Innovation Solution
A portable display apparatus with a self-standing housing, digital display screen, and rechargeable battery, which is weatherproof and wind-resistant, allowing for wireless media updates and sensor integration, enabling flexible placement and data collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LED display screens are used for advertising, then flexibility in displaying messages is improved, but power requirement limits mobility and installation locations
Solution Approach 1:
The patent replaces the traditional mains power supply system with a rechargeable battery system. This substitution eliminates the need for electrical outlets and power cables, enabling the display device to be freely positioned and moved without being constrained by power infrastructure. The battery-powered digital display unit can be placed anywhere in the stadium while maintaining full display functionality.
2Adaptability or versatility
If flat LED displays are installed outdoors, then digital display capability is improved, but wind resistance is worsened
Solution Approach 1:
The patent employs a curved or rounded housing design for the digital display unit rather than a flat panel. This curved configuration allows wind to flow smoothly around the device, reducing wind resistance and preventing the display from acting like a sail. The rounded edges and contours enable the display to withstand outdoor windy conditions while maintaining its digital display functionality.
3Ease of operation
If A-frames are used for advertising, then simplicity and stability are improved, but ease of updating messages is worsened
Solution Approach 1:
The patent replaces the manual chalkboard or printed graphic system with a digital display screen controlled by a microprocessor. This allows messages to be updated electronically by sending data through a communication interface, eliminating the need to physically replace display faces or manually write messages. The stable A-frame structure is retained while the messaging system becomes digitally updatable.
4Adaptability or versatility
If permanent LED display installation is implemented, then display functionality is improved, but installation cost and visual limitations are worsened
Solution Approach 1:
The patent divides the display system into a portable, self-contained unit that combines the display screen, battery power supply, and housing into a single movable module. This segmented design eliminates the need for permanent installation infrastructure such as mounting structures, electrical wiring, and fixed support systems. The display unit can be independently positioned and relocated as needed, significantly reducing installation costs while maintaining full display functionality.
