Solution Overview

Problem

Existing ventilation systems fail to adequately address non-uniform air conditioning states such as temperature, humidity, and air quality across multiple spaces in a building, leading to user discomfort when moving between spaces.

Innovation Solution

A ventilation system comprising a ventilator with a heat exchange element, an air conveyor with a dust collector, and a controller that determines air conveyance based on temperature and gas concentration measurements between spaces to maintain comfort levels, using sensors to control operations and ensure consistent air quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If air conditioning is performed independently in each room using separate air conditioners, then each room can be air-conditioned individually, but the non-uniformity of air conditioning state between rooms cannot be sufficiently alleviated

Engineering Contradiction:
Improveindividual air conditioning capabilityVSAvoiduniformity of air conditioning state
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent merges the air conditioning functions of multiple rooms into a single centralized air conditioning unit that serves multiple spaces. The main body of the air conditioner is configured to condition air that is then distributed to multiple rooms through air supply ports, creating uniform air conditioning states across different rooms while maintaining individual controllability through the controller.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If a centralized air conditioning system is used to uniform air conditioning states, then user comfort is improved, but the system complexity increases

Engineering Contradiction:
Improveuniformity of air conditioning stateVSAvoidsystem structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The air conditioner is designed with multi-functionality to serve multiple rooms simultaneously. The single main body unit performs air conditioning for multiple spaces through multiple air supply ports, reducing the need for multiple separate air conditioners while maintaining uniform air conditioning states across all served rooms.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The controller acts as an intermediary between the sensor that detects air conditioning states and the air conditioning mechanism. The controller receives temperature information from the sensor and adjusts the air conditioning operation accordingly, enabling automatic maintenance of uniform air conditioning states without requiring complex manual control systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Use of energy by moving object

If air conditioning is optimized for each room independently, then energy efficiency per room may be improved, but overall energy consumption increases due to multiple units

Engineering Contradiction:
Improveenergy efficiency per roomVSAvoidtotal energy consumption
Core Design Contradiction:
Use of energy by moving objectVSUse of energy by stationary object

Solution Approach 1:

The patent combines multiple air conditioning functions into a single centralized unit, reducing the total number of compressors and refrigerant circulation systems needed. This merger reduces overall energy consumption while still providing individualized air conditioning control for multiple rooms through the controller's ability to manage air distribution to different spaces.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A ventilation system according to a certain aspect includes: a ventilator that ventilates a first space; an air conveyor that is installed on a ceiling surface of the first space and conveys air from the first space to a second space different from the first space; a controller that controls an operation of the ventilator and an operation of the air conveyor; a first temperature measurer that measures an air temperature of the first space; and a second temperature measurer that measures an air temperature of the second space. The controller includes a determiner that determines whether the air conveyance by the air conveyor is possible or impossible on the basis of an air temperature of the first space and an air temperature of the second space.
