Solution Overview

Problem

Existing air conditioning systems face issues with poor selectivity in air supply, increased power consumption, and reduced service life due to the simultaneous handling of heat exchange and additional air handling functions, which cannot be easily customized or modified to meet user needs.

Innovation Solution

The air conditioning system supplies heat exchange air from the upper portion and air handled by an air handling module, such as a humidification or purification module, from the lower portion, allowing for individual control and modular replacement to enhance selectivity and reduce unnecessary component usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If additional air handling modules are added to the original air duct, then humidification and purification functions are achieved, but heat exchange air and air handled by additional modules cannot be supplied separately, leading to increased power consumption

Engineering Contradiction:
Improveair handling functionsVSAvoidpower consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The air outlet is divided into an upper air outlet and a lower air outlet, allowing heat exchange air and air handled by additional modules to be supplied separately through different outlets, enabling independent control and reducing unnecessary energy consumption

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A control module is introduced as an intermediary to receive user input and control the opening and closing of the upper and lower air outlets, enabling selective air supply based on actual needs and optimizing energy usage

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If additional air handling modules are added to achieve humidification and purification, then air handling functions are enhanced, but the structure becomes more complex and requires additional research and development costs

Engineering Contradiction:
Improveair handling functionsVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The air outlet is segmented into upper and lower outlets with independent control, allowing different air handling functions to be delivered through different outlets without requiring complex structural modifications to integrate multiple functions into a single system

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The lower air outlet serves as a universal outlet that can supply air handled by various additional air handling modules (humidification, purification, etc.), allowing the system to perform multiple functions through a simple structural design

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

3Adaptability or versatility

If additional air handling modules are installed in the original air duct, then humidification and purification functions are added, but the original air conditioning performance is affected and coordination and matching require significant design effort

Engineering Contradiction:
Improveair handling functionsVSAvoidair conditioning performance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

By segmenting the air outlet into upper and lower outlets, the patent separates the air supply paths for heat exchange and additional air handling functions, allowing each path to operate independently without interfering with the other, thus maintaining original air conditioning performance while adding new functions

Inventive Principle:
Principle #1Segmentation

AI summary

Disclosed is an air supply method for an air conditioner, wherein the air conditioner selectively supplies first handled air from the middle upper portion and/or second handled air from the middle lower portion. By means of selectively supplying the first handled air from the middle upper portion and/or the second handled air from the middle lower portion, the two parts of the handled air can be controlled separately, not only improving the selectivity of the air supply and reducing the power consumption of the air conditioner, but also avoiding the decline in service life of the various components of the air conditioner due to unnecessary use.
