Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional fixed-structure partial pressure injection tools are used, then the tool structure is simple and easy to manufacture, but the pressure adjustment range is limited and cannot adapt to various scenarios
Solution Approach 1:
The patent applies the dynamics principle by making the throttling groove structure adjustable rather than fixed. The arc-shaped inner plate can be positioned at different angles through the pull rod and adjusting knob mechanism, allowing the throttling groove cross-sectional area to be dynamically changed. This enables the same tool to adapt to different pressure adjustment requirements without changing the overall tool structure, resolving the contradiction between adaptability and structural simplicity.
2Measurement precision
If conventional partial pressure injection tools are used, then the device is simple, but real-time measurement of pressure and viscosity cannot be achieved
Solution Approach 1:
The patent applies the universality principle by integrating multiple measurement functions into a single tool. The tool simultaneously performs pressure reduction, real-time pressure measurement (via pressure sensor), and real-time viscosity measurement (via spontaneous viscometer). This multi-functional integration allows one tool to replace multiple separate devices, achieving comprehensive monitoring without proportionally increasing system complexity.
Solution Approach 2:
The patent applies the self-service principle through the spontaneous viscometer, which converts the kinetic energy of the flowing solution directly into electrical signals to drive itself without requiring external power sources. The viscometer automatically measures viscosity based on the solution's own flow characteristics, eliminating the need for complex external power and control systems while achieving accurate real-time viscosity measurement.
3Loss of energy
If fixed structural parameters are used in partial pressure tools, then manufacturing is simple, but viscosity loss occurs when adjusting pressure for different scenarios
Solution Approach 1:
The patent applies the dynamics principle to minimize viscosity loss by enabling dynamic adjustment of the throttling groove cross-sectional area. The arc-shaped inner plate can be rotated to different positions, changing the groove area to match the required pressure adjustment level. This dynamic adaptability allows optimization of the throttling effect for each specific scenario, reducing unnecessary energy dissipation and viscosity loss that would occur with fixed-structure tools.
