Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If regenerative power is consumed by a regeneration resistor, then power management efficiency is improved, but device complexity increases due to additional components
Solution Approach 1:
The patent converts the harmful regenerative power that would otherwise be wasted into useful energy by connecting it to a regeneration resistor during specific operating conditions. This allows the system to utilize regenerative power from the electric motor to improve overall power management efficiency while maintaining consistent performance.
Solution Approach 2:
The patent implements dynamic switching between different power management modes based on the actual required power and operating conditions. The controller portion dynamically connects or disconnects the regeneration resistor from the electric motor, optimizing power utilization without requiring permanent complex circuitry in all operating states.
2Use of energy by moving object
If switch portion is added to control connection between electric motor and regeneration resistor, then power utilization is optimized, but device complexity increases
Solution Approach 1:
The switch portion enables dynamic control of the connection between the electric motor and regeneration resistor based on real-time power requirements. The controller activates the switch only when regenerative power utilization is beneficial, optimizing power utilization while avoiding unnecessary complexity in the circuit design.
Solution Approach 2:
The controller portion automatically manages the switching operation based on detected power conditions, making the system self-regulating. This reduces the need for manual intervention and simplifies the overall control architecture while achieving optimized power utilization.
3Reliability
If regenerative power is consumed, then consistent operation is maintained, but loss of energy increases due to resistive consumption
Solution Approach 1:
The regeneration resistor is connected periodically or intermittently based on operating conditions rather than continuously. The controller activates the resistor only when needed to maintain consistent operation, and disconnects it when not required, thereby maintaining reliability while minimizing energy loss through resistive consumption.
