Eyewear Bridge Pad Stabilization for Anti-Slip Fit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard eyewear attachments fail to securely affix glasses when the user tilts their head upward, leading to movement and discomfort, especially in medical or dental procedures where fogging of lenses can occur due to poor fit and weight distribution.
Innovation Solution
The introduction of a stabilization nosepiece or bridge pad that extends towards the orbital bone, providing cushioning and support, coupled with a nose pad configuration that distributes the weight of the eyewear evenly, preventing movement and fogging by maintaining space between lenses and eyelashes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard eyewear attachments are used, then the structure is simple, but the eyewear slides toward the forehead when the user tilts their head upward
Solution Approach 1:
The attachment is divided into multiple functional components: a bridge pad portion that contacts the brow/orbital bone area, and nose pad portions that contact the nose. This segmentation allows each component to perform its specific function - the bridge pad prevents upward sliding by engaging the brow area, while the nose pads provide additional support and weight distribution.
Solution Approach 2:
The bridge pad extends in a new spatial dimension - forward toward the brow/orbital bone area - rather than only downward onto the nose. This dimensional extension creates a new contact point that prevents upward movement of the eyewear when the head is tilted back.
2Object-affected harmful factors
If the eyewear is positioned close to the eyes for protection, then eye protection is improved, but the eyewear causes discomfort and fogging when the user tilts their head
Solution Approach 1:
The bridge pad is designed with cushioning material that contacts the brow/orbital bone area before the eyewear can slide upward. This pre-positioned cushioning element absorbs and distributes the forces that occur when the user tilts their head back, preventing discomfort and maintaining proper eyewear position without compromising eye protection.
3Ease of operation
If the eyewear weight is concentrated on the nose, then the attachment structure is simple, but the nose pads cause discomfort and fogging
Solution Approach 1:
The weight distribution system is segmented into multiple contact points: the bridge pad contacting the brow/orbital bone area and nose pads contacting the nose. This segmentation distributes the eyewear weight across multiple facial structures rather than concentrating it all on the nose, reducing pressure and discomfort while maintaining a relatively simple overall structure.
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
This solution ensures the eyewear remains securely positioned, reducing discomfort and fogging, even in inclined positions, by distributing weight and allowing airflow, thus enhancing user comfort and vision clarity.
Implementation Method 1
bridge pad 18 engages a least a portion of orbital bone 17 to prevent eyewear 12 from sliding away from the worn position
Implementation Method 2
Bridge pad 18 can be configured to flex and/or absorb these forces. In accordance with example implementations, one or both of the curved bias of bridge pad 18 and/or the hollow configuration, as well as the coupling of bridge pad 18 to eyewear 14 can allow for this cushioning.

AI summary
Eyewear attachments are provided that can include a bridge pad having a base extending between terminal ends and defining a perimeter, and each terminal end having a tower extending normally from the base and forming at least a portion of a top opposing the base of the bridge pad. Eyewear assemblies are provided that can include a frame having a bridge extending between two lense housings, each of the lense housings have an upper portion opposing a lower portion of the housed lense, and a bridge pad coupled to the frame. Methods of affixing eyewear in useful configuration are provided that can include, providing eyewear having a bridge pad, the bridge pad extending away from the eyewear and toward the face when the eyewear is in the worn position, and aligning at least a portion of the bridge pad below an upper portion of the orbital bone of the face.
