Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle manufacturers design vehicles with built-in wireless connections and battery monitoring systems, then battery data can be monitored and communicated to on-board computers and cloud networks, but add-on or after-market components have little to no access to vehicle parameters and wireless communication systems
Solution Approach 1:
The patent introduces an intermediary device that connects to the vehicle's OBD port and acts as a bridge between the vehicle's restricted communication systems and external add-on components. This intermediary captures battery data from the vehicle's existing monitoring system and relays it to external devices, thereby providing access without modifying the original restricted architecture.
Solution Approach 2:
The patent segments the communication architecture into multiple independent layers: the vehicle's internal monitoring system, the OBD port interface layer, and external access layers. This segmentation allows different components to access appropriate data levels without requiring full system access, resolving the contradiction between maintaining security/reliability and enabling add-on accessibility.
2Loss of information
If the vehicle's communication system restricts access to battery data, then manufacturer control and data security are maintained, but comprehensive battery health analysis by external systems is limited
Solution Approach 1:
The patent makes the OBD port interface universal by designing it to handle multiple communication protocols and data formats simultaneously. The interface can work with different vehicle manufacturers' systems while providing standardized access to battery parameters, thereby increasing data accessibility without proportionally increasing complexity.
3Reliability
If multiple communication links are used to transmit battery data, then data transmission reliability and accessibility are improved, but system complexity and data routing decisions increase
Solution Approach 1:
The patent implements self-service mechanisms where the communication interface automatically selects and manages data transmission paths based on pre-defined criteria such as link availability, data priority, and transmission success rates. This automation reduces the complexity of manual link management while maintaining high transmission reliability through intelligent routing.
Solution Approach 2:
The system incorporates feedback loops that monitor the status of multiple communication links and dynamically adjust data routing decisions. When one link fails or degrades, the system receives feedback and automatically switches to alternative links, thereby maintaining reliability without requiring complex manual intervention.
