Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If a light guide plate is used to transfer light efficiently, then optical efficiency is improved, but device complexity and cost increase

Engineering Contradiction:
Improveoptical efficiencyVSAvoiddevice complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The patent removes the light guide plate from the lighting system and replaces it with a reflection module that uses the housing structure itself to guide and reflect light. This extraction of the unnecessary component simplifies the device while maintaining optical efficiency through reflective surfaces integrated into the housing.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The housing structure is designed to serve multiple functions: it provides structural support, contains the light source, and acts as a light guide through its curved reflective surfaces. This multi-functionality eliminates the need for separate light guide plates and reduces overall device complexity.

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

2Illumination intensity

If multiple LED packages are applied to achieve high optical efficiency, then brightness is improved, but cost and device complexity increase

Engineering Contradiction:
ImprovebrightnessVSAvoiddevice complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The patent employs curved reflective surfaces within the housing that focus and distribute light from a single LED source uniformly across the emission area. The curvature of the reflection module directs light rays to achieve even illumination without requiring multiple LED packages, thereby reducing complexity while maintaining brightness.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Illumination intensity

If additional optical elements are added to prevent dark portions in curved areas, then uniformity of luminous intensity is improved, but cost and device complexity increase

Engineering Contradiction:
Improveuniformity of luminous intensityVSAvoiddevice complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

The curved reflective surfaces of the housing are specifically designed to redirect light into curved or bent emission areas, ensuring uniform luminous intensity distribution. The geometry of the reflection module naturally guides light around curves without requiring additional optical elements, maintaining uniformity while minimizing complexity.

Inventive Principle:
Principle #14Spheroidality (Curvature)

4Device complexity

If the number of optical elements is reduced, then device complexity is reduced, but optical efficiency may worsen

Engineering Contradiction:

Core Design Contradiction:
Device complexityVSUse of energy by moving object

Solution Approach 1:

The curved reflective surfaces are precisely engineered to maximize light redirection efficiency. By optimizing the curvature and angle of the reflection module, the system achieves high optical efficiency with minimal optical elements, as the geometry itself performs the light guiding function that would otherwise require complex optical components.

Inventive Principle:
Principle #14Spheroidality (Curvature)
