Untethered Chair with Wireless Audio and Frequency Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chair systems with speakers are not suitable for untethered movement due to wired connections that can be damaged or cause tripping, limiting their flexibility and safety.
Innovation Solution
A chair system comprising a main unit with a wireless transmitter, subwoofer, audio stream receiver, and processor, and an untethered chair with wireless receivers and speakers, where audio streams are processed to separate high and low frequency portions, with the high frequencies wirelessly transmitted to the chair and low frequencies played by a subwoofer, reducing power consumption and eliminating the need for constant wired connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections are used to connect the chair to power source and audio source, then the chair can receive power and audio signals, but the castor wheels may roll over and damage the wires or a person may trip over the wire
Solution Approach 1:
The patent removes the wired connection from the chair system by extracting the power source and audio receiver into separate stationary units. The chair becomes untethered, eliminating wires that could be damaged or cause tripping hazards while maintaining reliable power and audio signal delivery through wireless transmission.
Solution Approach 2:
The patent replaces the mechanical wired connection system with a wireless electromagnetic field-based system. Power and audio signals are transmitted through electromagnetic fields instead of physical wires, allowing the chair to move freely without mechanical constraints or safety hazards.
2Reliability
If full-range speakers are mounted on the untethered chair, then the chair can provide complete audio output, but the power consumption increases
Solution Approach 1:
The patent segments the audio frequency spectrum into different portions, with the untethered chair handling high-frequency audio output through its speakers and the stationary unit handling low-frequency audio output through its subwoofer. This segmentation allows the moving chair to use fewer resources while maintaining complete audio output quality.
Solution Approach 2:
The patent applies partial action by having the untethered chair handle only the high-frequency portion of the audio spectrum rather than the full range. This partial coverage is sufficient for the chair's needs while reducing its power consumption, with the stationary unit complementing it with low-frequency output.
