Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional commercial and residential automation systems lack contactless remote control capabilities, posing concerns about germ transmission and convenience in accessing and controlling audio-visual systems.
Innovation Solution
The implementation of a contactless remote control method using Quick Response (QR) codes or authorization codes displayed on audio-visual control devices, allowing users to authenticate and control audio-visual systems through their personal devices without physical contact, leveraging cloud connectivity and authentication protocols for secure access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional remote control methods are used requiring physical contact with shared devices, then system control functionality is achieved, but germ transmission risk increases
Solution Approach 1:
The patent replaces the mechanical contact-based control system with a wireless communication system. Users authenticate via QR code scanning or code entry on their personal devices, establishing a wireless connection to the audio-visual system without physical contact with shared control devices. This substitution eliminates germ transmission risks while maintaining full control functionality.
Solution Approach 2:
The patent introduces an intermediary authentication mechanism (QR code or authorization code displayed on the control device) that mediates between the user's personal device and the audio-visual system. This intermediary enables secure connection establishment without direct contact, allowing users to control the system remotely through their own devices.
2Object-affected harmful factors
If contactless remote control is implemented, then germ transmission risk is reduced, but system configuration complexity increases
Solution Approach 1:
The patent uses QR codes or authorization codes as information copies that contain all necessary connection and authentication data. Instead of complex configuration procedures, the system generates these code representations that users can scan or enter, automatically transferring the required system information to their personal devices without manual configuration.
Solution Approach 2:
The system automatically handles the complex authentication and connection establishment processes. When a user scans the QR code or enters the authorization code, the system self-configures the wireless connection, device pairing, and access permissions without requiring users to manually configure technical parameters, thereby reducing perceived complexity.
3Reliability
If authorization codes are displayed on the control device, then secure authentication is enabled, but display time management complexity increases
Solution Approach 1:
The patent implements dynamic display timing for authorization codes based on contextual factors such as detected user presence, scheduled meeting times, or system state. The code display duration and visibility are automatically adjusted according to real-time conditions, providing secure authentication while adapting to user needs without requiring complex manual timing configuration.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor user presence detection, time schedules, and authentication attempts to automatically control authorization code display timing. This feedback-driven approach ensures codes are displayed only when needed and for appropriate durations, maintaining security while simplifying time management through automatic adaptation rather than fixed complex schedules.
