Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an apparatus and method to manage device operation using near field communication (NFC) as NFC utilization grows, particularly in managing device pairing, orientation, and position-based operations.
Innovation Solution
A device with a memory for storing instructions associated with its orientation and position, and a NFC transceiver for pairing with another device, uses a processor to determine the orientation and position, and executes specific instructions based on these determinations, enabling operations such as pairing, data exchange, and mode switching between peer-to-peer, read/write, and card emulation modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If NFC pairing is implemented between devices, then device connectivity and data exchange capability are improved, but device complexity and management overhead increase
Solution Approach 1:
The system performs preliminary actions by pre-establishing pairing relationships and pre-configuring operation sets associated with specific orientations and positions. When devices are paired via NFC, the pairing information and corresponding operation sets are stored in advance, enabling automatic execution without complex real-time management decisions.
Solution Approach 2:
The system enables self-service through automatic determination of device orientation and position, followed by automatic execution of the corresponding pre-configured operation set. The processor automatically identifies the spatial relationship between devices and executes the appropriate operations without requiring manual intervention or complex management protocols.
2Adaptability or versatility
If orientation and position-based operations are implemented, then context-aware functionality is improved, but measurement and detection difficulty increase
Solution Approach 1:
The system replaces complex mechanical orientation detection with NFC-based identification. Instead of using complex sensors and algorithms to detect device orientation and position, the system uses NFC tags or active NFC devices that store identification information corresponding to different orientations and positions. When devices are paired, the NFC transceiver automatically retrieves the appropriate operation set based on the stored identification information, simplifying the detection process while maintaining context-aware functionality.
3Adaptability or versatility
If multiple operation sets are stored for different orientations and positions, then operational versatility is improved, but memory requirements and device complexity increase
Solution Approach 1:
The system segments the operation sets into distinct groups, each associated with specific orientation and position identification information. Instead of storing all possible operations in a single large data structure, the operations are divided into multiple smaller sets, each triggered by specific NFC-identified conditions. This segmentation reduces the memory footprint of each individual operation set while maintaining overall operational versatility.
Solution Approach 2:
The system implements universality by using a single NFC pairing mechanism that serves multiple functions: establishing connectivity, identifying device orientation and position, and triggering appropriate operation sets. The NFC transceiver and processor work together to handle multiple operational modes (peer-to-peer, read/write, card emulation) through a unified approach, reducing the need for separate memory allocations for each function.

AI summary
A device may include a memory for storing a set of instructions associated with at least one of an orientation and a position of the device. The device may also include a near field communication (NFC) transceiver for pairing the device with a second device. A processor in the device determines that the device is paired with the second device via the NFC transceiver; determines at least one of the orientation and the position of the device; and executes the set of instructions associated with at least one of the determined orientation and position of the device.
