Method for operating a mobile self-propelled device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile, self-driving devices like robotic vacuum cleaners and lawnmowers face challenges in balancing power consumption with the need for efficient information transmission and user interaction, particularly in standby modes.
Innovation Solution
A method that operates these devices in three communication modes: offline, online, and a mixed mode where the device is temporarily online and offline, allowing controlled network connection management to reduce power consumption while ensuring timely notifications and user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the network connection is maintained continuously (second communication mode), then the response speed to user commands is improved, but the power consumption increases
Solution Approach 1:
The device implements periodic network connections in the third communication mode, switching between offline and online states at defined intervals. This allows the device to maintain functionality while reducing power consumption compared to continuous connection, as the network module is activated only during specified time windows for sending notifications or receiving commands.
2Use of energy by moving object
If the network connection is deactivated permanently (first communication mode), then the power consumption is reduced, but the user cannot control the device or receive notifications
Solution Approach 1:
The system dynamically adjusts its communication state based on operational needs and user requirements. The device can switch between three communication modes (first, second, and third modes), allowing the network connection status to be flexible rather than static. This enables optimization of power consumption while maintaining user control capabilities when needed.
3Use of energy by moving object
If the device operates in mixed mode with temporary online/offline switching, then the power consumption is reduced, but the complexity of network management increases
Solution Approach 1:
The device autonomously manages its own network connection state according to predefined rules and operational context. The control unit automatically determines when to switch between online and offline states based on the mixed mode configuration, eliminating the need for manual user intervention in network management while reducing power consumption through intelligent, self-directed connection control.
