Master-Slave Device Extension via NFC Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communications devices limit operators to their inherent features and resources, restricting tasks that require additional capabilities such as simultaneous internet browsing and email reading, as operators cannot easily expand the device's features or display size.
Innovation Solution
A master communications device can seamlessly engage a slave device to provide additional features and resources, such as a larger display, through automated discovery and advertisement modes using sensors like NFC, allowing the combination of devices to function as a single interactive system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional single device is used, then the device structure remains simple and easy to operate, but the device cannot provide additional features and resources when needed
Solution Approach 1:
The patent combines a conventional device with an extended device to form a unified system. The extended device provides additional features and resources (such as larger display, camera, or audio capabilities) while the devices communicate through a communication interface. This merging allows the system to adapt to different operational requirements without permanently increasing the complexity of the base device.
Solution Approach 2:
The system dynamically adjusts its configuration by enabling or disabling the extended device based on operational needs. The controller can activate the extended device when additional features are required and deactivate it when not needed, making the system adaptable without permanent structural complexity.
2Area of moving object
If the display size is increased to provide more features, then more information can be displayed, but the device becomes larger and less portable
Solution Approach 1:
The display functionality is segmented between the conventional device and the extended device. The extended device can provide an additional display screen or larger display area, while the conventional device maintains its compact size. This segmentation allows the user to access larger display capabilities when needed without permanently increasing the size of the portable device.
3Adaptability or versatility
If multiple devices are integrated to provide additional features, then the system becomes more versatile, but the operation becomes more complex
Solution Approach 1:
The extended device is designed with multi-functionality to handle various tasks. It can serve as an additional display, provide camera functions, offer audio capabilities, or act as a remote control, depending on the operational context. This universal design reduces the need for multiple specialized devices and simplifies operation through a single versatile extension.
Solution Approach 2:
The system includes automatic detection and configuration capabilities. When the extended device is connected, the controller automatically detects it and configures the communication interface and data transmission protocols without requiring manual setup from the user, maintaining ease of operation despite the added functionality.
4Adaptability or versatility
If a larger display is built into the device, then more features can be accessed simultaneously, but the device consumes more energy
Solution Approach 1:
The extended device, which may include a larger display, is activated only when additional features are needed. The controller can dynamically power on or off the extended device based on the current task requirements, reducing energy consumption when the extended features are not in use while maintaining adaptability when they are needed.

AI summary
A master communications device/slave device configuration is disclosed where a master communications device discovers a slave device when the master communications device does not have the necessary features and resources to perform a service requested by an operator. The master communications device utilizes the slave device to provide additional features and resources to the master communications device in performing the service requested by the operator. The master communications device and the slave device interact as a single device provided by the master communications device/slave device configuration. The slave device serves as an extension to the master communications device providing a larger interface to the operator.
