Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing leak inspection methods for multiple inspection chambers suffer from reduced accuracy due to pressure interdependence between chambers, leading to increased inspection time and decreased efficiency.
Innovation Solution
A leak inspection device and method that employs a pre-compression process for one inspection chamber during the inspection of another, using a control device to manage compressed gas flow and pressure targets, allowing for simultaneous or sequential inspection of multiple chambers with reduced overall inspection time and improved accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple inspection chambers are inspected sequentially using a common path, then the inspection process can be completed, but the inspection accuracy decreases due to pressure changes in the common path affecting subsequent inspections
Solution Approach 1:
The patent divides the inspection system into separate inspection paths for each inspection chamber, with each path having its own independent compression mechanism. This segmentation isolates the pressure changes of each chamber, preventing interference between inspections while maintaining sequential inspection capability.
Solution Approach 2:
The patent implements a pre-compression process where each inspection chamber is compressed to the target pressure before the actual inspection begins. This preliminary action ensures that the chamber is properly pressurized and isolated, eliminating pressure-related measurement errors during the inspection phase.
2Measurement precision
If inspection chambers are compressed in sequence one after another, then each chamber can be inspected accurately, but the total inspection time increases significantly
Solution Approach 1:
The patent enables continuous inspection by overlapping the compression and inspection phases of multiple chambers. While one chamber is being inspected, another chamber can be compressed in preparation, ensuring that the inspection process continues without idle waiting time between chambers.
Solution Approach 2:
The patent implements dynamic control of compression timing and pressure levels for different chambers based on their inspection status. The system can adjust which chambers are being compressed versus inspected at any given moment, optimizing the overall inspection throughput while maintaining accuracy.

AI summary
A leak inspection device includes an inspection mechanism that executes a first inspection process for compressing the insides of a first inspection chamber and a reference chamber, and inspecting the first inspection chamber for a pressure leak based on a differential pressure therebetween, and a second inspection process for compressing the insides of a second inspection chamber and the reference chamber, and inspecting the second inspection chamber for a pressure leak based on a differential pressure therebetween, a first pre-compression valve that opens and closes a first pre-compression path, and a control device that opens, during the execution of the first inspection process, the first pre-compression valve to pre-compress the second inspection chamber, and causes, in a state where the inside of the second inspection chamber is pre-compressed, the inspection mechanism to execute the second inspection process.
