Trailer Leveling via Mobile Orientation Display and Drive Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Leveling a trailer, such as a caravan or mobile home, is typically strenuous and time-consuming, as it requires precise horizontal alignment to prevent objects from sliding or liquids from flowing, which existing methods fail to address efficiently.
Innovation Solution
A method utilizing a mobile terminal connected to a wireless mobile network to display a graphical representation of the trailer's orientation relative to a horizontal plane, allowing users to operate an auxiliary drive via touch-sensitive controls on the terminal's screen to adjust the trailer's position and achieve level alignment without a dedicated leveling device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional manual leveling methods are used, then the trailer can be leveled, but the process is strenuous and time-consuming
Solution Approach 1:
The patent replaces manual mechanical leveling operations with an automated electronic system. A mobile terminal displays the trailer's orientation data and provides touch-sensitive controls that automatically adjust the leveling process, eliminating the need for strenuous manual adjustment while significantly reducing leveling time
Solution Approach 2:
The system enables self-service leveling by allowing the user to simply touch the screen interface, which then automatically performs the complex adjustments needed to level the trailer. The system self-regulates the leveling process based on the displayed orientation data, minimizing user effort while maintaining high productivity
2Measurement precision
If specialized leveling equipment is used, then leveling precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies universality by using a multi-functional mobile terminal device that serves both as the orientation detection interface and the control system. The mobile terminal, which users already possess, displays graphical representations of trailer orientation and provides touch-sensitive controls, eliminating the need for specialized dedicated leveling equipment while maintaining high measurement precision
Solution Approach 2:
The mobile terminal acts as an intermediary between the trailer's orientation sensors and the user. It receives orientation data, processes it into graphical representations, and provides touch-sensitive controls that translate user input into precise adjustment commands, thereby achieving high measurement precision without requiring complex specialized equipment

AI summary
The invention relates to a method for leveling a trailer (10), in which a representation (38) is displayed on a screen (34) of a mobile device (32) in a first area (36) of the screen (34), illustrating the alignment of the trailer (10) relative to a horizontal plane. Simultaneously, at least two and at most four control elements (46a-d) are displayed as operating surfaces on the screen (34) of the mobile device (32) in respective, adjacent, touch-sensitive second areas (45a-d) of the screen (34), wherein an auxiliary drive (30) designed to drive the trailer (10) can be operated by a person touching the second areas (45a-d), thereby enabling the trailer (10) to be driven for leveling purposes.
