Head-Mounted Display Position Adjustment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted display devices, such as those used in firefighting, require users to remove the facepiece or goggles to adjust the display position, limiting usability and versatility.
Innovation Solution
A head-mounted display device with a cover section and a position adjusting mechanism that allows for external adjustment of the display section's position without removing the cover, featuring a light transmitting section for visibility of the outside world and a turnable display section to optimize image recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display position is adjusted by a screw mechanism while wearing the device, then the display position can be adjusted, but the user cannot adjust it without taking off the facepiece or goggles
Solution Approach 1:
A position adjusting mechanism with an operation section is introduced as an intermediary between the user and the display section. The operation section extends through the cover section to the opposite side, allowing the user to adjust the display position from outside the cover section without removing it. This mediator enables indirect access to the adjustment mechanism while maintaining the protective and functional integrity of the cover section.
2Adaptability or versatility
If the display section is fixed in position, then the structure is simple, but the user cannot adjust the display position to optimize image recognition
Solution Approach 1:
The display section is transformed from a fixed structure to a dynamically adjustable one. The position adjusting mechanism includes a coupling section that couples to the display section and an operation section that enables the user to change the display section's position relative to the cover section. This dynamic capability allows the display position to be optimized for different user needs while maintaining a relatively simple overall structure.
3Illumination intensity
If the light guide section is made transparent to see the outside world, then visibility of the outside world is improved, but the light guide section may be stained by direct contact
Solution Approach 1:
The operation section acts as an intermediary that allows adjustment of the display section without requiring direct contact with the light guide section. By coupling to the display section through the coupling section and extending through the cover section, the operation section enables users to adjust positions from outside the cover section, preventing fingerprints and stains on the light guide section while maintaining its transparency for outside world visibility.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables adjustable display positioning while worn, improving usability and versatility by allowing simultaneous recognition of images and the outside world, preventing stains, and maintaining clear visibility.
Implementation Method 1
a light guide section having light transmissivity and configured to guide the image emitted from the image emitting section to the eyes of the user
Implementation Method 2
The cover section includes a light transmitting section opposed to the display section... the user wearing the head-mounted display device can visually recognize an outside world of the cover section via the light transmitting section

AI summary
[Solution] A head-mounted display device includes a display section disposed in front of eyes of a user and configured to display an image, a cover section configured to cover the display section when viewed from a position right opposed to the user and wearable on the user, and a position adjusting mechanism capable of adjusting a position of the display section on an opposite side of the display section side across the cover section. The cover section includes a light transmitting section opposed to the display section.
