Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional head-mounted displays attached to eyeglass frames often lack ease of attachment and stability, leading to discomfort and interference with the user's ear and eyeglass frame.

Innovation Solution

A head-mounted display system comprising a first unit with a display element and eyepiece optical part, and a second unit, the temple tip, which includes a temple connecting part and attachment electrodes for detachable engagement, allowing electrical coupling and distributing the weight for improved balance and stability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the head mounted display is attached to the eyeglass frame, then the display can be observed by the user, but the attachment structure interferes with the user's ear and eyeglass frame

Engineering Contradiction:

Improveease of attachmentVSAvoidinterference with ear and eyeglass frame

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The temple tip is divided into a first temple tip and a second temple tip that can be detachably connected. This segmentation allows the display device to be attached to one temple tip while the other remains separate, reducing interference with the user's ear and eyeglass frame while maintaining ease of attachment and detachment.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If the head mounted display is attached to the eyeglass frame, then the display function is provided, but the attachment structure lacks stability

Engineering Contradiction:

Improveease of attachmentVSAvoidstability of attachment

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

A connection structure with connection protrusions and connection grooves acts as an intermediary between the first and second temple tips. This intermediary mechanism provides both ease of attachment through simple engagement and stability through precise fitting of the protrusions into the grooves, ensuring reliable electrical and mechanical connection.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Weight of moving object

If the display device is made compact and lightweight, then comfort is improved, but electrical coupling between components becomes difficult to maintain

Engineering Contradiction:

Improveweight of display deviceVSAvoidelectrical coupling reliability

Core Design Contradiction:

Weight of moving objectVSReliability

Solution Approach 1:

The connection structure merges mechanical connection and electrical coupling functions into a single integrated component. The connection protrusions and grooves simultaneously provide structural support and maintain electrical contacts between the display device and temple tip, ensuring reliable electrical coupling while keeping the device compact and lightweight.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A head mounted display that is attached to an eyeglass frame for use, includes: a first unit and a second unit. The first unit includes a first electrical component including a display element and an eyepiece optical part that allows a user to observe a display image by the display element as a virtual image. The second unit which is a temple tip for display device having a temple connecting part to which a temple of the eyeglass frame is attachable includes a second electrical component and an attachment part in which the first unit is detachably engaged and supported. When the first unit is engaged and supported in the attachment part, the first electrical component and the second electrical component are electrically coupled.
