Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If physical mounting and wiring of traditional canopy light fixtures is performed, then installation is completed, but installation time and complexity increase

Engineering Contradiction:

Improveinstallation easeVSAvoidinstallation time

Core Design Contradiction:

Ease of manufactureVSLoss of time

Solution Approach 1:

The lighting system is divided into modular components: a housing containing solid-state light generating elements, a removable diffuser lens, and independent control modules. This segmentation allows for easier installation and maintenance while enabling flexible reconfiguration of lighting patterns without complete fixture replacement.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements dynamically adjustable lighting parameters through independently controllable solid-state light generating elements. The system can change beam angles, color temperatures, and intensity levels electronically without physical modifications, transforming a static fixture into an adaptable lighting solution.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If diffuser lens is removed and re-mounted to alter light pattern, then light pattern changes, but time consumption increases

Engineering Contradiction:

Improvelight pattern adaptabilityVSAvoidadjustment time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system uses independently controllable solid-state light generating elements that can be electronically adjusted to produce different light patterns, beam angles, and color temperatures. This dynamic control eliminates the need for physical diffuser lens removal and reinstallation, allowing instant reconfiguration of lighting characteristics.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes lighting parameters (beam angle, color temperature, intensity) by controlling the solid-state light generating elements rather than physically altering the fixture structure. This parameter-based adjustment enables versatile light pattern modification without mechanical intervention.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If physical retrofit is performed to alter light settings, then light settings are changed, but fixture complexity increases

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lighting fixture is segmented into independent controllable modules with solid-state light generating elements. Each module can be controlled separately to achieve different lighting effects, providing high adaptability while maintaining a relatively simple overall structure that requires no physical retrofitting.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent replaces mechanical adjustment methods (physical diffuser lens removal, structural modifications) with electronic control of solid-state light generating elements. This substitution reduces mechanical complexity while enhancing the ability to adjust light settings and patterns.

AI summary

A solid-state canopy light fixture is provided herein having independently controllable sets (and subsets) of solid-state light generating elements to alter light patterns particularly to generate different light temperatures and different light beam angles. As recognized in the lighting industry, solid-state lighting may be rated based on CCT (correlated color temperature). The subject invention allows for CCT adjustment. In addition, the subject invention allows for light beams of different beam angles which allow for different areas of lighting (ranging from narrower to broader light beam angles). The subject invention allows for alteration of these light settings without physical retrofit of the light fixture.
