Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed frost component is used in a lighting device, then the structure is simple and easy to manufacture, but the lighting device cannot smoothly vary the level of frost lighting effect to meet different user demands

Engineering Contradiction:

Improvecapability to vary frost lighting effectVSAvoidsystem structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the frost components movable rather than fixed. The arm assemblies are designed to rotate and position frost components at different locations, enabling the lighting device to dynamically adjust the frost lighting effect from light to heavy levels according to different user demands and circumstances.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent divides the lighting device into multiple independent arm assemblies, each capable of independently positioning frost components. This segmentation allows each component to be controlled separately, providing fine-grained adjustment capability for the frost lighting effect while maintaining modular simplicity in the overall system architecture.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If multiple frost components are positioned to provide varying frost levels, then the adaptability to different lighting scenarios is improved, but the device complexity increases due to multiple movable arm assemblies

Engineering Contradiction:

Improveflexibility in lighting scenariosVSAvoidcontrol complexity

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The arm assemblies are designed with universal functionality to perform multiple operations: positioning frost components, adjusting frost levels, and adapting to different lighting scenarios. This multi-functionality reduces the need for separate specialized mechanisms, thereby maintaining ease of operation while achieving high adaptability across various lighting conditions.

Inventive Principle:

Principle #6Universality (Multi-functionality)
