Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If batteries are mounted on the main system board, then power supply capability is provided, but space utilization is reduced and heat interference increases
Solution Approach 1:
The battery is integrated into the memory module structure itself, merging the power supply function with the memory storage function. This eliminates the need for separate batteries mounted on the system board, thereby improving space utilization while maintaining power supply capability.
Solution Approach 2:
The battery is positioned within the memory module assembly, nested among the memory chips and circuit board. This nesting approach allows the battery to occupy space that would otherwise be unused or dedicated to other components, optimizing the overall space utilization of the memory module.
2Power
If batteries are mounted on the main system board, then power supply capability is provided, but heat interference affects battery performance
Solution Approach 1:
The memory module is divided into distinct functional zones: a first surface for memory chips and a second surface for the battery. This segmentation physically separates the battery from heat-generating components, reducing heat interference while maintaining power supply capability.
Solution Approach 2:
An insulating layer is introduced as an intermediary between the battery and the circuit board. This insulating layer serves as a thermal barrier that reduces heat transfer to the battery, thereby minimizing heat interference and improving battery performance.
3Power
If additional batteries are added, then power supply capability is enhanced, but module volume increases
Solution Approach 1:
The memory module is designed to perform multiple functions within a single integrated structure: data storage, power supply, and thermal management. By making the module multi-functional, the design eliminates the need for additional separate batteries, thereby enhancing power supply capability without increasing module volume.
