Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wired camera systems are installed in aircraft, then reliable power supply and structural support are provided, but installation complexity and weight increase
Solution Approach 1:
The patent replaces the traditional mechanical wiring system with a wireless communication system. The camera unit communicates with the surveillance system via wireless signals, eliminating the need for complex electrical wiring while maintaining reliable operation. This substitution resolves the contradiction by removing installation complexity while preserving system reliability through wireless data transmission and power transfer.
Solution Approach 2:
The mounting rail is designed to serve multiple functions simultaneously: it provides structural support for the camera unit, delivers electrical power through integrated power contacts, and enables wireless communication. This multi-functionality consolidates what would otherwise require separate components, reducing installation complexity while maintaining reliable power and data transmission.
2Adaptability or versatility
If cameras are made easily movable and reinstallable, then adaptability improves, but connection reliability and power supply stability may deteriorate
Solution Approach 1:
The camera surveillance system is divided into modular components: a removable camera unit and a fixed mounting rail assembly. The camera unit can be easily detached and reinstalled at different locations along the rail, providing adaptability. The modular design ensures that connection reliability is maintained through standardized interfaces while allowing flexible repositioning.
Solution Approach 2:
The system transitions from a static wired connection to a dynamic wireless connection, allowing the camera unit to move freely along the mounting rail without compromising connection stability. The wireless communication and power transfer maintain reliable connections regardless of the camera's position, enabling easy relocation while preserving connection reliability.
3Loss of time
If wireless communication is implemented, then installation time and weight are reduced, but power transmission reliability may be affected
Solution Approach 1:
The patent replaces traditional electrical wiring with wireless power transmission technology. This elimination of physical wires significantly reduces installation time and removes the weight of extensive wiring harnesses. The wireless power transmission system maintains reliability through advanced signal modulation and error correction, resolving the contradiction between installation efficiency and power transmission reliability.
4Device complexity
If mounting rails serve dual purpose as power rails, then device complexity is reduced, but electrical safety requirements become more stringent
Solution Approach 1:
The mounting rail and power supply rail are merged into a single integrated structure. This consolidation reduces the number of separate components and simplifies the overall system architecture. The integrated design incorporates safety features such as isolated power contacts and grounding mechanisms, reducing electrical safety risks while maintaining the benefits of reduced complexity.
