Solution Overview

Problem

Existing electronic wearable devices face challenges in aesthetics and limited battery life, and there is a need for improved methods to securely and aesthetically attach them to eyewear without frequent charging, especially as they become smaller.

Innovation Solution

The eyewear system incorporates a temple guide made of ferromagnetic material with a magnetic track that allows for slidable attachment and retention of electronic devices, using a combination of ferromagnetic inserts and guides to securely hold devices while allowing for easy attachment and detachment, and a safety catch to prevent accidental disengagement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If the electronic wearable device is made smaller to improve aesthetics and wearability, then the device becomes less noticeable and more comfortable, but the device becomes more difficult to securely attach to eyewear

Engineering Contradiction:
Improvesize of electronic wearable deviceVSAvoidattachment security
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The attachment system is divided into separate magnetic components: a magnetic track embedded in the eyewear temple and a corresponding magnetic element in the wearable device. This segmentation allows the device to remain small while maintaining secure attachment through distributed magnetic forces along the track.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The attachment mechanism transitions from mechanical interlocking to magnetic field interaction, adding a dimensional aspect to the attachment. The magnetic field extends through space, enabling secure attachment of small devices without physical contact points that would compromise aesthetics or device size.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Ease of operation

If magnetic adhesion is used to facilitate attachment of decorative elements, then attachment becomes easier and more flexible, but the attachment strength may be insufficient for secure device retention

Engineering Contradiction:
Improveattachment easeVSAvoidattachment strength
Core Design Contradiction:
Ease of operationVSStrength

Solution Approach 1:

The magnetic track combines multiple functions into a single structure: it provides magnetic attraction for easy attachment, mechanical guidance through track walls, and position indication through visual features. This merging resolves the contradiction by integrating ease of operation with secure retention in one system.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The temple incorporates a ferromagnetic insert within the temple structure, creating a composite that provides both structural integrity and magnetic properties. This allows the magnetic attachment to be sufficiently strong while maintaining the ease of magnetic engagement.

Inventive Principle:
Principle #40Composite materials

3Stability of the object's composition

If the magnetic track walls are formed by a second material disposed around the ferromagnetic insert, then the track structure is enhanced and device positioning is improved, but the manufacturing complexity increases

Engineering Contradiction:
Improvetrack structure stabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The second material serving as track walls performs multiple functions: it provides structural containment for the ferromagnetic insert, defines the magnetic field geometry, and offers visual indication of the track position. This multi-functionality justifies the additional manufacturing step by consolidating several requirements into one component.

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