Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If components such as optical sensors are disposed under the screen to improve screen-to-body ratio, then the screen-to-body ratio is improved, but the light transmittance requirements for different optical sensors cannot be simultaneously satisfied

Engineering Contradiction:
Improvescreen-to-body ratioVSAvoidlight transmittance requirements
Core Design Contradiction:
Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The display panel is divided into multiple regions with different transmittance characteristics. A first region has a first transmittance and a second region has a second transmittance, allowing different optical sensors to be placed in different regions according to their specific light transmittance requirements while maintaining a high screen-to-body ratio overall

Inventive Principle:
Principle #3Local quality

2Device complexity

If the display panel uses uniform transmittance across all areas, then the structure is simple, but different optical sensors cannot be accommodated with their varying transmittance requirements

Engineering Contradiction:

Solution Approach 1:

Different regions of the display panel are designed with different transmittance values to match the specific requirements of different optical sensors. This allows the display panel to accommodate multiple types of optical sensors with varying transmittance needs without requiring a completely complex multi-layer structure

Inventive Principle:
