Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional two-dimensional storage methods are used, then the storage system is simple and easy to manufacture, but the storage capacity per area is limited
Solution Approach 1:
The patent transitions from two-dimensional surface storage to three-dimensional volume storage by creating recesses with varying depths, shapes, and sizes within the substrate. This dimensional expansion allows multiple bits of information to be encoded in a single spatial location, dramatically increasing storage capacity per unit area while managing structural complexity through systematic encoding schemes.
Solution Approach 2:
The invention encodes information by varying multiple parameters of the recesses simultaneously: depth (z-dimension), shape (cross-sectional geometry), and size (dimensions). Each parameter combination represents a unique data value, enabling multi-bit storage per recess location and resolving the contradiction between storage capacity and structural complexity.
2Quantity of substance
If the size of structures is increased to improve storage capacity, then more information can be stored, but the area occupied by each structure increases reducing overall density
Solution Approach 1:
By exploiting the third dimension (depth) through variable recess depths and shapes, the patent enables increased information capacity without proportionally increasing the surface area footprint. Multiple data values are packed into the vertical space beneath each surface location, effectively decoupling storage capacity from planar area occupation.
Solution Approach 2:
The recess structures are nested within the substrate volume, with information encoded through the three-dimensional geometry of each recess. This nesting approach allows maximum utilization of the available substrate volume, packing more information into the same footprint by utilizing vertical space efficiently.
3Quantity of substance
If more storage elements are packed into the same area, then storage density increases, but the precision required for creating and detecting each element increases
Solution Approach 1:
The patent encodes multiple bits of information through variations in recess parameters (depth, shape, size) rather than relying solely on the presence or absence of discrete elements. This parameter-based encoding reduces the number of separate storage elements needed, thereby lowering the manufacturing precision requirements while maintaining high storage density.
Solution Approach 2:
By utilizing the depth dimension for information encoding, the invention reduces the lateral density of storage elements required. Fewer, more robust three-dimensional features are needed compared to two-dimensional patterns, which relaxes the precision demands on manufacturing and detection systems while achieving comparable or superior storage density.
