Solution Overview

Problem

Existing connecting systems for fluid components, such as pneumatic and hydraulic components, face issues with increased assembly time, width, and potential leak points due to the use of tapered threaded ports and screws, and require separate systems for different thread formats, leading to inventory complexities and tool dependency.

Innovation Solution

A modular coupling system featuring a connector with a cylindrical center section, radially extending wings, and flanges, which allows for zero-space assembly and uses snap openings and alignment tabs for secure rotation and locking without adding width, utilizing a locking tab mechanism for secure attachment and sealing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If tapered threaded ports and screws are used to connect fluid components, then secure attachment and sealing are achieved, but assembly time increases and tool dependency is required

Engineering Contradiction:
Improvesecure attachment and sealingVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The connector is divided into separate functional elements: a body portion with integrated sealing features and a distinct locking mechanism with locking tabs. This segmentation allows the locking tabs to engage with slot features in a snap-fit manner without requiring threaded fasteners or additional sealing components, thereby reducing assembly time while maintaining secure attachment and sealing reliability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sealing feature is merged directly into the connector body through an integrated O-ring groove and sealing surface design. This eliminates the need for separate sealing elements and simplifies the assembly process, allowing the connector to achieve both secure attachment and sealing in a single integration step without requiring additional tools or assembly operations

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If tapered threaded ports are used on component ends, then fitting installation is enabled, but assembly width increases and inventory complexity increases

Engineering Contradiction:
Improvefitting installation capabilityVSAvoidassembly width
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The connector body is designed with a universal interface that integrates both the sealing function and the connection function in a single component. The standardized body design with integrated O-ring groove and locking tab features allows the same connector type to be used across different applications, eliminating the need for separate threaded port fittings and reducing assembly width while maintaining fitting installation capability through the locking mechanism

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

3Adaptability or versatility

If multiple separate connection systems are used for different thread formats, then various thread types are supported, but device complexity and inventory requirements increase

Engineering Contradiction:
Improvethread format compatibilityVSAvoidconnection system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single standardized connector design with integrated locking tabs and O-ring sealing features serves as a universal connection system that can replace multiple specialized connection systems for different thread formats. This universal design maintains adaptability by providing consistent sealing and locking functionality across various applications while significantly reducing device complexity and eliminating the need to stock multiple connection system variants

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

AI summary

A modular coupling system comprises a connector (200, 201) having a generally cylindrical center section (224) with a bore (208) extending from a front face (206) of the connector (200, 201) through to a back side of the connector. The connector (200, 201) has a first (220) and a second wing (222) extending from the generally cylindrical center section (224) of the connector (200, 201). A first flange (202) extends from a front side of the first wing towards a top side of the connector (200, 201), and a second flange (204) extends from a back side of the first wing towards a bottom side of the connector (200, 201). A third flange (202) extends from a front side of the second wing towards the bottom side of the connector (200, 201), and a second flange (204) extends from a back side of the first wing towards the top side of the connector (200, 201).
