Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual fuel gauges are placed in each battery, then battery information can be monitored, but manufacturing costs significantly increase
Solution Approach 1:
The patent implements a universal gauge master that can monitor multiple batteries across different devices simultaneously. Instead of each battery requiring its own dedicated fuel gauge, a single gauge master processes battery information from multiple sources, making the monitoring system universal and multi-functional across the entire multi-battery system.
Solution Approach 2:
The patent combines multiple individual fuel gauge functions into a single centralized gauge master. By merging the monitoring capabilities into one unified component that handles multiple batteries, the system reduces the total number of fuel gauges needed, thereby lowering manufacturing costs while maintaining comprehensive battery monitoring.
2Reliability
If individual fuel gauges are placed in each battery, then battery monitoring is comprehensive, but functionality and quality become inconsistent
Solution Approach 1:
By using a single universal gauge master for all batteries, the system ensures that every battery is monitored by the same high-quality component with identical functionality and performance characteristics, eliminating quality inconsistencies that would arise from using multiple different fuel gauges.
Solution Approach 2:
The patent creates a homogeneous monitoring system where all batteries are evaluated by the same gauge master with uniform processing algorithms and measurement standards, ensuring consistent quality and reliability across all battery monitoring operations throughout the system.
3Ease of manufacture
If a universal gauge master is used for multiple batteries, then manufacturing cost is reduced, but processing complexity increases
Solution Approach 1:
The gauge master processes battery information in a segmented manner, handling each battery's data through standardized processing stages. This segmentation allows the complex processing to be organized into manageable modules, making the overall system more tractable despite handling multiple batteries simultaneously.
