Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for configuring devices, particularly in land vehicles and sea crafts, often require complex and expensive wired connections, such as CAN buses, for setting up parameters, which are difficult to handle and prone to data tampering.
Innovation Solution
A method using near field communication (NFC) to configure devices by detecting an active NFC device, transmitting configuration data, and storing it in a configuration data memory, allowing for automatic configuration or immediate operation based on the stored data, while ensuring data security and reducing the need for physical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections like CAN bus are used for device configuration, then configuration data can be transmitted reliably, but the device complexity and cost increase due to additional wiring and connection requirements
Solution Approach 1:
The patent replaces mechanical wired connections (CAN bus, hard-wired data buses) with wireless NFC (Near Field Communication) technology. The NFC module enables configuration data transmission through electromagnetic fields without physical connectors, eliminating the need for complex wiring while maintaining secure and reliable data transfer for device configuration.
2Reliability
If wired connections are used for configuration, then stable data transmission is achieved, but ease of operation deteriorates due to difficult handling and installation
Solution Approach 1:
The patent substitutes mechanical connection operations with contactless NFC communication. Configuration can be performed by simply bringing the NFC device close to the target device, eliminating the need for plugging in connectors or establishing physical data bus connections, thereby dramatically improving ease of operation while maintaining transmission stability.
Solution Approach 2:
The NFC module enables automatic configuration processes where configuration data is transmitted and applied with minimal user intervention. The system can automatically detect configuration parameters, transfer them via NFC, and implement settings without requiring manual wiring or complex setup procedures.
3Reliability
If configuration data is stored locally in firmware, then data security is improved, but adaptability deteriorates when firmware updates are required
Solution Approach 1:
The patent introduces NFC as an intermediary configuration channel that allows secure transmission of configuration data without requiring firmware updates. Configuration parameters can be transferred via NFC and stored in configurable memory, enabling flexible adaptation while maintaining security through controlled access interfaces rather than requiring system-wide firmware changes.
