Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compressor inlet adjustment mechanisms are cumbersome, requiring multiple parts, increasing weight, manufacturing costs, and maintenance needs due to complex actuation systems and intermediate components.
Innovation Solution
A compressor inlet adjustment mechanism utilizing rotatable orifice elements and a transmission ring, where an elongated bearing pin transmits actuation force directly to other orifice elements, eliminating the need for intermediate parts and reducing wear through optimized bearing pin and coupling element placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional adjustment mechanisms with multiple intermediate elements are used, then the compressor inlet cross-section can be adjusted, but the device complexity, weight, and manufacturing costs increase
Solution Approach 1:
The patent combines multiple intermediate elements (lever assembly, transmission elements) into a single integrated transmission ring structure. The transmission ring directly couples all orifice elements to the actuator, eliminating the need for separate lever assemblies and intermediate transmission components. This merging reduces the number of parts while maintaining the adjustment functionality.
Solution Approach 2:
The transmission ring serves multiple functions simultaneously: it acts as a transmission element, a structural support, and a direct coupling mechanism between the actuator and all orifice elements. This multi-functional design replaces multiple specialized components with a single universal element, reducing complexity.
2Adaptability or versatility
If traditional adjustment mechanisms with lever assemblies are used, then the compressor inlet cross-section can be adjusted, but the weight increases
Solution Approach 1:
The patent merges the lever assembly and transmission elements into a single transmission ring structure. By combining these separate components into one integrated element, the total mass of the adjustment mechanism is reduced while maintaining the ability to adjust the compressor inlet cross-section.
3Adaptability or versatility
If traditional adjustment mechanisms with multiple intermediate elements are used, then the compressor inlet cross-section can be adjusted, but the manufacturing costs increase
Solution Approach 1:
The patent combines multiple separately manufactured components (lever assembly, transmission elements, coupling mechanisms) into a single transmission ring that can be manufactured as one piece. This reduces the number of manufacturing steps, assembly operations, and quality control checks required, thereby lowering manufacturing costs.
Solution Approach 2:
The patent extracts and eliminates unnecessary intermediate elements from the traditional adjustment mechanism. By removing redundant components that do not add functional value, the design simplifies the manufacturing process and reduces material costs.
4Adaptability or versatility
If traditional adjustment mechanisms with multiple intermediate elements are used, then the compressor inlet cross-section can be adjusted, but the maintenance needs increase due to wear
Solution Approach 1:
The patent merges multiple separate transmission elements into a single integrated transmission ring. This eliminates the multiple contact interfaces and potential wear points that would exist between separate components. The reduced number of moving parts and contact surfaces directly lowers maintenance needs and improves reliability.
5Adaptability or versatility
If more intermediate components are used in the adjustment mechanism, then the compressor inlet cross-section can be adjusted, but the space requirements increase
Solution Approach 1:
The patent combines multiple intermediate components into a single transmission ring structure that occupies significantly less space than the distributed arrangement of separate levers and transmission elements. This integration allows the adjustment mechanism to fit within a more compact volume while maintaining full adjustment functionality.

AI summary
The present invention relates to an adjustment mechanism (10) for variably adjusting the cross-section of a compressor inlet (312) . The adjustment mechanism comprises a plurality of rotatable orifice elements (100,100') and a transmission ring (210) . Each orifice element has a plate body (130) , a coupling element (110) and a bearing pin (120,120') . The transmission ring is mechanically coupled to the plurality of orifice elements via the coupling elements. One of the orifice elements is configured as a drive orifice element. The bearing pin of the drive orifice element is configured as an elongated bearing pin (120') . The elongated bearing pin is configured longer than the bearing pins of the other orifice elements. Furthermore, the elongated bearing pin is adapted to be coupled to an actuation system (230) such that when the drive orifice element is moved by the actuation system, movement is transmitted from the drive orifice element via the transmission ring to the other orifice elements.
