Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a specific circuit module is designed for each individual sensor type, then the sensor can be interfaced with the RF wireless lighting control system, but the device complexity and design time increase significantly when integrating a variety of sensors
Solution Approach 1:
The patent implements a universal RF interface module that can interface with multiple types of sensors (occupancy sensors, light sensors, temperature sensors, etc.) through a standardized connection. The module includes a microcontroller that can process different sensor protocols and convert them to a unified RF communication format, eliminating the need for separate dedicated modules for each sensor type.
Solution Approach 2:
The RF interface module acts as an intermediary between various sensor types and the RF wireless lighting control system. It provides a standardized interface that translates different sensor protocols into a common format, allowing diverse sensors to communicate through a single universal module rather than requiring specific modules for each sensor type.
2Device complexity
If a universal RF interface module is used for multiple sensor types, then the device complexity is reduced, but power management challenges arise due to varying power requirements of different sensors
Solution Approach 1:
The power management circuit in the universal RF interface module dynamically adjusts power delivery parameters based on the specific sensor type connected and its current operational state. The microcontroller monitors power consumption patterns and modulates voltage and current supply to match the optimal power requirements for each sensor type, reducing overall power consumption while maintaining functionality.
Solution Approach 2:
The module implements periodic power cycling and sleep modes for connected sensors. When no measurement is required, the microcontroller puts sensors into low-power states and periodically唤醒 them for measurements, significantly reducing average power consumption while maintaining measurement capability.

AI summary
A RF wireless sensor interface (20) interfaces one or more of a variety of sensors (12, 13) to a RF wireless network (11). A power converter (30) of the interface (20) converts a primary power (PPRM) into a DC power (PDC) that is supplied to the sensor(s) (12, 13). A microcontroller (60) of the interface (20) receives sensor detection information (SDI) from the sensor(s) (12, 13) in response to the sensor(s) (12, 13) receiving the DC power (PDC) from the power converter (30). A RF transmitter/transceiver (50) of the interface (20) executes a sensor detection information RF transmission (SDIRF) and/or a sensor control signal RF transmission (SCSRF) to the RF wireless network (11) in response to the microcontroller (60) receiving the sensor detection information (SDI). The power converter (30), the microcontroller (60) and the RF transmitter/transceiver (50) are located within a modular housing (80).
