Innovation Solution

A system comprising a bioreactor with a non-intrusive monitoring system using infrared devices and a nozzle system for precise delivery of defoaming agents, allowing for automated foam detection and targeted distribution within the bioreactor, ensuring efficient foam remediation with minimal agent usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If defoaming agents are added manually via drop method or feed tube, then foam can be remediated, but the distribution is inadequate and excessive agent may be used

Engineering Contradiction:
Improvefoam remediation effectivenessVSAvoiddefoaming agent usage
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The system enables self-service by allowing the bioreactor to automatically detect foam conditions and trigger defoaming agent delivery without external intervention. The sensor network monitors foam levels and activates the nozzle system autonomously when thresholds are exceeded, eliminating the need for manual observation and addition.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent implements local quality by positioning multiple nozzles at specific locations within the bioreactor to deliver defoaming agents precisely where foam is detected. Rather than uniform distribution, the system targets specific zones with foam problems, optimizing agent placement and reducing overall consumption.

Inventive Principle:
Principle #3Local quality

2Difficulty of detecting and measuring

If intrusive foam level detection systems are used, then foam can be detected, but the system introduces excessive defoaming agent and may harm the biological process

Engineering Contradiction:
Improvefoam level detectionVSAvoidimpact on biological process
Core Design Contradiction:
Difficulty of detecting and measuringVSObject-affected harmful factors

Solution Approach 1:

The patent replaces mechanical/intrusive detection methods with optical or electromagnetic sensors that can detect foam levels without physically contacting or intruding into the biological fluid. This substitution allows for non-invasive monitoring that doesn't disrupt the biological process or require additional chemical agents.

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

Solution Approach 2:

The system introduces an intermediary sensing layer between the foam and the biological process. The sensors detect foam conditions from a distance or through non-contact means, acting as intermediaries that provide information without directly interacting with or potentially harming the biological system.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-generated harmful factors

If defoaming agents are added to combat foaming, then foam is reduced, but quality, time, and expense increase in subsequent product development stages

Engineering Contradiction:
Improvefoam formationVSAvoidproduct development efficiency
Core Design Contradiction:
Object-generated harmful factorsVSProductivity

Solution Approach 1:

The system performs preliminary action by detecting foam conditions early and responding immediately with targeted defoaming agent delivery. By addressing foam at its inception rather than allowing it to develop, the system prevents the need for extensive corrective measures later in the process, thereby protecting productivity in subsequent stages.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback control where sensors continuously monitor foam levels and provide real-time information to the control system. This feedback loop allows for dynamic adjustment of defoaming agent delivery, ensuring that agents are added only when and where needed, thus minimizing impact on subsequent product development stages.

Inventive Principle:
Principle #23Feedback
