Solution Overview
Problem
Existing self-moving devices require complex user input for setting working regions and schedules, and existing methods for calculating these areas are cumbersome, involving detection devices and pre-stored programs, making them difficult to operate and adjust.
Innovation Solution
A system where a handheld device moves along the perimeter of the working region to detect and set virtual data for the perimeter, allowing automatic calculation of the area and scheduling of the self-moving device's operations, using a camera and input module to record mark points and calculate the area, simplifying user interaction and reducing the need for complex programming in the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the self-moving device uses complex detection devices and pre-stored programs to calculate working area, then the area calculation accuracy is improved, but the device complexity and operation difficulty increase
Solution Approach 1:
The patent introduces a handheld device as an intermediary tool that the user carries to trace the working area perimeter. This external device handles all complex detection, calculation, and programming functions, allowing the self-moving device itself to remain simple without requiring complex detection devices or pre-stored calculation programs.
Solution Approach 2:
The patent extracts the complex area calculation and detection functions from the self-moving device and places them in an external handheld device. This separation allows the self-moving device to maintain simplicity while still achieving accurate area measurement through the external tool's capabilities.
2Extent of automation
If the self-moving device requires users to input multiple commands for setting working region and schedule, then the automation extent is improved, but the ease of operation deteriorates
Solution Approach 1:
The handheld device performs automatic area calculation and working schedule generation based on the traced perimeter. The system automatically computes the area, determines appropriate working parameters, and sets the schedule without requiring users to manually input multiple commands, thus maintaining automation while simplifying operation to just tracing the perimeter.
Solution Approach 2:
The system performs preliminary automatic calculations of working area and schedule generation before the self-moving device begins its automated work. By pre-computing all necessary parameters based on the traced perimeter, the system eliminates the need for users to input multiple commands during operation.
3Measurement precision
If the self-moving device uses pre-stored programs for area calculation, then the measurement precision is improved, but the ease of manufacture and cost increase
Solution Approach 1:
The patent uses a handheld device as an intermediary that contains the area calculation programming, rather than embedding such programming in the self-moving device. This approach achieves precise measurement while keeping the self-moving device simple and inexpensive to manufacture, as the computational complexity resides in the external tool.
Solution Approach 2:
The system uses the handheld device's computational capabilities to calculate and record the working area, effectively copying the function of complex area measurement programming from the self-moving device to an external tool. This allows accurate measurement without requiring the self-moving device to have expensive embedded programming.
