Vehicle Air Conditioning System with Individualized Occupant Temperature Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle air conditioning systems fail to customize temperature settings for individual occupants, leading to discomfort and inconvenience, as they maintain a centralized temperature regardless of occupant preferences.
Innovation Solution
A system that measures each occupant's body temperature using non-contact sensors, determines personalized cooling or heating services, and controls the air conditioner accordingly, incorporating voice analysis and health state monitoring to provide tailored climate control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a centralized air conditioning system is used to maintain a uniform interior temperature, then the system structure is simple and energy consumption is reduced, but individual occupant comfort requirements cannot be satisfied
Solution Approach 1:
The air conditioning system is divided into multiple independent control zones corresponding to different seating positions. Each zone has its own temperature control capabilities, allowing individual occupants to adjust their local environment without affecting other zones. This segmentation enables personalized temperature control while maintaining a manageable system architecture.
Solution Approach 2:
The system implements different temperature settings and control parameters for different spatial locations within the vehicle. Each seating position can have customized temperature preferences, airflow directions, and heating/cooling intensities tailored to the specific needs and preferences of occupants in that location.
2Ease of operation
If manual temperature adjustment is required for each occupant, then individual comfort can be improved, but operational convenience deteriorates due to repeated adjustments
Solution Approach 1:
The system automatically detects occupant presence, measures body temperature using non-contact sensors, and adjusts temperature settings without requiring manual intervention. The air conditioning system serves itself by making intelligent decisions based on sensor data, eliminating the need for occupants to repeatedly adjust controls.
Solution Approach 2:
The system continuously monitors occupant body temperature and comfort conditions through sensors, and automatically adjusts temperature settings based on this feedback. This closed-loop control ensures that temperature adjustments are made proactively rather than reactively, reducing the need for manual intervention.
3Reliability
If body temperature measurement and health monitoring are added to provide personalized service, then occupant comfort and health care are improved, but device complexity and measurement requirements increase
Solution Approach 1:
The system replaces contact-based temperature measurement methods with non-contact infrared or optical sensing technologies. This substitution eliminates the need for physical contact with occupants, simplifies the measurement process, and enables automated detection of body temperature for health monitoring purposes.
Solution Approach 2:
The sensing system is designed to perform multiple functions simultaneously: detecting occupant presence, measuring body temperature, monitoring health conditions, and guiding air conditioning control decisions. This multi-functionality reduces the need for separate dedicated sensors and systems for each function.

AI summary
A system and method for controlling an air conditioner to provide cooling or heating customized to each occupant of a vehicle by measuring body temperatures of each occupant. The system includes a body temperature measuring unit configured to measure a body temperature of each occupant, a personalized service determining unit configured to determine a personalized service including whether to drive a cooling device or a heating device for each occupant based on the body temperature of each occupant, and an air conditioner controlling unit configured to control the air conditioner discriminatively for each occupant based on a personalized service.
