Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual code modifications are made in sensor nodes to change sensing applications, then sensing conditions can be adjusted, but system complexity and time consumption increase
Solution Approach 1:
The patent introduces a data sink as an intermediary component that stores multiple sensing condition sets and transmits them to sensor nodes. This mediator handles the complexity of code modifications centrally, allowing sensor nodes to adapt to different sensing applications by receiving pre-configured condition sets without manual code changes, thus resolving the contradiction between adaptability and device complexity
Solution Approach 2:
The patent creates copies of sensing condition configurations stored in the data sink and transmits them to sensor nodes as needed. Instead of modifying original codes in each sensor node, the system generates and distributes copied configuration sets, enabling flexible adaptation while maintaining the integrity and reusability of the base code across all nodes
2Adaptability or versatility
If manual code modifications are made in sensor nodes to change sensing applications, then sensing conditions can be adjusted, but time consumption increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring multiple sensing condition sets in the data sink before they are needed. When sensing application changes are required, the system simply transmits pre-prepared condition sets to sensor nodes, eliminating the time-consuming process of manual code modification and enabling rapid adaptation to different sensing scenarios
Solution Approach 2:
The system creates and distributes copied configurations from the data sink to sensor nodes, allowing instant deployment of new sensing conditions without time-consuming manual code changes. This copying mechanism enables parallel preparation and transmission of multiple condition sets, significantly reducing the time required for sensing application transitions
3Adaptability or versatility
If applications in data sink are changed to process different sensing results, then information types can be adjusted, but sensor node configuration complexity increases
Solution Approach 1:
The data sink serves as an intermediary that manages the complexity of handling different information types. It stores multiple sensing condition sets corresponding to different information types and transmits appropriate conditions to sensor nodes, allowing the system to adjust information types without increasing sensor node configuration complexity
Solution Approach 2:
The patent implements universality by designing sensor nodes with a unified configuration interface that can receive and execute different sensing condition sets from the data sink. This multi-functional approach allows the same sensor node hardware and base code to handle various information types by simply changing the transmitted condition parameters, eliminating the need for separate configurations for each information type
