Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a stator is placed in the main flow of channeled water to generate electric current, then electric current generation is achieved, but fluid flow is disturbed and efficiency is limited
Solution Approach 1:
The stator is extracted from the main fluid flow path and positioned in a side chamber, allowing the main flow to remain undisturbed while still enabling electric current generation through the rotor-stator interaction in the side chamber
Solution Approach 2:
The device segments the fluid flow into a main flow path (undisturbed) and a side chamber flow path (where energy extraction occurs), allowing simultaneous high efficiency and power generation
2Power
If the rotor axis is coupled to the stator to generate electric current, then power generation is achieved, but sealing problems occur at the center of the pipe
Solution Approach 1:
The stator is extracted from the central axis location and placed in a side chamber, eliminating the need for central sealing and allowing the rotor axis to rotate freely without sealing complications
Solution Approach 2:
The side chamber acts as an intermediary space where the rotor-stator interaction occurs, separating the power generation function from the main fluid flow path and eliminating direct coupling requirements
3Power
If conventional hydroelectric technologies are used in pipes of varying sizes, then power generation is achieved, but the solutions are not suitable for small pipes such as building fluid supply pipes
Solution Approach 1:
The device design with side chamber configuration and adjustable components makes it universally applicable to pipes of various diameters, from large hydroelectric pipes to small building supply pipes, maintaining functionality across different scales
Solution Approach 2:
The device incorporates adjustable components that can be dynamically configured to match different pipe sizes and flow conditions, enabling adaptation from large-scale hydroelectric applications to small-scale building water supply systems
