Leak Test Chamber Positioning for Variable-Size Workpieces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing leak testers require a different chamber for each workpiece size, lacking versatility and efficiency in accommodating workpieces of varying dimensions.
Innovation Solution
A chamber design with a positioning mechanism that includes a spacer plate and pushing body, allowing workpieces of different sizes to be positioned within a universal housing space by using a spacer plate and pushing body to maintain the workpiece apart from the chamber's members, and a nozzle that can be aligned with the workpiece opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the chamber is designed to correspond to the size of the workpiece, then the workpiece can be positioned accurately, but a different chamber must be prepared every time the size of the workpiece changes, reducing versatility
Solution Approach 1:
The chamber employs movable and adjustable components including a movable lid, adjustable positioning mechanism with movable positioning members, and adjustable spacer plates. These dynamic elements allow the chamber configuration to be modified to accommodate workpieces of different sizes within the same chamber, eliminating the need for multiple fixed-size chambers.
Solution Approach 2:
The chamber is designed as a universal testing chamber that can handle multiple workpiece sizes through its adjustable positioning mechanism. The positioning members can be moved to different locations, and spacer plates can be adjusted to create appropriate spacing, enabling a single chamber to serve multiple functions for different workpiece dimensions.
2Adaptability or versatility
If the positioning mechanism holds the workpiece apart from the chamber walls, then workpieces of different sizes can be positioned, but additional positioning components are required
Solution Approach 1:
The invention introduces spacer plates as intermediary elements between the workpiece and the chamber walls. These spacer plates create the necessary spacing to hold workpieces apart from the chamber walls while providing a simple and effective positioning solution. The spacers act as mediators that enable versatile positioning without requiring complex positioning mechanisms.
Solution Approach 2:
The positioning mechanism is segmented into multiple independent components including movable positioning members, adjustable spacer plates, and positioning guides. This segmentation allows each component to be independently adjusted and positioned, providing flexibility in accommodating different workpiece sizes while keeping the overall system manageable and not excessively complex.
