TWS Earphone Assembly Selective TES Treatment via Link Cable
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional TWS earphone assemblies are limited in their ability to execute a TES treatment function due to their completely separate left and right earphone design, which restricts the applicability and versatility of the TES treatment.
Innovation Solution
A TWS earphone assembly is designed to selectively execute a TES treatment function by incorporating a frequency generator and a TES signal amplifier in one of the earphones, along with electrodes on the outer surface of each earphone, and a link cable that connects the earphones to conduct low-frequency signals for TES treatment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a pair of left and right earphones are completely electrically separated in TWS design, then portability and ease of use are improved, but the ability to execute TES treatment function is restricted
Solution Approach 1:
The system dynamically switches between TWS mode (earphones separated) and TES treatment mode (earphones connected via link cable). The link cable can be connected or disconnected based on user need, allowing the system to adapt its electrical configuration dynamically. This resolves the contradiction by enabling both portable TWS usage and TES treatment functionality at different times.
Solution Approach 2:
The earphone assembly is designed to perform multiple functions: it can operate as a standard TWS earphone for audio playback and can also be configured to execute TES treatment. By incorporating electrodes on the outer surfaces and providing a link cable for electrical connection, the same hardware serves both audio and therapeutic purposes, resolving the versatility restriction.
2Adaptability or versatility
If conventional TES devices include multiple attachment pads and electrical stimulation circuits in a single device, then TES treatment function is provided, but device complexity and cost increase
Solution Approach 1:
The patent reuses the existing TWS earphone hardware (earphones, link cable, electrodes) for TES treatment functionality. Instead of creating a separate dedicated TES device with multiple attachment pads and stimulation circuits, the system leverages the universal earphone components to perform both audio playback and TES treatment, significantly reducing device complexity.
Solution Approach 2:
The TWS earphone system serves itself by using its existing electrodes and link cable for dual purposes: audio transmission and TES treatment. The same hardware infrastructure supports both functions without requiring additional dedicated components, making the system self-sufficient and reducing overall complexity.
