Gutter Forming Apparatus with Pre-Marked Hanger Spacing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gutter installation methods are inefficient and hazardous due to the difficulty in maintaining uniform hanger spacing, as installers must use measuring tools while on ladders, leading to potential mismeasurements and improper hanger placement.
Innovation Solution
A gutter forming apparatus that progressively forms gutter pieces with discrete, visible marks at predetermined intervals, allowing for controlled hanger placement without the need for separate measuring tools, using subassemblies that create impressions or gaps on the material as it is formed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If installers use measuring tapes and conventional instruments to locate hanger positions, then hanger placement can be performed, but maintaining uniform spacing between hangers becomes difficult and time-consuming
Solution Approach 1:
The patent applies preliminary action by pre-marking the gutter material at predetermined intervals during the forming process. These marks are created before installation, eliminating the need for installers to perform measurements and calculations on-site. The marks are strategically positioned to indicate exact hanger locations, ensuring uniform spacing is automatically achieved without time-consuming measurements during installation.
Solution Approach 2:
The gutter forming apparatus serves itself by automatically marking the gutter material at precise intervals during the forming process. The system uses the forming machinery's own movement and positioning to create marks without requiring separate measuring instruments or manual intervention. This self-marking capability eliminates the need for external measuring tools and reduces installation complexity.
2Ease of operation
If installers work at significant heights on ladders or scaffolds to measure and place hangers, then gutter installation can proceed, but the process becomes hazardous and awkward
Solution Approach 1:
The patent eliminates the need for installers to work at heights with measuring instruments by pre-marking the gutter material at the factory before shipment. Installers simply need to align the pre-marked gutter sections and place hangers at the indicated positions, transforming a complex hazardous task into a simple alignment operation that can be performed safely from ground level or with minimal height exposure.
Solution Approach 2:
The patent extracts the measurement and marking functions from the installation process itself and transfers them to the manufacturing process. By removing the measuring tape and marking tools from the installer's toolkit and embedding the marks during gutter fabrication, the patent eliminates the hazardous elements of working at heights with multiple tools and coordinates.
3Productivity
If installers handle multiple tools and materials simultaneously at height, then installation can be completed, but coordination becomes complex and dangerous
Solution Approach 1:
The patent extracts the measurement and calculation functions from the installation process and transfers them to the manufacturing process. By pre-marking hanger locations during gutter fabrication, the patent removes measuring tapes, calculators, and marking tools from the installer's equipment list, reducing tool coordination complexity while maintaining installation efficiency.
Solution Approach 2:
The gutter material itself serves the marking function by incorporating pre-positioned marks that indicate hanger locations. This eliminates the need for installers to coordinate multiple tools (measuring tape, pencil, calculator, hangers, fasteners) and instead requires only simple alignment and placement operations, significantly reducing coordination complexity.
