Refrigerated Trailer Height Adjustment for Ground-Level Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing utility trailers require auxiliary ramps or significant manual labor for loading and unloading cargo, which is cumbersome and time-consuming, especially for refrigerated trailers transporting perishable goods.
Innovation Solution
A ground-loading refrigerated trailer with a height adjustment system and track system that allows the trailer to lower to ground level for easy loading and unloading, eliminating the need for auxiliary equipment and excessive manual effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional utility trailer is used, then the trailer structure is simple and stable, but auxiliary ramps and additional equipment are required for loading and unloading cargo
Solution Approach 1:
The insulated enclosure is made dynamically adjustable in height relative to the frame, transitioning between a first height for transport and a second height substantially at ground level for loading operations. This dynamic adjustment eliminates the need for auxiliary ramps while maintaining structural integrity.
Solution Approach 2:
The height adjustment system serves multiple functions: it enables ground-level loading without auxiliary equipment, maintains transport stability at elevated positions, and provides a unified platform that combines the functions of traditional trailers with ground-loading capabilities.
2Ease of operation
If auxiliary ramps are used for loading, then loading can be facilitated, but the equipment becomes cumbersome to transport and takes up unnecessary space
Solution Approach 1:
The loading function previously requiring separate auxiliary ramps is merged into the trailer structure itself through the height adjustment system. The insulated enclosure becomes both the cargo container and the loading platform, eliminating the need for separate ramp equipment.
Solution Approach 2:
The auxiliary ramps and additional loading equipment are extracted from the system entirely. The ground-loading capability is achieved through the height adjustment mechanism integrated into the trailer, removing the need for external loading aids that consume transport space.
3Stability of the object's composition
If the trailer platform is elevated above ground, then the trailer is stable during transport, but manual labor is required to lift cargo to elevated height
Solution Approach 1:
The trailer platform height is dynamically adjustable between an elevated first height for stable transport and a second height substantially at ground level for easy loading. This dynamic positioning allows the system to optimize for stability during transit and for ease of operation during loading operations.
4Ease of operation
If ground-level loading is implemented, then loading and unloading is simplified, but the trailer height must be adjustable requiring additional systems
Solution Approach 1:
The height adjustment system is designed as a multi-functional integrated component that simultaneously provides ground-level loading capability, maintains transport stability, and serves as the primary structural support for the insulated enclosure. This universal system eliminates the need for separate auxiliary equipment.

AI summary
A refrigerated trailer adapted for towing by a tow vehicle is provided. The refrigerated trailer can include an insulated enclosure with a door for accessing an interior space and a refrigeration system to maintain a predetermined temperature. The insulated enclosure can be supported by a frame equipped with multiple wheels for mobility. A height adjustment system can be mounted on the frame, and a track system is integrated into the insulated enclosure. The height adjustment system can work in conjunction with the track system to adjust the height of the insulated enclosure between a first and a second height relative to the frame. Advantageously, the refrigerated trailer can enable users to efficiently load and unload cargo without the need for auxiliary equipment or excessive manual effort.
