Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-moving devices require complex user input to set working regions and schedules, which can be inconvenient, especially when the environment changes, and often necessitate additional hardware like detection devices for calculating working areas.
Innovation Solution
A method using a handheld device to detect and calculate the area of a self-moving device's working region by moving along the perimeter, allowing for automatic setting of schedules and control, simplifying user interaction and eliminating the need for complex calculation programs in the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the self-moving device is equipped with detection devices and complex calculation programs to automatically calculate working area, then the area calculation accuracy is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts the area calculation function from the self-moving device and relocates it to a handheld device. The self-moving device only needs to execute simple commands while the complex calculation is performed externally by the handheld device using coordinates obtained during the device's movement along the perimeter. This resolves the contradiction by maintaining calculation accuracy while significantly reducing device complexity.
Solution Approach 2:
The patent introduces a handheld device as an intermediary between the user and the self-moving device. The handheld device captures coordinates during perimeter traversal and performs the area calculation, acting as a mediator that handles the complex computational tasks. This allows the self-moving device to remain simple while still achieving accurate area measurement through the intermediary's processing capabilities.
2Adaptability or versatility
If the user manually sets working region and schedule parameters, then the device can adapt to different environments, but the ease of operation deteriorates due to complex menu navigation and programming
Solution Approach 1:
The patent implements self-service by enabling the handheld device to automatically calculate the working area and generate schedule parameters based on the captured perimeter coordinates. The system performs area calculation and schedule generation autonomously without requiring manual intervention for complex computations, while still allowing environmental adaptation through the calculated parameters.
Solution Approach 2:
The patent applies preliminary action by having the handheld device pre-calculate the working area and generate schedule parameters before the self-moving device begins operation. The perimeter is traced once to obtain all necessary coordinates, and all subsequent operations use these pre-calculated values, eliminating the need for repeated manual setup when environmental conditions change.
3Extent of automation
If the self-moving device uses pre-stored programs and automatic movement to define working region, then the area calculation automation is improved, but the ease of operation worsens due to the need for pushing or presetting programs
Solution Approach 1:
The patent inverts the traditional approach by having the handheld device (external tool) perform the perimeter traversal and calculation instead of the self-moving device performing automatic movement. The user simply guides the handheld device along the perimeter while it captures coordinates, and the area is calculated automatically. This reverses which device performs which function, achieving automation without requiring the self-moving device to have complex movement capabilities.
