Autonomous Soil Compactor Radar Sensor Mounting Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Determining the optimal location for a front radar sensor on autonomous soil compactors is challenging due to various factors such as detection start and end distances, reflection angles, and environmental conditions, and existing solutions fail to provide a common mounting solution for both blade and non-blade configurations.
Innovation Solution
A sensor bracket system that mounts a radar sensor to the machine frame, allowing it to be positioned forward of the roller drum, with a removable angled bracket attaching to the blade cylinder mount on machines with a blade and directly to the front bumper on machines without a blade, ensuring optimal detection angles and articulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a radar sensor is mounted on the machine frame for autonomous detection, then detection capability is improved, but determining the optimal location becomes complex due to multiple factors including detection distances, reflection angles, and environmental conditions
Solution Approach 1:
The mounting bracket is divided into separate components: a main bracket portion that attaches to the machine frame and a sensor mounting portion that holds the radar sensor. This segmentation allows independent optimization of each component's position and orientation, simplifying the overall mounting location determination while maintaining detection capability.
Solution Approach 2:
A dedicated sensor mounting bracket serves as an intermediary component between the machine frame and the radar sensor. This intermediary structure provides a standardized interface that decouples the sensor mounting process from the complex considerations of optimal detection locations, allowing the sensor to be mounted without directly addressing detection distance and angle optimizations.
2Adaptability or versatility
If different mounting solutions are provided for blade and non-blade configurations, then adaptability is improved, but device complexity increases
Solution Approach 1:
The sensor mounting bracket is designed with universal adaptability to accommodate both blade and non-blade compactor configurations through a standardized mounting interface. The bracket can be positioned at different locations on the machine frame depending on the configuration, but uses the same mounting mechanism, thereby providing configuration compatibility without increasing the fundamental mounting solution complexity.

AI summary
A soil compactor machine can include a machine frame; at least one cylindrical roller drum rotatably coupled to the machine frame and rotatable about a drum axis oriented generally transverse to a direction of travel of the compactor machine; and a radar sensor mounted to a front portion of the machine frame and positioned forward of the roller drum, wherein the radar sensor is mounted to the machine frame by a sensor bracket configured to directly mount to the machine frame for both a blade and a non-blade soil compactor machine configuration.
