Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle air distribution systems are inefficient due to high energy consumption, significant mechanical parts, and aerodynamic resistance, which limits airflow and requires complex adjustments to direct air effectively.
Innovation Solution
An air distribution system with adjustable air blades and nozzles that create turbulence to enhance airflow, reduce noise, and minimize mechanical parts, allowing for independent air flow direction and increased air speed, while maintaining or reducing the size of the heater blower unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional air vents with horizontal and vertical slats are used to distribute air, then air flow direction can be adjusted, but the device complexity increases due to many mechanical parts
Solution Approach 1:
The patent extracts and removes the complex mechanical adjustment mechanism from the air vent system. Instead of using traditional horizontal and vertical slats with motors and linkages, the invention uses a simple adjustable air blade that can be positioned by the user without any mechanical adjustment mechanism, thereby eliminating the complex mechanical parts while retaining air flow direction control capability
Solution Approach 2:
The patent inverts the conventional approach by using a single adjustable air blade instead of multiple fixed slats. The air blade can be manually positioned to different angles to control air flow direction, replacing the need for complex mechanical adjustment mechanisms with a simple, direct user-adjustable component
2Device complexity
If conventional air vents with fixed direction are used, then device complexity is reduced, but air flow efficiency decreases
Solution Approach 1:
The patent applies dynamics by making the air blade adjustable rather than fixed. The air blade can be dynamically positioned by the user to optimize air flow direction for different operating conditions (defrosting, cooling, heating), thereby improving air flow efficiency without requiring complex mechanical adjustment mechanisms
3Volume of moving object
If heater blower unit size is reduced to decrease vehicle size, then air flow volume may be insufficient for defrosting and climate control
Solution Approach 1:
The patent changes the aerodynamic parameters of the air vent system by using an air blade design that optimizes air flow through the vent. This improves the efficiency of air utilization, allowing a smaller blower unit to achieve the same effective air flow volume by reducing aerodynamic resistance and improving air distribution
4Productivity
If cylindrical air vent shape is used to maximize air flow, then air flow volume increases, but design flexibility is reduced
Solution Approach 1:
The patent segments the air vent opening into multiple sections around the central air blade. This allows the air vent to have a non-cylindrical shape that fits various dashboard designs while the air blade itself maintains an aerodynamic form that maximizes air flow through the vent
