Solution Overview
Problem
Existing driving robot apparatuses face challenges in efficiently determining the water content of cleaning pads and adjusting their traveling paths accordingly, which affects cleaning performance and efficiency.
Innovation Solution
The driving robot apparatus employs a sensor to obtain load values of a rotary motor while rotating a holder with a cleaning pad, using instantaneous and average load values, standard deviations, and reference values to control water supply and adjust its path based on the water content and docking station protrusions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the driving robot apparatus uses a sensor to obtain load values of the rotary motor, then the water content identification precision is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical water content detection mechanisms with an electrical sensing approach. The sensor detects load values of the rotary motor, and water content is identified through processing these electrical signals and comparing them with reference values, thereby improving measurement precision while avoiding complex mechanical structures.
Solution Approach 2:
The patent introduces load value as an intermediary parameter between the cleaning pad's water content and the sensor detection. Instead of directly detecting water content, the sensor measures the motor's load value, which is then processed to infer water content, simplifying the detection system while maintaining precision.
2Reliability
If the driving robot apparatus controls water supply based on instantaneous and average load values, then the cleaning performance is improved, but the control complexity increases
Solution Approach 1:
The patent implements a feedback control system where the sensor continuously monitors load values, and the controller adjusts water supply based on comparisons between instantaneous load values, average load values, and reference values. This closed-loop feedback mechanism ensures optimal cleaning performance by dynamically adjusting water supply to match actual cleaning needs.
Solution Approach 2:
The patent uses a simplified control approach by comparing load values against predetermined reference values rather than implementing complex adaptive algorithms. This partial action approach provides sufficient cleaning performance for typical conditions while keeping the control system simple and easy to implement.
3Productivity
If the driving robot apparatus adjusts traveling path based on water content identification, then the cleaning efficiency is improved, but the path planning complexity increases
Solution Approach 1:
The patent performs water content identification and path adjustment decisions in advance during the cleaning process. By continuously monitoring load values and identifying water content early, the system can proactively adjust the traveling path to optimize cleaning efficiency, such as returning to areas that need re-cleaning, rather than reacting to cleaning quality issues later.
