Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If control buttons are supported directly by the motor, then the control structure is simple, but the control accessibility deteriorates when the motor is positioned in hard-to-reach areas
Solution Approach 1:
A wireless remote control unit is introduced as an intermediary device between the user and the motor control system. The remote control transmits control signals wirelessly to the inverter, enabling operation without direct physical access to the motor control panel. This resolves the contradiction by maintaining simple control architecture while dramatically improving accessibility when the motor is positioned in hard-to-reach areas.
2Ease of operation
If a remote control panel connected by electrical cables is used, then the control accessibility is improved, but the mobility deteriorates when the motor needs to be moved
Solution Approach 1:
The patent replaces the mechanical connection (electrical cables connecting the remote control panel to the inverter) with a wireless communication system. The remote control uses wireless transmission to send control signals to the inverter, eliminating the need for physical cable connections. This enables the motor to be moved freely without being constrained by cable routing, thereby improving mobility while maintaining control accessibility.
3Ease of operation
If a wireless remote control is used, then the mobility and control accessibility are improved, but the device complexity increases
Solution Approach 1:
The inverter is designed to accept multiple types of control inputs: it can process signals from direct control buttons mounted on the motor, wired remote control panels, and wireless remote controls. This multi-functionality allows the system to accommodate different control methods without requiring separate dedicated systems for each, thereby limiting the increase in device complexity while still providing the benefits of wireless control.
