Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If each application runs independently with separate data querying and event calculation, then each application can function autonomously, but energy consumption increases and processing efficiency decreases
Solution Approach 1:
The patent merges data querying and event calculation operations across multiple applications into a unified process. A single data query serves multiple applications simultaneously, and event calculations are shared rather than duplicated. This consolidation directly reduces energy consumption by eliminating redundant sensor wake-ups and processing operations, while improving productivity through more efficient resource utilization.
Solution Approach 2:
The system implements universal data querying and event calculation mechanisms that serve multiple applications simultaneously. Instead of dedicated processing for each application, a universal processing layer handles requests from multiple applications using shared sensor data and common calculation logic, reducing overall system energy consumption while maintaining application autonomy.
2Measurement precision
If filtering and noise reduction are performed for each application individually, then each application receives optimized data, but processing time and memory capacity are wasted
Solution Approach 1:
The patent combines filtering and noise reduction operations into a single shared processing step that prepares data for multiple applications simultaneously. Instead of applying filters separately for each application, a unified filtering mechanism processes sensor data once and distributes the cleaned data to all requiring applications, maintaining measurement precision while eliminating redundant processing time and memory usage.
3Adaptability or versatility
If applications require data from different sensors with different bandwidths and readout rates, then each application meets its algorithm requirements, but system complexity increases
Solution Approach 1:
The patent introduces an intermediary data management layer that acts as a mediator between sensors and applications. This intermediary layer handles the complexity of different sensor bandwidths and readout rates by implementing a unified data distribution mechanism that translates diverse sensor outputs into application-compatible formats, reducing system complexity while maintaining adaptability to various application requirements.
4Reliability
If adding or removing applications requires complete revalidation of control software, then system reliability is maintained, but development flexibility is reduced
Solution Approach 1:
The patent segments the control software into modular components with clearly defined interfaces and validation scopes. Instead of requiring complete revalidation when applications are added or removed, only the specific modular components affected by changes need validation. This segmentation maintains system reliability through targeted validation while enabling flexible application management and faster development cycles.
