Solution Overview
Problem
Conventional auto clean machines struggle to differentiate between rigidity type and soft type objects, leading to potential damage or failure to navigate around objects like curtains.
Innovation Solution
An object determining system that includes an air ejection device, a distance detecting circuit, and a determining circuit, which ejects air to detect distance variations and determine whether an object is a rigidity type or soft type without physical collision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If collision method is used to determine object type, then object type can be determined, but object may be damaged due to collision
Solution Approach 1:
The patent introduces air as an intermediary medium to transfer information about the object's rigidity without direct mechanical contact. The air ejection device blows air onto the object, and the distance detecting circuit measures how the object responds to this air flow, allowing type determination without collision damage.
Solution Approach 2:
The patent replaces the direct mechanical collision method with a pneumatic field-based detection method. Instead of using physical contact to determine object type, the system uses air flow interaction combined with optical or electromagnetic distance detection to infer object properties non-contactly.
2Loss of information
If optical or lidar method is used to detect object, then object presence can be detected, but object type cannot be determined
Solution Approach 1:
The patent performs a preliminary action by ejecting air onto the object before final detection. This air ejection causes soft objects to deform or move while rigid objects remain unchanged, creating distinct distance variations that the detection circuit can measure to determine object type.
Solution Approach 2:
The patent adds a temporal dimension to the detection process by measuring distance before and after air ejection. This creates a dynamic measurement approach where the change in distance over time provides information about object rigidity, complementing the static presence detection capability.
