Solution Overview
Problem
Existing data storage and transfer methods, such as USB sticks, are cumbersome and prone to loss, exposing data to security risks, and communication between devices without internet access is inefficient, especially in vehicles with limited computing capacity.
Innovation Solution
A portable storage system integrated with vehicle locking and control systems, featuring a processor, storage module, and wireless communication, allowing direct device-to-device communication via standardized communication protocols like Bluetooth or NFC, enabling secure data transfer without networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If USB sticks are used for data storage and transfer, then data can be transferred between devices, but the devices are easily misplaced and left behind, exposing data to security risks
Solution Approach 1:
The patent combines the storage device with a key fob that integrates multiple functions including wireless communication capabilities (Bluetooth, NFC), vehicle access control, and data storage. This merging eliminates the need to carry separate USB sticks while maintaining data security through integrated authentication mechanisms.
Solution Approach 2:
The key fob storage device serves multiple purposes: it acts as a vehicle key, provides wireless communication for data transfer, stores data locally, and enables vehicle access and control. This multi-functionality replaces several separate devices with one unified solution.
2Reliability
If Bluetooth enabled devices are used for direct communication, then communication can occur without internet access, but the devices must be within limited range and communication speeds are relatively slow
Solution Approach 1:
The system dynamically selects communication protocols based on requirements: Bluetooth for short-range direct communication, NFC for contactless data exchange, and wireless internet for high-speed transfers. This dynamic adaptation optimizes communication speed for different scenarios while maintaining reliability.
Solution Approach 2:
The key fob acts as an intermediary device that can store data locally and transfer it to vehicles or other devices through multiple communication channels, bridging the gap between devices with different communication capabilities and ranges.
3Reliability
If files are transferred without internet connection, then data security is improved, but it is difficult to transfer files without using data on a data plan or network access
Solution Approach 1:
The key fob contains local storage capacity and can autonomously store and manage files, enabling direct peer-to-peer transfers between vehicles and devices without requiring network infrastructure or data plans. The device serves itself as both storage medium and communication interface.
4Device complexity
If older ECUs are used in vehicles, then vehicle systems are simpler, but they have limited computing capacity and cannot support modern electronic conveniences
Solution Approach 1:
Instead of upgrading the vehicle's internal ECU (horizontal dimension), the patent adds an external computing dimension through the key fob device that connects wirelessly to the vehicle. This externalizes computing power while preserving the simplicity of older vehicle systems.
Solution Approach 2:
The key fob serves as an intermediary computing device that bridges modern processing capabilities with older vehicle systems. It handles complex computations externally and communicates results to the vehicle's simpler ECU, enabling modern features without upgrading the vehicle's internal hardware.
