Shingle Removal Head with Vacuum Disposal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing shingles from a roof are labor-intensive, require manual operation, and lack efficient disposal mechanisms, posing safety risks and creating messes.
Innovation Solution
A remotely operated system with a shingle removal head, cutting member, and vacuum unit that lifts, cuts, and disposes of shingles, using a boom arm assembly for safe operation and a vacuum hose for efficient disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual prying devices are used to remove shingles, then the operator can physically pry shingles loose from the roof, but the operator must be on the roof which risks injury and creates a large mess requiring cleaning
Solution Approach 1:
The patent replaces manual mechanical prying operations with a powered shingle removal system that uses a motorized prying member to lift and remove shingles. This substitution eliminates the need for the operator to be on the roof, thereby removing safety risks while maintaining the shingle removal function.
Solution Approach 2:
The patent extracts the operator from the hazardous environment by using a remotely operated system. The shingle removal head is controlled from the ground, separating the operator's location from the roof surface and eliminating exposure to fall risks and mess creation.
2Object-affected harmful factors
If a bulky guide system is added to prevent falling from the roof, then operator safety is improved, but the system takes a considerable amount of time to put in place
Solution Approach 1:
The patent completely removes the need for guide systems by extracting the operator from the roof environment. The remotely operated shingle removal head performs all operations from the ground, eliminating both the safety hazard and the time-consuming guide system setup.
Solution Approach 2:
The patent replaces the mechanical guide system with a remote control system that operates the shingle removal head from the ground. This substitution eliminates the need for physical safety structures on the roof while maintaining operator protection.
3Productivity
If various prying mechanisms are used to remove shingles, then shingle removal function is achieved, but none include a mechanism for disposing the shingles removed from the roof
Solution Approach 1:
The patent merges the shingle removal function with the shingle disposal function into a single integrated system. The shingle removal head collects removed shingles and directs them through a chute to a waiting vehicle, combining two separate operations into one continuous process that eliminates mess creation.
Solution Approach 2:
The patent introduces an intermediary disposal system consisting of a chute and waiting vehicle. This intermediary mechanism receives shingles directly from the removal head and transports them away from the roof area, preventing mess creation while maintaining efficient shingle removal.
4Productivity
If hand held prying devices are used to lift shingles, then shingles can be removed from the roof, but there is no place to store the loose shingles creating a large mess
Solution Approach 1:
The patent extracts loose shingles from the work area by implementing an immediate disposal system. The shingle removal head collects shingles as they are removed and directs them through a chute to a waiting vehicle, preventing accumulation of loose shingles that would create mess.
Solution Approach 2:
The patent combines the shingle removal and shingle disposal operations into a single integrated system. The removal head includes built-in collection and discharge mechanisms that immediately transfer removed shingles to a waiting vehicle, eliminating the intermediate messy stage of loose shingles.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system enables faster, safer, and more efficient removal and disposal of shingles, reducing labor and mess, while ensuring operator safety by eliminating the need for manual roof access.
Implementation Method 1

AI summary
The invention is directed towards a system and method for removing shingles from a roof comprising a shingle removal head, a boom arm assembly, a vacuum, and a containment bin. The head includes a frame that defines a shingle disposal area and includes a prying member having a lifting surface for engaging the underside of shingles and lifting them from the roof and directing them to the shingle disposal area. The head also includes a cutting member for receiving and decreasing the size of the removed shingles for removal from the head by the vacuum into the containment bin, both of which may be carried by a transportation unit. The head may be attached to the boom arm assembly that is carried by a transportation unit so that the assembly causes the head to engage and lift shingles from a roof, allowing operation of the head frame from the ground.
