Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mowing technologies face inefficiencies in covering complex and narrow areas due to frequent direction changes, especially when using non-random path planning, leading to prolonged operation times and reduced efficiency.
Innovation Solution
The method involves dividing the mowing area into convex sub-areas and determining the main extension direction of each sub-area as the mowing direction, reducing the frequency of direction changes and optimizing the mower path to improve efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If non-random path planning is used in complete coverage path planning, then working coverage and efficiency are improved, but in narrow and complex areas, frequent direction changes are still required, leading to increased operation time and reduced efficiency
Solution Approach 1:
The patent divides the mowing area into multiple sub-areas based on width characteristics. By segmenting the overall path planning into region-specific sub-plans, the system can apply different strategies to different areas, reducing frequent direction changes in narrow regions while maintaining efficient coverage in wider areas.
Solution Approach 2:
The patent implements local optimization by generating different path planning strategies for different sub-areas. Wide areas use one planning approach while narrow areas use another, allowing the system to adapt to local geometric characteristics and minimize direction changes in problematic regions.
2Reliability
If the mower operates in narrow areas with conventional path planning, then complete coverage is achieved, but the frequency of direction changes increases, reducing working efficiency
Solution Approach 1:
The patent segments the mowing area into sub-areas with different width characteristics. By identifying narrow regions and applying specialized path planning to these segments, the system maintains complete coverage while reducing unnecessary direction changes specific to narrow geometry.
Solution Approach 2:
The patent dynamically adjusts path planning based on local area characteristics. The system evaluates width at different positions and adapts the planning strategy accordingly, switching between different path generation methods to optimize for both coverage and efficiency in varying geometric conditions.
