Solution Overview

Problem

Current hydrostatic acceptance testing methods require time-consuming and attention-intensive preparation to avoid leaks, which can distort test results due to the need for screwing sealing joints between the tank and the test fluid feed line.

Innovation Solution

A support and connection structure featuring a sealing joint with a frustoconically-shaped centering portion and a toggle lever linkage, allowing for easy assembly and secure fluid connection between the tank and feed line, eliminating the need for screwing the sealing joint to the feed line.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If sealing joints are screwed to both the tank and the feed line, then the connection is secure and leak-free, but the preparation process becomes time-consuming and requires particular attention

Engineering Contradiction:
Improveconnection reliabilityVSAvoidpreparation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The sealing joint is divided into separate components: a base engagement element that attaches to the tank and a connecting nipple that attaches to the feed line. This segmentation allows each part to be independently prepared and assembled, reducing the overall preparation time while maintaining connection reliability through the modular design with integrated sealing elements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base engagement element is pre-assembled with the tank before the actual testing process. This preliminary action includes pre-attaching the sealing components to the tank, so that during the test setup, only the final connection to the feed line is needed, significantly reducing the time and attention required during the critical test preparation phase.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If sealing joints are screwed to both the tank and the feed line, then the connection is secure and leak-free, but the operation becomes complex and error-prone

Engineering Contradiction:
Improveconnection reliabilityVSAvoidassembly ease
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

By segmenting the sealing joint into a base engagement element and a connecting nipple, the assembly process is simplified. The base engagement element with its integrated sealing components attaches to the tank in one operation, and the connecting nipple attaches to the feed line separately, reducing the complexity and potential for errors compared to screwing a single complex joint to both components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The base engagement element acts as an intermediary component between the tank and the feed line. It provides a standardized interface that simplifies the connection process, making the operation easier and less error-prone by mediating the connection between the two main components with pre-integrated sealing mechanisms.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Extent of automation

If a frustoconically-shaped centering portion is used in the sealing joint, then the assembly is simplified and automation is enabled, but the device complexity increases

Engineering Contradiction:
Improveautomation capabilityVSAvoidsealing joint complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The frustoconical centering portion uses asymmetric geometry to provide self-alignment and guidance during assembly. This asymmetric shape enables automated assembly by providing unique orientation cues that guide the connecting nipple into the correct position relative to the base engagement element, facilitating automation while the standardized conical form keeps the added complexity manageable.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The frustoconical shape provides a curved, tapered surface that guides assembly through natural alignment. This curvature enables automated positioning by allowing the components to self-center during insertion, facilitating automation while the simple geometric form minimizes the increase in device complexity.

Inventive Principle:
Principle #14Spheroidality (Curvature)
