Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pressure intensifier is designed for high forces with stable connection, then the connection stability is improved, but the device becomes massively formed and requires auxiliary devices for handling
Solution Approach 1:
The patent combines the pneumatic unit, hydraulic unit, and coupling unit into a single integrated handling unit. This merging allows the device to achieve stable high-force connection through the integrated coupling unit while maintaining compact dimensions that enable easy handling without auxiliary devices.
2Adaptability or versatility
If additional power connection is added for operation, then the functionality is improved, but the device complexity and adaptability to different voltage standards worsens
Solution Approach 1:
The patent extracts and eliminates the electrical power connection component from the pressure intensifier system. By removing the electricity requirement and designing the device to operate exclusively on gas or compressed air, the invention achieves universal adaptability to different voltage standards while reducing device complexity.
3Adaptability or versatility
If the coupling unit allows tool replacement, then the versatility is improved, but hydraulic fluid leakage occurs during tool changes
Solution Approach 1:
The patent implements preliminary action by providing a liquid outlet valve that can be closed before tool replacement. This allows the hydraulic line to be depressurized in advance, preventing hydraulic fluid leakage during tool changes while maintaining the ability to interchange tools.

AI summary
The pressure intensifier (1) has a gas or air pressure driven pneumatic unit (5) connected with a hydraulic unit (4). A coupling unit (3) immovably and releasably connects the hydraulic tool (7) with the hydraulic unit. The pneumatic unit, hydraulic unit and coupling unit are integrated into one-piece mobile handling unit (2). The coupling unit is adjusted between locked position and unlocked position, where the coupling unit is separated from the hydraulic tool in unlocked position and is fixed with the hydraulic tool in locked position.
