Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple support rods are used between housings, then structural support is provided, but the flexible screen bending cannot be fully fitted causing touch discomfort and reduced service life
Solution Approach 1:
The support structure is segmented into multiple components: support rods for rigid support, composite supporting layer (including bendable tensile layer and bendable flattenable supporting layer) for adaptive bending support, and supporting plates. This segmentation allows each component to perform its specific function, collectively achieving both structural strength and flexible screen protection.
Solution Approach 2:
The patent employs materials and structures with variable parameters - the composite supporting layer can change from a flattened state (providing rigid support) to a bent state (fitting the flexible screen curvature). The elastic mechanism also changes its mechanical properties based on the folding state, providing appropriate support force during different phases of the folding process.
2Stability of the object's composition
If support rods are used for supporting, then structural stability is achieved, but the bending of flexible screen during folding is not fully fitted causing touch discomfort
Solution Approach 1:
The support structure transitions from a static configuration to a dynamic one that adapts during folding. The composite supporting layer with its bendable tensile layer and bendable flattenable supporting layer dynamically changes shape during the folding process, ensuring the flexible screen is properly supported in both folded and unfolded states, thereby maintaining both stability and touch comfort.
Solution Approach 2:
The composite supporting layer acts as an intermediary between the rigid support rods and the flexible screen. It translates the rigid support forces into adaptive pressure distribution that conforms to the flexible screen's bending shape, ensuring both structural stability and proper fitting during folding operations.
3Manufacturing precision
If a composite supporting layer with bendable tensile layer and bendable flattenable supporting layer is used, then bending fitting is improved, but device complexity increases
Solution Approach 1:
The patent uses composite materials - specifically a composite supporting layer comprising a bendable tensile layer and a bendable flattenable supporting layer. This composite structure achieves superior bending fitting precision by combining the properties of different materials, while the layered design allows for controlled deformation characteristics that simplify the overall folding mechanism.
