Robotic Work Tool Coordination With Anonymous Area Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As robotic work tool systems become more advanced, they rely on larger datasets for operation, including user schedules and area information, which may contain sensitive data that users are not willing to share, and legislative requirements demand data protection to ensure privacy.
Innovation Solution
The robotic work tool system employs a data anonymous function to obscure the identity of private data sources and locations, ensuring data privacy by rendering received data anonymous before processing and transmission, and uses a centralized planning system to manage and update operating instructions for multiple robotic tools based on user requirements and environmental data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a centralized planning system collects and processes user schedules and area information for robotic work tool operation, then the system can provide improved control and coordination of multiple robotic tools, but user privacy is compromised due to collection of sensitive data
Solution Approach 1:
The patent introduces a boundary wire as an intermediary communication medium between the robotic work tool and the external environment. The boundary wire transmits control signals and data without requiring direct wireless communication that could expose sensitive user information. This intermediary approach enables centralized planning and coordination while maintaining user privacy by avoiding direct digital connections that could leak sensitive data.
Solution Approach 2:
The patent extracts only the essential operational data needed for coordinated control from the complete user information set. By selectively collecting only location and basic operational parameters through the boundary wire system, rather than comprehensive user schedules and personal data, the system achieves multi-robot coordination while minimizing privacy intrusion.
2Productivity
If more tasks and work areas are automated with dedicated robots, then productivity increases, but the complexity of controlling multiple robotic work tools increases
Solution Approach 1:
The patent merges the control functions for multiple robotic work tools into a single centralized planning system. Instead of each robot having independent complex control systems, the boundary wire-connected central system coordinates all robots, simplifying individual device complexity while enabling sophisticated multi-robot productivity through unified control.
