Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If sensor data is collected and stored locally in the vehicle, then data accessibility and monitoring capabilities are improved, but device complexity and storage requirements increase
Solution Approach 1:
The patent introduces a mobile device as an intermediary between vehicle sensors and remote systems. This mobile device collects sensor data locally, manages storage, and handles wireless transmission, thereby improving data accessibility without significantly increasing overall system complexity. The mobile device acts as a mediator that simplifies the architecture by consolidating multiple functions in a single portable unit.
2Productivity
If wireless transfer of sensor data is implemented, then data transfer efficiency and remote accessibility are improved, but energy consumption and communication costs increase
Solution Approach 1:
The system dynamically adjusts data transfer operations based on various conditions such as vehicle motion state, network availability, and power levels. Data transmission is optimized to occur during appropriate moments (e.g., when vehicle is stationary or in low-motion states), thereby improving transfer efficiency while minimizing unnecessary energy consumption from continuous transmission operations.
3Reliability
If multiple sensor data streams are consolidated and managed, then monitoring capabilities and evidentiary value are improved, but data processing complexity and storage requirements increase
Solution Approach 1:
The mobile device performs multiple functions including data collection from various sensors, consolidation of data streams, local storage management, wireless transmission, and user interface operations. By consolidating these diverse functions into a single multi-functional device, the system improves reliability and evidentiary value without proportionally increasing overall system complexity.
4Ease of operation
If automatic interface with vehicle electronics is implemented, then ease of operation and user convenience are improved, but device complexity and interface requirements increase
Solution Approach 1:
The mobile device automatically interfaces with vehicle electronics without requiring manual user configuration. The system self-configures connections, automatically begins data collection when placed in the vehicle, and manages data operations autonomously. This self-service capability greatly improves ease of operation while keeping the interface simple for users.

AI summary
A device may store and transmit data collected from sensors within a vehicle. The device may include at least one communication interface; a memory configured to store instructions; and a processor, coupled to the at least one communication interface and the memory. The processor may be configured to execute the instructions stored in the memory. The instructions may cause the processor to receive an initiation signal from an on-board interface associated with a vehicle, establish communications with the on-board interface and at least one vehicle sensor in response to the initiation signal, receive a first data stream from the at least one vehicle sensor, generate a second data stream from the least one internal sensor, combine the first data stream and the second data stream into a combined stream, store the combined stream in the memory, and wirelessly transmit the combined stream to a remote storage and retrieval system.
