Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If traditional hydraulic equipment is used, then sufficient pressing force can be achieved, but the equipment becomes heavy and expensive with complex manufacturing
Solution Approach 1:
The hydraulic press is divided into multiple independent piston rods (first piston rod, second piston rod, etc.) that can move independently. Each piston rod has its own hydraulic chamber, allowing the system to achieve sufficient pressing force through distributed hydraulic pressure while reducing the weight and complexity of any single structural component compared to traditional monolithic hydraulic presses.
Solution Approach 2:
The patent utilizes hydraulic chambers and hydraulic pressure to generate pressing force. The first hydraulic chamber receives hydraulic pressure to drive the first piston rod, while the second hydraulic chamber receives hydraulic pressure to drive the second piston rod. This hydraulic mechanism provides sufficient pressing force with lighter structural components compared to traditional mechanical hydraulic presses.
2Strength
If traditional hydraulic equipment structure is used, then sufficient strength can be achieved, but the manufacturing process becomes complicated and production efficiency is low
Solution Approach 1:
The press structure is segmented into multiple independent piston rods and hydraulic chambers that can be manufactured separately and then assembled. The first piston rod, second piston rod, and their corresponding hydraulic chambers are independent components, simplifying the manufacturing process for each part while maintaining overall structural strength through their coordinated arrangement.
Solution Approach 2:
The multiple piston rods and hydraulic chambers serve multiple functions: they provide pressing force, support workpieces, and can operate independently or in coordination. This multi-functionality reduces the need for additional specialized components, simplifying the overall manufacturing process while maintaining structural strength.
3Force
If traditional hydraulic equipment is used, then sufficient pressing capability is achieved, but production efficiency is low
Solution Approach 1:
The hydraulic press system is divided into multiple independent piston rods that can operate simultaneously or independently. This segmentation allows for parallel processing of multiple workpieces or stages, significantly improving production efficiency while maintaining sufficient pressing capability through each individual piston rod's hydraulic chamber.
Solution Approach 2:
The multiple piston rods can be designed to operate in a continuous sequence or simultaneously, ensuring that the pressing action is continuous without idle time. While one piston rod is pressing, others can be preparing or completing their cycles, maintaining continuous useful action and improving overall production efficiency.
