Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If flexible display panels are used to enable bending and folding, then adaptability and versatility are improved, but device complexity increases due to additional sensing and control mechanisms

Engineering Contradiction:
Improvebending and folding capabilityVSAvoidsensing and control mechanisms
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display panel serves multiple functions: it acts as both the display surface and the sensing element for detecting bending and folding states. The same flexible display structure that enables adaptability also provides the sensing capability, eliminating the need for separate complex sensing mechanisms and thereby reducing overall device complexity while maintaining versatility

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

2Measurement precision

If multiple sensors are added to detect bending, grip, and gaze, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improvebending detection accuracyVSAvoidsensor quantity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

Multiple sensing functions (bending detection, grip detection, gaze detection) are merged into an integrated sensing system within the display apparatus. The display panel itself is configured to detect multiple user inputs simultaneously, combining what would traditionally require separate sensors into a unified structure, thereby maintaining measurement precision while reducing overall device complexity

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If the display interface is dynamically adjusted based on user inputs, then ease of operation is improved, but device complexity increases due to control mechanisms

Engineering Contradiction:
Improveintuitive controlVSAvoidcontrol mechanisms
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The display apparatus automatically detects user inputs (bending, grip, gaze) and adjusts the display interface without requiring separate control mechanisms or complex processing. The system serves itself by using the display panel's inherent sensing capability to directly control its own display output, thereby improving ease of operation while minimizing additional device complexity

Inventive Principle:
Principle #25Self-service
