Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If high negative pressures and large air suction are achieved in known storage devices, then vacuum efficiency is improved, but device complexity and power loss increase due to complex conversion measures being required
Solution Approach 1:
The suction line is designed with pivotable connections between the storage unit and the vacuum generation device, allowing dynamic adjustment of the suction line position and angle. This dynamic design enables the storage unit to be moved horizontally and vertically without requiring complex conversion measures, while maintaining effective vacuum connection throughout the movement range
Solution Approach 2:
The invention changes the structural parameters of the suction line by replacing rigid fixed connections with pivotable joints. This parameter change allows the suction line to adapt to different positions and angles, eliminating the need for complex conversion measures when adjusting the storage unit position, thereby reducing both device complexity and power loss
2Adaptability or versatility
If the storage unit is moved horizontally and vertically or tilted in known devices, then operational flexibility is improved, but vacuum efficiency decreases due to limitations of corrugated pipes and hoses
Solution Approach 1:
The suction line incorporates pivotable connections that enable dynamic movement of the storage unit in horizontal, vertical, and tilting directions. The pivotable joints maintain sealed connections during movement, allowing full operational flexibility without compromising vacuum efficiency
Solution Approach 2:
The pivotable connection acts as an intermediary element between the storage unit and the rigid suction line. This intermediary component accommodates movement and position changes while maintaining the integrity of the vacuum seal, thus preserving vacuum efficiency during flexible operations
3Device complexity
If complex conversion measures are implemented to achieve high negative pressures, then vacuum efficiency is improved, but device complexity increases
Solution Approach 1:
The pivotable suction line design allows the system to achieve high negative pressures without complex conversions. The dynamic connections enable direct coupling between the storage unit and vacuum generation device, simplifying the overall system while maintaining effective vacuum pressure
