Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional electronic control devices are added to control multiple warning lights, then the coordination of flashing can be improved, but the manufacturing cost and device complexity increase
Solution Approach 1:
The patent combines multiple control functions into a single control device that integrates a control bus and data bus. The control bus transmits control signals while the data bus transmits data, clock, and identity signals, eliminating the need for separate electronic control devices for each warning light and reducing overall system complexity.
Solution Approach 2:
The control device is designed with multi-functionality, serving as both a control unit and a data transmission hub. It can identify each warning light through ID signals, transmit control commands, and synchronize flashing patterns across multiple lights, replacing what would traditionally require multiple dedicated control devices.
2Device complexity
If traditional control methods are used without ID numbers, then the device complexity is reduced, but the control stability and flicker coordination deteriorate
Solution Approach 1:
The patent implements a feedback mechanism where the control device transmits identity signals to each warning light, and the lights respond with their ID numbers. This bidirectional communication enables the control device to accurately identify and control each light individually, ensuring stable control and coordinated flashing without excessive complexity.
Solution Approach 2:
The data bus acts as an intermediary between the control device and warning lights, carrying data, clock, and identity signals. This intermediary structure enables reliable identification and control of multiple lights while maintaining a relatively simple control circuit architecture.
3Manufacturing precision
If multiple separate control devices are used for each warning light, then the control precision is improved, but the manufacturing cost increases
Solution Approach 1:
The patent segments the control functionality by assigning unique ID numbers to each warning light, allowing individual identification and control. However, instead of using separate physical control devices for each light, the segmentation is achieved through software/logic in a single control device that processes ID signals and distributes control commands selectively.
Solution Approach 2:
The patent uses digital copying of control signals through the data bus. The control device can transmit identical or differentiated control commands to multiple lights by copying the base control signal and modifying it based on received ID numbers, achieving precise individual control without replicating entire control devices.
