Solution Overview

Problem

Existing earphones fail to provide a secure and comfortable fit during active use due to lack of anchoring, discomfort from ill-fitting designs, and instability during energetic movements, especially with magnetic attachment systems that do not accommodate a wide range of ear shapes and require adjustment.

Innovation Solution

A wearable device with a magnetic attachment system comprising a hook-shaped body section and an earpiece, utilizing strong neodymium magnets for secure retention, adjustable positioning, and a flexible design to fit various ear shapes, ensuring the device's center of mass is aligned with the ear for stability and comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If magnetic attachment mechanisms are used in earphones, then the device can be easily attached and detached, but they do not provide sufficient anchoring to retain the earphone during energetic movements

Engineering Contradiction:
Improveease of attachmentVSAvoidretention during movement
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The device is divided into two separate components: a body section that hooks around the ear and an earpiece that inserts into the ear canal. This segmentation allows each part to perform its specific function optimally - the body section provides anchoring while the earpiece provides audio output, resolving the contradiction between easy attachment and secure retention.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent combines magnetic attachment with a hook-shaped body section design. The magnets are integrated into both the body section and earpiece, creating a unified attachment system that leverages both magnetic force for easy attachment/detachment and the hook structure for mechanical anchoring during movement.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If fixed or flexible loops are used to hook around the ear, then the earphone is secured, but the ear must conform to a specific shape and can be uncomfortable for some users

Engineering Contradiction:
Improvesecuring the earphoneVSAvoidfit to ear shapes
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The body section is designed with flexibility to adapt to different ear shapes and sizes. The flexible material allows the hook to conform to the unique contours of each user's ear, providing secure retention without requiring the ear to fit a specific mold, thus resolving the contradiction between securing the device and adapting to various ear shapes.

Inventive Principle:
Principle #15Dynamics

3Reliability

If the earpiece is deeply inserted to achieve secure fit, then anchoring is improved, but it may cause damage to the ear

Engineering Contradiction:
ImproveanchoringVSAvoidear damage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

By separating the anchoring function (body section with hook) from the audio delivery function (earpiece), the patent eliminates the need for deep insertion. The body section provides the necessary mechanical anchoring outside the ear canal, allowing the earpiece to remain shallow and non-invasive, thus resolving the contradiction between anchoring and preventing ear damage.

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If custom moulded solutions are used, then a personalized fit is achieved, but they are expensive and unsuitable as a mass produced item

Engineering Contradiction:
Improvepersonalized fitVSAvoidmass production
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent designs a universal body section with flexible material and adjustable magnetic strength that can accommodate a wide range of ear shapes and sizes without requiring custom molding for each user. This universal design maintains personalized fit capabilities while being suitable for mass production, resolving the contradiction between adaptability and ease of manufacture.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A wearable device for attachment to the ear of a user that includes a magnetic attachment system. The wearable device includes an earpiece including a speaker and a body section including a hook for attachment about the ear. First and second magnetic elements are provided on the earpiece and body. The earpiece is movable relative to the body section and the earpiece and body section are configured so that when the body section is hooked about the ear the magnetic elements are magnetically attracted to each other through the ear to retain the device in place.
