Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trailer cover systems are inefficient in preventing loose materials from being blown or scattered during transportation, as they lack adaptive power management and speed control mechanisms to optimize tarp rolling and unrolling processes.
Innovation Solution
A trailer cover system incorporating a motor-driven tarp roller with a sensor and controller that adjusts power voltage between higher speed/low torque and higher torque/low speed modes based on operational amperage, ensuring efficient tarp deployment and stowage, and automatically stops power when the tarp reaches its limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a motor-driven tarp roller with adaptive power management is used, then the speed and efficiency of tarp rolling and unrolling is enhanced, but the device complexity increases due to added sensors and controllers
Solution Approach 1:
The system dynamically adjusts the motor's power voltage based on real-time amperage feedback from the sensor. The controller switches between higher speed/low torque mode and higher torque/low speed mode adaptively, allowing the tarp roller to optimize performance during different phases of rolling and unrolling operations.
Solution Approach 2:
A sensor monitors the operational amperage of the motor and provides feedback to the controller. This closed-loop feedback system enables the controller to detect when the tarp reaches its limits and automatically stops power supply, preventing over-travel and improving operational efficiency.
2Use of energy by moving object
If power voltage is adjusted between higher speed/low torque and higher torque/low speed modes, then the operational efficiency is optimized, but the control system complexity increases
Solution Approach 1:
The system changes the electrical parameter (voltage) supplied to the motor based on operational conditions. By switching between different voltage levels, the system optimizes the balance between speed and torque during tarp rolling and unrolling, improving overall energy efficiency.
Solution Approach 2:
The power management system dynamically adjusts motor parameters in real-time based on feedback from the amperage sensor. This dynamic adaptation allows the motor to operate at optimal efficiency points throughout the tarp deployment cycle.
3Reliability
If automatic stop function is implemented when tarp reaches limits, then material loss is prevented, but the control system complexity increases
Solution Approach 1:
The sensor continuously monitors the motor's operational amperage, which changes as the tarp approaches its travel limits. When the amperage indicates the tarp has reached its limit, the controller automatically stops power supply, preventing over-travel and potential material loss without requiring complex mechanical stop mechanisms.
Solution Approach 2:
The system uses the motor's own electrical characteristics (amperage draw) as the sensing mechanism. The motor effectively senses its own operational state through the feedback sensor, eliminating the need for separate mechanical position-sensing systems.

AI summary
A system can include a motor for driving a tarp roller across a trailer for covering and uncovering the trailer with a tarp. The system can also include a power supply for powering the motor. The system can further include a sensor coupled with the motor for sensing power consumed by the motor as the motor is powered to drive the tarp roller across the trailer. A controller can be communicatively coupled with the sensor and operatively coupled to the motor and the power supply for switching an energy characteristic of the power supplied to the motor from the power supply between a first characteristic associated with a lower torque and a second characteristic associated with a higher torque by monitoring the power consumed by the motor and switching the energy characteristic when the power consumed by the motor indicates the lower torque is insufficient to drive the tarp roller.
