Bonded Command Dial for Synchronized Multi-Zone Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media playback systems lack a convenient and flexible method for users to control and adjust settings across multiple zone players in a home environment, limiting the dynamic configuration and synchronization of audio playback.
Innovation Solution
A command device that bonds with zone players or zones, allowing users to make adjustments such as volume control, playback operations, and synchronization through a handheld interface with input buttons, processor, and network connectivity, enabling seamless control of multiple zone players.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users control multiple zone players through software applications on mobile devices, then control functionality is achieved, but ease of operation deteriorates due to complex controller interactions
Solution Approach 1:
A command device serves as an intermediary between users and the media playback system. The command device includes a processor that receives input from input buttons and transmits commands to zone players, simplifying user interaction while maintaining system control capabilities.
Solution Approach 2:
The command device autonomously processes user inputs and directly communicates with zone players without requiring users to navigate complex software applications. The device self-manages the control workflow, receiving input via buttons and automatically transmitting appropriate commands to the target zone players.
2Adaptability or versatility
If users dynamically group and ungroup zone players, then adaptability improves, but ease of operation worsens due to physical reconfiguration requirements
Solution Approach 1:
The command device replaces manual physical reconfiguration of zone players with electronic control. Users can dynamically group and ungroup zone players through button inputs on the command device, which transmits wireless commands to modify system configuration without physical intervention.
Solution Approach 2:
The system enables dynamic grouping and ungrouping of zone players through the command device. The configuration can be changed in real-time based on user needs, with the command device facilitating flexible reconfiguration through simple button presses rather than fixed physical connections.
3Productivity
If zone players are controlled individually, then device complexity is reduced, but productivity deteriorates due to lack of synchronized control
Solution Approach 1:
The command device merges control of multiple zone players into a single interface. Users can control multiple zone players simultaneously through the command device, which manages synchronization and coordination internally, improving control efficiency without requiring users to manage each player individually.
Solution Approach 2:
The command device provides universal control capabilities for multiple zone players. A single command device can control different zone players with different functions (playback, volume, grouping), consolidating multiple control functions into one device that improves overall system productivity.
Data Source
AI summary
Embodiments are described herein that provide a dedicated command device that is bonded to a zone player or zone to perform adjustments to the zone player or zone. In an example implementation, a command device receives an instruction to pair with a first playback device that is associated with a group of playback devices that includes the first playback device and at least one additional playback device. The group of playback devices is associated with at least one group variable controlling playback by the playback devices of the group. The command device receives an input to adjust a first group variable of the at least one group variable and transmits, via a wireless communications interface, a command that causes an adjustment of the first group variable for the group of playback devices.
