Endwall Overhang Support via Inverted Roof Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The construction of endwall overhangs for buildings is challenging due to the need for reinforcing structures that can be cumbersome and expensive, often requiring builders to work in uncomfortable positions and making it difficult to use standard-size building materials.
Innovation Solution
A building design and method that includes a wall and roof frame with a support member and an overhang assembly comprising a roof piece, trim pieces, and a lengthwise member, where the roof piece is coupled with the support member's top surface, allowing for efficient and aesthetically pleasing endwall overhangs that match the silhouette of the eave.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If reinforcing structure is added underneath the overhang, then structural strength is improved, but builder comfort and construction efficiency deteriorate due to working from elevated positions
Solution Approach 1:
Instead of placing the reinforcing structure underneath the overhang (conventional approach), the patent inverts the approach by extending the roof frame members beyond the wall to directly support the overhang from above. This eliminates the need for builders to work from elevated positions underneath, while still providing the necessary structural strength.
2Strength
If reinforcing structure is added underneath the overhang, then structural strength is improved, but construction cost and time increase
Solution Approach 1:
The patent inverts the conventional approach by extending roof frame members beyond the wall to support the overhang from above, eliminating the need for separate reinforcing structures underneath. This reduces material costs and construction time while maintaining structural strength.
Solution Approach 2:
The roof frame members serve multiple functions: they provide the primary roof structure, extend beyond the wall to directly support the overhang, and eliminate the need for separate reinforcing structures. This multi-functionality reduces overall construction cost and time.
3Length of moving object
If roof is made longer to create overhang, then overhang function is achieved, but difficulty in using standard-size building materials increases
Solution Approach 1:
The patent divides the overhang into modular sections that can be constructed using standard-size building materials. The roof frame members extend in standardized increments beyond the wall, allowing the use of conventional material sizes while achieving the desired overhang length.

AI summary
A method of making an endwall overhang for a structure is provided. The method may include providing a roof piece, a first trim piece, and a lengthwise member. The method may also include forming an overhang assembly by coupling the roof piece with a first surface of the lengthwise member and coupling the first trim piece with a second surface of the lengthwise member. The method may further include providing a structure and coupling a support member with the outside surface of an endwall of the structure, with the support member protruding from the endwall. The method may thereafter include coupling the overhang assembly to the structure by coupling the roof piece of the overhang assembly with a top support surface of the support member.
