Voice-Directed Remote Controller Pairing for Device-Specific Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for pairing remote controllers with devices require technical skills and are cumbersome, especially in environments with multiple devices in close proximity, leading to accidental control issues.
Innovation Solution
A voice-controlled pairing method using microphones and sound direction detection to recognize a specific activating phrase, allowing devices to accept commands only within a defined activation angle and store the remote controller identifier for authorized control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional pairing mechanisms are used, then device pairing can be achieved, but the process becomes troublesome and time-consuming for non-technical users
Solution Approach 1:
The system performs automatic device discovery and pairing without requiring user intervention in technical procedures. The RCU automatically detects available devices, initiates pairing protocols, and completes authentication, allowing non-technical users to simply select their device from a list while the system handles all complex pairing operations autonomously
Solution Approach 2:
The system pre-generates pairing codes, establishes device profiles, and prepares authentication credentials before the user needs to pair devices. Device information is pre-configured and stored, so when pairing is initiated, the process completes rapidly without requiring real-time technical setup or user-generated configurations
2Ease of operation
If manual pairing procedures are used, then devices can be paired, but users with limited technical skills find the process difficult
Solution Approach 1:
The system introduces an intermediary pairing interface that mediates between the user and the complex pairing protocols. This interface presents simplified options to users while automatically managing the underlying technical complexity of device discovery, authentication, and connection establishment, shielding users from technical details
Solution Approach 2:
The system creates simplified digital representations or copies of device information and pairing states that are easy for users to interact with. Instead of requiring users to understand complex device identifiers and protocols, the system presents user-friendly device names, icons, and pre-configured pairing options that mirror the actual device functionality without exposing technical complexity
3Adaptability or versatility
If remote controllers can operate multiple devices, then versatility is improved, but accidental control of wrong devices increases
Solution Approach 1:
The system implements device-specific authentication credentials and identification markers that are locally unique to each device-RCU pairing. When an RCU is paired with a device, cryptographic keys, device identifiers, or location-based authentication data are stored locally in the RCU, ensuring that commands are only executed on the paired device even if the RCU is physically near other devices
Solution Approach 2:
The system provides continuous feedback to the user about which device will be controlled by commands from the RCU. Before executing commands, the system displays device identification information, confirms the target device, and provides visual or auditory feedback about the active pairing, allowing users to verify they are controlling the intended device and preventing accidental control
