Innovation Solution
An autonomous path treatment system comprising a mobile path recording device and an autonomous path treatment robot equipped with sensors and a controller, which captures path coordinates and directions, generates a path program, and autonomously treats the path using a treatment mechanism, reducing the need for manual labor and enhancing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual labor and traditional machinery are used for snow removal, then the method is simple to implement, but the productivity is low and labor costs are high
Solution Approach 1:
The autonomous path treatment robot performs snow clearing operations independently without human intervention. The robot navigates autonomously using GPS coordinates, activates treatment mechanisms based on sensor detection of snow conditions, and returns to charging stations automatically, enabling the system to service itself during operation.
Solution Approach 2:
The patent replaces manual mechanical snow removal with an autonomous robotic system that uses sensors, GPS navigation, and automated control systems. The robot substitutes human physical labor with automated mechanical and electronic systems including motorized propulsion, sensor arrays, and programmable logic controllers.
2Adaptability or versatility
If large vehicle plows are used for snow removal, then large areas can be cleared efficiently, but the vehicles cannot access narrow paths and areas with obstacles
Solution Approach 1:
The patent divides snow removal operations into segments based on path characteristics. Different treatment mechanisms are applied to different path types: plowing for open areas, blowing for narrow paths, and brushing for walkways. The autonomous robot can switch between these mechanisms depending on the detected path type and snow conditions.
Solution Approach 2:
The autonomous path treatment robot is designed with multiple treatment mechanisms (plow, blower, brush) that can be activated based on the path type and snow conditions. This multi-functional design allows a single robot to handle diverse clearing scenarios from wide driveways to narrow sidewalks, replacing the need for multiple specialized vehicles.
3Productivity
If manual shoveling is used for snow removal, then it can reach inaccessible areas, but it is the slowest and most expensive method
Solution Approach 1:
The autonomous path treatment robot performs snow clearing operations independently without human intervention. The robot navigates autonomously using GPS coordinates, activates treatment mechanisms based on sensor detection of snow conditions, and returns to charging stations automatically, enabling the system to service itself during operation.
Solution Approach 2:
The patent replaces manual mechanical snow removal with an autonomous robotic system that uses sensors, GPS navigation, and automated control systems. The robot substitutes human physical labor with automated mechanical and electronic systems including motorized propulsion, sensor arrays, and programmable logic controllers.
4Loss of time
If snow removal is performed during nighttime hours, then time constraints are met for Zero Tolerance Locations, but labor transportation and safety management become more difficult
Solution Approach 1:
The autonomous path treatment robot performs snow clearing operations independently without human intervention. The robot navigates autonomously using GPS coordinates, activates treatment mechanisms based on sensor detection of snow conditions, and returns to charging stations automatically, enabling the system to service itself during operation.
Solution Approach 2:
The patent replaces manual mechanical snow removal with an autonomous robotic system that uses sensors, GPS navigation, and automated control systems. The robot substitutes human physical labor with automated mechanical and electronic systems including motorized propulsion, sensor arrays, and programmable logic controllers.

AI summary
An autonomous path treatment system and associated path treatment method uses a mobile path recording device having a locator, a processor and firmware to capture a sequence of coordinates and directions of travel of a path as the mobile device is moved along the path and generate a path program file. The system also has an autonomous path treatment robot having: a treatment mechanism for treating the path; a controller having a processor and memory storing firmware that when executed obeys steps of the path program file to control the motor and the treatment mechanism to treat the path; and a server configured to execute a path program to process the captured sequence of coordinates and directions into the path program file containing instructions for controlling the autonomous path treatment robot to treat the path based upon the coordinates.
