Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current autonomous robotic refuse container systems lack efficient methods for self-replacement and coordination, leading to potential malfunctions, full bins, and battery depletion, which can disrupt their operation and require manual intervention.
Innovation Solution
A method where processors of robotic refuse containers communicate to request and coordinate replacements based on factors like battery charge, fill volume, and location, using a control system to instruct navigation to charging stations or collection sites, and employing Markov Decision Processes to optimize replacement decisions.

Engineering Contradiction Analysis
1Extent of automation
If autonomous robotic refuse containers operate independently without coordination, then each container can function autonomously, but system reliability deteriorates due to potential malfunctions, full bins, and battery depletion
Solution Approach 1:
The patent combines multiple robotic refuse containers into a coordinated fleet managed by a central control system. The control system integrates information from multiple containers regarding battery levels, fill volumes, and locations, enabling collective decision-making that improves overall system reliability while maintaining individual container autonomy for execution of tasks.
Solution Approach 2:
The system implements continuous feedback loops where robotic containers report their status (battery charge, refuse volume, location) to the control system, which processes this information and sends replacement instructions. This feedback mechanism ensures that containers are proactively replaced before malfunctions occur, maintaining high system reliability.
2Device complexity
If manual intervention is used to replace robotic refuse containers, then system complexity is reduced, but productivity deteriorates due to disruption of operation and time consumption
Solution Approach 1:
The robotic refuse containers are equipped with autonomous capabilities to request replacements when needed. The control system automatically processes these requests, selects appropriate replacement containers from the fleet, and coordinates navigation without human intervention. This self-service mechanism maintains operational continuity while managing system complexity through automation.
Solution Approach 2:
The system maintains a fleet of standby robotic containers that are pre-charged and ready for deployment. When a container needs replacement, a pre-prepared replacement unit is already available, eliminating wait time and ensuring continuous operation without requiring manual intervention to prepare replacements.
3Loss of information
If robotic refuse containers do not coordinate replacements, then communication requirements are minimized, but loss of time increases due to inefficient replacement decisions
Solution Approach 1:
Containers continuously communicate their status (battery level, refuse volume, location) to the control system, which processes this feedback information to make optimal replacement decisions. This structured communication minimizes information loss while enabling efficient, data-driven replacement timing that reduces overall system downtime.
Solution Approach 2:
The control system monitors multiple parameters simultaneously (battery charge thresholds, refuse volume thresholds, container locations) and uses changes in these parameters to trigger replacement decisions. By tracking multiple parameters, the system makes comprehensive replacement decisions efficiently without requiring excessive communication overhead.
