Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Head-mounted displays with nose pads face issues of positional misalignment and increased load on the nose when the adjustment mechanism shortens the mounting band, which can hinder the user's ability to fully appreciate high-quality video due to the soft material used for nose pads.

Innovation Solution

A head-mounted display design featuring a nose pad assembly with a movable frame and support mechanism that allows motion in front and rear directions, reducing the load on the nose and preventing positional misalignment by using a rigid frame and cushioning nose pads that can be adjusted to fit various nose sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If nose pads are formed of soft material to reduce load on the nose, then the load on the nose is reduced, but positional misalignment of the display apparatus in the left and right directions occurs

Engineering Contradiction:

Improveload on noseVSAvoidpositional alignment

Core Design Contradiction:

Object-affected harmful factorsVSMeasurement precision

Solution Approach 1:

The nose pad assembly is divided into two independent nose pads (right and left) that can move independently, allowing each to adapt to the user's nose shape while maintaining overall positional stability through the rigid frame structure

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The nose pads are designed to be movable in the front-rear direction relative to the apparatus body, allowing them to dynamically adjust to the user's nose position while the rigid frame prevents lateral misalignment, resolving the contradiction between softness for comfort and rigidity for alignment

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the mounting band length is shortened to fit smaller heads, then the fit is improved, but the load on the nose increases

Engineering Contradiction:

Improvefit for different head sizesVSAvoidload on nose

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The nose pad assembly is designed as a movable component that can adjust its position in the front-rear direction, allowing the apparatus to adapt to different head sizes and shapes without increasing nose load, as the dynamic adjustment distributes weight more effectively

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system allows adjustment of the nose pad position and orientation parameters to optimize both fit and load distribution for different users, enabling small-headed users to achieve proper fit without excessive nose pressure

Inventive Principle:

Principle #35Parameter changes

AI summary

A head-mounted display that can suppress positional misalignment of a display apparatus in the left and right directions, and can reduce the load on a user's nose is proposed. A nose pad assembly H has: a movable portion (M2) having a frame (31), and a nose pad (32) attached to the frame (31); and a support mechanism (M1) that is attached to an apparatus body (10), and supports the frame (31). The support mechanism (M1) supports the frame (31) such that a motion of the nose pad (32) in the front and rear directions is allowed.
