Solution Overview

Problem

Existing connection devices for coupling hose sections to line sections are complex and require multiple parts, increasing manufacturing effort and time, while also lacking versatility in connector designs.

Innovation Solution

A connection device with a housing part, a connecting piece, and a valve device that includes a movable valve body with sealing surfaces, allowing for various connection methods such as screwing, bayonet locking, or plugging, and featuring a check or double check valve with optimized sealing angles for efficient fluid flow control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing connection devices are used to couple hose sections to line sections, then the connection is reliable, but the device complexity increases due to multiple parts

Engineering Contradiction:
Improveconnection reliabilityVSAvoidnumber of parts
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the connecting piece and valve body into a single integrated component. The connecting piece includes both the connection functionality (for coupling hose sections to line sections) and the valve functionality (for controlling fluid flow) within one unified structure, eliminating the need for separate valve components while maintaining reliable connection and flow control

Inventive Principle:
Principle #5Merging (Combining)

2Ease of manufacture

If existing connection devices with multiple parts are used, then the connection functionality is complete, but the manufacturing effort and time increase

Engineering Contradiction:
Improvemanufacturing effortVSAvoidnumber of parts
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

By integrating the valve body directly into the connecting piece as a unified component, the patent reduces the total number of parts that need to be manufactured and assembled. This single integrated component can be produced in one manufacturing process, significantly reducing manufacturing effort and time compared to producing multiple separate components that require assembly

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If existing connection devices are used, then the connection is functional, but the adaptability to different connector designs is limited

Engineering Contradiction:
Improveconnector design versatilityVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The integrated connecting piece with built-in valve is designed to accommodate different connector types and configurations. The universal design allows it to work with various hose section and line section configurations while maintaining the same simplified structure, enabling adaptability to different connector designs without increasing device complexity

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