Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional ultrasonic coupling devices are used, then ultrasound transmission is achieved, but wireless communication and hydration sensing capabilities are lacking
Solution Approach 1:
The patent combines ultrasonic transmission, wireless communication (NFC), and hydration sensing into a single integrated coupling device. The hydrogel layer serves multiple functions: it transmits ultrasound waves, contains NFC antennas for wireless communication, and includes hydrophilic particles that enable hydration level detection, eliminating the need for separate devices for each function.
Solution Approach 2:
The coupling device is designed as a multi-functional system where the hydrogel layer simultaneously performs ultrasonic coupling, wireless communication enablement, and hydration sensing. This universal design allows a single device to replace multiple separate instruments, enhancing versatility without proportionally increasing complexity.
2Reliability
If hydrogel with nanoparticles is used, then ultrasound transmission and hydration sensing are improved, but manufacturing complexity increases
Solution Approach 1:
The patent specifies particular parameters for the hydrogel including water content of at least 10 wt%, particle size less than 100 nm, and specific hydrophilic particle compositions. These parameter specifications optimize ultrasound transmission and hydration sensing performance while providing clear manufacturing guidelines that balance reliability with manufacturability.
3Adaptability or versatility
If foam with aperture structure is used, then NFC device integration is enabled, but structural complexity increases
Solution Approach 1:
The patent employs a foam material with an aperture structure that provides a cavity for integrating the NFC device. The porous foam structure allows the hydrogel to be applied while accommodating the wireless communication components, enabling NFC functionality without requiring a completely different structural design.
