Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gutter systems face challenges in achieving easy and secure assembly using a minimal number of components.
Innovation Solution
The gutter system incorporates indentations in the concave inner surface of the fitting and projections on the convex outer surface of the gutter trough, allowing for a snap-fit connection through projections engaging with grooves, with end stops ensuring secure locking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional gutter assembly methods are used, then the assembly can be secure and stable, but the assembly process becomes complex and requires multiple separate components
Solution Approach 1:
The patent combines multiple separate components into a single integrated gutter section by adding self-aligning protrusions that directly engage with corresponding grooves in the gutter fitting. This merging eliminates the need for separate alignment tools or multiple fastening components, thereby simplifying the assembly process while maintaining secure connection.
Solution Approach 2:
The gutter section incorporates self-aligning protrusions with alignment features that automatically guide the section into correct positioning during assembly. The protrusions are designed with tapered surfaces and positioning elements that self-align with the fitting grooves without requiring external alignment tools or complex procedures, enabling the component to service its own alignment function.
2Reliability
If traditional gutter assembly methods are used, then the connection can be secure, but the assembly process becomes time-consuming
Solution Approach 1:
The gutter section is pre-formed with self-aligning protrusions that include tapered surfaces and positioning features during manufacturing. These preliminary structural preparations enable the section to automatically align and engage with the fitting grooves during assembly, eliminating the need for time-consuming manual alignment procedures while ensuring secure connection through the pre-designed engagement geometry.
Solution Approach 2:
The protrusions incorporate tapered surfaces that allow dynamic adjustment during the assembly process. As the gutter section is inserted into the fitting, the tapered surfaces guide the protrusions into the grooves through a controlled movement sequence, enabling real-time self-alignment and engagement. This dynamic adaptation during assembly reduces time requirements while maintaining connection reliability.
3Device complexity
If simple gutter components are used, then the number of components is reduced, but the assembly security and tightness are compromised
Solution Approach 1:
The gutter section incorporates localized self-aligning protrusions with specific geometric features including tapered surfaces, positioning elements, and engagement surfaces designed for precise fit with the fitting grooves. These locally enhanced features concentrate the alignment and securing functions at specific points on the component, ensuring tight and secure assembly connections while keeping the overall component design simple and integrated.
