Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual fuel gauges are installed in each battery, then battery information can be provided for each device, but manufacturing costs significantly increase
Solution Approach 1:
The patent implements a universal gauge master algorithm that can process battery information from multiple different devices (mobile phones, tablets, wearables, etc.) through a single processing circuit. This multi-functional approach eliminates the need for dedicated fuel gauges in each battery, significantly reducing manufacturing costs while maintaining the ability to provide accurate battery information across diverse device types
Solution Approach 2:
The patent combines multiple battery measurement and processing functions into a single integrated processing circuit. Instead of having separate fuel gauge components in each battery, the system merges all battery information processing into one centralized unit that handles multiple batteries across different devices, reducing component quantity and manufacturing complexity
2Reliability
If individual fuel gauges are installed in each battery, then battery information can be monitored, but functionality and quality of each fuel gauge may be inconsistent
Solution Approach 1:
The universal gauge master algorithm provides consistent and standardized battery information processing across all supported devices. By using a single unified algorithm rather than multiple different fuel gauge implementations, the system ensures uniform functionality and quality regardless of the device type or battery characteristics
Solution Approach 2:
The patent employs a homogeneous processing approach where all battery information passes through the same gauge master algorithm in the processing circuit. This ensures consistent measurement standards, data processing methods, and output formats across all batteries, eliminating the variability that would exist with multiple different fuel gauge implementations
3Ease of manufacture
If a universal gauge master algorithm is used to process battery information from multiple devices, then manufacturing costs are reduced, but the processing circuit must handle multiple data streams
Solution Approach 1:
The processing circuit implements segmented processing by creating separate processing channels or modules within the unified gauge master algorithm, where each channel handles battery information from a specific device. This segmentation allows the system to manage multiple data streams efficiently while maintaining a cost-effective single-processing-circuit architecture
