Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fluid adjusting devices in valve units cannot precisely control the volume and speed of fluid, failing to meet user requirements, as they are not designed to stop fluid flow and are inefficient in pressure reduction.
Innovation Solution
A fluid adjusting device comprising three retractable cylindrical parts with strategically placed holes and grooves, allowing for adjustable expansion and retraction to regulate fluid pressure and speed, featuring curved grooves and round holes to minimize turbulence, enabling precise control of fluid volume and pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional fluid adjusting device with holes is used to reduce fluid pressure and speed, then fluid pressure and speed are reduced, but the device cannot precisely control fluid volume and speed
Solution Approach 1:
The fluid adjusting device is divided into three separate cylindrical parts, each with multiple holes. By independently controlling the extension and retraction of each part, the device can precisely adjust fluid volume and speed. Each part acts as an independent control unit with multiple holes for fluid passage, enabling granular control over fluid flow characteristics.
Solution Approach 2:
The device employs dynamically adjustable cylindrical parts that can extend and retract along the central axis. This dynamic configuration allows the device to adapt to different fluid control requirements by changing the number of active hole sets exposed to fluid flow, thereby achieving precise control over fluid volume and speed according to actual needs.
2Adaptability or versatility
If the fluid adjusting device is designed with multiple holes to reduce pressure and speed, then pressure and speed are reduced, but the device cannot stop fluid flow
Solution Approach 1:
The cylindrical parts can be fully retracted into the housing, dynamically changing the device from an open-flow configuration to a closed configuration. When fully retracted, the parts block the fluid passage completely, enabling the device to stop fluid flow. This dynamic positioning capability provides both flow reduction and flow stopping functions.
3Measurement precision
If the fluid adjusting device is expanded to provide precise control, then control precision is improved, but the device occupies more space
Solution Approach 1:
The three cylindrical parts are designed to nest within each other when retracted, with each part having a smaller diameter than the previous one. This nested configuration minimizes the device volume when not in use, allowing installation in space-constrained environments while maintaining the capability for precise fluid control when extended.

AI summary
A fluid adjusting device is installed in a valve unit so as to control the volume or pressure of the fluid passing through the valve unit. The fluid adjusting device includes three parts retractably connected to each other and holes are defined through each of the three parts. By expanding or retracting the three parts, the holes can be exposed or hidden to adjust the volume or pressure of the fluid passing through the valve unit.
