Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional thermal processes are used for manufacturing flexible electronic devices, then manufacturing simplicity is maintained, but manufacturing speed is slow
Solution Approach 1:
The patent replaces traditional thermal processing methods with UV irradiation curing for the flexible battery and electronic components. This substitution enables rapid curing and manufacturing without the slow thermal processes, significantly improving manufacturing speed while maintaining ease of manufacture through a simpler, faster curing mechanism.
2Reliability
If high-pulse current is used for Bluetooth communications, then communication performance is improved, but device capability requirements increase beyond current flexible electronic devices
Solution Approach 1:
The patent employs periodic pulsed current delivery through the flexible battery to meet the high-pulse current requirements for Bluetooth communication. The battery is designed to deliver high current in periodic pulses rather than continuous current, enabling reliable wireless communication while maintaining compatibility with flexible electronic device constraints.
Solution Approach 2:
The patent changes the electrical parameters of the flexible battery to accommodate high-pulse current demands. By modifying the battery's internal structure and electrochemical properties, it can deliver the necessary high-pulse currents for Bluetooth communication without requiring complex external power sources or amplification circuits.
3Use of energy by moving object
If external energy sources are used, then energy supply is maintained, but device portability and integration are reduced
Solution Approach 1:
The patent merges the energy source directly into the flexible electronic device by integrating a flexible battery with the circuit board and electronic components. This combination eliminates the need for external power sources, adapters, or wired connections, enabling complete portability and self-containment while maintaining reliable energy supply for medical monitoring and communication functions.
