Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless charging is performed in the first mode, then charging convenience is improved, but curved deformation of the display panel occurs
Solution Approach 1:
The patent applies the dynamics principle by making the supporting member movable rather than fixed. The supporting member transitions between a first position (providing curvature for display flexibility) and a second position (providing flat support to prevent deformation during wireless charging). This dynamic adjustment allows the system to adapt its structural characteristics based on operational mode, resolving the contradiction between charging convenience and display panel shape stability.
2Stability of the object's composition
If the supporting member maintains curved shape, then display flexibility is improved, but wireless charging efficiency deteriorates
Solution Approach 1:
The supporting member dynamically changes its position based on operational requirements. During wireless charging, it moves to a second position that provides flat support, ensuring efficient charging. During display operation, it returns to a first position that maintains curved shape for display flexibility. This dynamic repositioning resolves the contradiction between display flexibility and wireless charging efficiency.
Solution Approach 2:
The supporting member is divided into multiple segments or regions with different functions. One region provides curved support for display flexibility while another region can be adjusted to provide flat support for wireless charging. This segmentation allows different parts of the supporting structure to serve different purposes simultaneously or sequentially, resolving the contradiction between display flexibility and charging efficiency.
3Adaptability or versatility
If the wireless charging coil is always exposed, then charging availability is improved, but display panel deformation occurs
Solution Approach 1:
The wireless charging coil is integrated with a movable supporting member that can be dynamically positioned. When wireless charging is required, the supporting member moves to expose the coil. When display operation is prioritized, the supporting member moves to provide curved support, temporarily concealing the coil. This dynamic positioning ensures charging availability while preventing display deformation.
