Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual adjustment method is used to adjust the spacing between display units, then the device complexity is low, but the manufacturing precision and reliability of spacing adjustment are insufficient, leading to image abnormalities
Solution Approach 1:
The patent employs a hydraulic adjustment device where a piston moves within a cylinder filled with hydraulic fluid. When the piston moves, it changes the volume of the hydraulic fluid, thereby adjusting the spacing between display units. The hydraulic system provides precise and stable spacing control through fluid pressure, eliminating the imprecision of manual adjustment methods while maintaining reasonable device complexity.
Solution Approach 2:
The patent incorporates a sensor that detects the actual spacing between display units and provides feedback to a control unit. The control unit compares the detected spacing with the target spacing and adjusts the piston position accordingly. This closed-loop feedback mechanism ensures high manufacturing precision in spacing adjustment while automating the process to reduce operational complexity.
2Reliability
If spacing between display units is not accurately controlled, then the ease of operation is high, but the display quality deteriorates due to squeezing or abnormal images
Solution Approach 1:
The sensor continuously monitors the spacing between display units and provides real-time feedback to the control unit. This ensures that the spacing is maintained within the optimal range, preventing squeezing or abnormal images. The automated feedback control eliminates the need for complex manual measurement and adjustment operations, improving both reliability and ease of operation.
Solution Approach 2:
The hydraulic adjustment device with feedback control operates autonomously to maintain proper spacing. The system self-regulates the piston position based on sensor input, eliminating the need for continuous manual intervention. This self-service mechanism ensures consistent display quality while simplifying the operation to merely initiating the adjustment process.
3Measurement precision
If traditional adjustment methods are used, then the device complexity is low, but the measurement precision of spacing is insufficient, causing display abnormalities
Solution Approach 1:
The sensor provides precise measurement of the spacing between display units and feeds this data to the control unit. This automated measurement system achieves high measurement precision by eliminating human error in manual measurement. The feedback loop allows the system to continuously monitor and adjust spacing, ensuring display quality without requiring complex manual measurement procedures.
Solution Approach 2:
The patent replaces manual mechanical measurement and adjustment with an automated hydraulic system controlled by electronic sensors and control units. This substitution of mechanical operations with automated systems provides superior measurement precision while the integration of components keeps the overall device complexity manageable.
