Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If WiFi wireless communication network is used to transmit control signals, then data transmission ability is improved, but power consumption increases and electromagnetic radiation becomes serious
Solution Approach 1:
The electric energy supply device is designed to perform multiple functions: it not only supplies power to lighting devices but also acts as a data bridge for transmitting control signals between different wireless communication networks (e.g., between ZigBee and WiFi networks). This multi-functionality allows the system to use low-power protocols for control while maintaining the ability to transmit data when needed, thus resolving the contradiction between data transmission capability and power consumption.
2Loss of information
If WiFi wireless communication network is used, then data transmission ability is improved, but cost is significantly increased
Solution Approach 1:
The electric energy supply device serves as a multi-functional unit that combines power supply and data bridging capabilities. By enabling different wireless networks to communicate through this device, the system can use cost-effective low-power protocols for most control operations while maintaining WiFi connectivity only when high data transmission ability is required, thus reducing overall system cost while preserving data transmission capability.
3Loss of information
If WiFi wireless communication network is used, then data transmission ability is improved, but coverage range is limited
Solution Approach 1:
The electric energy supply device acts as an intermediary or relay node between different wireless communication networks. It receives control signals from one network (e.g., ZigBee with broader coverage) and forwards them to the target device through another network (e.g., WiFi for high data transmission ability), or vice versa. This intermediary function effectively extends the coverage range by combining the strengths of different communication protocols.
4Ease of operation
If conventional wireless lighting control system is used, then lighting devices can be controlled, but utilization rate is low because devices are idle most of the time
Solution Approach 1:
The electric energy supply device is designed as a multi-functional unit that not only controls lighting devices but also serves as a data bridge for various other wireless communication tasks. This allows the system to remain active and useful even when lighting control is not needed, as the device can continue to relay control signals for other devices or networks, thereby significantly increasing the utilization rate while maintaining ease of operation.
5Ease of operation
If conventional wireless lighting control system is used, then lighting devices can be controlled, but flexibility is limited to only lighting control
Solution Approach 1:
The electric energy supply device is designed with universal multi-functionality, enabling it to control not only lighting devices but also other types of devices through its data bridge capability. By supporting multiple wireless communication protocols and acting as a relay between different networks, the system gains flexibility to control various devices (e.g., appliances, security systems) while maintaining ease of operation through a unified interface.
