Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If electrical components are brought closer together to miniaturize the device, then device size is reduced, but noise interference increases
Solution Approach 1:
The device is segmented into two separate substrates: first substrate containing sensors and second substrate containing communication module. This spatial segmentation isolates noise-sensitive sensors from noisy communication components, reducing electromagnetic interference while maintaining miniaturization.
Solution Approach 2:
A dedicated communication channel is introduced as an intermediary between the sensors on the first substrate and the communication module on the second substrate. This isolated channel acts as a mediator that prevents noise coupling between the two substrates while enabling reliable data transmission.
2Volume of moving object
If device size is reduced, then miniaturization is achieved, but battery life is compromised
Solution Approach 1:
By segmenting the device into functional substrates with an isolated communication channel, power consumption is optimized through reduced electromagnetic interference and more efficient signal transmission, thereby extending battery life despite miniaturization.
Solution Approach 2:
The patent replaces traditional wired communication approaches with an isolated communication channel that uses optical or magnetic field coupling, eliminating the need for direct electrical connections and reducing power consumption associated with electrical signal transmission across substrate boundaries.
3Volume of moving object
If device size is reduced, then miniaturization is achieved, but wireless communication capabilities are compromised
Solution Approach 1:
The communication channel transitions from traditional planar electrical traces to a three-dimensional isolated channel that can utilize optical or magnetic fields, enabling robust wireless communication capabilities within the constrained miniaturized form factor.
Solution Approach 2:
The isolated communication channel serves as an intermediary that enables reliable wireless communication by providing a dedicated, noise-isolated pathway for data transmission between sensors and the communication module, maintaining communication capability despite device miniaturization.
