Air cleaner including thermoelectric module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air cleaners are ineffective in isolated or small spaces, such as rooms or dining areas, and fail to provide adequate air purification at the height of human respiratory organs when placed on the floor, leading to health risks from particulate matter.
Innovation Solution
An air cleaner incorporating a thermoelectric module that generates conditioned air, is compact, and can be detachably coupled to furniture, using a single blowing fan to create airflow and integrate supply and heat dissipation channels, improving operation performance and user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional air cleaners are placed on the floor, then they can cover large areas, but air purification is weak at the height of human respiratory organs
Solution Approach 1:
The patent transitions the air cleaner from floor-level operation to desk-top operation, changing the vertical dimension of air delivery. The device supplies conditioned air at desk height (approximately 0.7-1.0m from floor) rather than floor level, directly targeting the respiratory zone of seated individuals and improving air purification effectiveness where people actually breathe.
2Temperature
If a thermoelectric module is added to generate conditioned air, then user comfort is improved, but device complexity increases
Solution Approach 1:
The patent combines the thermoelectric module with the existing fan and housing structures. The thermoelectric module integrates with the blower housing and utilizes the same air intake and discharge pathways as the fan, merging cooling functionality with the existing air circulation system rather than adding completely separate components.
Solution Approach 2:
The thermoelectric module serves multiple functions: it cools air for user comfort, and its heat dissipation side can be utilized for heating or ventilation purposes. The single module provides both cooling and potential heating capabilities, reducing the need for separate heating and cooling systems.
3Productivity
If separate fans are used for blowing and heat dissipation, then airflow control is improved, but noise and device complexity increase
Solution Approach 1:
The patent combines the blowing fan and heat dissipation fan into a single fan unit. The fan is positioned to simultaneously draw air through the thermoelectric module for cooling and expel heat from the heat dissipation channel, eliminating the need for separate motors and control systems while reducing noise and complexity.
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 air cleaner effectively provides conditioned air, reduces noise, enhances usability by being compact and quiet, and ensures reliable operation by separating supply and heat dissipation channels, while being easily attachable to furniture for improved coverage.
