Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a satellite mobile communication device uses a traditional bulky setup to achieve appropriate communication effect, then communication performance is improved, but volume and cost increase
Solution Approach 1:
The patent divides the satellite communication device into multiple functional modules: control circuit board, antenna modules, connection modules, and housing components. Each module is independently designed and can be separately manufactured and assembled, reducing overall device volume while maintaining communication performance
Solution Approach 2:
The patent employs three-dimensional arrangement of antenna modules in vertical and horizontal dimensions, allowing compact integration of multiple antennas within a small footprint. The antenna modules are positioned at different heights and angles to achieve optimal signal reception without increasing device volume
2Reliability
If a satellite mobile communication device uses a traditional bulky setup to achieve appropriate communication effect, then communication effect is improved, but manufacturing cost increases
Solution Approach 1:
By segmenting the device into standardized modules (control circuit board with antenna modules, connection modules, housing), each module can be mass-produced using standardized manufacturing processes, reducing per-unit costs through economies of scale
Solution Approach 2:
The control circuit board is designed to support multiple antenna modules with different functions (signal reception, positioning, communication). This multi-functional design allows a single control unit to manage various communication tasks, reducing the need for separate specialized components and lowering overall manufacturing cost
3Productivity
If multiple antenna modules are arranged in three-dimensional space to determine optimal receiving antenna, then communication efficiency is improved, but device complexity increases
Solution Approach 1:
The control circuit dynamically selects and switches between different antenna modules based on real-time signal quality assessment. The system can adaptively adjust which antenna is active, creating a dynamic antenna selection mechanism that improves communication efficiency without requiring permanent complex multi-antenna configurations
Solution Approach 2:
The control circuit continuously monitors signal strength and quality from different antenna modules and uses this feedback to determine the optimal receiving antenna. This feedback mechanism enables automatic antenna selection and switching, improving communication efficiency while keeping the control logic manageable through algorithmic decision-making
