principle #14Spheroidality (Curvature)
