Pressure Dispensing Collar Segmentation for Recyclable Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing systems under pressure face challenges in facilitating the separation of the sampling device from the plug for recycling purposes, as the mounting process is often irreversible, especially when made from different materials.
Innovation Solution
A system that includes a collar slidingly mounted within the plug, with reciprocal snap-on means for sealed fixation, allowing for easy separation of the device from the plug, and a push button mechanism that helps maintain the collar's position for reliable sealing and intuitive disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device for sampling is firmly fixed on the plug through reciprocal snap-on means, then the sealing reliability is improved, but the ease of separation for recycling deteriorates
Solution Approach 1:
The invention divides the sealing system into three distinct segments: the plug, the collar, and the sampling device. The collar acts as an intermediary component that provides sealing between the plug and the sampling device body, while the sampling device can be separated from the plug by detaching the collar. This segmentation allows the sealing function to be maintained during use while enabling easy separation for recycling by simply removing the collar component.
Solution Approach 2:
The collar serves as an intermediary element between the plug and the sampling device body. It provides the sealing function through its bead that engages with the groove on the plug, while also facilitating easy separation. The collar can be easily detached from the plug by pulling the sampling device, allowing for simple disassembly and recycling without compromising the sealing reliability during normal operation.
2Strength
If the plug is made with metal and folded back over the upper zone, then the structural strength is improved, but the ease of manufacture deteriorates
Solution Approach 1:
The invention separates the structural support function from the sealing function. The plug provides structural strength and support, while the collar provides sealing. This segmentation allows the plug to be made with metal for strength without requiring complex folded-back structures, simplifying manufacturing while maintaining both strength and sealing performance.
Solution Approach 2:
The collar acts as an intermediary that provides sealing without requiring the plug to have complex folded-back structures. The radial bearing surface on the collar engages with the sealing bead, providing the necessary sealing function while keeping the plug design simple and easy to manufacture, even when made from metal materials.
