Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle air conditioners have limitations in effectively distributing air to both the driver's and passenger's seats, with blocked discharge ports and inadequate automatic adjustment of air volume and temperature, leading to discomfort.
Innovation Solution
A multi-air mode apparatus and method for vehicle air conditioners that includes additional air discharge units and a control system to distribute air through multiple ducts and adjust air volume based on internal conditions, ensuring comfortable environments by providing wind through various discharge units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional air vent discharge ports are used (left side, right side, and central), then the air conditioner structure is simple, but the air distribution to driver and passenger seats is insufficient due to blocked discharge ports
Solution Approach 1:
The patent divides the air discharge function into multiple independent discharge units: traditional air vents and additional multi-air discharge units positioned at different locations (right side of driver seat, center in front of passenger seat). Each discharge unit operates independently to deliver air to specific seating areas, resolving the insufficiency of traditional blocked discharge ports while maintaining structural simplicity through modular addition.
2Adaptability or versatility
If fixed air discharge units are used, then the device structure is simple, but the air volume intensity cannot be automatically adjusted according to temperature changes and comfort requirements
Solution Approach 1:
The patent implements a control system that receives feedback from temperature sensors and user comfort settings, then automatically adjusts the air volume intensity of the multi-air discharge units. The controller modulates the blower motor speed and discharge port openings based on real-time temperature data and predefined comfort algorithms, enabling automatic adaptation to changing environmental conditions without requiring manual intervention.
3Ease of operation
If additional multi-air discharge units are added to improve air distribution, then air comfort is enhanced, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent designs the multi-air discharge units to serve multiple functions: they provide both cooling and heating air distribution, integrate with existing air duct systems, and can operate in conjunction with traditional air vents or independently. The discharge units use standard automotive materials and mounting methods, allowing them to be manufactured using existing production lines and integrated into various vehicle models without requiring entirely new manufacturing processes.

AI summary
A method of controlling an apparatus of multi-air mode for an air conditioner of a vehicle includes turning on power to the air conditioner, by a driver using an air conditioner operation unit provided in the vehicle. The method includes: determining, by a controller, whether a driver has turned on a multi-air mode through the air conditioner operation unit; in response to determining that the multi-air mode is turned on, operating, by the controller, the air conditioner in the multi-air mode; determining, by the controller, whether an intensity of air discharged from the air conditioner is greater than or equal to a first stage; and in response to determining that the intensity of air discharged from the air conditioner is greater than or equal to the first stage, automatically adjusting, by the controller, the intensity of the air to a second stage less than the first stage.
