Solution Overview

Problem

Existing methods for inspecting fluid quality in systems, such as bleeding off fluid or using filters, are inadequate as they require high impurity concentrations for detection, pose safety risks, and need technical expertise, failing to provide a comprehensive indication of fluid quality across a range of impurity concentrations.

Innovation Solution

A fluid inspection apparatus with an impurity indicator, such as a magnet, integrated into the system to detect impurities within the fluid flow path, allowing for visual inspection without direct fluid interaction, using a transparent body element and light source for enhanced visibility, and a flow diagnostic apparatus to capture and analyze fluid data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Difficulty of detecting and measuring

If visual inspection methods (bleeding off fluid or using filters) are used to detect impurities, then the inspection method is simple, but it requires high impurity concentrations for detection and poses safety risks

Engineering Contradiction:
Improveimpurity detection capabilityVSAvoidsafety risks
Core Design Contradiction:
Difficulty of detecting and measuringVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an impurity indicator (such as a magnet or visual indicator) as an intermediary element that interacts with impurities in the fluid. This indicator provides a visible signal of impurity presence without requiring the user to directly handle or bleed off the fluid, thereby enabling detection while eliminating safety risks associated with direct fluid exposure

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical approach of bleeding off fluid for inspection with a field-based detection method using magnetic indicators or optical indicators. The magnetic field or optical field interacts with impurities to provide visual feedback, substituting the need for physical fluid handling and enabling detection at low impurity concentrations without safety risks

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

2Loss of substance

If filters are used to remove impurities, then material removal is achieved, but only indicates removed material not what remains in the fluid

Engineering Contradiction:
Improveimpurity removalVSAvoidfluid quality information
Core Design Contradiction:
Loss of substanceVSLoss of information

Solution Approach 1:

The patent implements a feedback mechanism where the impurity indicator continuously provides visual information about the current state of fluid quality. Unlike filters that only show what has been removed, the indicator gives real-time feedback on what remains in the fluid, enabling users to assess whether the fluid has reached acceptable quality levels

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The impurity indicator serves as an intermediary that provides information about impurities remaining in the fluid. This indicator translates the presence of impurities into visible signals, giving users direct information about current fluid quality without needing to interpret filter contents or perform complex analysis

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If visual inspection methods are used, then the method is simple, but requires technical expertise and confidence that users may not have

Engineering Contradiction:
Improveinspection simplicityVSAvoidtechnical expertise requirement
Core Design Contradiction:
Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

The patent employs color-changing indicators that automatically change appearance when impurities are present. This eliminates the need for users to interpret complex visual cues or have expertise in fluid analysis - they simply need to observe whether the indicator has changed color, making the inspection process accessible to users without technical expertise

Inventive Principle:
Principle #32Color changes

Solution Approach 2:

The patent uses parameters such as magnetic field strength or optical properties that change in response to impurity concentration. These parameter changes are translated into visible signals that are intuitive to interpret, eliminating the need for users to understand complex technical parameters or have expertise in fluid mechanics

Inventive Principle:
Principle #35Parameter changes

AI summary

A fluid inspection apparatus (100) configured to define an inspection section (102) of a fluid flow passage (12) of a system (10). The fluid inspection apparatus (100) comprises a body element (110) having a wall (112) which defines the inspection section (102), a flow inlet (114) to the inspection section (102) and a flow outlet (116) from the inspection section (102). The inspection section (102) defines a flow path (120) between the flow inlet (114) and the flow outlet (116). The body element (110) has a first side (134) and a second side (136), wherein a cavity (140) is defined in the first side (134), extending at least part of the distance between the flow inlet (114) and the flow outlet (116), the cavity (140) being offset from and fluidly isolated from the flow path (120). An impurity indicator (200) is located in the cavity (140) such that it is fluidly isolated from the flow path (120), the impurity indicator (200) being a magnet (202) configured to indicate the presence of an impurity in fluid flowing through the flow path (120). The second side (136) of the body element (110) defines a viewing region (138) to inspect the surface of the inspection section (102) adjacent to the impurity indicator (200).
