Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If HBM is offset from ASIC due to IC size mismatches, then adaptability to various IC sizes is improved, but signal transmission efficiency deteriorates
Solution Approach 1:
The patent segments the HBM connector into multiple sections with different offset capabilities. Each segment can be independently configured to handle specific offset distances, allowing the system to adapt to various IC size variations while maintaining optimal signal transmission paths for each segment.
Solution Approach 2:
The patent implements dynamic offset adjustment mechanisms that allow the HBM connector to adapt its configuration based on the specific ASIC size and positioning requirements. This dynamic adaptability enables the system to maintain signal transmission efficiency across different offset distances by adjusting connector geometry and routing paths in real-time.
2Adaptability or versatility
If HBM offset is extended to accommodate IC size variations, then adaptability is improved, but routing complexity increases
Solution Approach 1:
The patent designs a universal HBM connector structure that can handle multiple offset configurations through a single standardized interface. This multi-functional connector incorporates adjustable routing paths and reconfigurable connection points, allowing it to accommodate various IC sizes without requiring multiple specialized connector designs, thereby managing routing complexity.
Solution Approach 2:
The patent employs nested routing structures where multiple signal paths are embedded within a compact connector geometry. The nested design allows different routing options to be contained within the same physical space, enabling extended offset accommodation while maintaining compact form factor and managing routing complexity through hierarchical organization of signal paths.
3Adaptability or versatility
If connector distance is increased to cover broader offsets, then offset accommodation is improved, but wire length increases leading to higher power consumption
Solution Approach 1:
The patent applies local quality optimization by varying connector and wire characteristics at different offset positions. Rather than using uniform wire and connector designs throughout, the system employs locally optimized structures that minimize wire length and resistance for each specific offset distance, thereby reducing power consumption while maintaining broad offset coverage capability.
Solution Approach 2:
The patent transitions from linear wire routing to three-dimensional routing paths that utilize vertical and lateral dimensions. By routing signals through multiple dimensions rather than simple linear extensions, the system achieves broader offset coverage with minimized wire lengths, reducing resistance and power consumption while maintaining adaptability to various offset distances.
