Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the screen size is increased to provide more services and functions, then the user experience and functionality are improved, but the screen size is limited by components such as cameras, sensors, and buttons located in traditional positions
Solution Approach 1:
The patent transitions from a traditional rigid flat-screen layout to a flexible foldable display that utilizes three-dimensional space. The display can be folded along a hinge axis, enabling the screen to extend beyond the conventional planar boundaries of the device housing. This dimensional change allows the screen area to effectively increase while maintaining a compact form factor when folded, resolving the contradiction between screen size and device adaptability.
Solution Approach 2:
The display structure is made dynamic through the foldable mechanism, allowing it to transition between folded and unfolded states. This dynamic configuration enables the screen to adapt its effective area based on usage requirements - providing a larger display area when needed and a compact form when portability is required. The flexible support sheet and hinge mechanism enable this dynamic transformation, allowing the system to optimize between screen size and device versatility.
2Ease of operation
If a flexible display is used to enable folding, then the screen can be folded and unfolded seamlessly, but the display requires a support structure to maintain its shape in folded regions
Solution Approach 1:
The patent employs a flexible support sheet as a thin-film structure to provide structural support to the display in folded regions. This flexible support sheet can bend and conform to the folded configuration while maintaining the integrity and shape of the display. The thin-film nature of the support structure minimizes added complexity while providing the necessary mechanical support for the flexible display to maintain its shape during folding and unfolding operations.
Solution Approach 2:
The flexible support sheet acts as an intermediary element between the flexible display and the rigid housing structure. It provides the necessary mechanical support and shape maintenance for the display in folded regions without requiring complex rigid support structures. The support sheet mediates between the flexibility needed for folding and the structural integrity needed for shape maintenance, simplifying the overall device structure while enabling folding capability.
