Compact Fluid Control Assembly With Internal Abnormality Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid control devices face challenges in detecting abnormalities, such as fluid leakage, in a compact configuration with densely arranged components, where external wiring for detection can lead to twisting or short circuits, and require a larger size to accommodate detection members, making them unsuitable for integration and external monitoring.
Innovation Solution
A fluid control device design incorporating an information processing module, a valve body with a flow path, an actuator body, a hollow casing with a through hole, a piston, and an introduction pipe for driving pressure, along with a sensor and information display panel, allowing for internal detection and external monitoring of abnormalities without exposing wiring, thus maintaining a compact size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external wiring is used for abnormality detection, then detection function is achieved, but wiring twisting or short circuiting occurs
Solution Approach 1:
The detection sensor is nested inside the fluid control device, specifically positioned within the casing to detect fluid leakage internally. This eliminates the need for external wiring that could twist or short circuit, while maintaining the abnormality detection function through internal sensor placement.
2Reliability
If detection members are incorporated into the fluid control device, then abnormality detection is enabled, but device size increases
Solution Approach 1:
The detection sensor is merged with the existing fluid control device structure, utilizing the internal space within the casing and actuator body. The sensor is integrated into the flow path structure, combining the detection function with the existing device components rather than adding separate external detection members.
3Productivity
If fluid control devices are densely arranged for compact configuration, then integration efficiency is improved, but abnormality detection becomes difficult
Solution Approach 1:
Each fluid control device performs self-detection of abnormalities through the integrated sensor that monitors fluid leakage internally. The device autonomously detects its own abnormality conditions without requiring external detection systems, enabling dense arrangement while maintaining detection capability.
