Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If magnetic domain manipulation is used in magnetic shift registers, then memory storage capability is improved, but operation stability deteriorates due to complexity of control
Solution Approach 1:
The magnetic memory device is segmented into multiple extending portions (first, second, third extending portions) with different orientations. Each portion can be independently controlled through the conductive member, allowing separate manipulation of magnetic domains in different spatial directions. This segmentation enables stable operation by breaking down the complex control into manageable directional components.
Solution Approach 2:
The invention introduces dimensional diversity by extending magnetic members in different directions (first direction, second direction, third direction) rather than using uniform linear structures. The conductive member extends in a fourth direction that is inclined relative to the magnetic extending directions, creating a multi-dimensional control architecture that enhances both storage capability and operational stability.
2Quantity of substance
If multiple extending portions are used to enhance storage capability, then memory capacity is improved, but device complexity increases
Solution Approach 1:
The conductive member serves multiple functions simultaneously: it acts as an electrical conductor for current flow, generates magnetic fields through current, and provides structural support for the overlapping portion configuration. This multi-functionality reduces the need for separate components, thereby increasing memory capacity without proportionally increasing device complexity.
Solution Approach 2:
The first, second, and third extending portions are merged into a unified magnetic member structure that shares common fabrication processes and material composition. The conductive member is merged with the magnetic members through overlapping configuration, creating an integrated structure that achieves high memory capacity while maintaining manufacturing simplicity.
