Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Robot dust collectors with detection devices protruding upward are prone to getting caught under objects, making it difficult for the device to escape and perform avoidance actions.
Innovation Solution
A detection device with an optical sensor, a linearly movable cover member, and a motion sensor that detects the movement of the cover member to detect contact with objects, allowing the device to adjust its movement accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the detection device protrudes upward from the top surface to enable non-contact detection, then the detection capability is improved, but the device is likely to get caught on the underside of objects
Solution Approach 1:
The detection device is designed with movable components that allow it to dynamically adjust its position. The cover member can move linearly to expose or protect the optical sensor, and the detection member moves with the cover member to detect contact forces, enabling the system to adapt between detection mode and protection mode
Solution Approach 2:
The cover member acts as an intermediary between the optical sensor and the external environment. It provides a protective barrier that can be moved to prevent direct contact with objects while still allowing the optical sensor to function when the cover is in the exposed position
2Reliability
If the detection device is made robust to avoid getting caught, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The detection device is segmented into distinct functional components: the optical sensor for non-contact detection, the cover member for protection and contact detection, the detection member coupled to the cover member, and the motion sensor for detecting movement. This segmentation allows each component to perform its specific function with simple structure
Solution Approach 2:
The cover member serves multiple functions: it protects the optical sensor from damage, acts as a contact detection element when it touches objects, and provides structural support for the detection member. This multi-functionality reduces the need for additional protective components
