Solution Overview
Problem
Existing airflow guiding systems for vehicles face inefficiencies in using front air for both cooling engines and improving aerodynamic performance, often leading to increased interior temperatures and reduced aerodynamic efficiency when air flow to the engine compartment is stopped.
Innovation Solution
An airflow guiding system that includes ambient air intakes, engine compartment air holes, main ducts, and independently operable air flaps to selectively direct air to the engine compartment or front wheels, with auxiliary ducts ensuring continuous air flow to the front wheels, enhancing air use efficiency and aerodynamic performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air flow to the engine compartment is stopped to improve aerodynamic performance, then aerodynamic performance is improved, but interior of the engine compartment becomes overheated
Solution Approach 1:
The airflow guiding system segments the air intake paths into multiple independent channels: front air holes for engine compartment cooling, side air holes for wheel well cooling, and auxiliary air holes for additional cooling capacity. Each channel can be independently controlled by corresponding air flaps, allowing selective opening/closing to balance aerodynamic performance with cooling requirements.
Solution Approach 2:
The system employs dynamically controllable air flaps that can adjust airflow paths in real-time based on operating conditions. The air flaps are actuated by motors or actuators that respond to temperature sensors and control units, enabling the system to transition between different airflow configurations - fully open for maximum cooling, partially open for balanced operation, or fully closed for optimal aerodynamics when cooling is not required.
2Temperature
If air passes through the radiator grill and air flap to cool the engine, then engine cooling is improved, but use efficiency of air in front of vehicle body decreases
Solution Approach 1:
The airflow guiding system enables ambient air to serve multiple functions through different pathways. Air entering through the front air holes can be directed to the engine compartment for cooling, while air through side air holes cools the wheel wells. The same ambient air source thus performs multiple cooling tasks, improving overall air use efficiency while maintaining effective engine cooling when needed.
Solution Approach 2:
The system applies different airflow qualities and paths to different local areas requiring cooling. Engine compartment air holes are positioned and sized specifically for engine cooling needs, while side air holes are optimized for wheel well cooling. This localized approach ensures each region receives appropriate airflow without wasting ambient air on areas that don't require cooling.
3Device complexity
If a single air flap controls both engine compartment air holes and main ducts, then device complexity is reduced, but adaptability to different cooling requirements decreases
Solution Approach 1:
The control system is segmented into multiple independent air flaps - a first air flap for engine compartment air holes and a second air flap for side air holes. Each flap can be independently actuated by separate motors or actuators, allowing the control unit to adjust each airflow path according to specific cooling requirements without being constrained by a single unified control mechanism.
