Solution Overview

Problem

The existing liquid processing apparatuses suffer from pressure leakage and permanent deformation due to lateral pressure or tensile action, which compromises the sealing effect between the O-shaped seal ring and the housing, leading to reduced performance over time.

Innovation Solution

The design includes a housing with enhanced strength near the sealing portion, featuring a circular disk-shaped sealing portion and an elastic seal ring, along with threaded connections and flange portions to maintain the sealing effect, and a connector with a protrusion portion that accommodates the seal ring, ensuring a reliable sealing mechanism.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a conventional housing structure is used, then the device is simple to manufacture, but the housing deforms under lateral pressure or tensile action, compromising the sealing effect

Engineering Contradiction:
Improvehousing strengthVSAvoidhousing structure complexity
Core Design Contradiction:
StrengthVSDevice complexity

Solution Approach 1:

The housing structure implements local quality enhancement by adding a flange portion specifically at the sealing portion location. This flange portion increases the local strength and rigidity where the sealing ring is installed, preventing deformation under lateral pressure or tensile action. The rest of the housing maintains its original simple structure, so the overall device complexity increases only minimally while achieving the required strength at the critical sealing location.

Inventive Principle:
Principle #3Local quality

2Reliability

If an O-shaped seal ring is used without structural reinforcement, then the sealing structure is simple, but pressure leakage occurs due to housing deformation

Engineering Contradiction:
Improvesealing reliabilityVSAvoidsealing structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The flange portion is designed as a preliminary structural reinforcement that prevents housing deformation before it can occur during operation. By providing this rigid support structure at the sealing location in advance, the housing maintains its dimensional stability and prevents the sealing ring from being compromised by lateral pressure or tensile forces, thereby ensuring sealing reliability from the start of operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The flange portion acts as a protective cushioning structure that absorbs and distributes lateral pressures and tensile forces before they can reach the sealing ring. This preliminary protective structure prevents the transmission of harmful forces to the O-shaped seal ring, maintaining the integrity of the sealing interface and preventing pressure leakage.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Force

If the housing is subjected to lateral pressure or tensile action, then the device can withstand operational loads, but permanent deformation occurs, reducing performance over time

Engineering Contradiction:
Improveload bearing capacityVSAvoidhousing dimensional stability
Core Design Contradiction:
ForceVSStability of the object's composition

Solution Approach 1:

The flange portion provides localized reinforcement at the sealing portion, creating a rigid support structure that resists lateral pressure and tensile forces. This local quality enhancement prevents permanent deformation in the critical sealing area while allowing the rest of the housing to maintain its original design for load-bearing functions.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The housing structure effectively becomes a composite structure combining the main housing body material with the flange portion material. This composite construction provides enhanced rigidity and dimensional stability at the sealing location, allowing the housing to withstand operational loads without permanent deformation while maintaining the overall load-bearing capacity.

Inventive Principle:
Principle #40Composite materials
