Autonomous Sterilization System with Human Presence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sterilization methods, especially those involving stronger chemicals and UV radiation, pose health risks to humans and are not effective in maintaining proactive protection throughout the day, leading to downtime and reduced service availability in facilities like public transportation systems and schools.
Innovation Solution
The development of autonomous sterilization systems that utilize AI logic to determine when, where, and how sterilization should occur, incorporating sensors to detect human presence and selectively activate sterilization devices, allowing for safe and efficient sterilization without removing structures or vehicles from service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If stronger sterilization chemicals and UV radiation are used, then sterilization effectiveness is improved, but health risks to humans increase
Solution Approach 1:
The patent introduces an intermediary control system consisting of sensors, processors, and controllers that mediate between the sterilization devices and human presence. The system detects human presence through sensors and controls sterilization device activation accordingly, allowing strong sterilization methods to be used only when safe, thus resolving the contradiction between sterilization effectiveness and human safety
Solution Approach 2:
The sterilization system performs self-monitoring and self-regulation by automatically detecting human presence and controlling its own operation. The system serves itself by making intelligent decisions about when to activate sterilization based on real-time environmental conditions, eliminating the need for manual intervention while ensuring safety
2Reliability
If offline sterilization processes are implemented, then sterilization thoroughness is improved, but service availability decreases
Solution Approach 1:
The patent transforms the static offline sterilization process into a dynamic system that can operate in multiple modes. The system adapts its behavior based on real-time conditions, enabling thorough sterilization during appropriate times while maintaining service availability during operational periods through selective activation of sterilization devices
Solution Approach 2:
The system enables continuous sterilization capability by activating sterilization devices during service hours when safe, eliminating the need to close facilities for overnight sterilization. This continuous action maintains both thoroughness and availability, resolving the contradiction between sterilization completeness and service productivity
3Reliability
If sterilization is performed frequently, then protection level is improved, but operational disruption increases
Solution Approach 1:
The system implements periodic sterilization cycles triggered by specific conditions such as vehicle arrival at destinations, passenger unloading, or time-based intervals. This periodic action maintains high protection levels through frequent sterilization while minimizing operational disruption by coordinating with natural service cycles rather than imposing arbitrary shutdowns
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
These systems enable facilities to remain open and available for longer periods, reducing costs and increasing service levels by allowing for more frequent and targeted sterilization processes, thereby decreasing exposure probabilities for users.
