Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current composting methods struggle to optimally control aeration across heterogeneous organic waste masses, leading to suboptimal degradation conditions due to non-representative measurement points and safety issues with manual probing.
Innovation Solution
A retractable, mobile probe system that measures physico-chemical parameters across multiple points in a composting zone, allowing for multipoint, automatic data collection and adaptive aeration control, reducing safety risks and improving degradation monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual measurements are performed at a single point by inserting a probe, then safety risks are reduced and measurement precision is improved, but the device complexity increases and productivity decreases
Solution Approach 1:
The patent replaces manual mechanical probe insertion with an automated mobile measuring device that moves through the composting zone. The device includes a mobile platform with sensors that automatically measure temperature and oxygen content at multiple points without human intervention, thereby maintaining measurement precision while eliminating safety risks and improving productivity through automated data collection across the entire composting mass.
2Ease of operation
If measurements are taken at a single point, then device complexity is reduced and ease of operation is improved, but measurement precision deteriorates due to heterogeneity of the waste
Solution Approach 1:
The patent divides the composting zone into multiple measurement points arranged in a grid pattern. The mobile device systematically visits each point to collect data, transforming a single-point measurement system into a multi-point segmentation approach. This allows the heterogeneity of the waste to be captured through spatial distribution of measurements while maintaining ease of operation through automated navigation and data collection at each segmented location.
Solution Approach 2:
The patent transitions from single-point (zero-dimensional) measurement to multi-point spatial measurement by introducing spatial dimensions. The mobile device moves through the composting zone collecting data across multiple coordinates, creating a three-dimensional map of temperature and oxygen distribution. This dimensional expansion captures waste heterogeneity while the automated system maintains operational simplicity.
3Measurement precision
If a stationary probe is placed in the heart of a windrow, then measurement precision is improved for that location, but adaptability deteriorates because the setting in motion of organic mass is not always possible or desirable
Solution Approach 1:
The patent transforms the stationary probe concept into a mobile measuring device that can dynamically adapt its position and measurement locations. The device moves through the composting zone on a mobile platform, allowing it to access different locations as needed. This dynamic capability enables the system to maintain measurement precision at various points while adapting to different composting configurations, whether the mass is stationary or moving, and whether enclosed or open.

AI summary
The invention concerns a composting method, and corresponding device, for an organic mass placed in a composting zone, comprising the following steps: measuring, by means of a probe, in at least one measuring point of the composting zone, at least one physico-chemical parameter, and aerating the organic mass. The invention is basically characterized in that the probe is inserted in the organic mass, and in that aeration comprises a step of sequential blowing, a function of the measuring step. Advantageously, the probe is mobile so that it can cover any point of the composting zone.
