Pool Deck Masonry Scribe for Curved Edge Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for constructing horizontal masonry surfaces around swimming pools with curved or irregular shapes require time-consuming and imperfect hand-cutting of masonry pieces to match the pool edge, resulting in jagged and unsightly borders.
Innovation Solution
A masonry marking device with guide wheels and support wheels that maintain a constant perpendicular orientation to the pool wall, allowing a marker to draw a continuous line parallel to the wall for easy cutting of multiple masonry pieces, using a frame with adjustable components to accommodate irregular surfaces and ensure accurate marking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If hand-cutting methods are used to match masonry pieces to the pool edge outline, then each piece can be individually fitted, but the process is time-consuming and results in jagged, unsightly borders
Solution Approach 1:
The marking device performs preliminary action by scribing continuous curved guide lines on multiple masonry pieces before cutting. The guide wheels follow the pool wall contour and transfer it to continuous marked lines on the deck surface, enabling workers to cut multiple pieces simultaneously along these pre-marked lines rather than individually hand-cutting each piece to fit the curve.
Solution Approach 2:
The marking device creates copies of the pool wall's curved outline by using guide wheels that roll along the vertical wall surface. These guide wheels trace the wall's contour and transfer it to continuous curved lines on the horizontal deck surface through the marker, producing accurate replicated curves that can be followed for cutting multiple masonry pieces uniformly.
2Adaptability or versatility
If conventional masonry pieces are used around curved pools, then standard rectangular blocks can be employed, but each piece requiring individual sculpting increases complexity and reduces efficiency
Solution Approach 1:
The marking device creates copies of the pool wall's curved outline by using guide wheels that roll along the vertical wall surface. These guide wheels trace the wall's contour and transfer it to continuous curved lines on the horizontal deck surface through the marker, producing accurate replicated curves that can be followed for cutting multiple masonry pieces uniformly.
Solution Approach 2:
The marking device segments the complex curved outlining task into simpler components: guide wheels follow the vertical wall contour while the marker simultaneously traces the horizontal deck surface. This segmentation allows the complex curved path to be generated automatically through the coordinated motion of multiple simple elements rather than requiring manual sculpting of each piece.
3Measurement precision
If guide wheels follow complex curves of vertical walls, then accurate marking can be achieved, but maintaining constant perpendicular orientation of the frame becomes challenging
Solution Approach 1:
The invention extracts the orientation control function from the operator's manual manipulation and embeds it in the mechanical structure through the bubble level. The bubble level is mounted on the frame to indicate when the guide wheels are properly oriented perpendicular to the pool wall, removing the need for the operator to manually judge and maintain orientation and reducing marking errors from improper angles.

AI summary
A marking device or scribe for marking masonry pieces on a horizontal deck area surrounding a pool, sauna or similar below-ground construction. The device is designed for use during construction of deck areas to enable defining a border or margin a constant distance from a curved vertical edge. This marking facilitates subsequent cutting of the marked masonry pieces for removal and construction of a more aesthetic edge border. Device guide wheels follow curved vertical walls of the pool and guide a frame and attached marker that is supported on wheels on the deck. The marking device is biased against the masonry pieces to create a path line mark as the frame and guide wheels are manually move along the edge.
