NFC Module for Electrical Device Data Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical devices lack efficient methods for gathering status data and downloading operating parameters, making it difficult for users to monitor and customize device functions, especially in portable and power tool applications.
Innovation Solution
Incorporating a near field communication (NFC) device connected to the control unit, allowing for easy data exchange of status and operating parameters, with a marker on the housing to facilitate user interaction and using a mobile phone as a read/write device for near field and remote communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional data exchange methods are used in electrical devices, then device complexity is reduced, but ease of operation deteriorates due to difficult data gathering and parameter downloading
Solution Approach 1:
The patent extracts the communication functionality into a separate, standardized NFC module that can interact with external devices without requiring complex internal wiring or protocols. This allows easy data exchange through a dedicated communication interface while keeping the main device architecture simple.
Solution Approach 2:
The NFC device provides universal communication capability that can handle multiple functions including status data reading, parameter downloading, and device customization through a single standardized interface, eliminating the need for multiple specialized connection methods.
2Ease of operation
If NFC device is integrated into electrical device, then ease of operation improves for data exchange, but device complexity increases due to additional components
Solution Approach 1:
The NFC device is merged with the control unit or housing structure, allowing the communication functionality to be integrated into existing device components rather than adding completely separate elements, thus minimizing overall device complexity.
Solution Approach 2:
The NFC device acts as an intermediary component that facilitates communication between the electrical device and external devices without requiring direct integration with core functional systems, thereby maintaining system simplicity while enabling enhanced operability.
3Ease of operation
If marker is added to housing to indicate NFC position, then ease of operation improves for user interaction, but manufacturing precision requirements increase
Solution Approach 1:
The marker can be implemented as a visually distinct element (such as a colored ring or printed symbol) that provides clear visual guidance to users without requiring precision mechanical features, thereby reducing manufacturing precision requirements while maintaining ease of interaction.
Solution Approach 2:
The housing surface is segmented into functional zones with the marker indicating the specific NFC interaction area, allowing users to easily identify the correct position without requiring high-precision alignment features in the overall housing structure.
