Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional faucet installation and disassembly mechanisms require significant time and energy due to the narrow space under countertops, making quick assembly and disassembly difficult, especially when the nut must be rotated from the lower end of the bolt.
Innovation Solution
A quick assembly and disassembly mechanism featuring a nut seat with cantilever lock blocks and a slide block that allows for movement without rotating the nut seat from the bottom, using inclined guide surfaces and push surfaces to securely engage and disengage the faucet from the bolt, enabling easy installation and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional nut and bolt mechanism is used to install the faucet, then the faucet can be securely fixed to the countertop, but the installation and disassembly process requires significant time and energy due to the need to rotate the nut from the lower end of the bolt in narrow spaces
Solution Approach 1:
The nut seat is designed with movable cantilever lock blocks that can dynamically change position between locked and unlocked states. The lock blocks are spring-loaded to automatically engage with the bolt during installation, and can be easily disengaged by applying force in the opposite direction, transforming the static rotational locking mechanism into a dynamic linear engagement system that is much faster to operate in narrow spaces
Solution Approach 2:
Instead of rotating the nut seat around the bolt axis as in traditional mechanisms, the invention inverts the locking action by moving the cantilever lock blocks linearly toward and away from the bolt. This inversion of the locking motion from rotational to linear allows for much quicker operation in the constrained space under the countertop
2Productivity
If a quick assembly structure with one-way engagement is used, then installation speed is improved, but disassembly becomes difficult and time-consuming as the nut must be removed from the highest position to the distal end of the bolt in narrow spaces
Solution Approach 1:
The cantilever lock blocks are designed to be dynamically controllable in both directions. During installation, spring force automatically pushes the lock blocks into engagement with the bolt for quick one-way locking. During disassembly, applying force in the opposite direction easily releases the lock blocks, enabling quick two-way operation that overcomes the limitation of traditional one-way engagement mechanisms
Solution Approach 2:
The spring-loaded cantilever lock blocks automatically engage with the bolt during the installation process without requiring manual intervention, providing self-service quick locking. The same mechanism allows easy self-service disengagement by simply applying force in the opposite direction, eliminating the need for complex disassembly procedures
3Loss of time
If the nut seat is moved freely on the bolt without rotation, then assembly time is reduced, but the connection stability may be compromised
Solution Approach 1:
The cantilever lock blocks provide dynamic stabilization by automatically engaging with the bolt when the nut seat is moved into position. The spring force ensures consistent engagement pressure, maintaining reliable connection stability. The same mechanism allows easy release when force is applied in the opposite direction, enabling both quick assembly and stable connection
Solution Approach 2:
The spring-loaded cantilever lock blocks are pre-positioned to automatically engage with the bolt as the nut seat approaches during installation. This preliminary engagement action ensures stable connection is established before the nut seat is fully seated, maintaining reliability throughout the assembly process without requiring rotation

AI summary
A quick assembly and disassembly mechanism includes a nut seat and a slide block which is movably coupled to the nut seat. The nut seat includes at least two cantilever lock blocks therein. The inner wall of each lock block has threads thereon. The inner diameter encircled by the lock blocks matches with a bolt of a faucet. In normal state, the nut seat can be moved freely on the bolt. When the nut seat is moved to a counter top to compress the slide block, the slide block will push the lock blocks to mesh with the bolt tightly, so that the faucet can be mounted and dismounted quickly.
