Magnetic Ear Hook Earphone Assembly for Durable Exercise Wear
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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
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.
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
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.
4Ease of operation
If a detachable ear hook is used, then the comfort is improved, but the connection reliability may be compromised
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.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The magnetic connection extends the service life, enhances user comfort, supports exercise reliability, and allows for separate charging, reducing the charging box size and improving user experience.
Implementation Method 1
an earphone portion provided with a second magnetic attraction member, the second magnetic attraction member attracting and cooperating with the first magnetic attraction member such that the earphone portion is connected with the ear hook portion
Implementation Method 2
The connection sensor is a Hall sensor, or a pressure sensor, or a photoelectric sensor
