Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If professional mobile devices operate on TETRA standard with dedicated terminals, then reliability and safety features are ensured, but application capabilities and technological development are limited
Solution Approach 1:
The patent introduces a dual-mode terminal that acts as an intermediary between TETRA professional networks and public cellular networks. This terminal includes both TETRA communication module and public network communication module, enabling users to access advanced applications on public networks while maintaining reliable TETRA network connectivity for professional communications
Solution Approach 2:
The terminal is designed with multi-functionality to operate on both TETRA professional networks and public cellular networks. It can switch between different communication modes and networks, providing both the reliability of dedicated professional terminals and the versatility of consumer smartphones
2Device complexity
If TETRA terminals are designed for simple communication functions, then device complexity is reduced and reliability is improved, but advanced data services and high-value applications cannot be supported
Solution Approach 1:
The terminal architecture is segmented into distinct functional modules: TETRA communication module for professional reliable communications, public network communication module for advanced data services, and switching control module. This segmentation allows each module to be optimized for its specific function while working together to provide comprehensive capabilities
3Reliability
If dedicated TETRA terminals are manufactured with proprietary closed systems, then system reliability is maintained, but third-party application development and technological innovation are restricted
Solution Approach 1:
The terminal merges two previously separate systems into one unified device: the reliable TETRA professional communication system and the versatile public cellular network system with open application ecosystem. This combination allows users to benefit from both the reliability of dedicated professional terminals and the application flexibility of consumer smartphones
