Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing fluid-technical devices struggle to efficiently subdivide fluid channels into multiple, independently pressurizable sections, as existing solutions require simultaneous tool access from both sides for assembly and disassembly, limiting the ability to install multiple dividing pieces in a single fluid channel.

Innovation Solution

A dividing piece with a clamping device integrated into a clamping extension that protrudes axially from the dividing section, featuring transversely deformable sealing rings and a clamping mechanism that allows for secure sealing and rotation prevention, enabling easy insertion and actuation from a single axial side, allowing multiple subdivision pieces to be installed in succession.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a dividing piece with a clamping device requiring simultaneous tool access from both sides is used, then reliable clamping and sealing is achieved, but the ability to install multiple dividing pieces in a single fluid channel is limited

Engineering Contradiction:

Improveclamping and sealing reliabilityVSAvoidability to install multiple dividing pieces

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The clamping device is inverted from requiring bilateral tool access to being actuable from a single axial side. The clamping extension protrudes axially from the dividing section, allowing the clamping mechanism to be operated from one side only, while still achieving reliable clamping through the radial deformation of clamping arms against the channel wall.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The clamping device is designed with a clamping extension that protrudes axially from the dividing section, changing the dimension of tool access from requiring bilateral axial access to unidirectional axial access. This dimensional change allows multiple dividing pieces to be installed in succession from the same side of the fluid channel.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Reliability

If a dividing piece with bilateral tool access is used, then secure sealing and clamping is achieved, but assembly and disassembly time increases

Engineering Contradiction:

Improvesealing and clamping securityVSAvoidassembly and disassembly time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The clamping device is inverted from requiring bilateral tool access to being actuable from a single axial side. The clamping extension protrudes axially from the dividing section, allowing the clamping mechanism to be operated from one side only, reducing assembly and disassembly time while maintaining reliable clamping.

Inventive Principle:

Principle #13The other way round (Inversion)

3Ease of manufacture

If the dividing section has a circular cross-section, then it can be easily manufactured, but it cannot be secured against rotation in the fluid channel

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidrotation resistance

Core Design Contradiction:

Ease of manufactureVSStability of the object's composition

Solution Approach 1:

The dividing section is designed with an elongated cross-section instead of a circular one, creating an asymmetric shape that provides orientation stability in the fluid channel. This asymmetric cross-section prevents rotation while still allowing for relatively simple manufacturing processes.

Inventive Principle:

Principle #4Asymmetry

AI summary

The partition piece (12) is inserted and sealed into two axially successive channel portions divided from duct section (3). A clamping device (32) is provided in partition piece, for fixing partition piece in the fluid channel (2) with respect to channel wall in fluid channel. A dividing portion (22) perpendicular to longitudinal axis of partition piece has elongated cross section corresponding to the cross-sectional shape of the fluid channel, so that it is held against rotation by the passage wall of the fluid channel. An independent claim is included for fluidic apparatus.
