Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple commands or signals are transmitted to individually control a plurality of lighting devices, then each lighting device can be controlled accurately, but operation lag and delay occur
Solution Approach 1:
The patent merges multiple individual control commands into a single collective control signal. Instead of transmitting separate commands to each lighting device, the system transmits one unified signal that contains coordinate information and control parameters, enabling all devices to self-organize and respond simultaneously, thereby eliminating operation lag while maintaining control accuracy.
Solution Approach 2:
The patent implements preliminary action by pre-mapping lighting devices to coordinate values in a coordinate system before control execution. This pre-arranged mapping allows devices to automatically determine their positions and responses based on the collective control signal, eliminating the need for real-time individual addressing and reducing transmission delay.
2Measurement precision
If multiple commands are transmitted to control each lighting device individually, then precise control is achieved, but communication load increases
Solution Approach 1:
The patent combines multiple individual control data packets into a single collective control signal. The control signal includes a collective control parameter that applies to all lighting devices, along with coordinate information that enables each device to self-identify its position and response, dramatically reducing the total data quantity transmitted while maintaining precise control.
Solution Approach 2:
The patent creates a universal control signal structure that serves multiple functions simultaneously: it provides collective control parameters for all devices, includes coordinate mapping information for position identification, and enables individual device response determination. This multi-functional approach eliminates the need for separate control messages for each device.
3Adaptability or versatility
If multiple individual control signals are transmitted, then each device can be controlled independently, but processing speed decreases
Solution Approach 1:
The patent performs preliminary action by pre-establishing the coordinate mapping between lighting devices and their positions in the coordinate system. This pre-configuration enables devices to independently determine their own control parameters from the collective control signal without requiring sequential processing, thereby maintaining independent control capability while achieving parallel processing and high-speed response.
Solution Approach 2:
The patent implements self-service by enabling each lighting device to autonomously determine its position and control response based on the coordinate information contained in the collective control signal. Each device independently processes the signal according to its mapped coordinates, eliminating the need for centralized sequential processing and significantly increasing overall system processing speed.
