Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple light emitting modules are added to provide visual effects, then the lighting function and user engagement are improved, but the production cost increases

Engineering Contradiction:

Improvelighting functionVSAvoidproduction cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent applies local quality by creating protrusion patterns at specific locations on the housing surface rather than uniformly distributing light emitting modules throughout. The protrusions are strategically positioned to reflect light in desired directions, providing effective visual effects while minimizing the total number of LED modules required, thus reducing production costs.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent introduces protrusion patterns as an intermediary element between the light emitting modules and the external environment. These protrusions act as mediators that redirect and amplify the light output, allowing fewer LED modules to achieve the same visual impact as many more modules would produce directly, thereby resolving the cost-effectiveness contradiction.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If light emitting modules are added to provide visual effects, then the lighting function is improved, but the device complexity increases

Engineering Contradiction:

Improvelighting functionVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of adding complex lighting structures throughout the device, the patent applies local quality by incorporating protrusion patterns only at specific strategic locations on the housing. This localized approach provides effective lighting functions while maintaining simplicity in the overall device structure, avoiding unnecessary complexity.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent inverts the conventional approach by not directly exposing light emitting modules to view, but instead using protrusions to reflect and redirect light outward. This indirect lighting method achieves visual effects while keeping the light emitting modules concealed within the housing, simplifying the overall device structure.

Inventive Principle:

Principle #13The other way round (Inversion)

3Illumination intensity

If protrusion patterns are added to reflect light, then the visual effect is enhanced, but the manufacturing complexity increases

Engineering Contradiction:

Improvevisual effectVSAvoidmanufacturing process

Core Design Contradiction:

Illumination intensityVSEase of manufacture

Solution Approach 1:

The patent applies local quality by adding protrusion patterns only at specific strategic locations on the housing surface rather than across the entire surface. This localized modification enhances visual effects through targeted light reflection while minimizing the overall manufacturing complexity, as only specific areas require additional processing.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The protrusion patterns can be implemented as simple molded features or attached elements that are inexpensive to produce. By using simple geometric protrusions rather than complex optical components, the patent enhances visual effects while keeping manufacturing processes simple and cost-effective.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
