Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate chips are used for kilohertz and megahertz frequency resonators, then each resonator can be optimized independently, but the overall device size and power consumption increase
Solution Approach 1:
The patent combines both kilohertz and megahertz frequency resonators into a single integrated chip package. The chip includes a first resonator for kilohertz frequency and a second resonator for megahertz frequency, eliminating the need for separate chips and reducing overall device size while maintaining independent optimization of each resonator's performance
Solution Approach 2:
The integrated chip serves multiple functions by housing both timing (kilohertz) and communication (megahertz) frequency resonators in one device. This multi-functional approach allows the single chip to replace what previously required separate components, reducing both size and power consumption while providing comprehensive frequency reference capabilities
2Reliability
If separate chips are used for kilohertz and megahertz frequency resonators, then each resonator can be optimized independently, but power consumption increases
Solution Approach 1:
The patent combines both kilohertz and megahertz frequency resonators into a single integrated chip package. By integrating the resonators on one chip, the system reduces the total power consumption associated with multiple separate devices, while still allowing each resonator to be independently optimized for its specific frequency requirements
Solution Approach 2:
The integrated chip provides both timing and communication frequency references in a single power-efficient device. This multi-functional integration reduces the cumulative power consumption that would result from operating separate kilohertz and megahertz resonator chips independently
3Reliability
If multiple separate components are used for frequency references, then system reliability is improved, but device complexity increases
Solution Approach 1:
The patent merges both kilohertz and megahertz frequency resonators into a single integrated chip, reducing the number of discrete components from two separate chips to one unified device. This integration maintains the reliability benefits of having both frequency references while simplifying the overall system architecture and reducing assembly complexity
