Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If prior methods use physical cables and additional hardware to collect key data, then data collection capability is achieved, but device complexity and production costs increase
Solution Approach 1:
The patent introduces a server as an intermediary component that receives key data readings from the external module via wireless communication. The server performs the key data extraction and computer program generation, eliminating the need for complex local hardware processing in the external module. This mediator approach allows the external module to remain simple while achieving reliable data collection and processing through cloud-based resources.
2Reliability
If prior methods require additional hardware in external module, then key data collection is enabled, but manufacturing cost increases
Solution Approach 1:
The patent implements a self-service model where the external module collects key data readings and transmits them wirelessly to a server. The server then performs the computationally intensive tasks of key data extraction and computer program generation. This shifts the service burden from the external module hardware to cloud-based server resources, reducing manufacturing costs for the external module while maintaining reliable key data collection capability.
3Loss of information
If prior methods use physical connection cables, then data transfer is achieved, but security is compromised
Solution Approach 1:
The patent replaces the mechanical cable-based data transfer system with a wireless communication system. The external module communicates key data readings to the server wirelessly, eliminating the need for physical cable connections. This substitution maintains data transfer reliability through wireless protocols while improving system security by removing the physical interface that could be exploited for unauthorized access or data interception.
4Reliability
If prior methods use fixed hardware configuration, then data collection works for current systems, but adaptability to new security technologies is limited
Solution Approach 1:
The patent creates a universal system where the external module has general wireless communication capability to interact with various server implementations. The server side can be updated and configured to handle different vehicle security systems and protocols without requiring hardware changes in the external module. This multi-functional architecture allows the system to adapt to new security technologies through software updates on the server while maintaining reliable data collection functionality.
