Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex control system with multiple valves is used to manage water pumping and drainage, then water purification functionality is achieved, but system reliability decreases due to increased risk of leaks and mechanical failures
Solution Approach 1:
The patent combines multiple control functions into a single integrated control valve that manages both water pumping and drainage operations. This merging of functions reduces the number of separate components and connection points, thereby decreasing the risk of leaks and mechanical failures while maintaining full purification functionality.
Solution Approach 2:
The control valve is designed as a multi-functional device that can perform both pumping control and drainage control through different operational modes. This universal design eliminates the need for separate specialized valves, reducing system complexity and improving reliability through fewer potential failure points.
2Strength
If traditional elastic materials are used for the storage chamber, then flexibility is achieved, but brittleness increases under cyclic loading conditions
Solution Approach 1:
The patent applies specific parameter changes to the thermoplastic elastomer material, including biaxial orientation during manufacturing and controlled cooling rates. These parameter modifications transform the material's molecular structure to eliminate brittleness while maintaining elasticity, enabling the chamber to withstand cyclic loading without failure.
Solution Approach 2:
The patent uses a composite approach by combining thermoplastic elastomer with specific additives and processing techniques to create a material that exhibits both high elasticity and high strength. The biaxially oriented structure creates a composite-like internal architecture that resists cyclic deformation while remaining manufacturable.
3Reliability
If connection points for control valves are increased to enable direct connection to storage tank, then control precision is improved, but the number of sealing points increases leading to higher leak risk
Solution Approach 1:
The patent merges multiple control connections into a single integrated control valve assembly that interfaces with the storage tank through one primary connection point. This consolidation maintains full control capability while minimizing the number of sealing interfaces, thereby reducing leak risk without sacrificing operational control.
4Object-affected harmful factors
If stagnant zones are present in the storage system for hydraulic pressure transfer, then pressure distribution is achieved, but water quality deteriorates due to bacterial and germ development
Solution Approach 1:
The patent extracts and eliminates stagnant zones from the storage system design by implementing a configuration where all water regions are in constant circulation or pressure-driven flow. This removal of dead zones prevents bacterial growth while maintaining hydraulic pressure transfer through active water movement rather than static pressure distribution.
