Solution Overview

Problem

Transportation vehicles using contactless traction engines face challenges in maintaining optimal separation distance from traction surfaces to avoid damage and vibration, as existing suspension systems have limited reaction time and are ineffective in predicting surface unevenness at high velocities.

Innovation Solution

A predictive suspension system that collects and processes data on traction surface profiles to provide advance control of traction engines and suspension actuators, combined with a coupled suspension system that dynamically adjusts traction engine position and power based on real-time sensor readings, and a torquing vehicle system that allows for orientation adjustments along roll, pitch, and yaw axes.

Solution Approach 1:

The predictive suspension system performs preliminary scanning of the traction surface to identify upcoming irregularities before the vehicle reaches them. This advance detection allows the control system to prepare appropriate suspension adjustments, maintaining optimal separation distance while avoiding damage from surface unevenness.

Inventive Principle:

Solution Approach 2:

The system continuously monitors the actual separation distance between the traction engine and traction surface using sensors, and feeds this information back to the control system. This real-time feedback enables dynamic adjustment of the separation distance to maintain optimal traction while preventing damage from excessive proximity to uneven surfaces.

Solution Approach 1:

The suspension system dynamically adjusts the separation distance between the traction engine and traction surface based on real-time surface conditions and vehicle state. This dynamic adjustment allows the system to maintain close proximity for optimal traction on smooth surfaces while increasing separation when surface irregularities are detected, thus avoiding damage.
