QR Code Wall-Mounted Audio Zone Controller Remote Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall-mounted audio system controllers are limited in access and control capabilities, being fixed to a wall and only allowing basic audio volume control within a specific zone, without the ability to provide expanded remote control functionality.
Innovation Solution
A QR code-based system where each wall-mounted audio system zone controller displays a unique QR code, allowing users to access a website for expanded remote control functionality by scanning the code with a smartphone, enabling control of audio parameters beyond basic volume adjustments from any network-connected location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If wall-mounted audio system controllers are fixed to walls for stable installation, then installation stability is improved, but user accessibility and remote control capability are restricted
Solution Approach 1:
The patent introduces a QR code as an intermediary element on the wall-mounted controller that mediates between the fixed installation and remote access needs. The QR code contains encoded URL information that, when scanned by a smartphone, provides a bridge to the audio control system, allowing users to access control functions remotely without needing physical proximity to the wall-mounted device.
Solution Approach 2:
The patent transitions the control interface from a two-dimensional physical wall-mounted display to a multi-dimensional remote access system. By encoding control system information in a QR code and accessing it through a smartphone's web browser, the system adds spatial dimensions (remote locations) and device dimensions (smartphone, tablet, computer) to the control interface, enabling access from any location with network connectivity.
2Device complexity
If wall-mounted controllers provide basic local control functions, then device simplicity is maintained, but control capability and functionality are limited
Solution Approach 1:
The patent makes the wall-mounted controller universal by integrating multiple functions: it serves as both a local physical control interface and a remote access gateway. The QR code mechanism enables the simple wall-mounted device to provide access to advanced control capabilities that would otherwise require a complex dedicated remote control system, allowing the same device to adapt to different user needs and locations.
Solution Approach 2:
The patent creates a virtual copy of the control interface through the QR code and smartphone web browser. Instead of adding physical controls to the wall-mounted device, the system generates a digital replica of the control functionality that can be accessed remotely, providing expanded control capabilities without increasing the physical complexity of the wall-mounted unit.
3Ease of operation
If control functions are integrated into the wall-mounted controller, then local control is improved, but remote access capability is lost
Solution Approach 1:
The patent merges local and remote control capabilities into a unified system. The wall-mounted controller and remote smartphone access are combined through the QR code gateway, creating an integrated control system where both local physical interaction and remote digital access work together. The QR code acts as a connector that combines the simplicity of wall-mounted installation with the flexibility of remote smartphone control.
Data Source
AI summary
A system of wall-mounted audio system zone controllers, each having a digital display of a QR code that is unique to that particular wall-mounted controller. By scanning the QR code with a smart phone, or the like, where that smartphone is connected to the same network as the audio processing assembly that is communicatively connected to the particular wall-mounted zone controller, a user gains access to a website that provides expanded and remote audio control functionality over and above that provided by the wall-mounted zone controller itself. A wireless network router is in communication with the audio processing assembly and with the smart phones used to scan QR codes.
