Problem

Milk analysis apparatuses in animal farms face reliability issues due to extreme temperatures, which affect the performance of lateral flow sticks and electronic components, and are also vulnerable to dust and insects, leading to unreliable biomarker measurements.

Innovation Solution

A milk analysis apparatus with a detachable cassette system that includes a thermoelectric element, interior and exterior heat exchange elements, a fan for air circulation, and a temperature sensor to maintain a controlled temperature between 20-30 degrees, ensuring reliable biomarker measurements by adjusting the temperature and protecting the equipment from environmental conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If the milk analysis apparatus is placed in a barn environment, then it can be used for automated milk analysis, but the extreme temperatures affect the reliability of lateral flow sticks and electronic components

Engineering Contradiction:
Improveautomated milk analysisVSAvoidreliability of lateral flow sticks and electronic components
Core Design Contradiction:
Extent of automationVSReliability

Solution Approach 1:

The apparatus is divided into separate functional modules: a detachable cassette containing lateral flow sticks, a main body housing electronic components, and a temperature control system with separate heating and cooling elements. This segmentation allows each component to be optimized and protected independently against environmental conditions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A temperature control system acts as an intermediary between the external barn environment and the internal components. The system includes temperature sensors, heating elements, and cooling elements that maintain a stable internal temperature, protecting the lateral flow sticks and electronic components from extreme external temperatures.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Use of energy by moving object

If ventilation holes are drilled into the milk analysis apparatus for increasing ventilation, then air circulation is improved, but dust and insects may affect the milk analysis apparatus and lateral flow sticks

Engineering Contradiction:
Improveair circulationVSAvoiddust and insects
Core Design Contradiction:
Use of energy by moving objectVSObject-affected harmful factors

Solution Approach 1:

The apparatus uses a sealed housing design that acts as a protective barrier against dust and insects while allowing controlled air circulation through filtered vents. The housing maintains internal pressure differential to prevent ingress of contaminants while enabling thermal management.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The temperature control system maintains an optimal internal environment that is less susceptible to environmental contaminants. By controlling temperature and humidity, the system creates a stable atmosphere that reduces the impact of dust and insects on the lateral flow sticks and electronic components.

Inventive Principle:
Principle #39Inert atmosphere (Inert environment)

3Adaptability or versatility

If the temperature inside the barn varies over the year, then the apparatus adapts to seasonal changes, but the lateral flow sticks become unreliable in extreme temperatures

Engineering Contradiction:
Improveadaptation to seasonal changesVSAvoidreliability of lateral flow sticks
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The temperature control system serves as an intermediary buffer between the varying external barn temperature and the lateral flow sticks. Temperature sensors continuously monitor the internal environment, and heating/cooling elements adjust the temperature to maintain it within the optimal range for lateral flow stick operation throughout the year.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The apparatus includes self-regulating temperature control where the system automatically adjusts heating and cooling based on internal temperature sensor readings. The control unit activates heating elements when temperature drops below the optimal range and activates cooling elements when temperature exceeds the optimal range, maintaining reliable operation without external intervention.

Inventive Principle:
Principle #25Self-service
