Twist-Lock Faucet Mounting Nut for Fast Tightening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tightening a nut to secure a sanitary faucet to a support requires significant time and effort due to the length of the faucet shaft, often necessitating more than 20 turns.
Innovation Solution
A nut design featuring adjustable threaded lugs and a twist lock that allows for partial assembly without rotation, enabling secure fastening with fewer than five turns by locking the lugs in place after partial attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional nut is screwed onto a long faucet shaft, then the sanitary faucet can be secured to the support, but the tightening process requires considerable time and effort (more than 20 turns)
Solution Approach 1:
The nut is divided into a base body and multiple threaded lugs that can be independently adjusted. The threaded lugs can be radially adjusted outwardly to engage with the faucet shaft thread, allowing the nut to be secured without complete rotation. This segmentation enables partial engagement while maintaining securing reliability.
Solution Approach 2:
The threaded lugs are designed to be radially adjustable during the tightening process. This dynamic adjustment capability allows the lugs to move outwardly to engage the thread and then be locked in position, transforming the traditional continuous rotational tightening into a staged process that reduces turns while maintaining securing strength.
2Ease of operation
If a nut with adjustable threaded lugs is used, then the number of tightening turns is reduced, but the nut structure becomes more complex
Solution Approach 1:
The adjustment mechanism for the threaded lugs is integrated into the base body of the nut. The twist lock mechanism combines the adjustment and locking functions in a single integrated component that rotates relative to the base body, simplifying the overall structure while providing the needed functionality.
Solution Approach 2:
The threaded lugs are designed to be automatically locked in their adjusted position through the twist lock mechanism. Once the lugs are radially adjusted outwardly, rotating the twist lock automatically secures them in place without requiring additional tools or complex locking procedures, making the system self-sufficient.
3Productivity
If the threaded lugs are made adjustable in the radial direction, then the nut can be secured with fewer turns, but the locking mechanism becomes more complex
Solution Approach 1:
The twist lock acts as an intermediary mechanism between the adjustable threaded lugs and the base body. It provides a simple rotational interface that controls the radial adjustment and locking of the lugs, transforming a potentially complex multi-step locking process into a single rotational action.
Solution Approach 2:
The threaded lugs are designed with flexibility to allow radial adjustment. This flexibility enables the lugs to bend outwardly for engagement and then be locked in position, providing a simple mechanical solution that eliminates the need for complex rigid locking structures.
