Powered Trailer Side Panel Lever Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trailer side panels are cumbersome, difficult to store, and require manual handling, which can lead to injuries and encroach on usable space, while also not being easily integrated with powered operation to maintain trailer width compliance.
Innovation Solution
A powered side panel system for trailers that includes a pivoting side panel with a lever arm and actuator, controlled by a unit that can be powered by the vehicle, allowing for easy operation and linkage of multiple panels for simultaneous control, with components primarily located beneath the trailer to maintain width compliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If manual side panels are used, then the trailer can be equipped with simple side protection, but the panels encroach on usable space and are difficult to store
Solution Approach 1:
The side panel system transitions from a static 2D panel to a 3D deployable structure that can be stored in the vertical dimension (under the trailer bed) and deployed to the horizontal dimension (along the trailer side) when needed, eliminating space encroachment on the usable trailer bed area
2Strength
If heavy side panels are used for durability, then the panels provide robust protection, but they become cumbersome and difficult to store
Solution Approach 1:
The manual mechanical handling system is replaced with a powered actuation system that uses hydraulic or electric actuators to automatically deploy and secure the side panels, eliminating the need for manual lifting and positioning while maintaining panel strength and durability
Solution Approach 2:
The side panel system incorporates self-deploying mechanisms with actuators that automatically position and secure the panels without external assistance, making the heavy panels easy to operate through simple control input
3Ease of manufacture
If multiple people or machinery are used to lift side panels, then the panels can be installed, but the process becomes complex and time-consuming
Solution Approach 1:
The complex manual installation process involving multiple people or external machinery is replaced with an integrated powered actuation system that automatically deploys and secures the panels through electrical or hydraulic control, simplifying the installation process to a single operator pressing a button
4Length of stationary object
If side panels are made to fit within maximum width regulations, then the trailer can traverse public roadways, but internal bed space is consumed
Solution Approach 1:
The side panels are designed to store in the vertical dimension (under the trailer bed frame) and deploy to the horizontal dimension (along the trailer side) only when needed, allowing the trailer to maintain its maximum width compliance during transport while providing side protection during loading operations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides a safe, efficient, and space-saving solution for loading and unloading goods by eliminating manual handling hazards, allowing for easy operation and compliance with vehicle width regulations, while maximizing trailer usability.
Implementation Method 1
A lever arm extends between the side panel and an actuator. The actuator pivots the lever arm about a lever axis.
Implementation Method 2
The side panel configured to pivot about a panel axis in communication with the trailer.

AI summary
A powered side panel system is used in conjunction with a loading bed found on trailers and other flatbed vehicles. The system includes a side panel having a vertical member. The side panel is configured to pivot about a panel axis in communication with the trailer. A lever arm extends between the side panel and an actuator. The actuator pivots the lever arm about a lever axis. The lever arm contacts the vertical member and controls the rate of radial motion of the side panel about the panel axis. A control unit is configured to regulate the operation of the actuator device.
