Vehicle Seat Air Conditioning Device with Separation Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioning devices for vehicle seats hinder seat mobility and transmit noise and vibration to passengers due to their configuration and installation.
Innovation Solution
An air conditioning device with a seat duct on the vehicle seat, a seat air conditioning unit on the lower frame, and a separation space between the seat and the frame, where air is discharged from the unit into the space and supplied to the duct, using a vapor compression refrigeration cycle mechanism with adjustable heat exchangers and blowers to prevent noise and vibration transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air conditioning unit is mounted on the seat, then the cooling/heating function is provided to the passenger, but the seat mobility is hindered
Solution Approach 1:
The air conditioning system is divided into separate components: the air conditioning unit is mounted on the lower frame while the seat remains independent, allowing the seat to move freely without being constrained by the air conditioning equipment
Solution Approach 2:
The air conditioning unit is extracted from the seat structure and relocated to the lower frame, separating the air conditioning function from the seat mobility function, thus eliminating the interference between the two
2Reliability
If the driving parts of the air conditioning device are mounted on the seat, then the air conditioning function is achieved, but noise and vibration are transmitted to the passenger
Solution Approach 1:
The driving parts of the air conditioning device are extracted from the seat structure and relocated to the lower frame, separating the noise and vibration sources from the passenger area, thus reducing the transmission of harmful factors to the passenger
Solution Approach 2:
The lower frame acts as an intermediary structure that carries the air conditioning unit and its driving parts, serving as a buffer that prevents direct transmission of noise and vibration to the seat and passenger
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
Enhances seat mobility while preventing noise and vibration from the air conditioning device's driving parts from reaching the passenger, ensuring effective cooling and heating without compromising seat movement or passenger comfort.
Implementation Method 1
a vapor compression refrigeration cycle mechanism having a refrigerant flow path passing through the first heat exchanger, the second heat exchanger, the compressor, and the expansion means
Implementation Method 2
a first heat exchanger operated as any one of an evaporator and a condenser, a second heat exchanger operated as the other one of the evaporator and a condenser
Implementation Method 3
a first air blower for flowing the air through the first heat exchanger; and a second air blower for flowing the air through the second heat exchanger

AI summary
The present disclosure relates to an air conditioning device for a vehicle seat; can include a seat duct formed on a seat of a vehicle, a seat air conditioning unit formed on a lower frame on which the seat is mounted, and a separation space interposed between the seat and the lower frame; and can be formed so that the air is discharged from the air conditioning unit into the separation space, and the air of the separation space is supplied to the seat duct. As a result, it is possible to enhance the mobility of the seat, and to prevent noise and vibration due to driving parts from being delivered to a passenger.
