Solution Overview

Problem

Conventional wireless sound equipment lacks convenience and ease of use, particularly when worn around the neck, as they often require complex operations and are prone to separation from the neck during movement.

Innovation Solution

A wireless sound equipment design featuring a band with elastic and rigid sections, a rotary member with a spiral spring, and a reel for winding audio cables, allowing easy coupling and decoupling of the receiver, and incorporating magnets for secure attachment, along with a controller for controlling mobile terminal functions based on switch states and proximity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the wireless sound equipment uses a band to be worn on the user's neck, then mobility and ease of carrying are improved, but the equipment is prone to separation from the neck during movement

Engineering Contradiction:
Improveease of carryingVSAvoidattachment stability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The band is designed with elastic material that can dynamically adapt to neck movement, stretching and contracting while maintaining continuous contact with the user's neck, preventing separation during physical activity

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The elastic modulus and tensile strength of the band material are specifically optimized to provide sufficient holding force for reliable attachment while maintaining comfort and flexibility for ease of wearing

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If the wireless sound equipment requires complex operations for controlling mobile terminal functions, then control precision is improved, but user convenience is worsened

Engineering Contradiction:
Improvecontrol precisionVSAvoiduser convenience
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The wireless sound equipment automatically detects when the receiver is inserted into the receiver holder and autonomously executes the corresponding mobile terminal function (such as answering a call or playing music), eliminating the need for additional button presses or complex operations by the user

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system is pre-programmed with automatic response logic that triggers specific mobile terminal functions based on the state of the receiver and receiver holder, so that the correct action is taken in advance without requiring user decision-making or multiple steps

Inventive Principle:
Principle #10Preliminary action
