Chair system with an untethered chair with speakers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional chair systems with speakers are not designed for untethered movement, as wired connections can be damaged or cause tripping hazards, 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, allowing for wireless audio streaming and reduced power consumption by separating high and low frequency audio components, enabling safe and flexible movement.
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 with wireless audio transmission and battery power, eliminating the wire that causes tripping hazards and potential damage from wheel rolling.
2Reliability
If full-range speakers are mounted on the chair, then the chair can provide complete audio output, but the power consumption increases
Solution Approach 1:
The audio frequency spectrum is segmented into high frequency and low frequency portions. The high frequency portion is transmitted wirelessly to the chair's speakers, while the low frequency portion is played by a subwoofer in the stationary main unit. This segmentation reduces the power consumption of the chair's speakers while maintaining complete audio output quality.
