Solution Overview

Problem

Existing sound detector systems, such as hearing aids and headsets, face challenges in efficient communication with portable terminals and require multiple wires, which complicate setup, increase power consumption, and hinder ease of use, especially for individuals with hearing impairments.

Innovation Solution

Implementing a body area network (BAN) that allows sound detectors to communicate directly with portable terminals through the human body, eliminating the need for wires and enabling efficient data transmission and control, thereby simplifying the system and reducing power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wires are used to connect sound detectors to portable terminals, then communication stability is improved, but device complexity and ease of operation deteriorate

Engineering Contradiction:
