Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wireless circuits and antennas are installed to support various communication services, then communication versatility is improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent implements a universal wireless communication unit that can perform multiple communication functions (LTE, Wi-Fi, Bluetooth, etc.) using a single integrated circuit and antenna system. The communication method determination unit dynamically selects appropriate communication methods based on vehicle state, allowing one hardware system to serve multiple communication purposes without requiring separate dedicated circuits for each service type.
Solution Approach 2:
The system dynamically determines which communication method to use based on real-time vehicle state information (ignition state, door lock state, etc.). The communication method determination unit continuously monitors vehicle conditions and switches between different communication methods (LTE, Wi-Fi, Bluetooth) as needed, making the system adaptive rather than static.
2Reliability
If multiple dedicated wireless circuits and antennas are used for each communication service, then communication reliability is improved, but space and weight increase
Solution Approach 1:
A single wireless communication unit serves as a multi-functional platform that can reliably perform LTE, Wi-Fi, Bluetooth, and other communication services. By consolidating multiple dedicated circuits into one universal unit, the system maintains communication reliability while significantly reducing the total number of components and overall device weight.
Solution Approach 2:
The patent merges multiple separate wireless communication circuits and antennas into a single integrated wireless communication unit. This consolidation combines the functions of what would traditionally require separate dedicated hardware for each communication service, reducing component count and weight while maintaining the reliability needed for various communication tasks.
3Adaptability or versatility
If multiple separate wireless communication units are installed for different services, then communication functionality is improved, but manufacturing costs increase
Solution Approach 1:
The universal wireless communication unit is designed to support multiple communication services (LTE, Wi-Fi, Bluetooth, etc.) through a single integrated circuit, eliminating the need to manufacture and assemble multiple separate communication units. This approach reduces part numbers, simplifies supply chain management, and lowers overall manufacturing costs while maintaining full communication functionality.
Solution Approach 2:
The patent combines multiple wireless communication functions into a single integrated unit, reducing the total number of components that need to be manufactured and assembled. This consolidation decreases manufacturing complexity and cost while preserving all necessary communication capabilities through the multi-functional design.
