Solution Overview

Problem

Existing media-carrying component connections, such as screw connections, face issues with guaranteed tightness, hygiene concerns due to hemp usage, and difficulty in tight spaces, while plug-in connections are not easily reversible without destruction.

Innovation Solution

A connection device featuring a sealing section with a cylindrical outer jacket and an elastic snap ring that secures the second media-carrying component to the first media-carrying component through a plug-in process, allowing for easy and non-destructive release by loosening a screw connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If screw connections with hemp are used, then sealing is achieved, but hygiene concerns arise and manual disassembly is difficult in tight spaces

Engineering Contradiction:
Improvesealing qualityVSAvoidhygiene concerns
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention extracts and removes the hemp sealing material from the connection system, replacing it with a hemp-free sealing mechanism using an elastic element and snap ring that achieve sealing without organic materials, thereby eliminating hygiene concerns while maintaining sealing quality

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention replaces the traditional mechanical screw tightening system with a snap-in mechanism using an elastic element that provides sealing through elastic deformation rather than mechanical compression of hemp, eliminating the need for manual manipulation in tight spaces

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If plug-in connections are used, then ease of assembly is improved, but non-destructive removal becomes difficult

Engineering Contradiction:
Improveassembly easeVSAvoidremoval ease
Core Design Contradiction:
Ease of operationVSEase of repair

Solution Approach 1:

The invention introduces a dynamic locking mechanism using an elastic element and snap ring that can transition between locked and unlocked states. The elastic element allows the connection to be firmly secured during operation but can be easily released by compressing the elastic element to disengage the snap ring, enabling both easy assembly and non-destructive removal

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The invention incorporates a preliminary release mechanism where the elastic element is pre-configured to allow controlled disengagement. By applying a specific releasing action (compressing the elastic element), the connection can be non-destructively removed without requiring forceful extraction or damage to components

Inventive Principle:
Principle #10Preliminary action

3Strength

If traditional screw connections are used, then connection strength is achieved, but replacement effort is high

Engineering Contradiction:
Improveconnection strengthVSAvoidreplacement time
Core Design Contradiction:
StrengthVSLoss of time

Solution Approach 1:

The invention segments the connection system into modular components: a locking piece with internal thread, an elastic element, and a snap ring. This segmentation allows the connection to be quickly assembled by snapping components together and easily replaced by reversing the process, reducing replacement time while maintaining connection strength through the combined action of the threaded locking piece and elastic securing mechanism

Inventive Principle:
Principle #1Segmentation
