Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the memory device is used in mobile electronic devices such as vehicles, then the memory device can be applied to mobility applications, but the mechanical reliability deteriorates due to external impacts and vibrations
Solution Approach 1:
The patent applies beforehand cushioning by providing a buffer between the memory device and the external environment. The enclosure structure with shock-absorbing materials and the vibration isolation mechanisms are designed in advance to protect the memory device from impacts and vibrations that may occur during mobile device operation, thereby maintaining mechanical reliability while enabling mobility applications
2Adaptability or versatility
If the memory device operates in high temperature environments, then the device can function in various conditions, but the dynamic thermal throttling entry time shortens causing malfunction
Solution Approach 1:
The patent implements feedback mechanisms through temperature sensors that continuously monitor the thermal environment and provide real-time data to the control system. This feedback enables the memory device to detect temperature changes and adjust its operation accordingly, preventing malfunctions in high temperature environments while maintaining the ability to operate in various conditions
Solution Approach 2:
The patent applies preliminary action by implementing preventive thermal management measures before temperature-induced malfunctions occur. The system proactively monitors temperature conditions and initiates thermal throttling or cooling protocols in advance, preventing the shortening of dynamic thermal throttling entry time and ensuring operational stability in high temperature environments
