Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If sensors are immersed into fluidic environments for measurement, then measurement capability is achieved, but sensor fouling occurs leading to erroneous measurements

Engineering Contradiction:
Improvefluid parameter measurementVSAvoidsensor measurement accuracy
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The system divides the sensing function into separate segments: a fluid sensing chamber receives fluid samples for measurement, while the sensors remain protected within the chamber. This segmentation allows measurements to be taken without direct prolonged exposure of sensors to the bulk fluid environment, reducing fouling accumulation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The fluid sensing chamber acts as an intermediary between the fluid sample and the sensors. The chamber provides a controlled interface where fluid parameters can be measured without the sensors being directly immersed in the potentially fouling fluid environment, thus protecting sensor integrity while enabling measurements.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If sensors are continuously exposed to fluidic environments, then continuous monitoring is achieved, but maintenance costs increase due to periodic cleaning requirements

Engineering Contradiction:
Improvecontinuous monitoring capabilityVSAvoidsensor maintenance and cleaning
Core Design Contradiction:
ProductivityVSEase of repair

Solution Approach 1:

The system incorporates self-cleaning capabilities where the fluid sensing chamber can be cleaned in-place without requiring removal or disassembly of the sensors. This self-service approach maintains continuous monitoring capability while reducing maintenance complexity and costs by allowing routine cleaning to be performed automatically or with minimal intervention.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The sensing function is extracted from direct fluid immersion by using a fluid sensing chamber that can be separately cleaned. This allows the chamber to be removed or cleaned independently of the sensors, preserving sensor integrity while enabling easy maintenance of the sensing system.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If manual maintenance of sensing elements is performed periodically, then sensor integrity is maintained, but operational time is lost and costs increase

Engineering Contradiction:
Improvesensor integrityVSAvoiddowntime for manual maintenance
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system enables self-cleaning of the fluid sensing chamber without requiring manual intervention or system shutdown. This self-service capability maintains sensor integrity by keeping the sensing chamber clean while eliminating operational downtime and reducing labor costs associated with manual maintenance.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system maintains continuous operational capability by allowing cleaning of the fluid sensing chamber without interrupting the monitoring process. This ensures uninterrupted useful action while maintaining sensor integrity, eliminating time loss associated with manual maintenance shutdowns.

Inventive Principle:
Principle #20Continuity of useful action
