Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a foldable display is designed with basic display functionality only, then the device structure remains simple, but the versatility and user functionality are limited
Solution Approach 1:
The display device integrates multiple functions including fingerprint recognition, film scanning, transparency adjustment, and communication capabilities into a single foldable display system. The controller unit coordinates these diverse functions through a unified architecture, allowing the display to serve as both a viewing interface and a multifunctional processing device, thereby achieving multi-functionality without proportionally increasing structural complexity.
Solution Approach 2:
The patent combines previously separate functions (fingerprint sensor, film scanner, display, communication module) into an integrated foldable display device. The controller unit merges the coordination of these components, and the foldable form factor allows physical integration of multiple functional layers within a compact structure, reducing overall system complexity while enhancing versatility.
2Ease of operation
If transparency adjustment functionality is added to the foldable display, then user experience is improved, but the device complexity increases
Solution Approach 1:
The display incorporates a transparency adjusting layer that can dynamically change its optical properties based on user input. This layer transitions between transparent and opaque states through electrical control, allowing the display to adapt its functionality in real-time without requiring physical reconfiguration or additional manual mechanisms, thereby improving ease of operation with minimal structural overhead.
Solution Approach 2:
The transparency of the display is controlled by changing the optical parameters of the transparency adjusting layer through electrical signals. By modulating the layer's transparency parameter in response to user input, the system achieves dynamic control over display visibility and privacy without adding mechanical complexity, as the parameter change is achieved through electronic control rather than physical modification.
3Adaptability or versatility
If multiple additional features (fingerprint recognition, communication device, film scanner) are integrated, then the versatility of the display is enhanced, but the device complexity and manufacturing difficulty increase
Solution Approach 1:
The patent divides the integrated system into distinct functional modules: display element, transparency adjusting layer, fingerprint recognition unit, film scanner, and communication device, all coordinated by a controller unit. This modular segmentation allows each component to be manufactured and tested independently before final integration, reducing overall manufacturing complexity while maintaining the versatility benefits of having multiple integrated features.
Solution Approach 2:
The controller unit serves as a universal coordination center that manages multiple diverse functions (display control, fingerprint authentication, film scanning operations, communication protocols, and transparency adjustment). By consolidating the control logic for all these features into a single unified controller, the patent reduces the need for separate control circuits and interfaces, thereby easing manufacturing while preserving full versatility.
