Perpendicular Turn-Back Sweeping Method to Reduce Coverage Omissions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sweepers often miss areas during repeated cleaning due to mechanical repetition of the same sweeping path, leading to inefficient cleaning and a poor user experience, especially in larger areas where multiple cleanings are time-consuming and inconvenient.
Innovation Solution
A sweeping method and apparatus that performs first sweeping in a turn-back manner along a first direction and, based on a preset sweeping parameter fulfillment condition, performs second sweeping in a perpendicular direction, ensuring thorough coverage without repetition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the area to be swept is cleaned multiple times to achieve a certain degree of cleanliness, then the cleaning thoroughness is improved, but the time consumption increases
Solution Approach 1:
The patent applies dimensionality change by switching the sweeping direction from the first direction to a second direction that is perpendicular to the first direction. This allows the sweeper to cover areas that may have been missed during the first sweeping pass, thereby improving cleaning thoroughness without simply repeating the same path multiple times in the same direction, which would increase time consumption.
2Area of stationary object
If the sweeper mechanically repeats the same sweeping path multiple times, then the cleaning coverage is improved, but the omission of some places occurs
Solution Approach 1:
The patent solves the problem of omission by changing the sweeping dimension - switching from sweeping in the first direction to sweeping in the second perpendicular direction. This dimensional change ensures that areas potentially missed during the first pass are covered in the second pass, improving cleaning completeness while maintaining comprehensive coverage.
Solution Approach 2:
The patent implements dynamics by making the sweeping direction adjustable and changeable. The control unit determines whether to perform sweeping in the first direction or the second direction based on area characteristics, and can switch between directions as needed. This dynamic adjustment optimizes both coverage and completeness based on real-time conditions.
3Area of stationary object
If the area to be swept is large, then the cleaning capacity is improved, but the time required to clean once increases greatly
Solution Approach 1:
The patent applies segmentation by dividing the large area into different sweeping zones that can be covered in different directions. The control unit can determine to sweep in the first direction for one area and in the second perpendicular direction for another area, effectively segmenting the cleaning task to optimize time management across large spaces.
Solution Approach 2:
The patent uses dynamics by enabling the sweeper to adaptively adjust its sweeping direction based on the characteristics of different areas. For large areas, the system can dynamically switch between first direction sweeping and second direction sweeping, optimizing the cleaning path and reducing overall time consumption while maintaining comprehensive coverage.

AI summary
A sweeping method and apparatus, a sweeper, and a computer-readable medium are proposed. The sweeping method includes: performing first sweeping on an area to be swept in a turn-back manner along a first sweeping direction; and performing, based on a sweeping parameter fulfillment condition, second sweeping on the area to be swept in a turn-back manner along a second sweeping direction, where the second sweeping direction is perpendicular to the first sweeping direction.
