Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrically conductive connections are used for communication between LED module and LED converter, then reliable data transmission is achieved, but the risk of incorrect installation increases
Solution Approach 1:
The patent replaces electrically conductive connections (mechanical/electrical system) with optically conductive connections (optical system). The LED module transmits data optically to the LED converter, eliminating the need for precise electrical contact while maintaining reliable communication. This substitution reduces installation complexity and minimizes incorrect connections.
Solution Approach 2:
The patent introduces an optical intermediary (light signal) to transmit data between the LED module and LED converter. Instead of direct electrical contact, information is conveyed through optical signals that can be transmitted through various media, providing a buffer that reduces the impact of misalignment or incorrect installation.
2Loss of information
If multiple wired connections are provided for communication, then data transmission capability is enhanced, but device complexity increases
Solution Approach 1:
The patent makes the optical communication interface universal by using light signals that can carry multiple types of information (data, status, control signals) through a single channel. The optical receiver can distinguish different signal patterns to extract various information types, eliminating the need for separate wired connections for different communication purposes.
Solution Approach 2:
The patent transitions from electrical domain to optical domain for communication. By using light frequency and modulation techniques, multiple data streams can be transmitted simultaneously through wavelength division multiplexing or time division multiplexing, effectively increasing communication capacity without adding physical connections.
3Adaptability or versatility
If electrically conductive connections are used, then power and data can be transmitted together, but the risk of installation errors increases
Solution Approach 1:
The patent segments the power transmission and data communication functions into separate channels. Power is transmitted through electrical conductors while data is transmitted through optical signals. This segmentation allows each channel to be optimized independently and reduces the risk of installation errors affecting both functions simultaneously.
Solution Approach 2:
The patent uses optical signals as an intermediary for data transmission, separating the data communication path from the power transmission path. This intermediary approach allows power and data to coexist without interfering with each other, reducing installation complexity and improving reliability.
