Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate applicator and sensor module are used, then the system is flexible and reusable, but the user operation becomes complex and time-consuming
Solution Approach 1:
The patent combines the applicator and sensor module into a single integrated assembly where the sensor module is preinstalled within the applicator. This integration eliminates the need for separate handling of multiple components, simplifying the attachment process while maintaining the functional benefits of both components
Solution Approach 2:
The sensor module is preinstalled in the applicator during manufacturing, so that when the user operates the applicator, the sensor module is already positioned and ready for immediate attachment to the skin. This preliminary preparation eliminates complex user assembly steps
2Reliability
If a disposable transmitter is used with each sensor module, then each component can be optimized for single-use safety, but the cost increases and waste is generated
Solution Approach 1:
The system is segmented into disposable components (sensor module and applicator) and a reusable component (transmitter). The transmitter is separated from the single-use sensor module, allowing the transmitter to be used multiple times while the sensor module and applicator are discarded after one use, reducing waste and cost
3Productivity
If the user manually attaches the sensor module separately, then the applicator can be reused, but additional user tasks increase the complexity and time required
Solution Approach 1:
The applicator and sensor module are merged into a single operational unit. When the user operates the applicator to attach the sensor to the skin, both components work together as one integrated system, eliminating the need for separate manual attachment steps and reducing user task complexity
4Measurement precision
If the sensor module and applicator are disposable, then accuracy and safety are ensured, but the initial cost per use increases
Solution Approach 1:
The system is divided into disposable parts (sensor module and applicator) that ensure accuracy and safety through single-use design, and a reusable transmitter that reduces overall waste. This segmentation allows the critical measurement components to be disposable while the expensive electronics are reused

AI summary
The present invention relates to a sensor applicator assembly for a continuous glucose monitoring system and provides a sensor applicator assembly for a continuous glucose monitoring system, which is manufactured with a sensor module assembled inside an applicator, thereby minimizing additional work by a user for attaching the sensor module to the body and allowing the sensor module to be attached to the body simply by operating the applicator, and thus can be used more conveniently. A battery is built in the sensor module and a separate transmitter is connected to the sensor module so as to receive power supply from the sensor module and be continuously used semi-permanently, thereby making the assembly economical. The sensor module and the applicator are used as disposables, thereby allowing accurate and safe use and convenient maintenance.
