Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a lens array is disposed on the display panel to provide three-dimensional images, then three-dimensional image capability is improved, but resolution deteriorates

Engineering Contradiction:
Improvethree-dimensional image capabilityVSAvoidresolution
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The optical system is configured to be movable relative to the display panel, allowing dynamic adjustment between different optical path lengths. This enables the display device to switch between 2D and 3D modes, providing three-dimensional image capability without permanently degrading the resolution of two-dimensional images. The movable configuration allows the optical system to be positioned optimally for each mode.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If the optical path is adjusted for three-dimensional images, then three-dimensional image quality is improved, but two-dimensional image resolution deteriorates

Engineering Contradiction:
Improvethree-dimensional image qualityVSAvoidtwo-dimensional image resolution
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The optical system can be moved to different positions relative to the display panel. In the first position, the optical path length is optimized for high-quality three-dimensional images. In the second position, the optical system is configured to minimize interference with two-dimensional image display, thereby maintaining high resolution. This dynamic repositioning resolves the contradiction between 3D image quality and 2D image resolution.

Inventive Principle:
Principle #15Dynamics

3Stability of the object's composition

If the optical system is fixed for three-dimensional display, then three-dimensional image stability is improved, but adaptability to different observation distances deteriorates

Engineering Contradiction:
Improvethree-dimensional image stabilityVSAvoidadaptability to different observation distances
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The optical system is configured to be movable, enabling it to adapt to different observation distances by adjusting its position relative to the display panel. When the observer is at a farther distance, the optical system can be positioned to increase the optical path length, thereby extending the focal point. This dynamic adjustment maintains image stability across varying observation distances without requiring a fixed configuration.

Inventive Principle:
Principle #15Dynamics

4Adaptability or versatility

If the optical path length is increased for distant observers, then adaptability to distant observation is improved, but device complexity increases

Engineering Contradiction:
Improveadaptability to distant observationVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Instead of implementing a complex fixed optical system designed for distant observers, the patent employs a movable optical system that can be dynamically positioned. This allows the optical path length to be adjusted as needed, providing adaptability to distant observation without requiring a permanently complex device structure. The simplicity of the movable mechanism compared to a fixed complex system resolves this contradiction.

Inventive Principle:
Principle #15Dynamics
