Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems face challenges in achieving bi-directional data flow without performance degradation, particularly in wireless communication systems, due to uni-directional data paths within semiconductor packages, which can lead to congestion and increased processing complexity with the addition of advanced technologies like antenna arrays and beamforming.
Innovation Solution
The solution involves arranging electrical devices as mirrored versions with data flows that are substantially opposite to each other, allowing for efficient interconnection and routing on a printed circuit board (PCB) or package, reducing congestion and enhancing multi-directional signal processing capabilities.

Engineering Contradiction Analysis
1Productivity
If multiple ASIC or FPGA devices are added to process multi-directional data flows, then data processing capability is improved, but device complexity and routing congestion increase
Solution Approach 1:
The patent applies asymmetry by rotating semiconductor dies by specific angles (e.g., 90 degrees) relative to each other on the substrate. This asymmetric arrangement allows data paths to flow in opposite directions through different dies without interfering with each other, enabling bi-directional data flow while maintaining organized routing. The asymmetric orientation of dies eliminates the need for complex routing schemes that would be required with symmetric placements.
Solution Approach 2:
The patent utilizes the spatial dimension by arranging multiple semiconductor dies in different orientations on a single substrate. Instead of adding more dies in a linear fashion which would increase routing complexity, the solution distributes dies across the substrate plane with specific angular relationships, effectively using two-dimensional space to manage data flow directions and reduce routing congestion.
2Productivity
If semiconductor die geometries are shrunk to increase integration, then processing performance is improved, but heat density and signal interference increase
Solution Approach 1:
By rotating dies asymmetrically on the substrate, the patent creates spatial separation between data paths of opposite directions. This asymmetric layout reduces signal interference between adjacent dies while maintaining high integration density, as the angular separation provides natural isolation between signal paths without requiring additional shielding or spacing.
3Ease of operation
If data paths are made bi-directional within a package, then routing efficiency is improved, but control flow congestion occurs
Solution Approach 1:
The patent segments the data processing function across multiple independent semiconductor dies, each handling specific data flow directions. By dividing the system into separate dies with dedicated data paths, the patent avoids control flow congestion that would occur in a single integrated bi-directional path, while maintaining routing efficiency through direct connections on the substrate.
