Core Design Contradiction:
Volume of stationary objectVSManufacturing precision

Solution Approach 1:

The patent employs three-dimensional vertical interconnect components that stack electronic components in the vertical dimension rather than spreading them out in the planar dimension. This dimensional transition dramatically reduces package footprint while wafer-level processing ensures high manufacturing precision for the vertical connection paths.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent implements stacked arrangements of electronic components where multiple devices are vertically nested within a compact package structure. The vertical interconnect components penetrate through multiple stacked layers, enabling dense integration and small package size while maintaining precise electrical connections between nested components.

Inventive Principle:
Principle #7Nested doll (Nesting)

Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent creates vertical interconnect components that serve multiple functions simultaneously: providing electrical connections, enabling thermal management pathways, and facilitating mechanical stacking alignment. This multi-functionality achieves versatile three-dimensional connectivity while streamlining manufacturing processes and improving production efficiency through single-step wafer-level operations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the formation of vertical interconnect components, signal distribution structures, and component alignment features into integrated wafer-level processing operations. This merging of multiple manufacturing steps into unified processes reduces production complexity, lowers costs, and improves reliability by minimizing the number of discrete operations required to achieve three-dimensional connectivity.

Inventive Principle:
Principle #5Merging (Combining)
