Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the lubricating oil output connections and pump unit are arranged on the same side of the base support, then the device structure is simpler, but the channel guidance for lubricating oil becomes more complex and less efficient
Solution Approach 1:
The patent applies dimensional rearrangement by positioning the pump unit and output connections on opposite sides of the base support, transforming the spatial layout from a planar arrangement to a three-dimensional configuration. This allows the lubricating oil channels to follow a more direct path through the base support, reducing channel complexity while improving oil delivery efficiency to match diesel engine piston cycles.
2Volume of moving object
If the control unit is arranged on the same side as the pump unit, then the device occupies less space, but the overall compactness and optimal fluid channeling are compromised
Solution Approach 1:
The control unit is positioned on the side of the base support opposite to the pump unit, utilizing vertical and lateral spatial dimensions to achieve optimal arrangement. This dimensional distribution allows for compact overall device volume while enabling efficient fluid channeling and precise lubricating oil delivery synchronized with diesel engine piston cycles.
3Ease of operation
If the piston system uses restoring springs, then the reciprocating movement is maintained, but the dynamic delivery precision adapted to diesel engine piston cycle is reduced
Solution Approach 1:
The patent removes the restoring spring component from the piston system, extracting the element that limited precision. By eliminating the spring, the system achieves direct hydraulic control of the piston reciprocating movement through hydraulic pressure, enabling delivery precision that accurately matches the diesel engine piston cycle while maintaining ease of operation through hydraulic actuation.
