Profiled Smoothing Ruler for Concrete Sill Slope
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for creating door or window sills in concrete or mortar are cumbersome, requiring precise arrangement of formwork boards and empirical calculations to achieve the desired slope, which is time-consuming and not easily adaptable to specific profiles, especially for prefabricated thresholds that often do not fit perfectly.
Innovation Solution
A profiling smoothing ruler with a bearing face that mimics the desired slope and profile, allowing simultaneous smoothing and template formation of the sill surface, featuring adjustable accessories and a spirit level for precise alignment, enabling the creation of specific profiles like those for accessibility or water runoff without the need for complex formwork adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional formwork boards are used to create sloped thresholds, then the threshold can be formed with proper slope, but the process requires precise arrangement and empirical calculations which is time-consuming and complex
Solution Approach 1:
The patent applies the copying principle by creating a physical template (the profiled smoothing rule) that replicates the desired threshold profile. Instead of calculating and arranging formwork boards to achieve the correct slope, the template directly copies the required geometric profile, allowing the mason to simply trace or follow the template shape to create an accurate threshold slope without complex measurements or calculations.
Solution Approach 2:
The patent implements preliminary action by pre-forming the desired threshold profile on the smoothing rule template before the actual threshold creation process. The template is prepared in advance with the correct slope and geometric characteristics, so that during construction, the mason only needs to apply the template to the fresh mortar and follow its profile, eliminating the need for on-site calculations and adjustments.
2Ease of operation
If prefabricated thresholds are used, then installation is simplified, but they often do not fit perfectly in terms of dimensions and require custom adjustments
Solution Approach 1:
The patent applies parameter changes by making the template dimensions and profile characteristics variable and adjustable. The smoothing rule template can be customized with different lengths, slopes, and geometric parameters to match specific project requirements. This allows the template to adapt to various threshold dimensions and configurations, providing both ease of use and dimensional versatility.
3Manufacturing precision
If multiple separate operations are used (formwork building, concrete pouring, formwork removal, slope creation), then each step can be performed carefully, but the overall process becomes complex and time-consuming
Solution Approach 1:
The patent applies the merging principle by combining multiple construction operations into a single integrated process. The template method allows the mason to create the threshold slope directly on the fresh mortar surface in one operation, eliminating the need for separate formwork building, concrete pouring, formwork removal, and slope creation steps. This consolidation maintains precision while significantly simplifying the overall construction process.
