Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional top mounting faucet assemblies for kitchen basins face issues with secure fixation and easy removal, as they often require complex components and loose fastening over time, leading to insecure attachment.
Innovation Solution
A top mounting faucet assembly comprising a fixer with a base and clamper, featuring anti-rotation portions and a locking bolt system that securely attaches to the kitchen basin through a combination of toothed racks and slots, ensuring easy installation and quick removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional top mounting faucet uses a simple fastening structure, then the installation is easy, but the faucet becomes loose after a period of use and is not fixed securely
Solution Approach 1:
The faucet assembly incorporates a dynamic locking mechanism where the locking protrusion on the fixing structure can rotate or move to engage with the locking recess on the basin. This dynamic element transforms a simple static fastening into an active locking system that maintains security over time while remaining easy to install through a single rotational motion.
Solution Approach 2:
The patent introduces an intermediary locking mechanism consisting of the locking protrusion and locking recess that acts as a mediator between the faucet body and the basin. This intermediary element ensures secure fixation by creating a positive mechanical lock, preventing the faucet from becoming loose while maintaining ease of installation through a straightforward engagement process.
2Reliability
If a complex fastening structure with multiple components is used, then the faucet is fixed securely, but the installation becomes time-consuming and difficult
Solution Approach 1:
The patent merges multiple fastening functions into a single integrated fixing structure that combines the mounting base, locking mechanism, and anti-rotation features into one unified component. This consolidation maintains secure fixation through the locking protrusion and recess while simplifying installation to a single operation, eliminating the need for multiple separate fastening steps.
Solution Approach 2:
The fixing structure is designed with multi-functionality, serving as both the mounting base and the locking mechanism simultaneously. The locking protrusion integrated into the fixing structure performs the security function while the overall structure provides mounting and alignment functions, reducing the number of separate components needed and simplifying the installation process.
3Ease of operation
If the faucet body is allowed to rotate during installation, then alignment is easier, but the faucet cannot be properly secured and may rotate during use
Solution Approach 1:
The anti-rotation mechanism employs a dynamic toothed rack and pinion system where the toothed rack on the faucet body engages with the pinion on the fixing structure. This allows controlled rotation during alignment while providing automatic anti-rotation security once installed, as the meshed teeth prevent any rotational movement during use.
Solution Approach 2:
The toothed rack and pinion engagement acts as an intermediary mechanism between the faucet body and the fixing structure, providing both alignment assistance through controlled rotation and secure anti-rotation through meshed teeth engagement. This intermediary system resolves the contradiction by allowing rotation only when needed for alignment while preventing rotation during operation.
4Ease of operation
If the faucet is designed for easy removal, then maintenance is simpler, but the faucet may become loose during normal use
Solution Approach 1:
The locking mechanism is designed with dynamic reversibility, allowing the locking protrusion to easily transition between engaged and disengaged states. A single rotational motion engages the locking protrusion with the locking recess for secure fixation, while the same simple motion in reverse allows easy removal for maintenance, preventing loosening during normal use while enabling straightforward removal when needed.

AI summary
A top mounting faucet assembly is mounted on a kitchen basin having an opening and contains: a fixer, a body, and a locking bolt. The fixer includes a base and a clamper, wherein the base includes a support portion and an insertion portion, and the support portion includes a peripheral fence and a shoulder, the peripheral fence has a recessed portion and a first anti-rotation portion, the shoulder has two longitudinal holes, and the insertion portion has a cylindrical fence and two columns. The clamper contains two screw rods and two locking protrusions. The body includes a second anti-rotation portion and a threaded orifice. The locking bolt screws with the threaded orifice of the body and abuts against the recessed portion of the base so that the body is stopped and does not move along the base, hence the body does not upwardly remove from the base.
