Segmented Manifold Head Connectors for Serviceable Airtight Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current internal combustion engines face challenges in servicing the junctions between intake manifolds and cylinder heads due to air leaks caused by seal dry-out or wear, requiring the removal of entire components, which is time-consuming and energy-intensive.
Innovation Solution
A manifold-head connector assembly comprising proximal, middle, and distal jumper tubes with exterior engagement features and seals, allowing for piecemeal assembly and disassembly to service individual junctions without removing the entire intake manifold or cylinder head, ensuring airtight seals and adjustable connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If seals at the intake manifold and cylinder head junction are serviced by removing entire components, then seal replacement can be performed, but significant time and energy are consumed
Solution Approach 1:
The connector assembly is divided into multiple separate jumper tube segments (proximal, middle, distal) that can be independently removed and serviced. This segmentation allows the seal at the cylinder head junction to be accessed and replaced without removing the entire intake manifold or connector assembly, thereby reducing service time while maintaining seal integrity.
2Reliability
If entire intake manifolds and cylinder heads are removed for junction servicing, then seals can be replaced, but the process becomes energy-intensive
Solution Approach 1:
By segmenting the connector assembly into removable jumper tube sections, the seal replacement process only requires removing the specific segment containing the worn seal, rather than removing entire energy-intensive components like the intake manifold or cylinder head. This reduces the energy required for servicing while ensuring proper seal condition.
3Stability of the object's composition
If fixed configuration connections are used between intake manifold and cylinder head, then structural stability is achieved, but serviceability of individual junctions is reduced
Solution Approach 1:
The connector assembly employs removable and reconfigurable jumper tube segments with engagement features that allow for stable operation during engine运行, but can be easily disconnected and reconnected for servicing. This dynamic design enables individual junctions to be accessed and repaired while maintaining structural stability during normal operation.
4Adaptability or versatility
If modular components with adjustable angular connections are used, then adaptability to different engine configurations is improved, but device complexity increases
Solution Approach 1:
The connector is segmented into multiple standardized jumper tube sections with consistent engagement features. This segmentation provides adaptability to different engine configurations by allowing selective assembly and angular adjustment of segments, while the standardized design of each segment keeps individual component complexity manageable.
Solution Approach 2:
Each jumper tube segment is designed as a universal module with standardized engagement features that can be configured in various arrangements to accommodate different engine layouts and spacing requirements. This universality provides configuration flexibility without requiring each unique configuration to be a completely different complex assembly.

AI summary
Intake manifold-cylinder head connectors and methods of assembling the same are disclosed. A distal jumper tube includes a distal jumper tube conduit with an upstream end having a first exterior engagement feature and a downstream end. A proximal jumper tube includes a proximal jumper tube conduit with an upstream end and a downstream end having a second exterior engagement feature. A middle jumper tube includes a middle jumper tube conduit with an upstream end having a third exterior engagement feature, and a downstream end having a fourth engagement feature. The first exterior engagement feature is removably coupled to the fourth exterior engagement feature, and the second exterior engagement feature is removably engaged to the third exterior engagement feature. The proximal jumper tube is in fluid receiving communication with an intake manifold conduit, and the distal jumper tube is in fluid providing communication with a cylinder head aperture.
