Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed current setting resistor is used in the lighting module, then the driver circuit can be simplified and existing drivers can be used, but the user cannot adjust the current and light output to meet different application needs
Solution Approach 1:
The lighting module provides its own configuration capability through an integrated resistor circuit and control interface. The module can be configured wirelessly via NFC to set the output resistance, enabling users to adjust current settings without requiring driver modification or complex external components. The module serves itself by incorporating the configuration functionality directly into the module rather than relying on the driver for adjustment capabilities.
Solution Approach 2:
The configuration functionality is segmented into a separate resistor circuit and control interface that can be independently configured. The resistor circuit is controlled by a control circuit that receives configuration information from external devices via NFC, allowing the resistance value to be adjusted without affecting the driver circuit design. This segmentation enables flexible current setting while maintaining driver simplicity.
2Ease of operation
If wireless NFC configuration is integrated into the lighting module, then user configuration becomes easier and more flexible, but the module requires additional control interface and power supply components
Solution Approach 1:
The NFC control interface serves multiple functions: it provides wireless configuration capability for setting the resistor circuit value, enables remote programming of the lighting module parameters, and maintains compatibility with existing driver architectures. The integrated power supply circuit also serves dual purposes by powering both the control interface and the resistor circuit, reducing the need for separate power components.
Solution Approach 2:
The control interface and power supply are merged into a single integrated unit within the lighting module. The power supply circuit is designed to power both the NFC control interface and the resistor circuit simultaneously, reducing component count and simplifying the overall module architecture. The control circuit integrates the NFC reception, processing, and resistor control functions in one unit.
3Adaptability or versatility
If the output resistance is settable within the lighting module, then users can optimize lighting for different applications without changing drivers, but the resistor circuit requires precise control and configuration mechanisms
Solution Approach 1:
The control circuit receives configuration information from external devices via NFC and uses this feedback to adjust the resistor circuit output resistance to the desired value. The system establishes a feedback loop where the configured resistance value is communicated back to the driver, enabling precise control of the output current while maintaining simplicity in the overall control architecture.

AI summary
A solid state lighting module comprises a light source and a resistor circuit, wherein an output resistance of the resistor circuit is for conveying to a connected driver information on a desired power to be applied to the solid state light source. A control interface is provided for receiving configuration information from an external configuration device; and a control circuit configures the resistor circuit thereby to set the output resistance in response to received configuration information. This approach involves integrating the configuration function in the lighting module instead of in the driver. The output resistance can be determined by existing driver architectures without modification, while at the same time the ability of the user to tailor individual lighting modules to their needs is enabled.
