Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for obtaining physiological samples, such as blood samples, are time-consuming and burdensome for subjects, requiring travel to diagnostic laboratories.
Innovation Solution
A dermal patch system with a cartridge and lancet that includes a biometric sensor and power supply, where the lancet engagement activates the sensor and power system to collect and store samples, ensuring efficient and reliable sample extraction and data capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard syringe and laboratory setting are used to obtain physiological samples, then sample collection can be performed with basic equipment, but the process becomes time-consuming and burdensome for subjects requiring travel to diagnostic laboratories
Solution Approach 1:
The dermal patch system enables subjects to perform their own sample collection at home or in medical facilities without requiring travel to a laboratory. The integrated cartridge with lancet, biometric sensor, and power supply allows the subject to independently complete the entire sampling process, eliminating the need for professional laboratory intervention and saving significant time.
Solution Approach 2:
The patent combines multiple functions into a single integrated cartridge: the lancet for sample extraction, the biometric sensor for subject identification, the power supply for operating electronic components, and the sample storage chamber. This consolidation transforms a complex laboratory-based process into a simple, self-contained device that can be used anywhere, dramatically improving ease of operation and reducing time loss.
2Productivity
If a dermal patch system with biometric sensor and power supply is implemented, then convenient and efficient sample collection is enabled, but the device complexity increases
Solution Approach 1:
The cartridge is designed as a universal platform that performs multiple functions: mechanical sample extraction via lancet deployment, biometric authentication via fingerprint sensor, power management via integrated battery, and sample storage. By making the cartridge multi-functional, the system achieves high productivity without requiring multiple separate devices, thereby limiting the increase in complexity.
Solution Approach 2:
The lancet deployment mechanism is designed to be automatically triggered when the cartridge is properly attached to the skin, eliminating the need for manual activation or complex control interfaces. The biometric sensor automatically verifies subject identity, and the power supply automatically activates components as needed. This self-service approach maintains simplicity while achieving efficient, automated operation.
