Solution Overview
Problem
Existing sampling apparatuses for viscous aqueous solutions of cellulose pulp fiber in pressurized systems face issues with clogging and inhomogeneous sampling due to complex flow paths and restricted flow, leading to waste and spillage during sample collection.
Innovation Solution
A sampling apparatus with a unitary body coupling and shut-off valve design featuring overlapping orifices to create straight flow paths, minimizing bends and using a low-flow-restriction shut-off valve to prevent clogging and ensure controlled discharge into a sample container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex flow paths with bends and flow restriction are used in sampling apparatus, then flow control is achieved, but clogging occurs and sampling homogeneity deteriorates
Solution Approach 1:
The flow path is segmented into multiple parallel straight paths through multiple orifices rather than a single complex path, allowing flow distribution while maintaining straight-line flow in each segment to prevent clogging
Solution Approach 2:
The invention transitions from a single complex three-dimensional flow path with bends to multiple parallel two-dimensional straight flow paths through overlapping orifices, eliminating flow restriction and clogging while maintaining flow control
2Reliability
If complex flow paths with bends are used in sampling apparatus, then flow control is achieved, but sampling homogeneity deteriorates
Solution Approach 1:
The flow path is segmented into multiple parallel straight paths through multiple orifices rather than a single complex path, allowing flow distribution while maintaining straight-line flow in each segment to prevent clogging
Solution Approach 2:
The invention transitions from a single complex three-dimensional flow path with bends to multiple parallel two-dimensional straight flow paths through overlapping orifices, eliminating flow restriction and clogging while maintaining flow control
3Object-generated harmful factors
If minimal flow restriction is used to prevent clogging, then clogging is reduced, but controlled discharge becomes difficult
Solution Approach 1:
The shut-off valve provides dynamic control capability that can be activated when needed, allowing the system to transition between open (minimal restriction) and closed (controlled discharge) states, resolving the contradiction between preventing clogging and enabling controlled discharge
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus effectively reduces clogging and ensures homogeneous sampling by maintaining minimal flow restriction and controlled discharge, preventing waste and spillage during the filling of sample bottles.
Implementation Method 1
The first orifice is disposed in flow-through communication with the third orifice from the first side to the second side, and the third orifice is disposed in flow-through communication with the second orifice from the second side to the first side. A first flow path through the first orifice is disposed parallel with a second flow path through the third orifice

AI summary
A combination includes a container and a coupling configured to receive the container. The coupling has a unitary body having a first side and an opposing second side, the first side comprising a first orifice and a second orifice, the second side comprising a third orifice. The first orifice is disposed in flow-through communication with the third orifice from the first side to the second side, and the third orifice is disposed in flow-through communication with the second orifice from the second side to the first side. A first flow path through the first orifice is disposed parallel with a second flow path through the third orifice, and a third flow path through the third orifice is disposed parallel with a fourth flow path through the second orifice.
