Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If temperature sensing and wireless communication components are integrated into healthcare garments, then monitoring capability is improved, but device complexity increases

Engineering Contradiction:
Improvetemperature monitoring capabilityVSAvoidgarment system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines the temperature sensor, wireless communication module, and power management components into an integrated monitoring unit that is embedded within the healthcare garment. This merging of multiple functions into a single integrated system improves measurement capability while managing the complexity through unified design rather than separate components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The monitoring system is designed to perform multiple functions: temperature sensing, wireless data transmission, and usage cycle tracking. This multi-functionality allows a single integrated system to address various monitoring needs (hygiene compliance, patient safety, garment maintenance) without requiring separate specialized devices for each function.

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

2Reliability

If continuous temperature monitoring is implemented, then hygiene compliance is improved, but energy consumption increases

Engineering Contradiction:
Improvehygiene compliance monitoringVSAvoidsensor battery consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system implements periodic temperature monitoring and wireless data transmission at predetermined time intervals rather than continuous monitoring. This approach maintains adequate hygiene compliance tracking while significantly reducing power consumption compared to continuous operation, allowing the battery to last through the required monitoring period.

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The system uses feedback mechanisms where temperature data is collected and analyzed to determine when transmission to the base station is necessary. The monitoring adjusts its activity based on detected temperature changes or elapsed time since last transmission, reducing unnecessary energy consumption while maintaining monitoring reliability.

Inventive Principle:
Principle #23Feedback

3Object-affected harmful factors

If detailed usage cycle information is collected and transmitted, then infection risk identification is improved, but data transmission frequency increases

Engineering Contradiction:
Improveinfection risk detectionVSAvoidwireless communication energy
Core Design Contradiction:
Object-affected harmful factorsVSLoss of energy

Solution Approach 1:

The system performs preliminary local processing of temperature data to identify significant patterns or threshold violations before triggering wireless transmission. By pre-processing data locally and only transmitting when necessary (e.g., when infection risk thresholds are exceeded or at scheduled intervals), the system improves infection detection capability while minimizing energy-consuming transmission events.

Inventive Principle:
Principle #10Preliminary action
