Terminal Sanitization via Droplet Position Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for detecting and sanitizing contaminated areas on terminals, such as those used in immigration inspection, are inadequate in identifying and effectively sanitizing parts that come into contact with saliva droplets, which can spread infectious diseases.
Innovation Solution
An information processing system that includes a terminal with a detection unit to identify contact positions and droplet attachment points, and a sanitization part identification unit to determine which parts need sanitization, using a combination of cameras, touch panels, weight sensors, and temperature sensors to accurately detect contact and droplet positions for effective sanitization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual sanitization methods are used, then sanitization can be performed, but the effectiveness is reduced due to inability to accurately identify droplet contamination areas
Solution Approach 1:
The patent replaces manual visual inspection and manual sanitization with an automated detection system using cameras and sensors. The camera captures images of the terminal surface, and the detection unit automatically identifies droplet positions, eliminating the need for manual inspection and improving both detection accuracy and sanitization reliability.
Solution Approach 2:
The patent introduces a camera and detection unit as an intermediary between the droplets and the sanitization process. This intermediary detects droplet positions and transmits information to the sanitization control unit, enabling precise identification of contamination areas that would be difficult to detect manually.
2Reliability
If the entire terminal is sanitized, then all contaminated areas are covered, but time and resources are wasted on non-contaminated areas
Solution Approach 1:
The patent applies sanitization locally only to detected droplet positions rather than uniformly across the entire terminal. The sanitization control unit receives coordinates from the detection unit and directs sanitization resources precisely to contaminated areas, improving completeness while reducing time and resource waste.
Solution Approach 2:
The patent performs preliminary detection of droplet positions before sanitization. The camera and detection unit identify contamination areas in advance, allowing the sanitization process to be targeted and efficient, rather than sanitizing the entire terminal without prior knowledge of where contamination exists.
3Measurement precision
If multiple detection methods are combined, then detection accuracy improves, but system complexity increases
Solution Approach 1:
The patent uses a camera system that serves multiple functions: capturing images for droplet detection, analyzing contact positions, and providing visual feedback. This multi-functional approach improves detection accuracy without proportionally increasing system complexity, as a single camera system performs multiple detection tasks.
Solution Approach 2:
The patent combines image processing algorithms and detection methods into a unified detection unit. Rather than using separate independent systems for different detection tasks, the patent integrates multiple detection functions into a single coordinated system, improving accuracy while managing complexity through consolidation.

AI summary
An information processing system includes: a terminal used by a user; a detection unit that detects at least one of a position of contact by the user and a position in which droplets of saliva of the user are attached, in the terminal; and an identification unit that identifies a sanitization part to be sanitized of the terminal, on the basis of the at least one of the positions. According to such an information processing system, it is possible to properly identify the part to be sanitized in an operation terminal.
