Composite Building Panel Reinforcing Stud Lip Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing structural insulated panels lack sufficient strength to withstand natural disasters while often being heavy and expensive due to excessive metal usage, necessitating a building panel with high load-bearing capabilities using less expensive materials and reduced weight.
Innovation Solution
A composite building panel design featuring a cold rolled steel frame and reinforcing studs with a U-shaped cross-section, including lips on the flanges, which increases load-bearing capacity without increasing material weight or cost, and optionally includes insulation and resistant coatings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If existing structural insulated panels use traditional reinforcing members (thin strips, wire mesh, steel studs), then the panel strength is improved, but the panel becomes heavy and expensive
Solution Approach 1:
The patent changes the geometric parameters of the reinforcing stud by adding lips to the flanges. This modification increases the load-bearing capacity and strength of the stud without changing the material type or significantly increasing the steel content, thereby improving strength without proportionally increasing weight
Solution Approach 2:
The patent creates a composite structure by integrating the lips into the stud geometry, forming a unified shape that combines the functions of reinforcement and connection. This composite geometric structure achieves higher strength-to-weight ratio compared to traditional separate reinforcing elements
2Strength
If existing structural insulated panels use traditional reinforcing members (thin strips, wire mesh, steel studs), then the panel strength is improved, but the material cost increases
Solution Approach 1:
By modifying the stud geometry to include lips, the patent achieves higher strength with the same or reduced material quantity. The lips increase the effective load-bearing area and connection strength without requiring additional steel studs or reinforcing elements
Solution Approach 2:
The stud is segmented into functional zones: the base for attachment, the flanges for lateral support, and the lips for enhanced connection. This segmentation allows each part to contribute efficiently to the overall strength, reducing the need for excessive material
3Strength
If the reinforcing stud has lips on the flanges, then the load-bearing capacity is increased, but the manufacturing complexity increases
Solution Approach 1:
The lips are created by modifying the geometric parameters of the stud during cold-formed steel fabrication. This is achieved through standard forming processes that bend the flange edges, adding complexity to the shape but not to the manufacturing process itself
Solution Approach 2:
The patent replaces complex assembly systems with an integrated monolithic stud structure. The lips are formed as part of the stud itself during manufacturing, eliminating the need for separate attachment components or complex assembly procedures

AI summary
Composite building panels and a method for manufacturing a composite building panel are disclosed. A preferred embodiment of a composite building panel comprises a cold rolled steel frame and at least one reinforcing stud. The stud of the preferred embodiment is located within the space defined by the frame and coupled to the frame at the stud's base. The exemplary stud comprises two flanges extending from the base. The flanges of the preferred stud each have a lip at an end distal to the base bent toward each other. Experiments show that the lips on the flanges of the reinforcing studs significantly increase the structural strength of a composite building panel. An alternate preferred embodiment of another composite building panel comprises two boards and at least one reinforcing stud. The exemplary boards face opposite directions, are coupled to each other, and form a space between the two boards.
