Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices, such as robots, operate inefficiently in water due to random movement and lack of mapping and positioning functions, leading to low efficiency in performing specific tasks.
Innovation Solution
A cleaning device equipped with detection units and a control method that allows it to determine a starting point, move along the edge of a water region, maintain a preset distance from the wall, and construct a map of the water region using position and obstacle detection data, enabling efficient path planning and obstacle avoidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cleaning device moves randomly without mapping and positioning functions, then the device complexity is reduced, but the operating efficiency deteriorates
Solution Approach 1:
The cleaning device performs preliminary mapping of the water region before cleaning operations. The control unit constructs a map of the water region by processing detection data from detection units, enabling the device to plan cleaning paths in advance rather than moving randomly, thus improving operating efficiency without requiring complex real-time decision-making hardware
Solution Approach 2:
The cleaning device uses detection units to continuously gather information about the water region and obstacles, feeds this data back to the control unit, and adjusts its movement path accordingly. This feedback mechanism enables efficient navigation and obstacle avoidance using relatively simple control logic, resolving the contradiction between efficiency and complexity
2Measurement precision
If the cleaning device equips multiple detection units and mapping functions, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The detection units serve multiple functions: they detect obstacles, map the water region boundaries, and provide positioning information. The control unit processes detection data from multiple units to construct a comprehensive map, achieving high measurement precision through multi-functional sensors rather than specialized equipment for each function, thus limiting the increase in device complexity
Solution Approach 2:
The patent combines multiple detection units (front detection unit, side detection unit, and position detection unit) into a unified detection system managed by a single control unit. This merging approach achieves comprehensive mapping precision while avoiding the complexity of multiple independent systems, as the control unit integrates data from all sensors to construct the water region map
