Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If sensor devices are made smaller and cheaper, then deployment scalability is improved, but processing power and memory capabilities deteriorate
Solution Approach 1:
The patent segments the operating system into modular components that can be selectively included or excluded. This allows the OS to be customized for different device capabilities, enabling small, cheap sensor devices to run a lightweight OS with only essential components, while larger devices can include additional components for enhanced functionality.
Solution Approach 2:
The patent implements dynamic OS generation where the operating system is adapted at runtime or deployment time based on the specific hardware constraints and application requirements. This dynamic adaptation allows the same base OS to be optimized for different device configurations, from minimal sensor nodes to more capable gateway devices.
2Adaptability or versatility
If processing power and memory are increased in sensor devices, then application functionality is improved, but power consumption increases
Solution Approach 1:
The patent extracts and removes unnecessary OS components based on specific application requirements and hardware constraints. By taking out only the essential components needed for the application and device capabilities, the OS size and resource consumption are minimized, allowing adequate functionality with reduced power consumption.
Solution Approach 2:
The patent changes the parameters of the operating system by dynamically adjusting its composition, size, and resource allocation based on application requirements and hardware constraints. This parameter optimization ensures that the OS uses processing power and memory efficiently, matching the actual needs of the application rather than providing fixed over-provisioned resources.
3Reliability
If wireless communication capabilities are enhanced in sensor devices, then data transmission quality is improved, but burden on power supply increases
Solution Approach 1:
The patent applies partial action by including only the communication components and protocols necessary for the specific application requirements. Rather than implementing full-featured communication stacks, the OS includes only the minimal set of communication capabilities needed, reducing power consumption while maintaining adequate transmission quality for the application's data rate and reliability requirements.
4Productivity
If operating system is customized for specific applications, then resource efficiency is improved, but system complexity increases
Solution Approach 1:
The patent performs preliminary action by pre-defining a library of OS components and templates that can be automatically selected and assembled based on application requirements and hardware constraints. This preliminary preparation of component libraries and assembly rules simplifies the customization process, allowing efficient resource allocation without manual configuration complexity.
