Head-Mounted Display Fixing Stand for Reducing Neck Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted type eye testing devices are heavier than gaming machine displays, causing a significant physical burden on users, especially elderly persons and children, when mounted on the head.
Innovation Solution
A head-mounted display unit with a detachable and adjustable fixing stand that supports the display in a forward-tilting orientation, allowing for both mobile and fixed use, and includes a chin rest for user comfort, reducing the physical burden by distributing the weight of the display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the head-mounted display is made heavier to include more functional components for eye testing, then the device functionality is improved, but the physical burden on the user's neck and shoulders increases
Solution Approach 1:
The system is divided into two segments: a lightweight head-mounted display unit that can be worn by the user, and a separate fixing stand that supports the display when not in use. This segmentation allows the functional components to remain in the head-mounted unit while the weight burden is reduced during actual usage, as the stand bears the weight when the device is docked.
Solution Approach 2:
The fixing stand acts as an intermediary between the head-mounted display and the supporting surface. It provides structural support and weight bearing capability, allowing the display to be securely positioned without requiring the user to constantly support its full weight during usage.
2Stability of the object's composition
If the head-mounted display is made more stable and fixed in position, then the display stability is improved, but the portability and ease of adjustment are reduced
Solution Approach 1:
The fixing stand incorporates adjustable components including a height-adjustable support rod and an angle-adjustable mounting bracket. These dynamic elements allow the stand to be configured in different positions and orientations, providing both stability when fixed and adaptability when adjusted, thus resolving the contradiction between stability and portability.
Solution Approach 2:
The stand allows changing of geometric parameters such as the height of the support rod and the angle of the mounting bracket. By adjusting these parameters, the system can transition between a stable fixed state for extended use and a more portable, reconfigurable state for different usage scenarios.
3Weight of moving object
If the head-mounted display is designed to be lightweight for comfort, then the physical burden is reduced, but the device may lack sufficient functional components for comprehensive eye testing
Solution Approach 1:
The system segments functionality between the head-mounted display (which remains lightweight) and the external fixing stand (which can house additional functional components). This allows comprehensive eye testing capabilities to be distributed across both units while keeping the wearable portion lightweight and comfortable.
Solution Approach 2:
The fixing stand serves multiple functions: it provides structural support, houses additional eye testing equipment, stores accessories, and offers a stable platform for the display. This multi-functionality compensates for the limited capacity of the lightweight head-mounted unit, ensuring comprehensive functionality without adding weight to the wearable device.

AI summary
Physical burden when a head-mounted display is mounted to the head of a user for use is reduced. A head-mounted display unit includes a head-mounted display, and a fixing stand configured so as to enable the attachment and detachment of the head-mounted display, and to enable the head-mounted display to be mounted in a fixed state. The fixing stand includes a base member, a support column projecting perpendicularly upwards from the base member, a pedestal mount attached to an upper end portion of the support column, a retaining member attached to the pedestal mount, a clamping implement, and a chin rest. The fixing stand is configured such that the head-mounted display is detachably mounted to the retaining member using the clamping implement.
