Proximity-Based Mobile Devices as Wireless Peripherals With Lock-State Roles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to efficiently operate multiple mobile devices in close proximity without the hassle of physically switching between them, especially for users carrying one device for business and another for personal use, while ensuring security and flexibility in interactions.
Innovation Solution
Mobile devices can dynamically repurpose as wireless peripheral input/output devices when in close proximity, with one device functioning as a host and the other as an accessory, using customizable proximity radii and wireless communication techniques like NFC, Bluetooth, and Wi-Fi to enable seamless interaction and data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple mobile devices are used in close proximity, then device functionality and versatility are improved, but device complexity and operational difficulty increase
Solution Approach 1:
The system automatically detects proximity between devices and establishes wireless peripheral connections without requiring manual pairing or configuration. The devices self-identify host and accessory roles based on operational states, eliminating the need for users to navigate complex pairing procedures while maintaining multiple device functionality
Solution Approach 2:
The system dynamically assigns host and accessory roles based on real-time operational states of devices. When a device is locked or inactive, it automatically becomes an accessory; when unlocked and active, it becomes a host. This dynamic role assignment simplifies operation by eliminating manual configuration while adapting to changing usage scenarios
2Ease of operation
If wireless peripheral connection is established between mobile devices, then ease of operation is improved, but security risks increase
Solution Approach 1:
The system dynamically evaluates security conditions by monitoring device lock states and operational modes before establishing wireless peripheral connections. Connections are only permitted when security criteria are met (e.g., host device is unlocked, accessory device is locked), providing automated security validation that simplifies user operation while maintaining protection
Solution Approach 2:
The system introduces an intermediary security validation layer that mediates connection requests between devices. This intermediary checks security conditions (lock states, operational modes) and either permits or blocks connections accordingly, providing automated security enforcement that maintains ease of operation while preventing unauthorized access
3Productivity
If proximity-based automatic connection is implemented, then productivity is improved, but loss of information control increases
Solution Approach 1:
The system dynamically controls data flow and interaction capabilities based on device operational states and user preferences. When devices are in proximity, the system automatically enables certain interactions (e.g., using one phone to control another) while maintaining user-configurable boundaries on what data and functions are accessible, providing automated efficiency gains with retained information control
Solution Approach 2:
The system implements granular control over different types of data and functions exchanged between devices. Users can selectively permit or restrict specific data categories (e.g., contacts, messages, media) and functions (e.g., camera access, microphone access) on a per-device basis, allowing automated proximity-based operation while maintaining precise local control over information flow

AI summary
A mobile phone having an application or system module operable to attach the mobile phone to a computing device as a wireless accessory to the computing device over a wireless connection between the mobile phone and the computing device, based at least in part on that the mobile phone is located within a predetermined proximity radius from the computing device, and a display device of the computing device is inactive.
