Compactor Plate Force Distribution Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing add-on compactors face challenges in achieving uniform static force distribution when pressing onto a surface, leading to potential damage and uneven soil compaction due to non-orthogonal loading, which is difficult for operators to detect in real-time.
Innovation Solution
The method involves using at least two sensors to detect and record the static force distribution, determining differences in measured forces, and triggering actions when limit values are exceeded, such as generating signals to the operator or interrupting vibration, to ensure uniform loading and prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the attachment compactor is pressed onto the surface without real-time monitoring, then the operation is simple, but the static force distribution becomes uneven causing damage and uneven soil compaction
Solution Approach 1:
The compactor plate is divided into multiple measurement zones with sensors distributed across different locations. Each sensor independently measures the static force at its specific position, enabling segmentation of the force distribution measurement into discrete detectable points that collectively represent the overall distribution pattern.
Solution Approach 2:
The system continuously monitors static force distribution through sensors and provides real-time feedback to the operator. When uneven distribution is detected, the system signals the operator to adjust the compactor orientation, creating a closed-loop feedback mechanism that maintains reliable operation without requiring complex automated control.
2Measurement precision
If the operator manually checks for perpendicular orientation, then the monitoring is simple, but the detection precision of non-orthogonal loading is insufficient
Solution Approach 1:
Different regions of the compactor plate are equipped with sensors that measure local static force characteristics. By analyzing the spatial pattern of forces at different locations, the system can precisely determine whether the loading is orthogonal or oblique, providing high measurement precision through local force quality assessment.
Solution Approach 2:
The manual mechanical checking of orientation by the operator is replaced with an automated sensor-based detection system. The sensors electronically measure static forces and compute orientation information, substituting mechanical judgment with precise electronic measurement and calculation.
3Measurement precision
If multiple sensors are installed to detect static force distribution, then the measurement precision improves, but the device complexity increases
Solution Approach 1:
The sensor system is designed to perform multiple functions: measuring static force magnitude, determining force distribution pattern, detecting non-orthogonal loading, and providing orientation information. This multi-functionality reduces the need for separate measurement systems and minimizes overall device complexity despite using multiple sensors.
Solution Approach 2:
Multiple sensor measurements are merged and processed together to derive comprehensive force distribution characteristics. The system combines data from individual sensors to calculate overall static force, distribution uniformity, and orientation, merging multiple measurement streams into unified diagnostic information.
