Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a predefined curvature is used in curved display devices, then the structural stability is improved, but the adaptability deteriorates as users cannot change the curvature according to their needs
Solution Approach 1:
The patent implements a dynamic curvature adjustment mechanism where the back cover can transition between different curvature states (flat, mildly curved, highly curved) through a bending member assembly. This allows the display device to adapt to different user preferences while maintaining structural integrity through controlled mechanical movement of the support members and sliding member.
Solution Approach 2:
The patent changes the curvature parameter of the back cover from a fixed value to a variable parameter that can be adjusted by the user. Through the bending member, support members, and sliding member mechanism, the curvature radius and degree of curvature can be modified, enabling the same device to serve multiple display scenarios.
2Area of stationary object
If the panel size is increased, then the display area is improved, but the curvature control becomes more difficult due to increased panel curvature
Solution Approach 1:
The patent divides the back cover into multiple segments or zones that can be independently controlled by multiple bending members. This segmentation allows each section to be adjusted separately, making it easier to control the overall curvature of large-sized panels. The support members are positioned at different locations to provide distributed control points.
Solution Approach 2:
The patent introduces sliding members as intermediary components between the user and the support members. These sliding members provide mechanical advantage and ease of operation, allowing users to control the curvature of large panels with minimal effort. The sliding mechanism translates small user inputs into larger curvature adjustments.
3Manufacturing precision
If a fixed curvature structure is used, then the manufacturing precision is improved, but the ease of operation deteriorates as users cannot adjust the display angle
Solution Approach 1:
The patent transforms the static curvature structure into a dynamic one that can be adjusted by users. The bending member assembly with support members and sliding members enables the back cover to transition between different curvature states, allowing users to change display angles and viewing experiences while maintaining precise control through the mechanical design.
