Leak Test Seal with Movable Plate for Selective Portion Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing leak test apparatuses require excessive thrust to seal multiple open portions on a workpiece due to the need for simultaneous sealing and the inability to selectively control the sealing of individual open portions, leading to increased energy consumption and potential for excessive load on sealing components.
Innovation Solution
A leak test apparatus featuring a plate, a movable seal, and a pressure chamber, where the seal is slidably inserted and sealed by test fluid pressure, allowing for selective sealing of open portions by adjusting the position of the seal relative to the workpiece, thereby reducing the required thrust and accommodating varying positions of open portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the driving means generates large thrust to seal multiple open portions simultaneously, then all open portions can be sealed at once, but the thrust required becomes excessively large and cannot selectively seal individual open portions
Solution Approach 1:
The sealing system is divided into multiple independent sealing units, each capable of sealing one or more open portions. Each sealing unit can be independently controlled to seal specific open portions, allowing selective sealing without requiring excessive thrust to seal all portions simultaneously.
Solution Approach 2:
The sealing units are designed to be movable relative to the workpiece, allowing dynamic adjustment of their positions. This enables the system to adapt to different configurations of open portions and selectively seal only the necessary portions with optimized thrust forces.
2Adaptability or versatility
If the driving means generates sufficient thrust to seal the farthest open portion, then all open portions can be sealed, but the thrust becomes excessive when open portions are closer together
Solution Approach 1:
By dividing the sealing function into multiple independent units, each unit only needs to generate sufficient thrust for its designated open portion(s), rather than requiring enough thrust to reach the farthest open portion regardless of their actual positions. This segments the force requirement and reduces excessive thrust.
Solution Approach 2:
Each sealing unit is optimized for sealing specific local areas where open portions are located. The thrust generation is localized to each unit's operational range, ensuring sufficient force is applied only where needed without generating excessive force for the entire sealing system.
3Ease of operation
If multiple sealing units are used to seal different open portions, then selective sealing is enabled, but the device complexity increases
Solution Approach 1:
Each sealing unit is designed as a universal module that can seal one or more open portions depending on its position and configuration. This multi-functionality reduces the need for different types of sealing mechanisms, simplifying the overall device structure while maintaining selective sealing capability.
Solution Approach 2:
Multiple sealing units are merged into a coordinated system that shares common components such as the driving mechanism and control system. This merging approach enables selective sealing of different open portions while avoiding the complexity of completely independent sealing systems.

Function Achieved in This Case
The apparatus effectively reduces the thrust needed for sealing, simplifies the structure, and extends the lifespan of sealing components by distributing the force optimally, allowing for efficient and precise sealing of multiple open portions with reduced energy consumption.
Implementation Method 1
pushing the seal with a pressure of the test fluid from the pressure chamber

AI summary
A leak test apparatus that tests for a leak in a workpiece includes a plate; a seal that is able to move relative to the plate and is supported by the plate; a driving portion that supports the plate and moves the plate; and a pressure chamber that is surrounded by the plate and the seal. The seal is formed in a shape that enables the pressure chamber to be communicated with an outside.
