Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle leveling systems rely on two-axis tilt sensors for pitch and roll adjustments, which are analog and lack precision, especially for structures like recreational vehicles that require more complex attitude corrections.
Innovation Solution
A multi-axis digital sensor, such as a 3-axis or 6-axis gyroscope and accelerometer, provides precise angular orientation data to a controller, enabling the extension and retraction of jacks to achieve desired attitudes through automatic or semi-automatic leveling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If two-axis tilt sensors are used for vehicle leveling, then the system can provide basic pitch and roll adjustments, but the measurement precision is insufficient for complex attitude corrections
Solution Approach 1:
The patent replaces traditional two-axis mechanical tilt sensors with a multi-axis digital sensor system that incorporates gyroscopes and accelerometers. This substitution enables precise measurement of angular orientation in three-dimensional space (pitch, roll, and yaw axes) by utilizing digital sensor fusion algorithms that process data from multiple sensor types, thereby achieving superior measurement precision without proportionally increasing mechanical complexity
Solution Approach 2:
The multi-axis digital sensor system performs multiple functions simultaneously: it measures pitch angle, roll angle, and yaw angle using the same sensor array. The system can detect angular orientation relative to multiple reference lines and planes, providing comprehensive attitude information for complex vehicle leveling applications without requiring separate sensor systems for each measurement function
2Productivity
If automatic leveling control is implemented, then leveling efficiency is improved, but the system complexity and cost increase
Solution Approach 1:
The control system automatically processes sensor data and generates jack control signals without requiring continuous manual intervention. The system self-regulates by continuously monitoring angular orientation measurements, comparing them against desired level attitudes, and autonomously adjusting jack extension lengths to achieve and maintain proper vehicle leveling, thereby improving operational efficiency while keeping the control architecture manageable
Solution Approach 2:
The system implements closed-loop feedback control where multi-axis digital sensor measurements of current vehicle attitude are continuously fed back to the controller. The controller compares these measurements with target level attitudes and automatically adjusts jack positions based on the detected deviations, creating a self-correcting system that improves leveling efficiency through automated feedback-driven adjustments
3Measurement precision
If multi-axis digital sensors are used for precise attitude measurement, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical inclination measurement mechanisms with digital sensor technology. Instead of using mechanical tilt sensors with limited axes, the system employs multi-axis digital sensors (gyroscopes and accelerometers) that provide precise angular orientation data through electronic measurement and digital signal processing, achieving higher precision while reducing mechanical complexity
Solution Approach 2:
The system changes the measurement parameters from limited two-axis tilt angles to comprehensive three-dimensional angular orientation parameters. By utilizing multi-axis digital sensors, the system can simultaneously measure pitch, roll, and yaw angles, providing more complete attitude information with higher precision. This parameter expansion is achieved through digital sensor fusion rather than proportional increases in mechanical complexity
