Moisture Sensor Bale Wrapping Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Agricultural bales often fail to be properly wrapped during the baling process, leading to them falling apart upon release due to inadequate or incomplete wrapping by the baling apparatus.
Innovation Solution
The baling apparatus employs moisture sensors to detect whether the wrapping material is sufficiently wrapped around the bale by comparing the moisture levels of the wrapped and unwrapped surfaces, using a control device to determine if the bale is properly secured before release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If moisture sensors are used to detect wrapping quality, then bale wrapping reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where moisture sensors detect the moisture content of the bale surface, and this information is fed back to a control device that compares the readings and determines whether the wrapping is sufficient. This closed-loop feedback system automatically detects wrapping quality and prevents release of improperly wrapped bales, thereby improving reliability while managing complexity through automated decision-making.
2Measurement precision
If multiple sensors are used to detect wrapping quality, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent divides the sensor system into multiple discrete moisture sensors positioned at different locations on the bale surface. Each sensor independently measures moisture content at its specific position, providing segmented data points that collectively enable comprehensive wrapping quality assessment. This segmentation approach improves measurement precision by capturing spatial variations in wrapping coverage while keeping each individual sensor simple.
Solution Approach 2:
The patent employs multiple sensors that may detect more information than strictly necessary, including redundant measurements and potentially excessive data points. This excessive action ensures that wrapping quality is thoroughly verified across the entire bale surface, improving detection precision by capturing edge cases and partial wrapping scenarios that a single sensor might miss.
3Productivity
If automatic detection system is implemented, then productivity is improved, but device complexity increases
Solution Approach 1:
The patent implements a self-service automatic detection system where the moisture sensors and control device autonomously monitor wrapping quality and make release decisions without human intervention. The system serves itself by automatically detecting wrapping sufficiency, comparing sensor readings, and controlling bale release based on predetermined criteria, thereby improving productivity while containing complexity through self-managing operations.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method ensures that agricultural bales are only released when properly wrapped, preventing them from falling apart and allowing for efficient operation without requiring changes to the wrapping material or baling process.
Implementation Method 1
a first plurality of sensors (34, 36) disposed on a support (32) extending across an opening to the bale forming chamber adapted to measure a moisture level of a surface of the agricultural bale

AI summary
A baling apparatus comprising a bale forming chamber in which an agricultural bale B is formed, wrapped and subsequently released is disclosed. The baling apparatus further comprises a support 32 extending adjacent the bale forming chamber, the support incorporating a plurality of sensors arranged upon the support, wherein the sensors are adapted to measure a surface property of the at least one surface. Since the surface property of the surface of an unwrapped bale will differ from the surface property of the surface of the wrapped bale, the disclosed baling apparatus has as an advantage that it can be detected whether the wrapping material 40 is sufficiently wrapped around the formed bale B to permit release of the agricultural bale without the agricultural bale B falling apart.
