Rotating Chain Chimney Cleaning for Safe Indoor Soot Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing chimney cleaning methods are dangerous, expensive, and time-consuming, posing risks to individuals and often resulting in messy interiors or requiring costly professional services.
Innovation Solution
A chimney cleaning system comprising a support bracket, swivel arms, a gearbox, and a chain that rotates within the chimney pipe to remove soot and creosote without the need for roof-scaling, featuring a housing unit with a door for access and a chain that collects debris at the bottom for easy disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional chimney cleaning methods are used (fiberglass rod with brush), then cleaning can be performed, but the individual must scale the exterior of the home which creates safety risks
Solution Approach 1:
The patent inverts the traditional cleaning approach by cleaning the chimney from the bottom interior upward rather than from the top exterior downward. The system attaches to the chimney interior near the stove and uses a rotating chain mechanism that moves upward, allowing the operator to remain safely inside the house while the cleaning action occurs at the problematic locations.
Solution Approach 2:
The patent introduces an intermediary mechanical system (the housing unit with chain and swivel arms) that mediates between the operator and the cleaning action. The operator controls the system from inside the house through the housing unit, while the chain and brushes perform the actual cleaning contact with the chimney walls, eliminating the need for direct exposure to hazardous conditions.
2Reliability
If cleaning is performed from the bottom up within the house, then safety is improved, but the interior becomes messy
Solution Approach 1:
The patent extracts the debris collection function from the general cleaning process and isolates it in a separate containment system. The housing unit includes a collection container that captures soot and creosote as they are removed from the chimney, preventing them from dispersing into the house interior. The system separates the cleaning action from the debris release, allowing safe operation without creating indoor mess.
Solution Approach 2:
The patent uses a flexible chain mechanism that can conform to the chimney interior surfaces while being contained within the housing unit structure. The chain with attached brushes or scraping elements flexibly contacts the chimney walls to remove debris, while the housing unit contains the resulting particles, preventing them from escaping into the living space.
3Reliability
If professional chimney cleaners are hired, then effective cleaning is achieved, but the cost increases
Solution Approach 1:
The patent enables homeowners to perform chimney cleaning themselves through a user-friendly system that requires no specialized skills or equipment. The automated rotating chain mechanism and controlled operation from inside the house make the task accessible to ordinary users, eliminating the need to hire professional chimney sweeps while maintaining effective cleaning performance.
Solution Approach 2:
The patent replaces the simple manual rod-and-brush mechanical system with a more sophisticated automated mechanism featuring a rotating chain, swivel arms, and controlled motion. This enhanced mechanical system performs the cleaning action more effectively and safely, compensating for the lack of professional operator skill while reducing overall system cost through self-operation.
4Productivity
If traditional cleaning tools are used, then the process can be completed, but it is time-consuming
Solution Approach 1:
The patent implements continuous cleaning action through the rotating chain mechanism that constantly contacts and removes debris from the chimney walls as it moves upward. Unlike intermittent manual scraping, the system maintains continuous engagement with the chimney surface, significantly reducing the time required to clean the entire chimney while the automated rotation eliminates repetitive manual motions.
Solution Approach 2:
The patent uses dynamic, moving components (rotating chain, swivel arms, and motorized actuation) instead of static manual tools. The system adapts its motion to the chimney geometry and maintains optimal contact pressure through mechanical feedback, enabling faster cleaning while the controlled dynamics prevent damage to the chimney structure. The door mechanism provides dynamic access for maintenance without requiring full disassembly.

AI summary
The present disclosure provides a chimney cleaning system. The chimney cleaning system may include a support bracket configured to couple with a chimney pipe. The chimney cleaning system may include a first swivel arm and a second swivel arm. The system may further include a spring that connects to a first swivel arm. The chimney cleaning system may include a gearbox, and a shaft, which may be a horizontal shaft, coupled to the gearbox. The chimney cleaning system may further include a chain having a first end and a second end. The first end connects with the first swivel arm via the spring and the second end connects to the second swivel arm. The actuation of the shaft causes a rotation of the chain about the internal surface of the chimney pipe thereby causing the chain to clean soot, creosote, and other debris from at least a portion of the internal surface of the chimney pipe.
