Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If laser radar and cleaning computing units are installed in cleaning devices, then positioning precision and task management capability are improved, but device cost increases
Solution Approach 1:
The patent introduces a server as an intermediary component that receives positioning data from cleaning devices via Bluetooth or WiFi modules. The server performs the complex trajectory calculation and task completion determination, eliminating the need for expensive laser radar and computing units in the cleaning devices themselves. This mediator approach transfers computational complexity from the device to the server, resolving the contradiction between positioning precision and device complexity.
Solution Approach 2:
The patent replaces the traditional mechanical/optical positioning system (laser radar) with an electronic communication-based system using Bluetooth or WiFi modules combined with server-side processing. This substitution uses electromagnetic signal transmission and server-based computational geometry to achieve positioning and task monitoring, reducing device complexity while maintaining measurement capability through the server's processing power.
2Measurement precision
If laser radar and computing units are installed in cleaning devices, then task completion monitoring accuracy is improved, but device cost increases
Solution Approach 1:
The server acts as an intermediary that receives positioning data from cleaning devices and performs trajectory point matching against the monitoring region map. This server-side processing determines task completion status without requiring complex computing units in the cleaning devices, achieving accurate task completion monitoring while keeping device complexity low.
Solution Approach 2:
The patent creates a digital copy of the monitoring region through a monitoring region map that stores spatial information. The server matches trajectory points against this digital map to determine task completion, replacing the need for physical sensors and computing units in the cleaning device. This copying approach enables accurate monitoring through information representation rather than physical measurement hardware.
3Device complexity
If only operating time is monitored without positioning data, then device complexity is reduced, but task management efficiency deteriorates
Solution Approach 1:
The server serves as an intermediary that processes simple positioning data from cleaning devices equipped with only Bluetooth or WiFi modules. By performing the complex trajectory analysis and task completion determination on the server side, the system achieves efficient task management without requiring complex devices, thus resolving the contradiction between device complexity and productivity.
Solution Approach 2:
The patent replaces physical positioning hardware (laser radar) with electronic communication modules (Bluetooth/WiFi) combined with server-based computational processing. This substitution enables accurate trajectory tracking and task management efficiency through software-based solutions rather than hardware-based measurement systems, improving productivity while maintaining low device complexity.

AI summary
A method for indoor operation monitoring of a cleaning device is provided, which is executed by a server of a system for indoor operation monitoring of a cleaning device. The method includes generating a work region map; forming a monitoring map based on location fingerprints taken from a work region in the work region map; determining working trajectory points of the cleaning device based on a set of positioning data; obtaining a monitoring task region through a monitoring terminal; determining, based on the monitoring map, a monitoring region map corresponding to the monitoring task region, matching the working trajectory points with the monitoring region map, and determining cumulative trajectory points within the monitoring task region; and in response to determining that a count of the cumulative trajectory points and distribution situation of the cumulative trajectory points satisfy a preset update condition, sending a display update instruction to the monitoring terminal.
