Solution Overview

Problem

Conventional engine manifold designs face challenges in reducing exhaust backpressure and improving packaging due to complex shapes and flow restrictions, which hinder engine efficiency and power output.

Innovation Solution

A universal engine manifold adapter that maintains a line-of-sight between the engine exhaust port and the discharge end, or utilizes a venturi effect, to reduce obstructions and backpressure, and can be configured to fit non-standard exhaust port shapes, including square, oval, and rectangular configurations, allowing for improved exhaust flow and engine performance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If conventional exhaust manifold piping is forced to adopt a complex shape to match the exhaust port and follow sharp turns, then packaging within the engine housing is achieved, but flow restrictions increase and backpressure rises

Engineering Contradiction:
Improveexhaust flowVSAvoidpiping shape complexity
Core Design Contradiction:
Volume of moving objectVSDevice complexity

Solution Approach 1:

The exhaust system is divided into separate functional components: a simple adapter component that connects to the exhaust port and a separate exhaust pipe. This segmentation allows the adapter to maintain a simple shape for optimal flow while the exhaust pipe handles the packaging requirements, resolving the contradiction between flow volume and shape complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The adapter acts as an intermediary component between the exhaust port and the exhaust pipe. It provides a simple, direct flow path that mediates between the complex engine housing constraints and the requirement for high exhaust flow volume, eliminating the need for complex piping shapes while achieving proper packaging.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If exhaust piping is made straighter and wider to reduce backpressure, then exhaust flow improves, but the system cannot fit in tight spaces within the engine housing

Engineering Contradiction:
Improveexhaust flow rateVSAvoidspace requirements
Core Design Contradiction:
ProductivityVSVolume of moving object

Solution Approach 1:

The adapter utilizes three-dimensional space optimization by positioning the exhaust pipe outlet in a different spatial dimension relative to the exhaust port. This allows the exhaust system to achieve high flow rates with a straighter effective flow path while fitting within tight engine housing spaces through strategic spatial arrangement rather than simply increasing pipe dimensions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If a universal adapter design is used to fit non-standard exhaust port shapes, then adaptability improves, but manufacturing precision requirements increase

Engineering Contradiction:
Improveexhaust port shape compatibilityVSAvoidadapter geometry tolerance
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The adapter is designed as a universal component that can accommodate various exhaust port shapes (square, oval, rectangular) through a single standardized design. This universality is achieved by making the adapter the adaptable element rather than customizing each exhaust port, thereby improving adaptability while maintaining consistent, achievable manufacturing tolerances for the adapter itself.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

An engine manifold adapter fluidly interconnects a fluid port of an internal combustion engine to a cylindrical conduit. The adapter comprises a stem portion extending for a flange portion. The stem portion has a pair of oppositely disposed openings formed therein. One of the openings is configured to conform to the fluid port and the other of the openings is configured to accommodate press fitting of the cylindrical conduit onto the other of the openings. A line of sight is formed between the openings. In one embodiment, the fluid port is an exhaust port and the cylindrical conduit is an exhaust pipe.
