Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If mechanical fixing is used to couple the cabin unit and loading unit, then the coupling strength is improved, but the assembly and disassembly time increases and durability decreases due to frequent operations
Solution Approach 1:
The patent replaces traditional mechanical fixing systems with an electromagnetic fixing system. A coil generates a magnetic field that magnetically attracts the loading unit to the cabin unit, eliminating the need for mechanical fasteners. This substitution maintains strong coupling while enabling rapid attachment and detachment through electrical control, significantly reducing assembly and disassembly time.
Solution Approach 2:
The patent changes the fixing mechanism from mechanical to electromagnetic by controlling the magnetic field strength through the coil. By adjusting electrical parameters (current, voltage) to the coil, the magnetic attraction force can be precisely controlled, allowing the loading unit to be firmly held during operation and easily released when needed, thus resolving the time-loss issue while maintaining coupling strength.
2Loss of time
If magnetic fixing is used to couple the cabin unit and loading unit, then the assembly and disassembly time is reduced, but the coupling strength becomes insufficient compared to mechanical fixing
Solution Approach 1:
The patent replaces traditional mechanical fixing systems with an electromagnetic fixing system. A coil generates a magnetic field that magnetically attracts the loading unit to the cabin unit, eliminating the need for mechanical fasteners. This substitution maintains strong coupling while enabling rapid attachment and detachment through electrical control, significantly reducing assembly and disassembly time.
Solution Approach 2:
The patent creates a composite fixing system combining electromagnetic attraction (coil generating magnetic field) with mechanical structural support (cabin unit and loading unit structures). This composite approach leverages both the rapid response of electromagnetic forces and the structural integrity of the vehicle components, achieving both strong coupling and fast operation.
3Strength
If mechanical fixing is used to couple the cabin unit and loading unit, then the coupling strength is improved, but the durability decreases due to frequent assembly and disassembly operations
Solution Approach 1:
The patent replaces traditional mechanical fixing systems with an electromagnetic fixing system. A coil generates a magnetic field that magnetically attracts the loading unit to the cabin unit, eliminating the need for mechanical fasteners. This substitution maintains strong coupling while enabling rapid attachment and detachment through electrical control, significantly reducing assembly and disassembly time.
Solution Approach 2:
The electromagnetic fixing system is self-actuating through electrical control. The coil can be energized or de-energized to automatically engage or disengage the loading unit without requiring manual intervention or mechanical operation. This self-service capability reduces wear on mechanical components and improves durability by eliminating repeated mechanical fastening and unfastening operations.
