Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid dispensing nipples face challenges such as laborious installation and removal, compatibility issues with pipes of different sizes, and high manufacturing costs, along with potential seal leakage due to wear and the need for complex threading or welding.
Innovation Solution
A nipple-type connecting element using an elastic ring for fixation, allowing simple and immediate attachment and detachment to pipes of varying sizes, ensuring a reliable seal without threading or welding, and utilizing a lever mechanism for easy installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nipples are fixed to pipes by screwing or welding, then reliable connection is achieved, but installation and removal become laborious and time-consuming
Solution Approach 1:
The nipple is divided into a body portion and a separate elastic ring (contrasting element). The elastic ring can be independently installed onto the pipe and then engaged with the nipple body, allowing quick attachment and detachment without threading or welding operations while maintaining reliable connection through the elastic retention mechanism
Solution Approach 2:
The elastic ring provides a dynamic, movable connection mechanism that allows the nipple to be quickly attached and detached from the pipe. The elastic properties enable the ring to deform during installation and removal, facilitating rapid operation while maintaining secure connection during use, thus reducing installation time without compromising reliability
2Reliability
If nipples are designed with threads or welding features, then secure fixation is achieved, but manufacturing complexity and costs increase
Solution Approach 1:
The fixation mechanism is segmented into the nipple body and a separate elastic ring component. This eliminates the need for complex threading or welding features on the nipple itself, simplifying its structure while providing secure fixation through the elastic ring that engages with simple external features on the nipple body
Solution Approach 2:
The elastic ring acts as an intermediary element between the nipple and the pipe. Instead of requiring complex features on the nipple for direct attachment, the elastic ring mediates the connection, providing secure fixation through its elastic retention while keeping the nipple structure simple and easy to manufacture
3Ease of operation
If elastic rings are used for fixation, then quick installation and removal are achieved, but seal reliability may be compromised
Solution Approach 1:
The elastic ring is pre-installed onto the pipe before the nipple is attached. This preliminary action ensures the ring is properly positioned and tensioned before the connection is made, creating immediate sealing contact when the nipple engages with the ring, thus maintaining seal reliability while enabling quick installation
Solution Approach 2:
The elastic ring provides beforehand cushioning by creating a compliant sealing interface between the rigid nipple and pipe components. The elastic properties allow the ring to deform and conform to surface irregularities, compensating for manufacturing tolerances and ensuring reliable sealing while facilitating easy attachment and detachment
