Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an outdoor display screen is mounted using an independent cabinet or integrated with bus station/newsstand, then the display screen can be disposed in densely populated areas, but complex engineering construction is required including concrete foundation, pipeline cabling, and mounting fixation
Solution Approach 1:
The patent merges the outdoor display screen with an existing communications device enclosure, eliminating the need for independent cabinet or bus station integration. The display screen is directly mounted on the communications device housing, which already has power and communication infrastructure, thereby reducing engineering construction complexity while maintaining adaptability for dense area deployment
Solution Approach 2:
The communications device enclosure serves multiple functions: it provides structural support for the display screen, houses power supply infrastructure, and contains communication interfaces. This multi-functionality eliminates the need for separate mounting structures and cabling infrastructure, resolving the contradiction between deployment flexibility and construction complexity
2Reliability
If AC power supply and communications channel are specially designed for the outdoor display screen, then the display screen can operate independently, but complex pipeline cabling and mounting fixation are required
Solution Approach 1:
The communications device provides self-service power and communication resources to the display screen through integrated interfaces. The power supply component and communication module within the communications device directly serve the display screen without requiring external AC power infrastructure or separate communication cabling, thereby maintaining reliability while simplifying installation
3Device complexity
If the display screen is integrated with the communications device enclosure, then construction difficulty is reduced, but the heat dissipation system of the communications device may be affected
Solution Approach 1:
The patent segments the heat dissipation system into separate circulation paths: an internal circulation path for the communications device and an external circulation path for the display screen. This segmentation allows independent heat management for each component, preventing the display screen from interfering with the communications device's thermal performance while maintaining integration benefits
