Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation is used for mechanical elevators, then the structure is simple, but work intensity is high and efficiency is low
Solution Approach 1:
The patent replaces manual mechanical operation with a hydraulic system. The hydraulic elevator uses a hydraulic cylinder to drive the elevator car, eliminating the need for manual cranking or mechanical leverage. This substitution of mechanical manual operation with hydraulic automation directly increases work efficiency while reducing the operational complexity burden on the user.
Solution Approach 2:
The patent employs hydraulic principles to achieve automatic elevation. The hydraulic cylinder converts hydraulic energy to mechanical motion, enabling the elevator car to move automatically without manual intervention. This hydraulic system provides automated control of elevation, significantly improving productivity while maintaining operational simplicity through fluid-based automation.
2Reliability
If manual operation is used for mechanical elevators, then the device is simple, but safety hazards exist
Solution Approach 1:
The patent replaces manual mechanical control with a hydraulic system that includes automatic control mechanisms. The hydraulic cylinder and control valve system provide automated elevation control, eliminating manual operation errors and reducing safety hazards associated with manual mechanical handling. The automated system maintains safer operation while managing complexity through standardized hydraulic components.
Solution Approach 2:
The hydraulic elevator system performs self-service through automatic control. The hydraulic cylinder automatically elevates and positions the elevator car based on control signals, eliminating the need for manual intervention in critical safety functions. This automation reduces human error and enhances safety while the system manages its own operation through integrated hydraulic control.
3Length of moving object
If the elevator operates at high altitude, then the working range is extended, but visual observation of the elevator state becomes difficult
Solution Approach 1:
The patent uses sensing structures to create informational copies of the elevator's physical state. Sensors detect the elevator car's position, movement, and operational status, converting physical state information into detectable signals. These sensing copies allow remote monitoring of the elevator's state at high altitudes without requiring direct visual observation, thus extending working height while maintaining observability.
Solution Approach 2:
The sensing structures act as intermediaries between the elevator's physical state and the operator's perception. The sensors detect elevator parameters and transmit this information back to the control system or operator, serving as an informational bridge that enables remote monitoring. This intermediary sensing system allows the operator to observe elevator state at high altitudes indirectly through detected signals rather than direct visual contact.
4Productivity
If automatic operation is implemented, then work efficiency increases, but device complexity increases
Solution Approach 1:
The patent uses a hydraulic cylinder as the core actuator to achieve automatic elevation. The hydraulic system provides smooth, controlled motion through fluid pressure regulation, enabling automated operation with relatively simple control mechanisms. This hydraulic approach achieves automation efficiency while keeping the system complexity manageable through the use of well-established hydraulic components and fluid-based control.
Solution Approach 2:
The hydraulic elevator system is designed to be self-service through automated control. The hydraulic cylinder automatically performs the elevation function based on control signals, eliminating the need for complex mechanical transmission systems or multiple actuators. This self-service automation achieves high work efficiency while minimizing added complexity by using a single hydraulic actuator to perform the entire elevation function.
