Head-Mounted Display Support with Deformation Restricting Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted image display devices are bulky due to the need for rigid structures to support image display units, making them difficult to handle and wear, especially when integrated with face masks for applications like rescue operations.
Innovation Solution
A head-mounted image display device design featuring a supporting member with upper and lower extension portions that include deformation restricting portions, allowing for enhanced rigidity without additional structural components, and a light guide member that integrates left- and right-eye light guide portions to guide images to the user's eyes while being protected by a cover member.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid frame is provided in the periphery of the supporting means or the supporting means itself is formed to have high rigidity, then the image display device can be supported stably, but the size of the face mask is increased making it hard to handle
Solution Approach 1:
The supporting means is divided into a face mask attachment portion and a head-mounted supporting portion, allowing the structure to be optimized for each function separately. The face mask attachment portion can be compact while the supporting portion provides necessary stability.
Solution Approach 2:
The belt is configured to extend in the left-and-right direction and pass behind the head, utilizing the third dimension (depth) to provide support without increasing the front-facing size of the face mask. This allows stable support while maintaining a compact profile.
2Volume of moving object
If the supporting means is made flexible to reduce size, then the face mask is easier to handle, but the image display device may bend and displace when force is applied
Solution Approach 1:
The supporting means combines flexible and rigid elements dynamically. The face mask attachment portion can be flexible for comfort and compactness, while the head-mounted supporting portion with belt provides dynamic adjustment and stable support when worn.
Solution Approach 2:
The face mask attachment portion and head-mounted supporting portion are merged into an integrated system where the belt connects the two, combining the benefits of a compact face mask with stable head-mounted support.
3Manufacturing precision
If separate image display devices are fixed to the supporting means for left and right eyes, then each eye receives appropriate image guidance, but the supporting means requires certain rigidity increasing overall size
Solution Approach 1:
The image display system is segmented into separate left and right image display devices, each optimized for its specific function. This allows precise image guidance for each eye while using lightweight individual components rather than a single large rigid structure.
Solution Approach 2:
Each image display device is positioned and configured with local precision for optimal image guidance to its respective eye. The supporting means provides localized support at each eye position rather than requiring uniform rigidity throughout the entire structure.

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 design results in a compact, stable, and reliable head-mounted image display device that can be worn with face masks, enhancing usability and visibility during operations by reducing bulk and maintaining image guidance accuracy.
Implementation Method 1

AI summary
A head-mounted image display device includes a device main body configured to display an image to allow a user to view the image, and a supporting member configured to support the device main body, and to be mounted on the head of the user. The supporting member includes an upper extension portion and a lower extension portion, each extending in a left-and-right direction, and a light guide member configured to guide the image to an eye of the user is interposed between the upper extension portion and the lower extension portion in an up-and-down direction of the user.
