Air Ejection Object Detection for Auto Clean Machine Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional auto clean machines struggle to differentiate between rigid and soft objects, leading to potential damage or failure to navigate around soft obstacles, as existing methods like collision detection can break fragile items or fail to recognize curtains and similar soft objects.
Innovation Solution
An object determining system employing an air ejection device to detect distance variations, using a distance detecting circuit to differentiate between rigid and soft objects by measuring deformation caused by air ejection, and a determining circuit to classify objects without physical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If collision detection is used to determine object type, then the auto clean machine can identify rigid objects, but fragile items may be broken and soft objects may be knocked away
Solution Approach 1:
The patent introduces air as an intermediary medium between the auto clean machine and the object. The air ejection device propels air toward the object, and the distance detecting circuit measures distance changes caused by air interaction with the object. This intermediary approach allows object type determination without direct physical contact, thereby preventing damage to fragile and soft objects while maintaining detection accuracy.
Solution Approach 2:
The patent replaces the traditional mechanical collision detection system with a non-contact measurement system. Instead of using physical sensors that require direct contact or collision with objects, the system uses an air ejection device combined with a distance detecting circuit to measure distance variations caused by air interaction. This substitution eliminates mechanical impact while preserving the ability to distinguish between rigid and soft objects.
2Loss of information
If optical or lidar detection is used to detect objects, then the auto clean machine can detect object presence, but it cannot determine whether the object is rigid or soft
Solution Approach 1:
The patent changes the measurement parameter from static distance (used in optical/lidar detection) to dynamic distance variation (used in air ejection detection). By measuring how distance changes when air is ejected at the object, the system can infer object properties such as rigidity. Soft objects deform under air pressure causing larger distance changes, while rigid objects show minimal distance variation, enabling accurate object type classification.
