Movable Vehicle Sensor Positioning for Obstructed Field of View
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicles in manufacturing environments face challenges in maintaining effective sensor visibility due to obstructions caused by products being transported, which can hinder autonomous navigation and operation.
Innovation Solution
The vehicle system includes movable sensors that can be repositioned or adjusted to compensate for obstructions in their field of view, using actuators controlled by a controller that detects obstructions and determines corrective actions to maintain sensor functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are fixed on the vehicle, then device complexity is reduced, but sensor visibility is blocked by products
Solution Approach 1:
The sensor system transitions from a fixed configuration to a dynamic one where sensors can be repositioned along the vehicle perimeter. The sensor is coupled to the vehicle via a positioning mechanism that allows it to move between multiple positions, enabling the sensor to adapt its location based on operational needs and avoid obstructions caused by products.
2Reliability
If sensors are repositioned to avoid obstructions, then sensor visibility is maintained, but device complexity increases
Solution Approach 1:
The sensor system is divided into functionally independent components: the sensor unit itself, the positioning mechanism with actuator, and the control system. This segmentation allows each component to be optimized independently and facilitates maintenance and replacement without affecting the entire system.
Solution Approach 2:
The system employs periodic scanning or monitoring to detect obstructions and triggers repositioning actions only when necessary. The controller receives signals from the sensor, detects obstructions, and activates the actuator to reposition the sensor, creating a cyclic detect-actuate-monitor operation that maintains functionality while minimizing unnecessary mechanical movement.
3Reliability
If multiple sensors are added to ensure coverage, then sensor visibility is maintained, but device complexity and cost increase
Solution Approach 1:
A single sensor unit is designed to perform multiple functions by being repositioned to different locations around the vehicle. The same sensor can monitor different areas at different times, replacing the need for multiple fixed sensors. The positioning mechanism enables one sensor to serve the role of what would otherwise require several sensors distributed at fixed positions.
