Room Capacity Calculation Using Limit Distance Data
Solution Overview
Problem
Current room management systems do not account for the distance between individuals, making them inadequate for preventing the spread of infection during disasters like pandemics.
Innovation Solution
A room management system that calculates the number of allowable users based on a defined limit distance, ensuring sufficient space between persons by using data acquisition and calculation units to determine the maximum number of users that can occupy a room while maintaining social distancing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the number of users in a room is increased to maintain business operations, then productivity is improved, but the risk of infection spread increases due to insufficient distance between persons
Solution Approach 1:
The patent changes the parameter of user capacity calculation from traditional furniture-based limits to distance-based limits. By using limit distance data (e.g., 2 meters) to calculate the maximum number of allowable users, the system dynamically adjusts room capacity to maintain social distancing while enabling business operations. This resolves the contradiction by allowing maximum productivity within safe distance constraints.
2Device complexity
If traditional room management methods are used that only consider furniture and obstacles, then device complexity is reduced, but measurement precision of safe capacity is insufficient for infection prevention
Solution Approach 1:
The patent enhances the room management system by integrating multiple functions: acquiring room data (furniture, obstacles), acquiring limit distance data (infection prevention parameter), calculating allowable users based on both, and notifying users of the result. This multi-functional approach maintains system universality while improving measurement precision for infection-prone scenarios without requiring entirely new complex systems.

AI summary
A number-of-allowable-users calculation unit (212) calculates, as the number of allowable users of a room, the number of persons with which a distance equal to or greater than a limit distance can be secured in the room, based on limit distance data indicating the limit distance defined as a distance to be kept between persons and room data indicating information on the room to be used by one or more persons.
