Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building surface panels face challenges in achieving strength and uniformity, particularly in preventing buckling and requiring additional materials and complex manufacturing processes.
Innovation Solution
A hollow building surface panel design featuring a front wall and rear wall with an interior space, a fastening strip for attachment to a support structure, an overhang for overlapping with neighboring panels, and engagement surfaces for secure interlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single layer of material is bent and folded to form siding panels, then the manufacturing process is simple, but the panel is vulnerable to buckling and lacks structural strength
Solution Approach 1:
The panel is divided into a front layer and a support layer that are separately formed and then interconnected. The support layer includes recesses that receive protrusions from the front layer, creating a segmented structure that provides buckling resistance while maintaining manufacturing simplicity through modular construction
Solution Approach 2:
The front layer is nested within the support layer structure, with protrusions from the front layer fitting into recesses in the support layer. This nested configuration allows the thinner front layer to benefit from the structural support of the backing layer without requiring the front layer to be thick or rigid
2Strength
If a foam support layer is added behind the front layer to prevent buckling, then the panel strength is improved, but the manufacturing complexity and material requirements increase
Solution Approach 1:
Instead of using foam material, the patent uses a rigid support layer with a copied geometric pattern of recesses that mirrors the protrusions on the front layer. This copied structure provides the necessary support without requiring foam materials or complex adhesive bonding processes
Solution Approach 2:
The support layer is merged with the front layer through mechanical interconnection of protrusions and recesses, creating a unified structural system. This merging eliminates the need for separate foam layers and adhesives, reducing manufacturing complexity while maintaining buckling resistance
3Stability of the object's composition
If engagement surfaces are added to interconnect adjacent panels, then the structural integrity is improved, but the panel design complexity increases
Solution Approach 1:
The engagement surfaces are integrated into the existing panel geometry, allowing the same panel structure to serve both as the visible front surface and as the interconnection mechanism. The protrusions and recesses that provide structural support also function as the engagement surfaces for connecting adjacent panels, eliminating the need for separate interconnection components

AI summary
The present disclosure relates generally to building surface panels, for example, suitable for covering a support structure of a building. The present disclosure relates more particularly to a building surface panel including a hollow panel body, a fastening strip attached to the panel body, and an overhang attached to the panel body and extending along the lower side of the building surface panel. The building surface panel includes a rear-facing engagement surface disposed at the upper side of the building surface panel and a front-facing engagement surface disposed at the lower side of the building surface panel. The front facing engagement surface is configured to engage a rear facing engagement surface of a lower neighboring building surface panel.
