Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual adjustment method is used, then device complexity is reduced, but adjustment precision deteriorates
Solution Approach 1:
The patent replaces the purely mechanical manual adjustment system with an automated system that uses an image sensor to detect the user's position and a motorized driving mechanism to automatically adjust the display angle. This substitution of mechanical manual operation with sensor-based automated control resolves the contradiction by achieving high precision adjustment without requiring complex manual manipulation mechanisms.
Solution Approach 2:
The display device performs self-adjustment by using its own image sensor to detect the user's position and automatically controlling its own display angle through the driving mechanism. This self-service capability eliminates the need for external manual intervention while maintaining simple device structure, thereby resolving the contradiction between device complexity and adjustment precision.
2Ease of operation
If manual adjustment is used, then ease of operation is improved for simple cases, but usability deteriorates for users with reduced mobility
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated sensor-based system that detects user position and automatically adjusts the display. This eliminates the need for physical manipulation, making the system equally accessible to users with reduced mobility while maintaining ease of operation for able-bodied users, thereby resolving the contradiction between ease of operation and adaptability.
Solution Approach 2:
The system performs self-adjustment based on image sensor detection, eliminating the need for user physical interaction. This self-service mechanism ensures that users with reduced mobility can benefit from automatic adjustment without requiring manual operation capabilities, thus improving adaptability while maintaining operational simplicity.
3Device complexity
If manual adjustment is used, then device complexity is reduced, but adjustment time increases
Solution Approach 1:
The patent replaces manual adjustment with an automated system using image sensors and motorized driving mechanisms. This substitution enables rapid automatic adjustment based on real-time user position detection, significantly reducing the time required for angle adjustment while keeping the overall system structure relatively simple, thus resolving the contradiction between device complexity and adjustment time.
Solution Approach 2:
The system performs preliminary detection of user position using the image sensor before execution of the adjustment action. This preliminary detection enables the system to pre-calculate the required adjustment parameters and execute the movement efficiently, reducing overall adjustment time while maintaining simple device architecture.
4Ease of operation
If the support frame is in expanded condition, then ease of operation is improved, but space occupation increases
Solution Approach 1:
The patent employs a dynamic support frame that can transition between folded and expanded configurations. The frame rotates about a vertical axis to change its spatial footprint, allowing it to occupy minimal space when folded and provide full accessibility when expanded. This dynamic adaptability resolves the contradiction between ease of operation and space occupation.
Solution Approach 2:
The support frame utilizes rotational movement about a vertical axis to change its spatial arrangement from a compact folded state to an expanded operational state. By introducing rotational freedom in the vertical dimension, the frame can achieve both compact storage and full accessibility without compromising either extreme, thus resolving the space versus accessibility contradiction.

AI summary
A display fine-adjustment device includes a display and a driving mechanism, the display being drivable by the driving mechanism to rotate; a support frame, which is connected to the display and includes supporting arms rotatably interconnected for being switchable between a folded condition and an expanded condition; and a sensor, which is electrically connected to the driving mechanism. A user manually pulls the support frame from the folded condition to the expanded condition to make the display fast approach the user and uses the sensor to detect the user and use the driving mechanism to drive the display to rotate to have the display facing the user, achieving an advantage of being time-saving and easy. In case of being not in use, folding can be made for space saving, while in use, the function of fine angle adjustment is performable to adjust the display to the most comfortable viewing angle.
