Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the digital license plate is powered by the vehicle's main power source, then the system can operate with a single power source, but the digital license plate fails to function when the vehicle is in a 'stop' mode
Solution Approach 1:
The patent combines multiple power sources (vehicle battery and secondary backup battery) into a unified power supply system for the digital license plate. The control unit manages power distribution from both sources, ensuring continuous operation regardless of vehicle state. This merging of power sources resolves the contradiction by maintaining operational continuity while managing system complexity through intelligent power management.
Solution Approach 2:
The system changes the operational parameter of power supply configuration based on vehicle state. When the vehicle is running, it uses the main vehicle battery; when stopped, it automatically switches to the secondary backup battery. This dynamic parameter change ensures the digital license plate remains functional across different operational modes, resolving the reliability issue.
2Device complexity
If the digital license plate operates without temperature control, then the system structure remains simple, but the digital license plate malfunctions in extreme weather conditions due to overheating or overcooling
Solution Approach 1:
The patent introduces a thermostat as an intermediary component between the digital license plate and the extreme environmental conditions. The thermostat actively regulates temperature by switching heating or cooling systems on as needed, protecting the digital license plate from overheating or overcooling. This intermediary mechanism resolves the contradiction by maintaining reliable operation in extreme weather while managing system complexity through targeted environmental control.
3Device complexity
If the digital license plate lacks a secondary power source, then the system uses fewer components, but the digital license plate cannot provide continuous messaging capabilities when the vehicle is stopped
Solution Approach 1:
The system performs preliminary action by installing a secondary backup battery in advance, specifically positioned to provide power to the digital license plate when the vehicle is stopped. This pre-configured backup power source ensures that messaging capabilities can continue uninterrupted for extended periods regardless of vehicle operational state, resolving the contradiction between component count and operational duration.
4Device complexity
If the digital license plate lacks temperature monitoring and control, then the system requires fewer components, but the digital license plate is prone to failure in extreme temperatures
Solution Approach 1:
The patent implements a feedback mechanism where a thermostat continuously monitors the temperature environment of the digital license plate and automatically switches heating or cooling systems on as needed. This closed-loop feedback control ensures temperature stability and prevents failure in extreme conditions, resolving the contradiction by maintaining reliable temperature control while managing system complexity through automated regulatory mechanisms.
