Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a flexible display screen is made flexible and thin, then its portability and adaptability are improved, but its ease of operation for touch control is worsened
Solution Approach 1:
The supporting structure is designed to be dynamically changeable between planar and curved states. When touch control is needed, the structure transforms to a planar state to provide a stable surface for operation. When portability is needed, it transforms to a curved state for compact storage. This dynamic transformation resolves the contradiction between flexibility and ease of operation.
Solution Approach 2:
The patent changes the geometric parameters of the supporting structure by adjusting the relative positions and angles of its components. By changing the configuration from a curved state to a planar state, the surface characteristics are modified to enable proper touch control operation while maintaining the inherent flexibility of the display screen.
2Area of moving object
If a flexible display screen is made large-sized, then its display area is improved, but its ease of operation for click and touch control is worsened
Solution Approach 1:
The supporting structure dynamically adjusts its state based on operational needs. For large-sized flexible display screens, the structure transforms to a rigid planar state when touch control is required, providing sufficient stability across the entire display area. This allows large screens to maintain both extensive display area and operational ease through state transformation.
3Volume of moving object
If a flexible display screen is made flexible, then its storage compactness is improved, but its stability for touch control operation is worsened
Solution Approach 1:
The supporting structure exhibits dynamic stability characteristics. In the curved state, it occupies minimal storage volume while maintaining structural integrity. When transformed to the planar state, it provides a stable, rigid surface suitable for touch control operations. This dynamic adjustment resolves the contradiction between storage compactness and operational stability.
Solution Approach 2:
The supporting structure is divided into multiple segments or components that can be independently positioned and oriented. This segmentation allows the structure to transform between curved and planar configurations, enabling compact storage when curved and stable operation when planar, thus resolving the stability-volume contradiction.
