Solution Overview
Problem
Existing houses do not adequately address micro-droplet infection, which is a significant mode of transmission for infectious diseases, as aerosolized viruses can linger in the air and spread throughout living spaces.
Innovation Solution
A house design incorporating specific ventilation systems with total heat exchange, fans, and air cleaners to control airflow and suppress the spread of micro-droplets, ensuring air quality and energy efficiency while isolating infected individuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple margin space with a sliding door is used for isolation, then the structure is simple and easy to implement, but it cannot effectively suppress micro-droplet spread to other areas
Solution Approach 1:
The house is divided into multiple isolated chambers (habitability room, front chamber, passage) with controlled airflows between them. Each chamber has dedicated supply and exhaust ventilation, creating segmented air zones that prevent micro-droplet propagation while maintaining functional isolation capabilities.
Solution Approach 2:
A front chamber is introduced as an intermediary space between the habitability room and the passage. This intermediate chamber with its own ventilation system acts as a buffer zone, preventing direct air exchange and micro-droplet transmission between the infected person's room and public areas.
2Object-affected harmful factors
If ventilation systems supply air to multiple habitable rooms, then air quality is improved across the house, but energy consumption increases
Solution Approach 1:
The ventilation system recovers energy from exhaust air by performing total heat exchange with supply air. This heat recovery mechanism captures thermal energy that would otherwise be discarded, pre-heating or pre-cooling fresh air before it enters habitable rooms, thereby reducing the energy required for temperature conditioning while maintaining continuous air quality improvement.
3Loss of energy
If total heat exchange is performed in the ventilation system, then energy efficiency is improved, but the system complexity increases
Solution Approach 1:
The ventilation system combines multiple functions into a single integrated unit: air supply, exhaust, total heat exchange, and micro-droplet suppression all occur within one coordinated system. By merging these functions, the patent achieves energy efficiency through heat recovery while avoiding the complexity of multiple separate systems operating independently.
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
The design effectively contains micro-droplets within designated areas, maintains air quality, and conserves energy by using ventilation systems and air cleaners, providing a safe environment for both infected and non-infected residents.
Implementation Method 1
a first ventilation system configured to supply air from an outside of the house to the first habitable room and to exhaust air from the front chamber to the outside of the house
Implementation Method 2
a first fan configured to exhaust air from the first habitable room to the outside of the house
Implementation Method 3
a first door configured to open and close the first doorway
Implementation Method 4
an air cleaner installed in the third habitable room and configured to control an airflow amount in accordance with a number of people in the third habitable room

AI summary
A house taking measures against micro-droplet infection. The house includes a corridor, a front chamber leading to the corridor, a habitable room leading to the front chamber, a ventilation system that supplies air from the outside of the house to the habitable room and exhausts air from the front chamber to the outside of the house, and a fan that exhausts air from the habitable room to the outside of the house.
