Flexible Spectacles with Rigid Frame and Elastic Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sports glasses often fail to provide optimal protection against environmental influences like wind and sunlight while being comfortable to wear for extended periods, as they either lack flexibility to fit snugly or become uncomfortable due to pressure points from less flexible frames.
Innovation Solution
The design incorporates a frame made of less flexible material with recesses containing elastic elements, allowing for local flexibility and damping, ensuring a secure fit and comfort by absorbing tension and adapting to the head shape, while maintaining stability and protection from wind and sunlight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the frame is made of flexible material, then the glasses can adapt to head shape and provide protection, but the glasses slip due to impacts and vibrations
Solution Approach 1:
The frame is divided into rigid and flexible segments. The upper frame part is made of rigid material to provide stability and prevent slipping, while the lower frame part contains flexible elements to adapt to the head shape and provide comfort. This segmentation allows each part to fulfill its specific function without compromising the other.
Solution Approach 2:
Different parts of the frame have different flexibility characteristics. The upper frame part has low flexibility to ensure stability, while the lower frame part has high flexibility to adapt to head contours. This local differentiation of material properties resolves the contradiction between overall stability and local adaptability.
2Reliability
If the frame is made of less flexible material, then the glasses remain stable on the head, but pressure points occur and comfort decreases
Solution Approach 1:
The frame is segmented into rigid upper parts for stability and flexible lower parts for comfort. The flexible elements in the lower frame part reduce pressure points by adapting to the head shape, while the rigid upper parts maintain overall stability during sports activities.
Solution Approach 2:
The frame exhibits local quality differences with rigid sections for stability and flexible sections for comfort. The flexible lower frame part specifically addresses pressure point issues by conforming to head contours, while rigid sections maintain structural integrity.
3Ease of operation
If the frame is very flexible, then comfort is improved, but the glasses cannot guarantee permanent contact with the head
Solution Approach 1:
The frame is divided into rigid upper parts that ensure stable contact with the head and flexible lower parts that provide comfort. The rigid upper frame prevents slipping while the flexible lower frame adapts to head shape, achieving both reliability and comfort simultaneously.
Solution Approach 2:
Different flexibility characteristics are assigned to different frame parts. The upper frame has low flexibility for stable contact, while the lower frame has high flexibility for comfort. This local differentiation resolves the contradiction between overall stability and local comfort.
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 glasses provide enhanced protection and comfort by maintaining contact with the head, reducing pressure points, and ensuring a tight seal against wind and sunlight, thus improving wearability during sports activities.
Implementation Method 1
An elastic element is provided in the at least one recess... The material from which the frame is made has a lower elasticity than the elastic element... the at least one recess extends from top to bottom on the inner side of the frame
Implementation Method 2
The elastic element has suspension and damping properties and serves to provide areas of the frame with special flexibility

AI summary
The present invention relates to eyeglasses (1) comprising: a frame (2), at least one transparent element (3) attached to the frame (2), and a fastening means (4) adapted for fixing the frame (2) to the wearer's head, the frame (2) having at least one recess (5). Such eyeglasses (1) combine the advantages of both rigid and flexible frames: The frame (2) itself consists of a rigid material along its entire length, which provides stability to the entire frame when worn and ensures constant contact between the eyeglasses (1) and the wearer's head or forehead. Further advantages of a frame (2) made of a rigid material include its low susceptibility to damage or material degradation from sunlight, such as brittleness.
