Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If rectal temperature measurement and manual counting are used, then body temperature and physical activity can be measured, but the method is time-consuming, causes stress to animals, and exposes personnel to health risks

Engineering Contradiction:
Improvetemperature measurement accuracyVSAvoidmeasurement time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical measurement methods (rectal thermometers and hand-held counting machines) with an automated video-based system using heat image cameras and computer processing. This substitution eliminates the need for direct physical contact with animals while continuously monitoring temperature and activity parameters, thereby reducing measurement time and animal stress.

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

Solution Approach 2:

The patent uses heat image cameras to create thermal copies or representations of the animals' body temperature distribution. Instead of physical contact measurement, the system captures and processes thermal images to determine body temperature, enabling non-invasive, continuous, and rapid measurement without exposing personnel to health risks.

Inventive Principle:
Principle #26Copying

2Measurement precision

If manual rectal temperature measurement is performed, then body temperature data can be obtained, but the procedure is tedious and alters animal behavior

Engineering Contradiction:
Improvetemperature measurementVSAvoidanimal stress
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The system replaces the mechanical rectal measurement process with a non-contact optical measurement system. Heat image cameras capture thermal radiation from the animals' bodies, and computer algorithms process these images to determine body temperature, completely eliminating the stress caused by physical contact and restraint.

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

Solution Approach 2:

The patent creates a thermal copy of the animal's body through heat image camera imaging. This optical copy allows temperature measurement without physical interaction, preserving the animal's natural behavior while obtaining accurate temperature data continuously over time.

Inventive Principle:
Principle #26Copying

3Productivity

If automated heat image camera system is used, then simultaneous monitoring of multiple animals is enabled, but device complexity increases

Engineering Contradiction:
Improvesimultaneous monitoring capabilityVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements a multi-functional system where heat image cameras simultaneously perform multiple tasks: capturing thermal images for temperature measurement, tracking animal movements for activity monitoring, and providing visual records for behavioral analysis. This universal approach enables monitoring of multiple animals with a single integrated system, improving productivity despite increased complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent introduces a computer as an intermediary that processes complex image data from heat image cameras. The computer runs algorithms to automatically extract temperature and activity information from thermal images, managing the system's complexity by automating data processing and enabling simultaneous monitoring of multiple animals without requiring manual intervention for each animal.

Inventive Principle:
Principle #24Intermediary (Mediator)
