Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If DALI standard communication is used for illumination control, then light adjustment control functionality is improved, but communication network quality diagnosis capability deteriorates
Solution Approach 1:
The semiconductor device is divided into functional modules: a communication interface module for DALI standard communication and a separate deterioration detector for monitoring communication quality. This segmentation allows the device to simultaneously perform light control functions and communication quality diagnosis without interference between functions.
Solution Approach 2:
A deterioration detector is introduced as an intermediary component that monitors the communication interface module's performance. This detector analyzes communication data waveforms and generates deterioration information, enabling indirect assessment of communication network quality without disrupting the primary control functions.
2Reliability
If communication network quality diagnosis is implemented, then network reliability is improved, but device complexity increases
Solution Approach 1:
The deterioration detector is designed with multi-functionality: it detects communication quality, generates deterioration information, and can trigger maintenance alerts. By consolidating these related functions into a single component, the device achieves comprehensive monitoring capability without proportionally increasing complexity.
Solution Approach 2:
The communication interface module and deterioration detector work together in a self-monitoring system where the device automatically assesses its own communication quality and generates diagnostic information without requiring external monitoring equipment, thereby improving reliability while minimizing additional complexity.
