Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual coding is used for script changes, then the gateway can process various data formats, but the labor cost and deployment time increase significantly
Solution Approach 1:
The patent uses template scripts that can be copied and reused for different data formats. Instead of writing custom scripts for each format, the system provides pre-defined template scripts that can be instantiated multiple times with different parameters, dramatically reducing the labor cost of adapting to new data formats while maintaining versatility
Solution Approach 2:
The patent enables dynamic parameter configuration in template scripts, where users can modify parameters such as data source, data format type, and destination without changing the script structure. This allows the same template script to handle multiple data formats by simply changing parameters, improving both adaptability and deployment efficiency
2Productivity
If single-time programming is used, then the gateway can be deployed quickly initially, but flexibility and adaptability to changing scenarios are reduced
Solution Approach 1:
The patent implements dynamic script configuration where template scripts can be selected, modified, and reconfigured at runtime based on changing IoT scenarios. The system allows users to switch between different template scripts and adjust their parameters dynamically, maintaining fast deployment while enabling flexibility for scenario changes
Solution Approach 2:
The patent creates universal template scripts that can serve multiple functions across different scenarios. A single template script can be configured to handle various data formats, sources, and destinations, making the gateway adaptable to changing requirements without requiring complete reprogramming, thus maintaining both deployment speed and flexibility
3Ease of operation
If custom code writing is required for low-code platforms, then specific functions can be implemented, but labor cost increases and simplicity is reduced
Solution Approach 1:
The patent segments the script development process into two distinct layers: template script definition (handled by the system) and parameter configuration (handled by the user). This segmentation allows users to work with simple parameter settings rather than writing complex code, reducing labor cost and maintaining simplicity while still enabling customized functionality through parameter combinations

AI summary
Disclosed are a script variable binding method and an IoT gateway (110) using the same. The method includes the following steps. A data property and a data source of an input tag (Ta1, Ta2, Ta6, Ta8, Ta9) are defined. When the logic script (SC, SC2, SC3) is executed, a script input variable (32, IP1, IP6, IP7, IP8, IP9) is extracted from source data (SD1, SD2, SD3, SD4) provided by an IoT device according to the data property and the data source of the input tag (Ta1, Ta2, Ta6, Ta8, Ta9). When the logic script (SC, SC2, SC3) is executed, a script output variable (33, OP4, OP5, OP7, OP10) is generated based on computational logic of the logic script (SC, SC2, SC3) and the script input variable (32, IP1, IP6, IP7, IP8, IP9) corresponding to the input tag (Ta1, Ta2, Ta6, Ta8, Ta9).
