Top-Mount Faucet Pressing Hook for Variable Countertop Holes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional top mounting faucets face challenges in being installed in countertop holes of varying sizes and accommodating multiple water supply lines due to the limitations of the overturning pressure ring's width and the lifting seat's tilt angle, preventing smooth insertion and fixation.
Innovation Solution
A fixture comprising a base, threaded rod, moveable block, and pressing hook with an open-style design allows the pressing hook to tilt and rotate, enabling it to fit through holes of different diameters and accommodate various water lines without increasing its volume or width, ensuring secure mounting and smooth insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the overturning pressure ring is designed with sufficient length to allow smooth insertion of multiple water supply lines, then the water supply lines can be inserted through smoothly, but the width of the overturning pressure ring increases and it cannot pass through mounting holes with smaller diameters
Solution Approach 1:
The pressing hook is designed to be tiltable and rotatable, transforming from a static structure to a dynamic one. During installation, the pressing hook tilts to a tilted position to reduce its projection width, allowing it to pass through small mounting holes. After installation, it rotates to a working position to provide sufficient space for water supply lines.
Solution Approach 2:
The pressing hook utilizes rotational movement around a pivot axis to change its spatial orientation. By rotating between a tilted position (for insertion) and a working position (for accommodating water lines), it effectively uses the angular dimension to resolve the contradiction between insertion ease and water line accommodation.
2Strength
If the lifting seat is provided with a pressing platform to reduce pressing force on the pivot shaft, then the pivot shaft experiences less stress, but the tilt angle of the overturning pressure ring is limited and it cannot pass through mounting holes with smaller diameters
Solution Approach 1:
The pressing hook's tilt angle is no longer limited by a pressing platform. Instead, the pressing force is applied through the moveable block and threaded rod mechanism, allowing the pressing hook to achieve a larger tilt angle for passing through small mounting holes while still providing adequate pressing force through the threading mechanism.
3Device complexity
If the overturning pressure ring is designed with fixed width, then the structure is simple, but it cannot adapt to mounting holes with different sizes
Solution Approach 1:
The pressing hook is designed with tiltable and rotatable capabilities, transforming it from a static fixed-width structure to a dynamic adjustable structure. This allows the same component to adapt to different mounting hole sizes by changing its orientation, maintaining structural simplicity while achieving versatility.
4Ease of operation
If the pressing hook is designed with larger volume to accommodate multiple water lines, then water lines can be inserted smoothly, but it cannot pass through mounting holes with smaller diameters
Solution Approach 1:
The pressing hook's volume requirement is resolved through dynamic reconfiguration. In the tilted position during insertion, it presents a compact profile to pass through small holes. After installation and rotation to the working position, it provides sufficient internal space and opening for accommodating multiple water supply lines without requiring increased overall volume.

AI summary
A fixture of a top mounting faucet is provided. The fixture includes a base, a threaded rod, a moveable block, and a pressing hook. The base includes a mounting hole, an insertion hole, and a first stopping rod. The threaded rod is pivotally connected to the insertion hole and a bottom of the first stopping rod and rotatable. The moveable block is threaded on the threaded with its rotation limited by the first stopping rod. The pressing hook is eccentrically arranged at the moveable block and having first and second curved portions and a connection portion connected to one another to form a mounting space with a notch. The first stopping rod and the threaded rod are inserted through the mounting space. Thereby the titled pressing hook can be inserted through an installation hole on a countertop smoothly and pressed against a bottom surface of the countertop firmly.
