Eyeglasses With Flexible Optical Central Part
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spectacles designs that aim to reduce side light entry and provide protection are either bulky, expensive, or impractical for wearers who need to correct ametropia and use yellow filter or 3D glasses simultaneously.
Innovation Solution
The design features spectacles with temples articulated via a pivot connection to a flexible optical central part, which becomes increasingly curved as the temples are pivoted out, allowing the peripheral line to contact the face and reduce side light entry, while being foldable for storage and easy to manufacture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the optical central part is made rigid and extends to the facial surface to reduce side light entry, then light protection is improved, but the glasses become bulky and expensive to produce
Solution Approach 1:
The patent uses a flexible optical central part made of elastomeric material that can be curved to contact the facial surface, replacing rigid protective structures with a flexible membrane that achieves the same light-blocking function while being thinner and less bulky
Solution Approach 2:
The patent changes the physical state of the optical central part from rigid to flexible by selecting elastomeric materials with specific durometer values (Shore A 40-80), enabling the material to be deformed into a curved configuration that contacts the face and blocks side light without requiring bulky rigid structures
2Device complexity
If the optical central part is made flexible to reduce bulk, then device complexity is reduced, but the ability to maintain contact with the face for light protection is worsened
Solution Approach 1:
The patent makes the optical central part dynamically adaptable by using flexible elastomeric material that can be deformed during use to contact the facial surface, allowing the structure to transition from a non-contacting to a contacting state to block side light as needed
3Reliability
If the temples are made non-foldable to maintain structural integrity, then reliability is improved, but ease of storage and portability is worsened
Solution Approach 1:
The patent introduces a foldable hinge connection between the temples and the optical central part, allowing the temples to be rotated and folded against the front surface of the optical central part for compact storage, while maintaining structural integrity when unfolded for use
Solution Approach 2:
The patent allows the temples to be folded and nested against the front surface of the optical central part, creating a compact stored configuration where the temples are positioned along the optical central part rather than extending outward
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 design effectively reduces side light entry, is practical for use, and cost-effective, allowing for the wear of corrective glasses underneath, with a flexible and foldable structure that maintains optical integrity and comfort.
Implementation Method 1
the optical center part is made of a flexible material... the central optical part, which is made of a flexible material, assumes a state that is dependent on the pivoting angle of the brackets and becomes increasingly curved as the pivoting angle increases

AI summary
The invention relates to eyeglasses (1) with two frames (3), each of which is hinged to an optical central part (2) that covers the field of view in the usage position via a hinge connection (4) and which can be pivoted from a mounting state in which the frames (3) rest against the optical central part (2) into a usage state in which the frames (3) are folded away from the central part (2), wherein the optical central part (2) is made of a flexurally elastic material. According to the invention, each of the two frames (3) is hinged to the central part (2) via a curved hinge connection (4) axis or via at least two straight hinge connection (4) axes which are arranged transversely to each other. In this manner, protective eyeglasses or 3D glasses are provided in which laterally entering light which does not cross the optical central part (2) but rather reaches the eye of the wearer is eliminated as much as possible in the usage position. The eyeglasses (1) can be handled in a convenient manner and are inexpensive to produce.
