Portable Trailer Stand with Telescopic Posts and Adjustable Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable trailer stands lack the ability to effectively stabilize and support trailers of varying sizes and inclines, particularly when the trailer's landing gear may fail or collapse, and they are not easily adjustable for non-parallel surfaces.
Innovation Solution
A portable trailer stand with telescopic posts and a adjustable frame, featuring a kingpin-receiving groove and jackscrew mechanism for height adjustment, along with spring-loaded wheels for easy repositioning, allows for stable support on uneven surfaces and accommodates trailers of different sizes and inclines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a portable trailer stand uses fixed-length posts, then the structure is simple, but it cannot accommodate trailers of varying sizes and inclines
Solution Approach 1:
The patent applies telescopic posts with adjustable lengths instead of fixed-length posts. The posts can be extended or retracted to accommodate different trailer heights and inclines, transforming the static structure into a dynamic one that adapts to varying conditions while maintaining reasonable structural complexity through standardized telescopic mechanisms.
Solution Approach 2:
The patent changes the length parameter of the support posts to accommodate different trailer sizes. By making the posts adjustable in length, the device can adapt to various trailer configurations without requiring multiple different stand models, thus improving versatility without proportionally increasing complexity.
2Adaptability or versatility
If the trailer stand uses non-adjustable frame, then the manufacturing is simpler, but it cannot support non-parallel surfaces
Solution Approach 1:
The patent incorporates an adjustable frame mechanism that allows the frame to be reconfigured for different angles and orientations. This dynamic adjustment capability enables the stand to support trailers on non-parallel surfaces while using standardized adjustable components that maintain manufacturing feasibility.
3Ease of operation
If the trailer stand uses fixed height, then the structure is more stable, but it cannot be easily repositioned for different locations
Solution Approach 1:
The patent combines fixed base elements for stability with adjustable height mechanisms that allow repositioning. The base remains stable and fixed, while the telescopic posts and adjustable frame components enable height changes and reconfiguration for different locations, separating the stability function from the positioning function.
4Adaptability or versatility
If the trailer stand lacks adjustment mechanisms, then the device is simpler, but it cannot accommodate different trailer configurations
Solution Approach 1:
The patent introduces telescopic posts and adjustable frame mechanisms that enable the device to adapt to different trailer configurations. These adjustment mechanisms use standardized components and systematic design patterns that increase functionality while controlling overall device complexity through modular construction.

AI summary
Example portable trailer stands for supporting parked trailers are disclosed herein. Some example portable trailer stands disclosed herein comprise two telescopic posts supporting a generally horizontal beam. Some examples include spring-loaded retractable wheels for selectively installing and removing the trailer stand from underneath a trailer left parked on a driveway. After being positioned under the trailer, the posts extend to lift the beam solidly up against the underside of the trailer. To accommodate conditions where the driveway is not parallel to the trailer's underside, some example posts can be lengthened independently and have angular play that allows the beam to tilt. In some examples, the horizontal axle of the trailer stand wheels is perpendicular to the beam so that the trailer stand can be readily installed from either the front or side of the trailer. Some examples have a kingpin-receiving groove in the beam or have some other kingpin-receiving feature.
