Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If fixed loads are provided by changing part size, then different load values can be obtained, but manufacturing and assembly errors make accurate control difficult
Solution Approach 1:
The patent implements a closed-loop control system that uses sensors to detect actual transverse load values and feeds this information back to the PLC control system. The PLC compares the detected load with the target load and automatically adjusts the motor-driven mechanism to compensate for deviations caused by manufacturing and assembly errors, thereby achieving accurate load control without increasing device complexity
Solution Approach 2:
The patent replaces traditional mechanical adjustment mechanisms (which rely on precise manufacturing and assembly) with an automated motor-driven system controlled by PLC. This substitution allows for dynamic, programmable control of transverse loads, eliminating the need for complex mechanical adjustments and improving accuracy through electronic control and feedback
2Productivity
If traditional adjustment methods are used, then transverse loads can be changed, but adjustment is high in cost and long in cycle
Solution Approach 1:
The patent transforms the static, manual adjustment process into a dynamic, automated system. The motor-driven mechanism allows for rapid, on-demand adjustment of transverse loads during testing, while the PLC control system ensures accuracy through programmable parameters and real-time monitoring, thereby improving both productivity and precision
Solution Approach 2:
The patent enables easy modification of transverse load parameters through software programming in the PLC system. Instead of physical adjustments requiring disassembly and reconfiguration, operators can simply change numerical parameters in the control system, achieving rapid reconfiguration with full precision maintained through the feedback control mechanism
