Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If LCD screens are used to create animations, then high resolution is achieved, but the cost increases and sensitivity to environmental conditions worsens

Engineering Contradiction:
ImproveresolutionVSAvoidsensitivity to environmental conditions
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent uses light guides with etched patterns to create optical copies of animation frames instead of using LCD screens. The light guides reflect light according to etched patterns to display animated images, replacing the LCD technology with a more robust optical system that is less sensitive to environmental conditions while maintaining high resolution

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent employs light guides made from inexpensive materials such as acrylic or polycarbonate that can be etched with patterns. These light guides are cheaper than LCD screens and can be replaced if needed, providing a cost-effective solution that maintains high resolution while reducing sensitivity to environmental factors

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Stability of the object's composition

If rigid luminous modules are used, then structural stability is maintained, but ease of integration into various equipment worsens

Engineering Contradiction:
Improvestructural stabilityVSAvoidease of integration
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent uses flexible light guides that can be bent and shaped to fit into various equipment configurations. The light guides maintain their optical functionality while being flexible, allowing easy integration into different types of equipment without compromising structural stability of the overall module

Inventive Principle:
Principle #30Flexible shells and thin films

3Adaptability or versatility

If multiple light sources are used to project multiple patterns, then animation capability is improved, but device complexity and footprint increase

Engineering Contradiction:
Improveanimation capabilityVSAvoidnumber of light sources
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple pattern projections into a single light guide system where different patterns are etched on the same light guide. A single light source illuminates the light guide, and the etched patterns on the light guide create multiple distinct visual patterns simultaneously, reducing the number of light sources needed while maintaining animation capability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent uses the dimensional space of the light guide surface to encode multiple patterns through etching. By creating patterns in the two-dimensional surface of the light guide, the system can display multiple patterns without adding more light sources in the third dimension, thus reducing device footprint and complexity

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
