Vehicle Air Conditioner Rear Console Duct Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air conditioners for vehicles with rear console ducts face decreased cooling efficiency in summer and heating efficiency in winter due to the inability to discharge conditioned-air through the rear console vent in foot mode, as the face and foot vents are blocked by a separation wall, preventing airflow between these vents.
Innovation Solution
An air controlling system with a door switching control unit that selectively opens and closes interacting passages between the face, foot, and rear console vents, allowing conditioned-air to be discharged through the rear console vent in foot mode by switching the rear console door to open the second interacting passage and close the first, thereby improving efficiency in all modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separation wall blocks the face and foot vents in foot mode, then the foot vent can be selectively opened, but the rear console vent cannot discharge conditioned-air decreasing cooling and heating efficiency
Solution Approach 1:
The air-conditioning case is divided into multiple independent vent systems (face vent, foot vent, rear console vent) with separate controlling doors. The rear console door is further segmented into a first door controlling the first interacting passage and a second door controlling the second interacting passage, allowing independent control of airflow paths to resolve the contradiction between selective operation and efficient productivity.
Solution Approach 2:
The rear console door acts as an intermediary mechanism between the foot door and the rear console vent. When the foot door opens, the rear console door mediates by opening the second interacting passage to connect the foot vent with the rear console vent, enabling conditioned-air discharge to rear seats without requiring direct connection between face and foot vents.
2Adaptability or versatility
If the rear console vent is connected only to the face vent through the first interacting passage, then the face mode works properly, but the foot mode cannot discharge conditioned-air to rear seats
Solution Approach 1:
The air-conditioning system employs dynamic reconfiguration of airflow passages through the rear console door mechanism. The first and second interacting passages are dynamically opened or closed based on the operating mode (face mode or foot mode), allowing the system to adapt its connectivity structure to meet different productivity requirements for conditioned-air discharge.
Solution Approach 2:
The rear console vent is designed with multi-functionality to serve both face mode and foot mode operations. Through the dual-passage system with controllable doors, the rear console vent can receive conditioned-air from either the face vent or the foot vent depending on the operating mode, making it a universal discharge point that maintains productivity across different operational scenarios.
