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, making them time-consuming and costly to install, especially when retrofitting or replacing panels.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional clamp assemblies use multiple bolts to secure panels to I-beams, then the securement strength is improved, but the installation time and labor costs increase
Solution Approach 1:
The clamp assembly is divided into separate components: a clamp body with wedge surfaces and a separate wedge element. This segmentation allows for rapid assembly where the wedge is inserted and secured with a single bolt, eliminating the need for multiple bolts while maintaining securement strength through the wedge mechanism that distributes load across the I-beam flanges.
Solution Approach 2:
The clamp assembly incorporates a dynamic wedge mechanism that converts a single bolt's linear motion into a clamping force. As the bolt tightens, it drives the wedge between the I-beam flanges, creating a progressive clamping action that secures the panel firmly without requiring multiple fastening points.
2Reliability
If drilling or welding is used to mount panels to I-beams, then the securement reliability is improved, but the integrity of the I-beams is compromised
Solution Approach 1:
The clamp assembly acts as an intermediary device between the panel and the I-beam. Instead of directly drilling or welding to the I-beam, the clamp body with wedge surfaces distributes the securing forces across the I-beam flanges through contact surfaces, eliminating the need for penetrative fastening methods that would compromise structural integrity.
Solution Approach 2:
The invention replaces the mechanical processes of drilling and welding with a friction-based clamping system. The wedge mechanism creates substantial clamping force through friction between the clamp surfaces and the I-beam flanges, providing reliable securement without any thermal or mechanical alteration to the I-beam structure.
3Adaptability or versatility
If traditional clamp assemblies use multiple components, then the securement adaptability is improved, but the device complexity increases
Solution Approach 1:
The clamp assembly is designed as a universal device that can accommodate various I-beam sizes and panel types. The adjustable wedge mechanism and contact surfaces allow the same basic clamp design to adapt to different beam dimensions, eliminating the need for multiple specialized clamp variants while maintaining securement effectiveness across applications.
Solution Approach 2:
Multiple functions are merged into a single integrated clamp body: the wedge surfaces provide both the clamping action and the adaptation to different I-beam sizes, the single bolt provides both positioning and securing functions, and the overall design combines adjustability with simplicity, reducing component quantity while maintaining versatility.
4Strength
If existing clamp assemblies require multiple bolts and components, then the securement strength is improved, but the labor costs and installation complexity increase
Solution Approach 1:
The clamp body is pre-configured with wedge surfaces and geometry designed to automatically align and distribute forces when the single bolt is tightened. This preliminary design of the clamping mechanism ensures that the full securement strength is achieved through the simple action of tightening one bolt, eliminating the need for multiple fastening operations while maintaining equivalent or superior securement strength.

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.
