Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a thermometer is used to measure animal body temperature individually, then measurement accuracy is improved, but measurement time and operational difficulty increase significantly

Engineering Contradiction:
Improvebody temperature measurement accuracyVSAvoidmeasurement time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces the mechanical thermometer-based measurement system with a wireless implantable sensor system that automatically measures and transmits temperature data. The implant device includes a temperature sensor, microcontroller, and wireless communication module that continuously monitor body temperature and transmit data to external devices without mechanical contact, thereby maintaining measurement accuracy while eliminating time-consuming manual operations.

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

Solution Approach 2:

The implant device performs self-service by automatically measuring body temperature, storing data locally, and transmitting it wirelessly without requiring manual intervention. The device autonomously manages power consumption by entering low-power modes between measurements and only activating transmission when data needs to be sent, eliminating the need for continuous human operation while maintaining accurate temperature monitoring.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If image capturing is used to estimate animal body temperature, then operational ease is improved, but measurement accuracy deteriorates as it only measures surface temperature

Engineering Contradiction:
Improveoperational easeVSAvoidcore body temperature measurement accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent employs a nested structure where a miniature temperature sensor is implanted inside the animal's body, allowing core temperature measurement from within. The sensor is housed in a biocompatible capsule that is inserted into subcutaneous tissue or specific organs, enabling direct contact with internal body environments while remaining externally accessible for wireless data transmission, thus achieving both ease of operation and core temperature accuracy.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Duration of action of moving object

If an implant device continuously measures and stores body temperature data using battery power, then measurement continuity is improved, but battery power consumption increases

Engineering Contradiction:
Improvecontinuous measurement durationVSAvoidbattery power consumption
Core Design Contradiction:
Duration of action of moving objectVSUse of energy by moving object

Solution Approach 1:

The implant device implements periodic action by measuring temperature at predetermined intervals rather than continuously, storing measurements in local memory, and transmitting data in periodic batches when powered by the external charging device. The microcontroller manages power by entering sleep modes between measurement cycles and only activating the radio transmitter when data transmission is required, significantly reducing average power consumption while maintaining continuous monitoring capability.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The device performs preliminary action by pre-storing temperature measurements in local memory before external power is available. When the external charging device powers the implant, the pre-collected data is immediately transmitted without requiring continuous power during storage, allowing the device to accumulate measurements during low-power states and clear the buffer efficiently when power is supplied.

Inventive Principle:
Principle #10Preliminary action

4Duration of action of stationary object

If wireless power transmission is used to charge the implant device, then device life is extended, but system complexity increases

Engineering Contradiction:
Improvedevice lifeVSAvoidsystem complexity
Core Design Contradiction:
Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

The external charging device is designed with multi-functionality, serving both as a wireless power transmitter and as a data reception and processing unit. The same external device that charges the implant also receives, stores, and analyzes temperature data, eliminating the need for separate charging infrastructure and reducing overall system complexity despite the added wireless power transmission capability.

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