Fairing Clamp Restraint for Reverse Towing Damage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tractor-trailer fairings are prone to damage when the tractor unit is towed backwards, as they are exposed to turbulent air that can cause deformation or breakage, resulting in costly repairs.
Innovation Solution
The Fairing Saver device, which includes a fairing grip with a locking C-clamp, anchor ring, and fairing blocks, securely attaches to the fairings and uses a restraint to prevent movement and damage from turbulent air during towing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tractor unit is towed backwards, then the towing operation can be performed, but the fairings are exposed to turbulent air causing damage
Solution Approach 1:
The fairing saver device is installed on the fairings before towing begins. The C-clamp secures the fairing to the tractor unit frame in advance, creating a protective constraint that prevents turbulent air from causing damage during the backward towing operation.
Solution Approach 2:
The fairing saver acts as an intermediary device between the fairing and the turbulent air forces. By clamping the fairing to a stable structure, it mediates the harmful aerodynamic forces, transferring them to the stronger tractor unit frame rather than allowing direct damage to the fairing.
2Reliability
If the fairing is secured to prevent damage, then protection is achieved, but the device complexity increases
Solution Approach 1:
The C-clamp incorporates a spring-loaded mechanism with a release lever that allows the clamp to automatically grip the fairing when installed, without requiring additional fastening operations. The spring provides continuous clamping force, and the lever provides a simple one-handed release mechanism, making the device self-regulating and easy to operate.
Solution Approach 2:
The clamp mechanism uses a spring to dynamically adjust clamping force based on the fairing's position and shape variations. The spring constant and pre-load can be adjusted to accommodate different fairing sizes and materials, allowing the same device to reliably secure various fairing types without complex customization.

Function Achieved in This Case
The Fairing Saver effectively protects tractor-trailer fairings from damage during reverse towing by stabilizing them against air turbulence, thereby reducing repair costs and ensuring the integrity of the fairings.
Implementation Method 1
The spring may be coupled between the moveable jaw and the fixed handle and applies tension to the moveable jaw when the locking C-clamp is in the open position.
Implementation Method 2
The fairing blocks may be coupled to each end of the moveable and fixed jaws and press against opposing sides of an individual fairing when the locking C-clamp is in the closed position.

AI summary
A fairing saver is a device to protect aerodynamic fairings on a semi-truck from damage while it is being towed backwards. The device utilizes two (2) pairs of clamp style locking pliers. However, in lieu of conventional jaws, each jaw surface on the present Fairing Saver consists of a hard plastic pad, each measuring three inches (3″) by six inches (6″). These pads are backed by a steel plate which also provides a pivoting pin that attaches the pad to the pliers. These pliers are then attached to the fairing surfaces of the truck. An attachment clip, welded to each of the pliers, is then used with a ratchet strap or turnbuckle, to keep the sides of the fairing from moving about during the towing process. The locking plier nature of the device means that it can adapt to any thickness of fairing and locks in place with the ultimate in holding power.
