Light-Shielding Member with Inclined Portions for Eyeglass Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted displays with light-shielding members often cause instability in the posture of eyeglasses when worn, leading to potential damage or staining from lens contact and discomfort due to improper fit and light entry.
Innovation Solution
A light-shielding member with a nose accommodation portion and inclined portions that elastically contact the eyeglasses' lens edges, providing a stable fit and reducing external light entry, featuring a design that adjusts to accommodate different head sizes and shapes, including bellows for deformation and cutouts to prevent interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a light-shielding member is added to a head-mounted display, then external light incident to the eyes is reduced, but the posture of eyeglasses becomes unstable
Solution Approach 1:
The light-shielding member is divided into multiple functional portions: a main body portion for light shielding, and a nose accommodation portion with right and left inclined portions that separately contact the eyeglasses. This segmentation allows the light-shielding function to be maintained while the inclined portions provide dedicated support to stabilize eyeglasses, resolving the contradiction between light reduction and eyeglass stability.
2Stability of the object's composition
If the light-shielding member contacts the eyeglasses to stabilize posture, then eyeglass stability improves, but contact pressure causes discomfort and potential damage
Solution Approach 1:
The nose accommodation portion is designed with elastic material that provides cushioning before excessive contact pressure can occur. The elastic right and left inclined portions deform to accommodate the nose and eyeglasses, distributing contact pressure and preventing damage or discomfort while maintaining stable eyeglass posture.
3Adaptability or versatility
If the light-shielding member is designed to accommodate different head sizes and shapes, then adaptability improves, but device complexity increases
Solution Approach 1:
The light-shielding member incorporates elastic and deformable materials that allow dynamic adaptation to different head sizes and shapes. The nose accommodation portion with elastic right and left inclined portions can deform to match various nasal structures, providing adaptability without requiring multiple fixed-size components or complex adjustment mechanisms.
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 stabilizes the posture of eyeglasses, reduces external light incidence, and minimizes uncomfortable contact pressure, preventing lens damage and enhancing user immersion while accommodating various head and nose sizes.
Implementation Method 1
the right portion including a right inclined portion that is inclined downwardly toward the right and that is to elastically come into contact with at least part of an inner side portion of a right lens edge of eyeglasses worn by the user, the left portion including a left inclined portion that is inclined downwardly toward the left and that is to elastically come into contact with at least part of an inner side portion of a left lens edge of the eyeglasses worn by the user
