Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual adjustment of pressure controller is used, then device complexity is reduced, but measurement precision and response time deteriorate
Solution Approach 1:
The patent replaces the purely manual mechanical adjustment system with an automated system that uses an electric motor to rotate the adjusting screw. This substitution maintains simplicity while dramatically improving pressure control precision and enabling remote operation, directly resolving the contradiction between device complexity and measurement precision.
Solution Approach 2:
The patent introduces an electric motor as an intermediary device between the operator and the pressure controller. This intermediary enables precise rotational control of the adjusting screw through electrical signals, achieving high measurement precision without requiring complex manual operations or increasing overall system complexity.
2Device complexity
If manual adjustment of pressure controller is used, then device complexity is reduced, but response time deteriorates
Solution Approach 1:
The patent replaces manual mechanical adjustment with an electric motor-driven system that can be remotely controlled. This allows immediate response to pressure anomalies without requiring physical presence or manual intervention, dramatically reducing response time while keeping the overall device structure relatively simple.
Solution Approach 2:
The patent enables preliminary action by allowing remote monitoring and control of pressure parameters. The system can detect pressure anomalies and initiate corrective actions before they develop into serious problems, reducing response time without adding complex manual adjustment mechanisms.
3Extent of automation
If motorized pilot with dedicated electrical supply is used, then automation capability is improved, but adaptability deteriorates
Solution Approach 1:
The patent designs the electric motor with a universal power supply capability that can accept various electrical power sources (AC, DC, different voltages). This multi-functionality allows the same motorized pilot to be adapted to different applications and power sources, maintaining high automation capability while improving electrical adaptability.
Solution Approach 2:
The patent enables parameter changes in the electrical input to the motor, allowing it to operate with different voltage levels and power types. This flexibility in electrical parameters maintains automation capability while significantly improving adaptability to various power sources.
4Ease of operation
If remote control capability is added to pressure controller, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent uses an electric motor to replace manual mechanical operation, enabling remote control through electrical signals. This substitution provides ease of operation with remote monitoring and adjustment capabilities while keeping the mechanical structure relatively simple, thus not significantly increasing overall device complexity.
