Magnetic Cable Support for Rain Gutter Defrosting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rain gutter defrosting systems face issues with insecure cable support leading to detachment, cable disorganization, and blockage of gutters, which complicates cleaning and can damage the gutters.
Innovation Solution
A cable support with a magnetic attachment and locking groove is used, allowing the heating cable to be securely attached to the inner surface of the gutter, keeping the bottom clear for water flow and easy cleaning, and accommodating thermal expansion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are secured to the bottom of the gutter using screws, then the cables are firmly fixed in place, but the gutters are destroyed and start to leak
Solution Approach 1:
The patent replaces the mechanical screw-fixing system with a magnetic attachment system. The cable support includes a magnetic attachment that secures the heating cable to the inner surface of the gutter without penetrating or damaging the gutter material, thus eliminating gutter destruction while maintaining reliable cable fixation.
Solution Approach 2:
The patent introduces a cable support as an intermediary component between the heating cable and the gutter. This cable support with magnetic attachment serves as a mediator that provides secure fixation while protecting the gutter from damage, avoiding direct contact between screws and the gutter surface.
2Reliability
If cables are secured to the bottom of the gutter, then the cables are fixed in place, but rubbish collects on the cables and blocks the gutter
Solution Approach 1:
The patent moves the cable support from the bottom surface of the gutter to the inner surface (side wall) of the gutter. This dimensional change allows water and rubbish to flow freely along the bottom without accumulating around the cables, while the magnetic attachment ensures secure fixation on the vertical surface.
Solution Approach 2:
The patent positions the cable support specifically on the inner surface of the gutter rather than the bottom, creating a local differentiation in cable placement. This localized adjustment ensures that cables are securely fixed while the bottom surface remains clear for unobstructed water flow and easy cleaning.
3Reliability
If cables are secured to the bottom of the gutter, then the cables are fixed in place, but cleaning the gutter becomes difficult and disengages the cables
Solution Approach 1:
The patent relocates the cable support from the horizontal bottom surface to the vertical inner surface of the gutter. This dimensional relocation allows cleaning operations to proceed along the bottom without disturbing the cables, as the cables are now positioned on the side wall where they do not interfere with cleaning movements.
Solution Approach 2:
The patent separates the cable support function from the water flow path by positioning the cable support on the inner surface rather than the bottom. This segmentation allows independent access to the bottom for cleaning while the cables remain securely attached to the side wall, eliminating the conflict between cable fixation and cleaning operations.
4Reliability
If a cable support is installed in the gutter, then the heating cable can be supported, but the support structure becomes complex
Solution Approach 1:
The patent combines multiple functions into a single cable support component: structural support for the heating cable, magnetic attachment mechanism for secure fixation, and positioning feature for correct installation orientation. The cable support includes a magnetic attachment and a locking groove that work together as an integrated system, reducing the number of separate components needed.
Solution Approach 2:
The cable support is designed as a multi-functional component that provides mechanical support, magnetic attachment, and positioning capabilities in a single element. The support can be attached to the inner surface and accommodates the heating cable, while the locking groove ensures proper orientation, making the component versatile and reducing overall system complexity.
