Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel is bent to form a curved surface television, then the visual field and viewing effect are improved, but the curvature becomes fixed and cannot be adjusted
Solution Approach 1:
The patent applies the dynamics principle by transforming the fixed curved surface into a dynamically adjustable one. The display panel is connected to a driving mechanism (motor, transmission elements, and elastic elements) that enables the curvature to change according to control signals. This allows the television to adapt between different curvature states, resolving the contradiction between adaptability and structural complexity by introducing controlled dynamic elements.
Solution Approach 2:
The driving mechanism is segmented into multiple independent components: a motor for power generation, transmission elements (gears, belts, or linkages) for force transmission, and elastic elements (springs or elastic bands) for curvature control. This segmentation allows each component to perform its specific function independently, making the overall system more manageable and easier to adjust while maintaining adaptability.
2Adaptability or versatility
If a motor and transmission mechanism are added to enable curvature adjustment, then adaptability is improved, but device complexity increases
Solution Approach 1:
The motor and transmission mechanism serve multiple functions: they provide power for curvature adjustment, control the direction of bending, and can be integrated with the existing display panel mounting structure. By designing the mechanism to perform multiple functions within a unified structure, the patent reduces overall complexity while maintaining adaptability.
Solution Approach 2:
The patent employs elastic elements such as springs or elastic bands as part of the curvature control mechanism. These flexible elements naturally provide the restoring force needed for bending without requiring complex mechanical structures, thereby reducing device complexity while enabling adjustable curvature through the motor-driven system.
3Adaptability or versatility
If the curvature is fixed during manufacturing, then manufacturing precision is maintained, but the television cannot meet different user viewing requirements
Solution Approach 1:
The patent incorporates elastic elements (springs or elastic bands) that are pre-loaded during manufacturing to provide a consistent initial curvature. This preliminary action ensures that the display panel starts with a precise, consistent curvature baseline, while the motor-driven mechanism allows users to adjust from this baseline without compromising the precision established during manufacturing.

Implementation Method 1
The motor rotates to pull a first end of the arc lever through the connector, so that the arc lever rotates around the pivot. The lever principle is used, so that a second end of the arc lever applies force to the casing
Implementation Method 2
The connector is a connecting line, the connecting line passes through a pulley; the pulley is mounted on a back cover of the casing, and is located above the motor
