Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional equipment or structural modifications are used for snow removal, then snow removal capability is improved, but device complexity increases
Solution Approach 1:
The drive motor is made to perform dual functions: normal vehicle propulsion and snow removal through small reverse rotations. By controlling the drive motor to rotate in small reverse increments, the vehicle body vibrates to dislodge snow without requiring separate snow removal equipment.
Solution Approach 2:
The vehicle uses its own drive motor and generated heat for snow removal, eliminating the need for external equipment. The drive motor's rotational movements create vibrations that shake off snow, and the motor's heat melts accumulated snow, making the system self-sufficient.
2Reliability
If additional equipment or structural modifications are used for snow removal, then snow removal capability is improved, but ease of manufacture deteriorates
Solution Approach 1:
The drive motor is made to perform dual functions: normal vehicle propulsion and snow removal through small reverse rotations. By controlling the drive motor to rotate in small reverse increments, the vehicle body vibrates to dislodge snow without requiring separate snow removal equipment.
Solution Approach 2:

3Reliability
If the drive motor repeats small reverse rotations to remove snow, then snow removal capability is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous motor operation, the drive motor performs partial actions by rotating in small increments and pausing. This intermittent operation reduces overall energy consumption while still generating sufficient vibrations to remove snow effectively.
Solution Approach 2:
The drive motor operates periodically by repeating small reverse rotations with pauses in between. This periodic operation creates vibrations that accumulate to dislodge snow while minimizing energy consumption compared to continuous operation.
4Reliability
If the drive motor repeats small reverse rotations to remove snow, then snow removal capability is improved, but time consumption increases
Solution Approach 1:
The drive motor operates periodically by repeating small reverse rotations with pauses in between. This periodic operation creates vibrations that accumulate to dislodge snow while minimizing energy consumption compared to continuous operation.
Solution Approach 2:
The snow removal process can be continued by repeatedly executing the small reverse rotation sequence until snow is fully removed. The system maintains readiness to continue operation without requiring repositioning or setup, ensuring continuous useful action until the snow removal objective is achieved.

AI summary
A drive motor control system performs control of a drive motor of a vehicle that includes the drive motor and a battery. The drive motor control system includes a control processor that controls an electric current supply from the battery to the drive motor and includes an operational state determiner that determines whether a condition that the vehicle is being stopped, a condition that a parking brake is being released, and a condition that a parking range is being selected are satisfied. When the operational state determiner determines that all the conditions are satisfied upon a reception of a trigger signal instructing a start of the control of the drive motor, the control processor performs control of an inverter such that the electric current supply is performed to cause the drive motor to repeat small reverse rotations and thereby induce small movements of the vehicle in front and rear directions.
