Lawn Mower Control for Ineffective Non-Grass Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intelligent lawn mowers face inefficiencies in mowing special areas like flagstone paths and manhole covers, as they avoid these regions, leading to incomplete mowing and increased path complexity, reducing overall mowing efficiency.
Innovation Solution
The introduction of an 'ineffective area' concept on a map, allowing the lawn mower to pass through designated non-grass areas without avoiding them, using a non-contact sensor to identify and a contact sensor to manage obstacles, simplifying the mowing path and improving efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lawn mower avoids non-grass areas based on sensor information, then the mower can prevent damage from obstacles, but the mowing efficiency decreases due to path complexity and incomplete coverage of special areas
Solution Approach 1:
The patent applies local quality by differentiating between two types of non-grass areas: ineffective areas (where the sensor incorrectly identifies grass as non-grass) and actual obstacle areas. The mower uses different strategies for each type - directly passing through ineffective areas while avoiding actual obstacles. This localized differentiation resolves the contradiction by maintaining reliability for real obstacles while improving productivity by not unnecessarily avoiding false-positive areas.
Solution Approach 2:
The patent segments the non-grass area concept into two distinct categories: ineffective areas (false positives from sensor detection) and actual obstacle areas. By segmenting the avoidance behavior accordingly - no avoidance for ineffective areas but active avoidance for actual obstacles - the system achieves both high reliability and productivity.
2Reliability
If the lawn mower follows a complex avoidance path around non-grass areas, then the mower protects itself from obstacles, but the mowing path becomes longer and less efficient
Solution Approach 1:
The patent applies local quality by differentiating between two types of non-grass areas: ineffective areas (where the sensor incorrectly identifies grass as non-grass) and actual obstacle areas. The mower uses different strategies for each type - directly passing through ineffective areas while avoiding actual obstacles. This localized differentiation resolves the contradiction by maintaining reliability for real obstacles while improving productivity by not unnecessarily avoiding false-positive areas.
Solution Approach 2:
The patent extracts the ineffective areas from the obstacle avoidance system by creating a separate category that is excluded from avoidance behavior. By taking out these false-positive areas from the general non-grass area category, the system eliminates unnecessary detours and time loss while maintaining protection against actual obstacles.
3Reliability
If the lawn mower avoids all non-grass areas, then the mower prevents damage, but the mowing coverage becomes incomplete in special areas like flagstone paths and manhole covers
Solution Approach 1:
The patent applies local quality by differentiating between two types of non-grass areas: ineffective areas (where the sensor incorrectly identifies grass as non-grass) and actual obstacle areas. The mower uses different strategies for each type - directly passing through ineffective areas while avoiding actual obstacles. This localized differentiation resolves the contradiction by maintaining reliability for real obstacles while improving productivity by not unnecessarily avoiding false-positive areas.

AI summary
The present disclosure provides a mowing control method, a setting method, a lawn mower, a setting apparatus and an electronic device. The mowing control method is applied to a lawn mower, and the lawn mower includes a first sensor, where the first sensor is a non-contact sensor, and the non-contact sensor is used to distinguish between a grass area and a non-grass area. The mowing control method includes: controlling the lawn mower to avoid the non-grass area to walk; receiving first position information of an ineffective area; when it is determined according to the first position information that the lawn mower walks to the ineffective area, controlling the lawn mower to pass and perform mowing within the ineffective area. Since there is no need to avoid the ineffective area, the walking path of the lawn mower is simpler, thereby improving the mowing efficiency of the lawn mower.
