Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a motor is used to power the hydraulic device, then the device can operate with electrical control, but the device is restricted to locations with power supply
Solution Approach 1:
The patent replaces the electrical motor system with a mechanical engine system. The engine directly drives the hydraulic pump through mechanical connection, eliminating the need for electrical power supply and enabling operation in remote locations without power infrastructure.
Solution Approach 2:
The engine-driven system is self-contained and does not require external power supply infrastructure. The system generates its own power through the engine, making it independent and adaptable to various locations including remote areas.
2Productivity
If manual operation is required to switch oil path, then the device can be controlled precisely, but the user must continuously intervene which reduces efficiency
Solution Approach 1:
The patent introduces an electromagnetic valve as an intermediary device that automatically controls the oil path switching. The valve responds to electrical signals to divert hydraulic oil to different circuits, eliminating the need for continuous manual operation while maintaining precise control over the hydraulic device.
Solution Approach 2:
The manual mechanical operation is replaced with an electromagnetic control system. The electromagnetic valve uses electrical signals to actuate the oil path switching, converting manual mechanical control into automated electromechanical control, thereby improving operational efficiency.
3Strength
If thick or hard materials are cut, then the cutting capability is achieved, but multiple manual operations are required which increases time consumption
Solution Approach 1:
The electromagnetic valve enables continuous and rapid switching of oil paths without interruption. This allows the hydraulic system to maintain continuous useful action during multi-step cutting operations, reducing the time lost between operations while maintaining the cutting capability for thick or hard materials.

AI summary
An engine-driven oil pump has an engine, a pump unit, an oil diverting device, a manual control unit, and a remote control unit. The engine is connected to the pump unit. The oil diverting device is mounted on the pump unit and selectively pumps hydraulic oil from the pump unit into the manual control unit or the remote control unit. With the engine, the engine-driven oil pump can generate power independently instead of relying on external power supply. Besides, the electromagnetic valve of the remote control unit allows the user to remotely control the oil path of the hydraulic oil, so the user is not required to stay along the engine-driven oil pump to manually switch the oil path, and therefore the engine-driven oil pump is more efficient regarding manpower.
