Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If motor speed is reduced to minimize operating wastage, then device wastage is reduced and motor life is prolonged, but separation efficiency may deteriorate
Solution Approach 1:
The patent applies dynamics by making the motor speed adjustable rather than fixed. The control system dynamically adjusts motor speed based on actual engine operating conditions (intake air demand, engine load, RPM), allowing the oil-gas separator to operate at optimal speeds for different scenarios, thus minimizing device wastage while maintaining adequate separation efficiency
Solution Approach 2:
The patent changes the operating parameter (motor speed) based on different operating conditions. By establishing a relationship between engine operating parameters and optimal motor speed, the system adjusts speed parameters to match actual needs, reducing unnecessary high-speed operation and associated device wastage while ensuring separation efficiency remains sufficient
2Reliability
If motor speed is increased to guarantee separation efficiency, then separation performance is improved, but operating wastage and device wear increase
Solution Approach 1:
The patent applies partial action by providing just enough motor speed to achieve adequate separation efficiency rather than consistently operating at maximum speed. The control system determines the minimum necessary speed based on actual oil-gas separation demands, avoiding excessive speed operation that would increase device wear and operating wastage
3Ease of operation
If mechanical control means is used to adjust motor speed, then control is achieved, but operating wastage cannot be minimized due to lack of reference data
Solution Approach 1:
The patent implements feedback control by continuously monitoring engine operating parameters (intake air demand, engine load, RPM) and using this information to adjust motor speed. The control system receives feedback from the engine's actual state and modifies motor operation accordingly, enabling minimization of operating wastage while maintaining effective separation
Solution Approach 2:
The patent applies preliminary action by pre-establishing the relationship between engine operating conditions and optimal motor speed through experimentation and data collection. This pre-established reference data allows the control system to quickly determine appropriate speed settings without trial-and-error, reducing operating wastage from the start

AI summary
The inventio discloses a motor operation control method for an oil-gas separator to solve the problem that an existing oil-gas separator control strategy cannot minimize the operating speed under the precondition of satisfying operating requirements. The motor operation control method comprises: acquiring a plurality of groups of actual operating parameters output by a motor in a target operating state, establishing mapping relations according to the parameters, associating the mapping relations, and plotting a relation table; and acquiring a portion of operating parameters of the motor in a current operating state, searching for the mapping relations in the relation table to obtain other parameters, and adjusting corresponding parameter data with the obtained parameters as reference until the motor reaches the target operating state.
