Wedge Clamp Assembly for Fast I-Beam Panel Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clamp assemblies for securing trailer fairings to cargo trailers are labor-intensive, require multiple bolts, and compromise the integrity of I-beams, leading to increased installation time and costs, especially when retrofitting or replacing panels.
Innovation Solution
A clamp assembly comprising a pair of inverted 'L' side blocks and a 'T' clamping block, secured to I-beams with a single bolt, allowing for rapid installation without drilling or welding, and accommodating I-beams of varying sizes and depths, using a ribbed structure and flexible materials for rigidity and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional clamp assemblies use multiple bolts and drilling to secure panels to I-beams, then the securement strength is improved, but the installation time and labor costs increase significantly
Solution Approach 1:
The clamp assembly is divided into separate components: a clamp body with wedge surfaces, a panel, and the I-beam. The segmented design allows the clamp to be positioned and secured in a single operation without requiring multiple drilling and bolting steps, thus reducing installation time while maintaining securement strength through the wedge-locking mechanism.
Solution Approach 2:
The traditional mechanical system of multiple bolts and drilled holes is replaced with a wedge-based friction and normal force system. The inclined wedge surfaces convert a single securing action into strong clamping forces through mechanical advantage, eliminating the need for multiple fasteners and drilling operations.
2Strength
If traditional clamp assemblies require drilling and welding, then the securement is improved, but the integrity of the I-beam is compromised
Solution Approach 1:
The harmful elements of drilling and welding are extracted from the securement process. The clamp assembly achieves securement through friction and normal forces generated by the wedge surfaces, eliminating the need to drill holes or weld to the I-beam, thus preserving beam integrity while maintaining securement strength.
Solution Approach 2:
The clamp body acts as an intermediary between the panel and the I-beam. Instead of directly drilling or welding to the I-beam, the clamp mediates the connection through friction-based clamping, distributing forces without compromising the structural integrity of the I-beam.
3Reliability
If traditional clamp assemblies use multiple components and fasteners, then the securement reliability is improved, but the device complexity increases
Solution Approach 1:
Multiple traditional components (multiple bolts, washers, brackets, and drilling operations) are merged into a single integrated clamp assembly with wedge surfaces. This consolidation maintains securement reliability through the mechanical advantage of the wedge system while dramatically reducing the number of discrete components and assembly steps.
4Strength
If traditional installation methods are used for trailer fairings, then the securement is robust, but the labor costs and installation complexity increase
Solution Approach 1:
The clamp assembly is pre-configured with its wedge surfaces and geometry designed to automatically generate the necessary clamping forces upon installation. This preliminary design eliminates the need for complex adjustment and multiple fastening operations during installation, making the process easier while maintaining robust securement.

AI summary
A clamp assembly is provided for securing a panel or fairing to an I-beam, and comprises a pair of side blocks and a clamping block, together with a single bolt to secure them in place. Each of the side blocks as an inclined wedge surface, and the T-shaped clamping block has similarly sloped wedge surfaces along the sides of the leg of the T. When a bolt this passed through side legs of the side blocks, and through or under the clamping block, a sliding and wedging action between the inclined and sloped wedge surfaces occurs. Moreover, a clamping action between the top surface of the clamping block and the lower surface of the lower flanges of the I-beam is also induced.
