Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a transparent display panel is designed to allow viewing from both front and rear sides, then the versatility and ease of operation are improved, but the device complexity increases due to the need for additional drive units and control mechanisms

Engineering Contradiction:
Improveviewing capabilityVSAvoiddrive unit structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The transparent display panel is designed to serve multiple viewing directions (front and rear) simultaneously, allowing the same display structure to fulfill multiple functions. The drive unit is configured to control the display panel for bidirectional viewing, enabling one system to handle multiple viewing scenarios without requiring separate display systems for each direction.

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

2Ease of operation

If touch input functionality is integrated into the transparent display panel, then the ease of operation is improved, but the device complexity increases due to additional sensor layers and control circuitry

Engineering Contradiction:
Improveuser interactionVSAvoidtouch input structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The touch input functionality is merged with the transparent display panel structure, combining the display and touch sensing functions into a single integrated unit. This allows the display panel to serve both as a visual output device and as a touch input interface, eliminating the need for separate touch sensors and reducing overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If augmented reality modes and internet connectivity features are added, then the adaptability and ease of operation are improved, but the device complexity increases due to additional processing units and communication modules

Engineering Contradiction:
Improveapplication functionalityVSAvoidcontrol system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The controller is designed to manage multiple application modes including augmented reality and internet connectivity functions, allowing a single control system to handle diverse operational requirements. This multi-functional approach enables the display panel to serve various purposes such as broadcast reception, web browsing, and AR applications without requiring separate dedicated systems for each function.

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