Tile Lippage Control Cam Leveler Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tile leveling devices are inefficient, causing repetitive stress injuries, duplicative work, and require two hands to operate, leading to inconsistent spacing and increased installation time, while also potentially damaging tiles with lateral forces and requiring additional cutting steps.
Innovation Solution
A tile lippage control and spacing system featuring a spacer post with a breakaway connection and a leveler that is axially slidably and rotationally threadably engaged, allowing for one-handed operation, reducing lippage and maintaining consistent spacing without exerting lateral forces on tiles, and allowing for easy removal and reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If axial rotation tighteners are used to control tile lippage, then tile leveling is achieved, but installation time increases and installer fatigue increases due to repetitive axial rotation
Solution Approach 1:
The patent replaces the traditional axial rotation tightening mechanism with a cam-based mechanical system. The cam profile converts simple downward pressing motion into the necessary clamping action, eliminating the need for repetitive axial rotation. This substitution reduces installation time and physical fatigue while maintaining tile leveling precision.
Solution Approach 2:
The patent extracts and eliminates the axial rotation step from the tightening process. By using a cam mechanism that achieves clamping through pure downward motion, the invention removes the time-consuming rotational component while preserving the essential tile leveling function.
2Manufacturing precision
If axial rotation tighteners are used to control tile lippage, then tile leveling is achieved, but the process becomes duplicative requiring tightening and loosening rotations
Solution Approach 1:
The patent removes the loosening operation entirely by designing a disposable plastic tightener that is broken off after use. This extraction of the reversibility requirement simplifies the operation to a single downward pressing and breaking action, eliminating duplicative steps.
Solution Approach 2:
The invention employs a disposable plastic tightener that is discarded after a single use. This approach eliminates the need to loosen and reuse the device, reducing operational complexity while maintaining precise tile leveling through the cam mechanism.
3Manufacturing precision
If two-handed operation is required for tile leveling devices, then control precision is improved, but ease of operation decreases and back issues are exacerbated
Solution Approach 1:
The patent segments the tile leveling function into two independent components: the plastic tightener that provides mechanical clamping action and the separate spacing wedge that controls tile spacing. This segmentation allows each component to be operated independently with one hand, improving ease of operation while maintaining precision through the specialized function of each segment.
Solution Approach 2:
The patent introduces a separate spacing wedge as an intermediary element between the tiles. This wedge handles the spacing control function independently, allowing the main tightener to focus solely on lippage correction with one-handed operation.
4Manufacturing precision
If traditional tighteners are used, then tile lippage is controlled, but lateral forces are exerted on tiles causing joint line irregularities
Solution Approach 1:
The patent inverts the traditional approach by applying clamping force from above through the cam mechanism rather than from the sides. This upward-to-downward force application eliminates lateral forces that would otherwise push tiles apart and create irregular joint lines, while still achieving effective lippage control.
