Vehicular Seat Surface Temperature Adjustment via Airflow Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for pre-air conditioning of vehicle cabins do not effectively adjust the surface temperature of vehicular seats to a comfortable level by the time an occupant sits, due to temperature differences between air-conditioning air and the cabin.
Innovation Solution
An on-board device comprising an air-conditioning unit, a seat moving unit, and a control unit that moves the vehicular seat closer to the air outlet port and reclines the seat back to ensure effective application of air-conditioning air, adjusting the seat's surface temperature to match the pre-air conditioning temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If pre-air conditioning is performed by blowing air-conditioning air into the vehicle cabin, then the air temperature in the cabin can be adjusted, but the surface temperature of the vehicular seat cannot be effectively adjusted to a comfortable level due to temperature differences between the air-conditioning air and the cabin
Solution Approach 1:
The seat is moved to the front side position in advance before the occupant enters the vehicle, so that the seat back surface is positioned to directly face the air outlet port. This preliminary positioning ensures that when air-conditioning air is blown, it directly contacts the seat back surface, effectively adjusting the seat surface temperature to a comfortable level before the occupant sits down.
Solution Approach 2:
The vehicular seat is made movable in the seat front-rear direction through a seat moving unit. By dynamically adjusting the seat position to the front side during pre-air conditioning operation, the system optimizes the contact between air-conditioning air and the seat back surface, thereby improving heat transfer efficiency and seat surface temperature adjustment effectiveness.
2Temperature
If the vehicular seat is moved to the seat front side during pre-air conditioning, then the seat can receive air-conditioning air directly and adjust surface temperature, but the seat position changes from its original position
Solution Approach 1:
The seat position is adjusted in advance before the occupant enters the vehicle. By moving the seat to the front side position during pre-air conditioning operation, the system optimizes heat transfer to the seat surface. After the occupant enters and normal air conditioning begins, the seat can be returned to its original position, so the position change is temporary and purpose-driven.
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 solution effectively adjusts the surface temperature of the vehicular seat to a comfortable level by positioning the seat to receive air-conditioning air directly, enhancing occupant comfort upon entering the vehicle.
Implementation Method 1
an air-conditioning unit configured to perform air conditioning by blowing air-conditioning air into a vehicle cabin
Implementation Method 2
the vehicular seat is brought close to the air outlet port before the occupant gets into the vehicle, and receives the air-conditioning air supplied by pre-air conditioning. Accordingly, the surface temperature of the vehicular seat at the time when the occupant sits on the seat is adjusted to be close to the temperature of the pre-air conditioning.
