Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for measuring and monitoring snowpack conditions in avalanche-prone areas are limited by the inability to provide real-time data, lack of internal snowpack information, and high costs, especially in critical and inaccessible locations, and are not economically feasible for small entities.
Innovation Solution
An electronic multi-device ranging rod with sensors for data collection, an autonomous power supply, and telecommunication system for real-time data transmission to a monitoring server, designed for easy installation in steep and critical areas, using optical, thermal, and capacitive sensors to measure snowpack characteristics, and equipped with a wind bracing system for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated nivometeorological stations with ultrasound sensors are installed, then real-time snow thickness monitoring is achieved, but installation is impossible in critical steep areas and requires huge economic investments
Solution Approach 1:
The system segments the monitoring function into distributed electronic ranging rods placed at multiple critical points, each independently measuring local snowpack parameters. This eliminates the need for complex centralized stations while maintaining comprehensive real-time monitoring coverage in steep terrain
Solution Approach 2:
The patent replaces mechanical/ultrasound-based thickness measurement with an electronic/optical ranging system using light time-of-flight measurement. This substitution enables installation in steep areas without requiring level ground or sheltered areas, as the electronic system can be remotely positioned and read via helicopter or binoculars
2Loss of information
If manual nivometric stations with graduated rods are used, then internal snowpack characteristics are obtained, but real-time information and access to critical areas are not provided
Solution Approach 1:
Electronic ranging rods are pre-installed in critical steep areas during summertime with preliminary burial in snow. This preliminary positioning allows immediate data collection when snow accumulates, providing both internal characteristics and real-time monitoring without requiring operator access to dangerous zones
Solution Approach 2:
The system uses an intermediary reading mechanism where measurements are taken remotely via helicopter or binoculars, eliminating the need for operators to physically access critical avalanche areas. This intermediary approach maintains data quality while ensuring safety and real-time capability
3Reliability
If nivometric ranging rods are read periodically by helicopter or binoculars, then measurements in critical areas are possible, but visibility dependence and lack of internal characteristics occur
Solution Approach 1:
The electronic ranging rods enable continuous or near-continuous measurement capability, transforming the periodic discrete readings into an ongoing monitoring process. The electronic system can be read frequently without visibility constraints, maintaining continuous data flow about snowpack evolution in critical areas
Solution Approach 2:
The system measures multiple snowpack parameters simultaneously (snow thickness, internal characteristics, stratigraphy) rather than a single parameter. This multi-parameter electronic measurement provides comprehensive information about snowpack stability and internal structure that single-parameter mechanical rods cannot provide
