Solution Overview

Problem

Existing earphones connected to ear hooks via snaps are prone to damage, leading to a short service life and discomfort during prolonged use, especially during strenuous exercise, and require larger charging boxes due to integrated designs.

Innovation Solution

The earphone features a detachable connection using magnetic attraction members on the ear hook and earphone portions, accompanied by a heart rate detection module, allowing for easy assembly/disassembly, improved comfort, and reduced charging box size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If an integrated earphone and ear hook design is used, then the structure is simple, but the ear feels pain after wearing for a long time and the service life is short

Engineering Contradiction:
Improvestructure simplicityVSAvoidservice life
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent divides the integrated earphone design into separate modules: an earphone body and a detachable ear hook. The earphone body contains the main components (speaker, battery, control buttons), while the ear hook is a separate wearable component with a magnetic connection interface. This segmentation allows the earphone body to remain simple in structure while the detachable ear hook can be optimized for comfort and durability independently.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If a snap connection is used between earphone and ear hook, then the assembly is simple, but the snap is easily damaged and service life is short

Engineering Contradiction:
Improveassembly simplicityVSAvoidservice life
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent replaces the traditional mechanical snap connection with a magnetic connection system. The ear hook contains a magnet that magnetically attracts to a ferromagnetic material in the earphone body, creating a secure yet gentle connection. This magnetic mechanism eliminates the stress concentration and mechanical failure points inherent in snap connections, significantly extending service life while maintaining simple assembly.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Stability of the object's composition

If an integrated earphone with ear hook is used, then the connection is stable, but the charging box size increases

Engineering Contradiction:
Improveconnection stabilityVSAvoidcharging box size
Core Design Contradiction:
Stability of the object's compositionVSVolume of stationary object

Solution Approach 1:

The detachable ear hook design allows the earphone body to be charged independently in a smaller charging box. The ear hook, being separate, does not need to be accommodated in the charging box, significantly reducing its volume. The magnetic connection ensures stable attachment during use, while the separate charging capability optimizes the charging box size.

Inventive Principle:
Principle #1Segmentation

4Ease of operation

If a detachable ear hook is used, then the comfort is improved, but the connection reliability may be compromised

Engineering Contradiction:
Improvewearing comfortVSAvoidconnection reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The magnetic connection system provides reliable connection through magnetic attraction force between the magnet in the ear hook and the ferromagnetic material in the earphone body. This magnetic force is sufficient to maintain stable connection during exercise and movement while allowing easy detachment when needed. The connection strength can be optimized by adjusting magnet size and material properties, achieving both reliability and ease of operation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
