NFC Action Data Exchange for Automatic Role Negotiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current near field communication systems lack a reliable and user-interaction-free method for establishing communication between two intelligent devices, as the selection of initiator and target roles is non-deterministic, leading to uncertainty about the actions to be performed during peer-to-peer communication.
Innovation Solution
The introduction of an action list exchange mechanism, where devices provide action data to each other during initialization, allowing the system to autonomously select and perform actions without user input, by determining device roles and exchanging application directory and action lists.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a non-deterministic role selection method is used in near field communication, then device compatibility and ease of connection are improved, but reliability and determinism of communication actions deteriorate
Solution Approach 1:
The patent applies preliminary action by having the target device provide an action list to the initiator device before the actual communication action is selected and executed. This allows the initiator to know in advance what actions are available and deterministic selection can be made based on predefined criteria, resolving the contradiction between ease of connection and reliability of communication actions.
2Extent of automation
If automatic role assignment is implemented, then user interaction is reduced, but uncertainty about communication actions increases
Solution Approach 1:
The patent implements feedback by having the target device send an action list back to the initiator device after role assignment. This feedback mechanism provides the initiator with information about available actions, eliminating uncertainty while maintaining automatic role assignment and reducing user interaction.
3Extent of automation
If action data is exchanged during initialization, then automatic action selection is enabled, but communication protocol complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the communication setup into distinct phases: initialization where action data is exchanged, and subsequent processing where actions are selected and executed. This segmentation allows automatic action selection without requiring the entire protocol to be complex, as the action list exchange is a separate, standardized step.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces the need for user interaction by enabling automatic negotiation and selection of actions, ensuring reliable and efficient near field communication without manual device selection.
Implementation Method 1
A basic aspect of a near field communication is the usage of electromagnetic waves in radio frequency range and that the transmission of the information content is realized over a short distance only
