Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If local data is burned into the light emitting diode driving apparatus during manufacturing, then the data is fixed and reliable, but the data cannot be changed post-manufacturing making warehouse management and assembly inconvenient
Solution Approach 1:
The patent transforms the static, fixed local data storage into a dynamic system by introducing a burning signal detector and controller that can receive wireless burning signals and update the local data in the memory through I2C interface, allowing the data to be modified after manufacturing while maintaining reliability through controlled access
Solution Approach 2:
The patent introduces an intermediary burning signal detector and controller system that mediates between the external wireless burning signals and the internal memory, enabling data updates without requiring physical access to the apparatus or complex verification procedures
2Reliability
If local data is burned into the light emitting diode driving apparatus during manufacturing, then the data integrity is ensured, but careful verification is required for every apparatus to avoid incorrect assembly
Solution Approach 1:
The patent implements a feedback mechanism where the burning signal detector receives wireless burning signals, processes them through a controller, and updates the memory accordingly, providing automatic verification and reducing the need for manual checking by operators
Solution Approach 2:
The system performs self-verification and self-update of local data through the burning signal detector and controller, which automatically validate and write the burning data to memory without requiring external verification procedures
3Ease of operation
If wireless burning signal reception is added to update local data, then data can be changed post-manufacturing improving convenience, but the device structure becomes more complex
Solution Approach 1:
The burning signal detector and controller serve multiple functions: receiving wireless burning signals, converting the signal format, validating the data, and writing to memory through the existing I2C interface, thereby adding data update capability without requiring separate dedicated components for each function
Solution Approach 2:
The patent merges the burning signal detection, signal conversion, and data writing functions into an integrated system that utilizes the existing I2C communication interface and memory structure, combining multiple operations into a unified process that minimizes additional structural complexity
