Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple chips are connected in series with a single power supply, then the deployment process is simplified and cost is reduced, but the voltage consistency between chips deteriorates
Solution Approach 1:
The patent introduces a voltage regulation module as an intermediary component between chips in the series connection. This module actively monitors and adjusts voltage levels to maintain consistency across all chips, resolving the voltage inconsistency problem while preserving the simplified series architecture
Solution Approach 2:
The patent employs dynamic parameter adjustment through voltage regulation modules that continuously monitor and modify voltage parameters. By changing voltage parameters in real-time based on actual chip needs, the system maintains voltage consistency without requiring complex deployment procedures
2Manufacturing precision
If auxiliary power supplies are added to each chip to ensure communication voltage, then voltage consistency is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent merges the power supply function into a centralized series connection architecture with shared voltage regulation. Instead of separate auxiliary power supplies for each chip, the system combines power distribution into a unified structure that reduces component count while maintaining voltage consistency through the voltage regulation module
Solution Approach 2:
The voltage regulation module serves multiple chips simultaneously, providing a universal solution for voltage consistency. This multi-functional component replaces numerous individual auxiliary power supplies, reducing overall system complexity while ensuring each chip receives appropriate voltage levels
3Reliability
If signal level conversion devices are added between chips, then communication reliability is improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The voltage regulation module acts as an intermediary that simultaneously handles both voltage regulation and signal level conversion functions. This single intermediary component ensures communication reliability between chips with different voltage levels without requiring separate signal conversion devices, thereby reducing overall component count
