Extended-Handle Ice Dam Hammer for Ground-Level Roof Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing ice dams from roofs are hazardous due to the need for workers to use ladders, making it difficult to safely break and remove packed snow and ice, especially at heights, which can lead to water damage and roofing material issues.
Innovation Solution
An ice dam hammer with an anodized aluminum breaking head and tubular aluminum adapter, designed to connect to a roof rake handle, featuring a pointed side, rounded protrusions, and flat surfaces for secure attachment, allowing safe breaking of ice dams from the ground without requiring ladder access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a worker uses a ladder to reach the roof to break ice dams, then the worker can access the ice dams to remove them, but the worker faces safety hazards and difficulty in safely reaching the roof at required depth
Solution Approach 1:
The patent uses an intermediary tool (ice dam hammer with extended handle) that allows the worker to break ice dams from the ground level. The hammer acts as a mediator between the worker and the ice dams, eliminating the need for direct contact with the roof edge while maintaining effective ice breaking capability.
Solution Approach 2:
The patent extends the operational dimension by using a long-handled hammer that reaches from ground level to the roof edge. This dimensional extension allows the worker to operate from a safe position on the ground while still accessing the ice dams at roof level.
2Productivity
If a worker stands close to the roof edge to break ice dams, then the worker can effectively break the ice, but the worker risks falling from the roof
Solution Approach 1:
The ice dam hammer serves as an intermediary tool that delivers breaking force to the ice dams without requiring the worker to position themselves in a hazardous location. The tool transmits the breaking action from a safe distance.
Solution Approach 2:
The ice dam hammer is segmented into distinct functional parts: a heavy ice-breaking head for effective ice fracture, a long handle for reaching from ground level, and a connection mechanism for secure attachment. This segmentation allows each part to fulfill its specific function while maintaining overall safety and effectiveness.
3Strength
If a heavy hammer is used to break ice dams, then the ice breaking effectiveness increases, but the hammer becomes harder to control and swing
Solution Approach 1:
The hammer is segmented into a heavy head for ice breaking and a long, manageable handle for control. This segmentation allows the mass to be concentrated in the head where it is needed for breaking force, while the handle remains lightweight and ergonomic for easy manipulation.
Solution Approach 2:
Different parts of the hammer have different quality characteristics: the head is made heavy and dense for maximum breaking force, while the handle is made lighter and longer for leverage and control. This local differentiation of properties optimizes both strength and ease of operation.

AI summary
An article of manufacture for providing an ice dam hammer is made from an ice breaking head, coupled to a tubular aluminum adapter designed to connect to the detachable handle of an existing article of manufacture known as a roof rake. The ice breaking head includes a main breaking head whereas the lower/bottom side of the ice breaking head has a plurality of blunt protrusions. The upper/top side of the ice braking head has two flat protrusions. The one side of the hammer head is pointed. The second side of the hammer head has a rounded end.
