Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If mechanical transmitting means (e.g., chain) are used for power transmission, then power can be transmitted continuously, but friction losses occur and mechanical parts must be moved
Solution Approach 1:
The patent replaces the mechanical chain transmission system with a fluid-based transmission system. Instead of using mechanical links that physically connect and move, the invention uses a fluid-filled pipe where pressure waves or fluid movement transmit power from the first piston to the second piston, eliminating the need for complex mechanical connecting parts and reducing friction losses.
Solution Approach 2:
The patent employs hydraulic or pneumatic principles by using a fluid (liquid or gas) as the transmitting medium. The fluid is contained in a pipe and responds to pressure changes generated by the first piston, transmitting this pressure change to the second piston to produce motion. This approach replaces solid mechanical transmission with fluid-based transmission, reducing friction and simplifying the system.
2Length of stationary object
If mechanical transmitting means are used for long-distance power transmission, then power can be transmitted, but it becomes costly or impossible
Solution Approach 1:
By replacing mechanical chain or rod transmission with a fluid-filled pipe system, the patent enables cost-effective long-distance power transmission. The pipe can be easily routed over long distances and around obstacles, and the fluid transmission mechanism remains simple and inexpensive compared to mechanical alternatives that would require increasingly complex and costly components for longer spans.
Solution Approach 2:
The transmission system is segmented into modular components: a pipe that can be laid in sections, filling stations for the fluid, and piston units that can be independently installed. This segmentation allows the system to be manufactured and installed in manageable sections, making long-distance transmission economically feasible.
3Power
If mechanical transmitting means are used, then power transmission is possible, but the transmitting elements must be moved
Solution Approach 1:
The patent eliminates the need for heavy mechanical transmitting elements by using a lightweight fluid as the power transmission medium. The fluid has negligible weight compared to mechanical chains or rods, and the pipe containing it can be supported along its length, significantly reducing the weight of moving components while maintaining power transmission capability.
4Adaptability or versatility
If a fluid is used as power transmitting element, then transmission losses are reduced and adaptability to distance is improved, but the device requires a pipe system
Solution Approach 1:
The pipe system serves multiple functions: it contains the fluid, guides the fluid movement, provides structural support, and can be routed in various configurations to adapt to different installation spaces and distances. This multi-functionality reduces the need for additional components and simplifies the overall device complexity despite the pipe system's presence.
