Carriage Recesses for Unobstructed Obstacle Detection Light
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In autonomous travel robots, the carriage obstructs the search light emitted by detectors, leading to degraded obstacle detection accuracy due to blockage, which affects the navigation and safety of the transport system.
Innovation Solution
The carriage is designed with recesses on its side surfaces to allow the search light from detectors on the traveling device to pass through, and the detectors are positioned at different heights to enhance obstacle detection, preventing blockage and improving accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the carriage is arranged above the traveling device, then the transport system structure is simplified, but the search light is blocked by the carriage which degrades obstacle detection accuracy
Solution Approach 1:
The carriage body is segmented by providing recesses (opening portions) in its side surfaces, creating light transmission paths that allow search light to pass through the carriage structure rather than being completely blocked, thus maintaining both structural simplicity and detection accuracy
Solution Approach 2:
The recesses in the carriage act as intermediary light transmission channels, allowing the search light to penetrate through the carriage body to detect obstacles in front of the traveling device, resolving the conflict between carriage positioning and detection capability
Applied Scientific Principles
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 configuration ensures unobstructed search light emission, enhancing the detection range and accuracy of obstacles, thereby improving the navigation and safety of the transport system by preventing degradation of detector performance.
Implementation Method 1
the detector, for example, emits search light over a predetermined angle and detects reflected light, so as to detect presence or absence of the obstacle and measure a distance to the obstacle

AI summary
The carriage is coupled to the traveling device including a driving wheel and is towed and moved by the traveling device. The carriage includes: a traveling wheel provided in a bottom portion of the carriage; an accommodating part for accommodating the traveling device; and a passage which is provided on a side surface of the carriage and through which light emitted from a detector passes, the detector being provided in the traveling device to detect an obstacle around the traveling device.
