Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional supercharger systems face challenges in efficiently directing air, integrating compactly into standard vehicles without reconfiguring the hood, minimizing temperature increase and power consumption, and maximizing fuel efficiency, while often decreasing vehicle efficiency and not meeting CARB emissions requirements.
Innovation Solution
A supercharger system with a rotor assembly and interlaced cross-runner pattern, featuring a front drive, front inlet configuration, and inverted orientation, integrated into the intake manifold housing, which includes an ultra-low restriction inlet tube, integrated bypass valve, and electric throttle body, to provide improved airflow and reduced parasitic power loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a conventional supercharger system is installed, then engine power is increased, but parasitic power loss increases and fuel consumption decreases
Solution Approach 1:
The patent inverts the conventional supercharger orientation by positioning the inlet at the front and the outlet at the rear, opposite to traditional designs. This inversion allows the supercharger to be driven by the intake air flow itself rather than requiring a separate drive mechanism, thereby reducing parasitic power loss while maintaining power boosting capability
Solution Approach 2:
The supercharger system is designed to be self-driven by the pressure differential created during intake air flow. The front inlet captures ambient air pressure, and the rear outlet exhausts to atmospheric pressure, creating a natural flow that drives the rotor assembly without requiring additional engine power for operation
2Power
If a conventional supercharger system is installed, then engine power is increased, but temperature increase occurs
Solution Approach 1:
The inverted orientation with front inlet and rear outlet positions the air intake away from engine heat sources and directs airflow through a path that minimizes exposure to thermal radiation from exhaust manifolds and other hot engine components, thereby reducing intake air temperature increase
Solution Approach 2:
The patent extends the air flow path in the longitudinal dimension of the vehicle by positioning the inlet at the front and outlet at the rear, allowing air to travel through a longer, cooler path rather than being compressed in a compact space near hot engine components
3Stress or pressure
If a conventional supercharger system is installed, then air pressurization is achieved, but airflow restriction occurs
Solution Approach 1:
The inverted configuration with front inlet and rear outlet creates a more direct and less restricted airflow path compared to conventional orientations. The inlet tube is positioned to capture ambient air with minimal restriction, and the outlet is positioned to exhaust freely to atmospheric pressure, maximizing airflow efficiency while achieving necessary pressurization
Solution Approach 2:
The supercharger system is divided into distinct functional segments: a front inlet section for ambient air capture, a midsection rotor assembly for compression, and a rear outlet section for exhaust. This segmentation allows each section to be optimized for its specific function, with the inlet minimized for low restriction and the outlet positioned for free exhaust
4Power
If a conventional supercharger system is installed, then engine power is increased, but vehicle efficiency decreases
Solution Approach 1:
The supercharger is designed to operate using the energy already present in the intake air flow itself, rather than requiring additional engine power to drive it. The pressure differential between the front inlet and rear outlet naturally drives the rotor assembly, making the system self-sufficient and minimizing its impact on overall vehicle efficiency
Solution Approach 2:
The inverted orientation allows the supercharger to be positioned and operated in a manner that minimizes energy losses, with the inlet capturing ambient pressure and the outlet exhausting to atmospheric pressure, creating an efficient energy conversion process that boosts power while maintaining vehicle efficiency
