Rotary-Handle Tile Leveling for Even Pressure and Faster Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tile leveling devices often cause uneven pressure on tiles, leading to breakage, rotation, and require manual screwing operations, which can result in aesthetic defects and increased installation time.
Innovation Solution
A leveling device with a tie rod and rotary pressure element that applies uniform pressure through a single rotation of a handle, preventing tile breakage and rotation, and eliminates the need for screwing, featuring a T-profile stem and a spiral-shaped mechanism for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a knob is screwed onto a threaded stem to apply pressure to tiles, then the tiles can be leveled, but the pressure is uneven causing tile breakage or failure to level
Solution Approach 1:
The patent replaces the traditional screwing mechanism with a rotary pressure element that rotates around the tie rod. This substitution eliminates the uneven pressure distribution caused by threaded engagement while maintaining the ability to apply controlled pressure for leveling tiles.
Solution Approach 2:
The rotary pressure element introduces dynamic motion (rotation) to apply pressure uniformly. As the element rotates, it maintains constant contact with the tiles, ensuring even pressure distribution throughout the leveling process, unlike the static and incremental pressure of screwing.
2Manufacturing precision
If manual screwing operations are performed repeatedly, then tiles can be leveled, but installation time increases and aesthetic defects occur
Solution Approach 1:
The rotary pressure element is pre-configured to engage with the tie rod and apply pressure in a single rotational motion. This preliminary design eliminates the need for repeated manual screwing operations, achieving tile leveling in one action and significantly improving installation speed.
Solution Approach 2:
The invention skips the repetitive screwing process by using a rotary mechanism that achieves the same leveling effect in a single continuous motion. This rushes through the leveling operation, reducing installation time and minimizing the risk of aesthetic defects from multiple interventions.
3Force
If continuous screwing is performed to level tiles, then pressure can be applied, but the tie rod may break due to excessive force
Solution Approach 1:
The rotary pressure element distributes the application of force through rotational motion, preventing concentration of stress at a single point on the tie rod. This dynamic application of pressure reduces the risk of tie rod breakage while still achieving the necessary leveling force.
Solution Approach 2:
Replacing the screwing mechanism with a rotary system changes how force is transmitted to the tiles. The rotation allows force to be applied more evenly and controllably, reducing peak stresses on the tie rod that could lead to failure.

AI summary
It is described a leveling device for the correct installation of at least two adjacent flat cladding elements, said device comprising a tie rod configured to be interposed between two successive tiles and comprising a rotary pressure element configured to be removably connected to said tie rod following a rotation impressed on a handle, by means of which rotation the handle hooks the tie rod and locks it on the upper surface of the tile.
