Solution Overview

Problem

Traditional biological particle analyzers, such as Flow Cytometers, face significant power consumption issues due to constant operation of the light emission source, leading to wasted energy and reduced battery life in portable devices, which increases size, cost, and affects reliability.

Innovation Solution

Implementing a control module that calculates and adjusts the turn-on time of the light emission source based on particle characteristics and average velocity, ensuring it is only active during testing, using detection circuits to determine when to turn the light source on and off, thereby reducing unnecessary power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the light emission source is kept on continuously, then the biological particle analyzer can perform analysis functions, but power consumption increases and battery life decreases

Engineering Contradiction:
Improveanalysis function availabilityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The light emission source is operated periodically rather than continuously. The control module turns on the light source only during the brief periods when particles are detected in the detection area, and turns it off during idle periods. This periodic operation maintains analysis functionality while dramatically reducing overall power consumption and extending battery life.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system uses detection circuits to monitor the presence of particles in real-time and provides feedback to the control module. When particles are detected, the control module activates the light emission source; when no particles are present, it deactivates the source. This feedback mechanism ensures the light source operates only when necessary for analysis, optimizing both functionality and power efficiency.

Inventive Principle:
Principle #23Feedback

2Measurement precision

If the light emission source is kept on continuously, then particle detection can be performed, but heat generation increases affecting battery life and reliability

Engineering Contradiction:
Improveparticle detection capabilityVSAvoidheat generation
Core Design Contradiction:
Measurement precisionVSTemperature

Solution Approach 1:

The light emission source is activated in short periodic bursts only when particles are detected, rather than continuous operation. This reduces cumulative heat generation while maintaining sufficient illumination for accurate particle detection during active measurement periods.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system converts the potential harm of continuous heat generation into a benefit by using intelligent control to activate the light source only when needed. The heat that would otherwise be wasted during idle periods is eliminated, extending battery life and improving reliability while maintaining detection precision.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Duration of action of moving object

If a high capacity battery is used to support continuous operation, then the portable Flow Cytometer can function longer, but device size and production cost increase

Engineering Contradiction:
Improveoperating durationVSAvoiddevice size
Core Design Contradiction:
Duration of action of moving objectVSVolume of moving object

Solution Approach 1:

By operating the light emission source periodically rather than continuously, the overall power consumption is reduced by a significant margin. This allows the use of a smaller, lighter battery while achieving the same or longer effective operating duration, as the battery only needs to supply power during active detection periods.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system changes the operational parameters of the light emission source from continuous to intermittent operation. This parameter change reduces the total energy requirement, allowing downsizing of the battery and overall device while maintaining or extending practical operating duration for portable applications.

Inventive Principle:
Principle #35Parameter changes
