Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If distinct printed circuit boards are designed for each emergency lighting unit variant, then each unit can have specific operational and control system parameters, but development costs and development time increase
Solution Approach 1:
A single common PCB design is used for multiple emergency lighting unit variants, with the ability to be configured for different operational parameters through NFC programming. This universal board replaces the need for multiple distinct PCB designs, reducing development time while maintaining parameter specificity through software configuration.
Solution Approach 2:
The PCB is designed to accept configurable parameters through NFC technology, allowing operational and control system parameters to be changed via software rather than hardware redesign. This enables the same physical board to adapt to different unit requirements by programming different parameter sets.

A single common PCB design is used for multiple emergency lighting unit variants, with the ability to be configured for different operational parameters through NFC programming. This universal board replaces the need for multiple distinct PCB designs, reducing development time while maintaining parameter specificity through software configuration.
Solution Approach 2:
Instead of creating physical copies of different PCB designs for each variant, the invention uses a single master PCB design that can be replicated and then programmed with different parameters. This digital parameter copying through NFC is more cost-effective than physical PCB redesign and manufacturing for each variant.
3Loss of time
If a common PCB design is used for multiple emergency lighting units, then development time and costs are reduced, but the ability to have specific parameters for each unit is compromised
Solution Approach 1:
The PCB is designed to accept configurable parameters through NFC technology, allowing operational and control system parameters to be changed via software rather than hardware redesign. This enables the same physical board to adapt to different unit requirements by programming different parameter sets.
Solution Approach 2:
NFC technology serves as an intermediary between the common PCB and the specific parameter requirements of different unit variants. The NFC interface enables wireless programming and configuration, allowing the single PCB design to achieve parameter specificity without requiring distinct hardware designs for each variant.
