Flippable Magnifying Glass Prism Headset for Eye Strain Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted magnifying glasses cause eye fatigue and difficulty in viewing due to the magnifying glass being positioned farther away from the user, resulting in a smaller magnified field-of-view, which is inconvenient and leads to dizziness and eye strain during prolonged use.
Innovation Solution
A flippable magnifying-glass main-body with a pivoting mechanism that allows users to switch between a wide-angle view and a magnified view by flipping the magnifying-glass main-body, positioning it closer to the eye, and using multiple prism main-bodies to achieve clear and larger magnified fields-of-view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the magnifying-glass main-body is positioned farther away from the user's eye, then the user can view the lower-side field-of-view in a non-head-down state, but the magnified field-of-view becomes relatively smaller and causes eye fatigue
Solution Approach 1:
The magnifying-glass main-body is made movable through a pivoting mechanism that allows it to rotate between a first position (closer to the eye) and a second position (farther from the eye). This dynamic positioning enables the user to switch between magnified viewing mode and wide-angle viewing mode, resolving the contradiction between viewing convenience and magnified field-of-view size.
2Manufacturing precision
If the magnifying-glass main-body is positioned closer to the user's eye, then the magnified field-of-view becomes larger and clearer, but the user cannot simultaneously access the wide-angle prism field-of-view
Solution Approach 1:
The pivoting mechanism enables dynamic repositioning of the magnifying-glass main-body between two functional positions: closer to the eye for magnified viewing, and farther from the eye for wide-angle viewing through the prism. This resolves the contradiction by making the system adaptable to different viewing requirements.
Solution Approach 2:
The single magnifying-glass main-body serves multiple functions by being positionable in two locations: it acts as a magnifier when close to the eye, and allows wide-angle viewing when positioned farther away. This multi-functionality resolves the contradiction between magnified field-of-view size and field-of-view switching capability.
3Device complexity
If a single prism main-body is used, then the structure is simpler, but the user cannot switch between multiple field-of-views
Solution Approach 1:
The first prism main-body and second prism main-body work together to provide multiple viewing functions: the first prism provides a first wide-angle field-of-view, while the second prism provides a second wide-angle field-of-view. This multi-functional prism configuration enables field-of-view transformation while maintaining reasonable structural complexity.
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
The solution allows for clearer and larger magnified fields-of-view, reducing eye fatigue and improving convenience by enabling users to switch between wide-angle and magnified views without causing dizziness, thus enhancing the usability of head-mounted magnifying glasses.
Implementation Method 1
at least one prism main-body which is adjacent to one side of the user's eye and has a predetermined spacing for changing the user's eyesight direction to create a prism field-of-view
Implementation Method 2
a magnifying-glass main-body set on one side of the facing-object-surface of the prism main-body for magnifying the image size of the target object to generate a magnified field-of-view in the prism field-of-view

AI summary
A field-of-view transformation structure of a head-mounted magnifying-glass comprises: a wearing-piece, a supporting-assembly, a first pivoting-portion, a magnifying-glass main-body, a first prism main-body, and a second prism main-body; wherein the supporting-assembly is set with the wearing-piece, the first pivoting-portion is defined on the supporting-assembly, the magnifying-glass main-body and the first pivoting-portion are pivotally set mutually, a first facing-eye-surface is defined on the first prism main-body corresponding to the magnifying-glass main-body, and a second facing-eye-surface is defined on a offset position of the magnifying-glass main-body; thus, the user can wear the wearing-piece, when wanting using the first prism main-body to watch, the magnifying-glass main-body can be flipped upwards; or, the user can directly view the second facing-eye-surface to simultaneously watch other parts of the patient when watching the magnifying-glass main-body. Besides the magnified field-of-view is bigger than the conventional technology, it also has the advantage of wide-angle field-of-view.
