Piste Grooming Vehicle Predictive Topography Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing piste grooming vehicles struggle to maintain consistent piste preparation quality due to changes in topography caused by snowfall, melting, or snow transportation, which are not accounted for before the vehicle travels on the piste section.
Innovation Solution
A method and vehicle configuration that detect the actual topography in front of the vehicle using contactless measuring technology, compare it to a reference topography, and adjust the piste grooming device accordingly, allowing for predictive actuation and improved piste grooming quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If piste grooming is performed using conventional methods without predictive topography detection, then the device complexity is reduced, but the manufacturing precision of piste preparation deteriorates due to unaccounted topography changes
Solution Approach 1:
The system performs preliminary detection of the piste topography before the grooming vehicle reaches the section using ahead detection technology. This allows the control unit to pre-calculate required grooming parameters and predictively adjust the grooming device settings before actual contact with the snow, ensuring optimal preparation quality while maintaining manageable system complexity through automated predictive control
Solution Approach 2:
The invention replaces manual mechanical adjustment of grooming parameters with an automated control system that uses optical or radar detection technology to measure topography ahead of the vehicle. The control unit automatically translates detection data into grooming device adjustments, substituting mechanical manual operation with an integrated sensor-control-actuator system that improves precision without proportionally increasing complexity
2Reliability
If topography changes are detected and accounted for in real-time, then the reliability of piste preparation is improved, but the loss of time for data processing and adjustment increases
Solution Approach 1:
The system detects and analyzes topography changes in advance before the grooming vehicle reaches the affected section. The control unit pre-calculates the necessary adjustments to grooming parameters based on the detected variations, allowing the system to be already prepared and adjusted by the time it reaches the problematic area, thus maintaining reliability while minimizing actual processing time during grooming operation
Solution Approach 2:
The ahead detection technology allows the system to quickly scan and identify topography changes at a distance, enabling rapid data acquisition and processing. The control unit prioritizes processing only the critical parameters needed for grooming adjustment, skipping unnecessary computations and focusing on the most relevant topography variations to reduce overall processing time while maintaining preparation consistency
