Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display screen is made large to allow comfortable viewing, then viewing comfort is improved, but space utilization deteriorates when the device is not in use
Solution Approach 1:
The display device employs a flexible display screen that can dynamically change its configuration between flat (deployed) and curved/convex (stored) states. This dynamic transformation allows the screen to occupy minimal space during storage while providing full viewing area when in use, directly resolving the contradiction between large display area and compact storage.
Solution Approach 2:
The flexible display screen is designed to conform to and nest within the base structure when in the stored configuration. The screen effectively nests itself within the device footprint by curving along the base structure, minimizing the overall space occupied while maintaining the ability to unfold to full size when needed.
2Ease of operation
If the display device automatically adjusts configuration based on user presence, then viewing convenience is improved, but device complexity increases
Solution Approach 1:
The display device incorporates sensors that automatically detect user presence and gaze direction, enabling the system to self-adjust its configuration without manual input. The processor interprets sensor data and autonomously controls the actuators to position the display optimally, making the device serve itself and eliminating the need for complex user interfaces or manual adjustment mechanisms.
Solution Approach 2:
The system uses sensors to continuously monitor user presence and gaze direction, providing real-time feedback to the processor. This feedback loop enables automatic adjustment of the display configuration to maintain optimal viewing conditions, resolving the contradiction by using intelligent automation rather than mechanical complexity.
3Area of stationary object
If the flexible display screen is bent to change configurations, then space utilization is improved, but manufacturing precision requirements increase
Solution Approach 1:
The system dynamically changes the geometric parameters of the display screen by controlling the degree and direction of bending through actuators. The processor adjusts bending parameters based on detected user presence and configuration needs, allowing precise control over the screen's shape without requiring extremely tight manufacturing tolerances on the flexible display itself.
Solution Approach 2:
The flexible display screen is designed with inherent flexibility that allows it to be dynamically bent into different configurations during operation. This dynamic capability reduces the need for precision-manufactured fixed structures, as the screen can adapt its shape through controlled bending rather than requiring precise pre-fabricated forms.

AI summary
A display device includes a flexible display screen and one or more actuators. The one or more actuators are configured to induce bending of the flexible display screen in a first direction to move the flexible display screen between a first configuration and a second configuration, wherein the flexible display screen is one of flat or concave in the first direction in the first configuration, and the flexible display screen is convex in the first direction in the second configuration. The one or more actuators are activatable to move the flexible display screen between the first configuration and the second configuration by one of a sensor output from one or more sensors, a request from a software application, or a command from a subject.
