AVN Terminal Biometric Air Conditioning Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current audio video navigation (AVN) terminals in vehicles lack the ability to dynamically control the air conditioning environment based on the biometric information and location of passengers, leading to inefficient temperature regulation and passenger comfort.
Innovation Solution
An AVN terminal system that includes a communication unit to receive signals from user terminals, an extracting unit to calculate location information using direction and distance data, and a controller to adjust the air conditioning environment based on user biometric information, allowing for personalized temperature settings for each seat in the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the AVN terminal uses a single uniform air conditioning setting for all seats, then the system complexity is low, but passenger comfort and adaptability deteriorate
Solution Approach 1:
The air conditioning control is segmented into multiple independent zones, one for each seat. Each seat has its own air conditioning controller that can be independently adjusted based on the passenger's biometric information, allowing personalized temperature control without requiring a completely new centralized system.
Solution Approach 2:
Each seat is equipped with local sensors and controllers that detect and adjust air conditioning parameters specific to that location. The biometric sensors are positioned near each seat to detect local passenger conditions, and the air conditioning outlets are localized to deliver conditioned air directly to each passenger's vicinity.
2Ease of operation
If the AVN terminal collects and processes biometric information from all passengers, then personalized comfort is improved, but the device complexity and information processing requirements increase
Solution Approach 1:
The system automatically detects biometric information from passengers and adjusts air conditioning settings without requiring manual input from passengers. The biometric sensors continuously monitor passenger conditions and the controller autonomously modifies temperature and airflow settings, eliminating the need for passengers to manually adjust controls.
Solution Approach 2:
The system implements a feedback loop where biometric sensors continuously monitor passenger physiological states and feed this information back to the air conditioning controller. The controller processes this feedback and dynamically adjusts air conditioning parameters to maintain optimal comfort conditions for each passenger.
3Adaptability or versatility
If the AVN terminal implements per-seat air conditioning control, then passenger comfort is improved, but energy consumption increases
Solution Approach 1:
The air conditioning system dynamically adjusts its operation based on real-time detection of passenger presence and biometric conditions. When a seat is occupied, the system activates localized air conditioning control for that seat; when unoccupied, it reduces or suspends operation for that zone, thereby adapting energy consumption to actual usage needs.
Solution Approach 2:
The system changes operational parameters such as temperature setpoints, airflow rates, and compressor speed based on detected passenger conditions. By adjusting these parameters dynamically rather than maintaining fixed high-performance settings, the system achieves personalized comfort while optimizing energy efficiency.
