Glasses Display Unit Positioning for Visual Field Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional glasses-type mobile terminals cause discomfort due to the display unit obstructing the visual field, leading to perspective issues, eye fatigue, and size incompatibility with different users.
Innovation Solution
A glasses-type mobile terminal with a moving body that can be controlled to adjust the display unit's position, allowing it to be positioned opposite or distant from the user's eyes, and tilted along predetermined traces to secure the visual field, featuring a joint system with elastic springs and guide bushes for torque transmission and a stopper to limit rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display unit is disposed closely to the user's eye, then the user can obtain visual information output from the display unit, but the display unit covers the user's visual field causing perspective loss
Solution Approach 1:
The display unit is made movable relative to the user's eye through a mechanical joint system. The display can be positioned close to the eye when viewing is needed, and moved away when the visual field should be clear, transforming a static harmful arrangement into a dynamic one that adapts to user needs.
2Object-affected harmful factors
If the display unit is disposed at a position out of the user's visual field, then the user's visual field is secured, but the user should watch a position out of the front causing eye fatigue
Solution Approach 1:
The display unit's position is made dynamically adjustable along a predetermined trace. When viewing is required, the display moves to an optimal position that is out of the direct visual field path but still easily viewable, reducing eye fatigue while maintaining visual field clearance.
3Device complexity
If the display unit is disposed at a fixed position, then the structure is simple, but it is inconvenient for users with different body sizes
Solution Approach 1:
The display unit is equipped with a mechanical joint system that allows it to be adjusted to different positions and angles. This enables users with different head sizes and shapes to position the display optimally for their anatomy, transforming a one-size-fits-all fixed structure into an adaptable dynamic system.
Solution Approach 2:
The connection between the display unit and the headgear is segmented into movable joints rather than a rigid fixed connection. This segmentation allows independent adjustment of the display position while keeping the rest of the structure relatively simple.
4Illumination intensity
If the display unit covers one of the user's eyes, then visual information can be displayed, but the user loses perspective
Solution Approach 1:
The display unit can be dynamically positioned to alternate between covering one eye and clearing the visual field. This dynamic adjustment allows the user to maintain perspective by periodically clearing the visual field while still obtaining visual information when needed.
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 secure visual field maintenance by controlling the display unit's position, reducing eye fatigue and accommodating various user sizes through adjustable positioning and tilting of the display unit.
Implementation Method 1
a plurality of elastic springs respectively disposed between the front frame and the first guide bush and between the front frame and the second guide bush to provide the first and second guide bushes with an elastic force for pressing the joint

AI summary
A glasses-type mobile terminal includes a frame, a fixing body, a moving body and a joint. The frame is wearable on a user's head. The fixing body is coupled to one side of the frame. The moving body has a display unit for providing a user with visual information, and is disposed at the front based on user's eyes. The joint has one end coupled to the fixing body and the other end tiltably connected to the moving body so that the position of the moving body is controlled.
