Eyeglass Frames with Lowered Bridge and Shorter Temples
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
People with Down syndrome and similar facial characteristics, as well as those of African and Asian descent, face issues with conventional eyeglass frames that do not fit properly due to unique facial features, leading to misalignment of the pupils with the optical center of the lenses, resulting in ineffective vision and discomfort.
Innovation Solution
Designing eyeglass frames with a lower bridge, shorter temples, and wider temple distance to accommodate the specific facial characteristics, along with spring hinges for easier wear and storage, ensuring the pupils align with the optical center of the lenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional eyeglass frames are used for people with Down syndrome, then the frames can be mass-produced and are generally affordable, but the frames do not fit properly due to unique facial features, causing misalignment of pupils with optical center
Solution Approach 1:
The patent applies local quality by customizing specific parts of the eyeglass frame (bridge height, temple length, lens positioning) to match the local facial characteristics of people with Down syndrome, while maintaining standard manufacturing processes for the overall frame structure
Solution Approach 2:
The patent changes critical dimensional parameters of the eyeglass frame including bridge height (lowered to accommodate depressed nasal bridge), temple length (shortened due to low-set ears), and lens optical center positioning to align with the narrower pupillary distance, thereby resolving the misalignment issue
2Ease of operation
If ordinary eyeglass frames are fitted on people with Down syndrome, then the frames can be obtained easily and at lower cost, but the frames sit lower on the face causing the person to look through the upper portion of the glasses
Solution Approach 1:
The patent incorporates preliminary action by pre-positioning the bridge and temples at specific dimensions during manufacturing that are calculated to accommodate the facial characteristics of people with Down syndrome, ensuring proper optical alignment is achieved automatically upon wearing without requiring adjustment
3Reliability
If the bridge is lowered to contact the nose for proper fit, then the frames prevent slipping and improve alignment, but the frame structure becomes more complex
Solution Approach 1:
The patent achieves frame stability through parameter changes by lowering the bridge position and adjusting temple dimensions, which naturally prevents slipping without requiring additional mechanical components or complex adjustment mechanisms

AI summary
Eyeglass frames for people with Down syndrome, for others having facial characteristics similar to those with Down syndrome, and those with a depressed nasal bridge or a low nasal bridge, the eyeglass frames having a bridge lower than the normal higher placed bridge and in general alignment with the optical center of lenses mounted in the lens frames, extensions to widen the temple distance to accommodate the broader temples of people having Down syndrome or facial characteristics similar to those with Down syndrome, lower temples to maintain the general alignment of the location of the optical center with the pupils of the person wearing the eyeglass frames; and shorter temples than temples for normal caucasians to accommodate the ears as located on persons with normal facial features.
