Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing superchargers face inefficiencies due to complex and large actuator systems required for adjusting compressor inlet cross sections, which can lead to compressor surging and design limitations.
Innovation Solution
A compact actuator device with a drive unit and coupling unit moves an adjustment mechanism between open and closed positions, directly altering the compressor inlet cross section without the need for additional transmission or gearbox units, stabilizing the compressor characteristic map.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If complex actuator systems with transmission and gearbox units are used to adjust the compressor inlet cross section, then the adjustment mechanism can be actuated, but the system becomes large and complex with increased installation space requirements
Solution Approach 1:
The patent extracts and eliminates the complex transmission and gearbox units from the actuator system, retaining only the essential drive unit and coupling unit. This extraction resolves the contradiction by removing unnecessary complexity while preserving the core adjustment functionality.
Solution Approach 2:
Instead of using a complex transmission system to multiply motion, the patent inverts the approach by using a simple coupling unit that directly translates drive unit motion into adjustment mechanism movement. This inversion eliminates the need for intermediate transmission stages.
2Ease of operation
If complex actuator systems with transmission and gearbox units are used to adjust the compressor inlet cross section, then the adjustment mechanism can be actuated, but the dimensions and installation space requirements increase
Solution Approach 1:
The patent removes the bulky transmission and gearbox units from the actuator system, keeping only the compact drive unit and coupling unit. This extraction directly reduces the volume and installation space requirements while maintaining adjustment functionality.
Solution Approach 2:
The patent merges the functions of the drive unit and coupling unit into a tightly integrated assembly, eliminating the need for separate transmission components. This merging reduces the overall volume and simplifies the spatial arrangement.
3Adaptability or versatility
If conventional actuator devices are used, then the adjustment mechanism can be moved, but the system becomes complex and design limitations arise
Solution Approach 1:
The patent extracts the complex transmission and gearbox units from conventional actuator devices, retaining only the essential drive unit and coupling unit. This extraction resolves the contradiction by removing complexity that limited design flexibility while preserving adjustment functionality.
Solution Approach 2:
The patent segments the actuator device into distinct functional modules: the drive unit and the coupling unit. This segmentation allows for independent optimization of each module and simplifies integration into different compressor designs, thereby improving adaptability.

AI summary
This invention relates to a compressor 100 for a supercharger 10. The compressor 100 comprises a compressor housing 110 with a compressor inlet 112 and a compressor outlet 114. The compressor 100 furthermore comprises an adjustment mechanism 200 and an actuator device 300. The adjustment mechanism 200 comprises an adjustment ring 210 and a plurality of shutter elements 220 for changing an inlet cross section 112a of the compressor inlet 112. The actuator device 300 comprises a drive unit 310 and a coupling unit 320. The actuator device 300 is thus coupled, via the coupling unit 320, to the adjustment mechanism 200 in order to move the adjustment mechanism 200 between a first position and a second position.
