Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soil compaction methods struggle to ensure a sufficient but not excessive compaction level, as they rely on manual verification of compactor travel and compaction effects, which can lead to inconsistent results and potential soil structure damage.
Innovation Solution
A method and soil compactor system that uses location and travel data to generate an as-built model of compaction level, determining boundaries and an up-to-date travel path, and continuously measures and updates compaction levels to ensure accurate and controlled compaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual verification of compactor travel and compaction effects is used, then the compaction process is simple to operate, but the compaction level consistency and reliability deteriorate
Solution Approach 1:
The patent replaces manual verification methods with automated electronic measurement and control systems. Location data from GPS receivers and compaction measurements from sensors are processed by a control unit to automatically monitor and control compaction levels, eliminating the need for manual verification while ensuring consistent and reliable compaction results.
Solution Approach 2:
The patent implements a feedback control system where compaction measurements are continuously taken and compared against target compaction levels. The control unit receives location data and compaction measurements, processes this information, and provides feedback to adjust the compaction process, ensuring consistent compaction quality and reliability throughout the work area.
2Reliability
If excessive compaction effect is applied to ensure sufficient compaction level, then the compaction reliability is improved, but the soil structure integrity deteriorates
Solution Approach 1:
The control unit continuously receives compaction measurements and location data, comparing actual compaction levels against target values. This feedback mechanism allows the system to adjust the compaction process in real-time, ensuring sufficient compaction is achieved without applying excessive compaction effects that would damage soil structure.
Solution Approach 2:
The patent employs dynamic adjustment of compaction parameters based on real-time measurements and location data. The system adapts the compaction process to local conditions, modifying compaction intensity and coverage area dynamically to achieve reliable compaction while protecting soil structure from excessive compaction damage.
3Manufacturing precision
If multiple passes over each area are performed to achieve sufficient compaction, then the compaction level is improved, but the productivity deteriorates
Solution Approach 1:
The system uses feedback from compaction measurements and location tracking to determine when sufficient compaction has been achieved in each area. This eliminates unnecessary multiple passes by providing real-time information about compaction status, allowing the compactor to move to new areas once target compaction levels are reached, thereby improving productivity while maintaining compaction quality.
Solution Approach 2:
The control unit plans and monitors the compaction process in advance, using location data to track which areas have been compacted and to what level. This preliminary planning and monitoring prevents redundant passes by ensuring each area is compacted only as many times as necessary to achieve the target compaction level.
4Measurement precision
If automated location tracking and compaction measurement systems are implemented, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The control unit serves multiple functions: it receives and processes location data from GPS receivers, collects compaction measurements from sensors, compares measurements against target values, and controls the compaction process. This multi-functionality consolidates what would otherwise be separate systems into a single integrated unit, improving measurement precision while minimizing the increase in device complexity.
Solution Approach 2:
The patent combines location tracking functionality and compaction measurement functionality into an integrated system managed by a single control unit. By merging these functions, the system achieves high measurement precision for both location and compaction levels while avoiding the complexity of having completely separate tracking and measurement systems.

AI summary
A method for compacting soil by a soil compactor comprising at least one soil compacting device, and a soil compactor. The method comprises generating an as-built model of compaction level covering at least a work order area to be compacted, determining boundaries for the work order area and determining location data for an area over which the at least one soil compacting device travels. Furthermore, it is generated an up-to-date travel path to be driven to cover the work order area by the at least one soil compacting device by using compactor operation for compacting soil and measurement function for measuring the compaction level of soil while compacting. The soil compactor is driven according to the up-to-date travel path and a location-specific as-built compaction level of soil and determined boundaries for the work order area are saved to the as-built model of compaction level.
