Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing supercharger connection to the hydraulic cooling circuit is complex, costly, and inefficient, leading to increased manufacturing costs, bulkiness, and reduced heat dissipation, which affects the reliability and positioning of the supercharger in vehicles.
Innovation Solution
A supercharger design where the hydraulic connector is directly integrated into the head, allowing for a single-piece connection that simplifies assembly, reduces bulk, and enhances liquid flow rate, thereby improving connection efficiency and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ports are screwed to the head of the supercharger to connect the cooling circuit, then the connection is established, but the assembling complexity increases and manufacturing costs rise
Solution Approach 1:
The patent integrates the connection ports directly into the head structure as integral features rather than separate components. The head includes first and second connection ports formed directly in its body, eliminating the need for separate port components that need to be screwed in and connected to hydraulic connectors. This merging of functions reduces the number of parts and assembly steps while maintaining reliable hydraulic connections for the cooling circuit.
2Strength
If ports are screwed to the head with threaded connections, then the connection is secure, but the manufacturing costs increase due to critical threading requirements
Solution Approach 1:
The connection ports are formed as integral features of the head during the head manufacturing process (casting or machining), rather than being separate threaded components. This eliminates the need for separate threading operations and reduces manufacturing complexity while maintaining secure hydraulic connections through direct integration into the head structure.
3Reliability
If hydraulic connectors are screwed to the head, then the cooling circuit is connected, but the bulk increases and positioning constraints arise
Solution Approach 1:
The connection ports are integrated directly into the head structure, eliminating the need for external hydraulic connectors that would increase bulk. The ports are formed as recesses or openings in the head itself, allowing direct connection to the cooling circuit without protruding connector components, thereby reducing the overall volume and positioning constraints of the supercharger assembly.
4Reliability
If connectors are screwed to the head, then the connection is established, but the flow rate in the cooling circuit is limited
Solution Approach 1:
The integrated connection ports provide larger, unobstructed flow passages compared to threaded connector interfaces. By forming the ports directly in the head structure, the design eliminates flow restrictions that would be introduced by threaded connections and small connector openings, thereby enabling higher flow rates in the cooling circuit and improved heat dissipation capability.
