Innovation Solution

A display device with a transparent display panel featuring a plurality of plates that rotate to open or close the rear, controlled by a motor and sensor system, allowing for light-transmitting or light-blocking modes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If a transparent display panel is used to allow users to see behind it, then transparency and visibility are improved, but the ability to block light and display images is reduced

Engineering Contradiction:
ImprovetransparencyVSAvoidlight-blocking capability
Core Design Contradiction:
Illumination intensityVSAdaptability or versatility

Solution Approach 1:

The patent applies the dynamics principle by implementing a dynamic blind assembly that can rotate between different angular positions. The blinds transition from a horizontal state (allowing transparency) to a vertical state (providing light-blocking capability), enabling the display device to adapt its optical properties based on operational requirements. This dynamic reconfiguration resolves the contradiction between transparency and light-blocking capability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent segments the blind assembly into multiple independently rotatable blind bars arranged in arrays. This segmentation allows different portions of the display to be controlled independently, enabling selective transparency and light-blocking in different regions. The segmented structure facilitates the transition between transparent and light-blocking modes while maintaining overall system versatility.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If blinds are added to control transparency and light-blocking, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improvemode switching capabilityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements multi-functionality by designing the blind assembly to perform multiple functions: controlling transparency, blocking light, and potentially displaying information. The same rotational mechanism serves both transparency control and light-blocking purposes, reducing the need for separate systems. This universal approach improves adaptability while minimizing the increase in device complexity.

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

Solution Approach 2:

The patent employs thin, flexible blind bars that can be easily rotated and repositioned. These thin-film structures minimize the added bulk and complexity while maintaining effective light control. The flexible nature of the blind bars allows for simple rotational actuation mechanisms, reducing overall structural complexity despite the enhanced adaptability.

Inventive Principle:
Principle #30Flexible shells and thin films

3Manufacturing precision

If sequential rotation of plates is implemented, then manufacturing precision is improved, but device complexity increases

Engineering Contradiction:
Improverotation control precisionVSAvoidcontrol mechanism complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent incorporates feedback mechanisms to monitor and control the rotational position of each blind bar. Sensors detect the angular position of individual plates, providing real-time feedback to the control system. This feedback enables precise control of the sequential rotation process, ensuring that each plate rotates to the correct position while maintaining manufacturing precision. The feedback loop compensates for variations and maintains accuracy despite the increased control complexity.

Inventive Principle:
Principle #23Feedback
