Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional AC motor control methods are used, then the motor can operate at fixed speed, but the rotational speed cannot be changed easily and requires internal wire reconnections
Solution Approach 1:
The patent replaces the mechanical/electrical method of changing internal wire connections with an electronic control system using an inverter. The inverter uses PWM (Pulse Width Modulation) technology to control motor speed by varying the frequency and voltage of the power supply, eliminating the need to physically rewire the motor for different speeds.
Solution Approach 2:
The patent changes the operating parameters of the AC motor by using an inverter to vary the frequency and voltage of the power supply. This allows continuous adjustment of rotational speed from 0 to maximum speed without any physical modifications to the motor, simply by changing electrical parameters through digital control.
2Adaptability or versatility
If the inverter is redesigned for different power supply modes, then the inverter can adapt to different powers, but the device complexity increases
Solution Approach 1:
The patent designs the inverter with universal adaptability to handle multiple power supply modes including single-phase input/three-phase output, single-phase input/single-phase output, and other input/output modes. This multi-functional design allows the same inverter unit to serve different applications without requiring separate designs for each power configuration.
Solution Approach 2:
The inverter incorporates dynamic switching capabilities that allow it to automatically adapt to different power supply configurations through programmable control. The internal circuitry can dynamically reconfigure its operation based on the detected power input type, providing versatility without requiring physical redesign for each mode.
3Ease of operation
If remote control functionality is added, then the control convenience is improved, but the device complexity increases
Solution Approach 1:
The patent introduces a wireless communication module as an intermediary between the user and the inverter control system. This module enables remote control through portable devices using application software, allowing users to control motor speed and monitor operations from a distance without adding complex physical control interfaces to the inverter itself.
Solution Approach 2:
The patent creates a virtual copy of the control interface on portable devices through application software. This software interface replicates the control functions, allowing users to interact with the inverter remotely as if they were directly at the device, thereby improving ease of operation without significantly increasing the physical complexity of the inverter hardware.
