Moveable air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional movable air conditioners are unable to accurately cool or heat specific regions where people are present, leading to inefficient energy consumption and discomfort due to the discharge of waste air towards individuals.
Innovation Solution
A movable air conditioner equipped with a human body recognition unit using infrared image sensors to detect and track individuals, adjusting its position and air discharge direction to provide targeted cooling or heating while preventing waste air from being directed at people.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the air conditioner moves toward the air conditioning load, then the cooling or heating can be localized to specific regions, but the air conditioner may move toward wrong locations (such as windows or doors) and cool or heat unnecessary regions
Solution Approach 1:
The patent applies feedback by using a human body detection unit to continuously monitor and provide information about person locations to the control unit. The control unit adjusts the air conditioner's movement and air discharge based on real-time detection feedback, ensuring the unit moves toward correct locations where people are present rather than simply toward high air conditioning load areas like windows or doors.
Solution Approach 2:
The air conditioner performs self-service by automatically detecting human bodies and autonomously adjusting its position and air discharge direction without manual intervention. The control unit processes detection information and independently decides movement and air discharge strategies, enabling the system to serve itself in locating and cooling/heating the correct regions.
2Device complexity
If the air conditioner discharges air in fixed directions, then the structure is simple, but dead zones are generated where air blowing amount is remarkably low
Solution Approach 1:
The patent applies dynamics by making the air discharge direction changeable rather than fixed. The air discharge unit can adjust its discharge direction dynamically based on the detected position of human bodies, allowing the air conditioner to effectively cover different regions and eliminate dead zones while maintaining relatively simple structure.
3Productivity
If the air conditioner moves toward high air conditioning load areas, then it responds to thermal load requirements, but waste air may be discharged toward people causing discomfort
Solution Approach 1:
The control unit uses feedback from the human body detection unit to determine the relative positions of people and the air conditioner. Based on this feedback, the control unit adjusts the air discharge direction to avoid directing waste air toward detected human bodies, thereby eliminating discomfort while maintaining effective air conditioning response.
Solution Approach 2:
The system performs preliminary anti-action by proactively detecting human body positions before waste air discharge occurs and pre-adjusting the air discharge direction to prevent waste air from reaching people. This anticipatory adjustment avoids the harmful effect before it can occur.

AI summary
A movable air conditioner includes an air conditioner main body, an air conditioning unit installed in the air conditioner main body and configured to generate a cold air or a warm air, a moving unit configured to move the air conditioner main body, a control unit configured to control the air conditioning unit and the moving unit, and a human body recognition unit configured to recognize a person existing in a specific space. The control unit is configured to control the moving unit so that the air conditioner main body is moved toward the person recognized by the human body recognition unit so as to supply the cold air or the warm air from the air conditioning unit to the person recognized by the human body recognition unit.
