Elastic Strain-Based Obstacle Detection for Cleaning Robots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning robots require multiple detection components for obstacle avoidance, which increases space occupancy and complicates the arrangement of other components due to the limited detection range of laser radars.
Innovation Solution
An obstacle detection device with an action component, an elastic component, and a detection component that generates strain signals upon deformation, allowing the controller to control the cleaning robot's movement for effective obstacle avoidance, thereby increasing the detection range while reducing the number of required detection components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple detection components are provided to increase detection range, then obstacle detection capability is improved, but space occupancy increases and component arrangement becomes complicated
Solution Approach 1:
The laser radar is designed to perform multiple functions: both obstacle detection and navigation. By making the detection component universal, the patent reduces the need for separate dedicated detection components, thereby simplifying component arrangement while maintaining comprehensive obstacle detection capability
Solution Approach 2:
The patent combines obstacle detection function with the existing navigation laser radar. Instead of adding separate detection components, the navigation radar is made to serve dual purposes, merging detection and navigation functions into a single component system
2Reliability
If multiple detection components are provided to increase detection range, then obstacle detection capability is improved, but space occupancy increases
Solution Approach 1:
The laser radar performs both navigation and obstacle detection functions, eliminating the need for additional dedicated detection components. This multi-functionality reduces the total space required for housing multiple separate components while maintaining comprehensive detection coverage
Solution Approach 2:
By merging obstacle detection with navigation functions in a single laser radar component, the patent reduces the overall footprint required for detection systems, freeing up space for other robot components
