Integrated Gas Sensor in Multistage Vacuum Pump
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas-specific vacuum leak detectors are complex and costly, with separate gas sensors that are not integrated with the vacuum pump, leading to inefficiencies and increased system complexity.
Innovation Solution
A gas-specific sensor is integrated into a multistage vacuum pump, allowing it to detect gases directly within the pump, reducing system complexity and cost by eliminating the need for a separate sensor and housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate gas sensor is used outside the vacuum pump, then the gas detection function is achieved, but the system complexity and cost increase
Solution Approach 1:
The gas sensor is integrated directly into the vacuum pump housing, merging two previously separate components (vacuum pump and gas sensor) into a single unified device. This eliminates the need for separate sensor housings and connections, directly reducing system complexity while maintaining gas detection functionality.
2Reliability
If a separate gas sensor with separate housing is used, then gas detection is possible, but manufacturing cost increases
Solution Approach 1:
By integrating the gas sensor into the existing vacuum pump housing, the patent eliminates the need for separate sensor housing manufacturing, assembly, and installation processes. This reduces manufacturing steps, material requirements, and assembly costs while maintaining the gas detection capability.
3Adaptability or versatility
If multiple separate components (pump, sensor, housing) are used, then functional requirements are met, but the number of components increases
Solution Approach 1:
The vacuum pump housing is designed to serve multiple functions: it houses the vacuum pump stages, provides structural support, and integrates the gas sensor mounting and protection. This multi-functional design reduces the number of separate components needed while maintaining all required functionalities.
