Flexible Nose Support for Eyeglasses via Integral SBC Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional eyeglasses with rigid nose pads are uncomfortable, prone to displacement, and lack adjustability, leading to instability and potential loss, while integrally formed rigid nose pieces offer little flexibility for a secure fit.
Innovation Solution
A flexible nose support system with an integrally formed mounting pad and flexible support arms, made from soft plastic materials like SBC, which can self-adjust to fit various nose shapes, providing enhanced comfort and stability without the need for screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid nose pads are used with screw fastening, then structural stability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the nose pad and support arm into a single integrally formed flexible nose support component. This eliminates the need for separate screw fastening mechanisms and threaded holes, reducing structural complexity while maintaining stability through the integral construction that prevents detachment.
Solution Approach 2:
The patent removes the screw fastening system and threaded hole requirements from the design. By extracting this complex fastening mechanism and replacing it with a flexible integral structure, the device complexity and manufacturing cost are reduced while the nose support remains securely attached through its flexible attachment to the frame.
2Manufacturing precision
If rigid nose pads are used, then manufacturing precision is improved, but wearing comfort deteriorates
Solution Approach 1:
The patent changes the material parameter of the nose support from rigid to flexible material. This flexibility allows the nose support to adapt to different nose shapes and sizes, significantly improving wearing comfort while the integral formation with the frame maintains precise positioning without requiring complex adjustment mechanisms.
Solution Approach 2:
The patent introduces dynamic flexibility to the nose support structure. The flexible material allows the nose support to dynamically adjust and conform to the wearer's nose shape, providing comfort while maintaining stable positioning through the flexible attachment to the frame unit.
3Device complexity
If fixed angle nose pads are used, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The patent changes the angle parameter from fixed to variable through the use of flexible material. The flexible nose support can naturally adjust its angle and orientation to match different nose geometries, providing adaptability to various nose shapes while maintaining a simple integral structure without adjustment mechanisms.
4Device complexity
If nose pads are not securely fixed, then device complexity is reduced, but reliability deteriorates
Solution Approach 1:
The patent merges the nose pad and support arm into an integral flexible nose support that is securely attached to the frame. This integral construction eliminates the risk of detachment while avoiding complex fastening systems, as the flexible material creates a secure attachment through its integration with the frame unit.
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 flexible nose support system ensures a secure, comfortable, and stable fit by self-adjusting to the nose shape, reducing the risk of displacement and providing impact protection, while simplifying the manufacturing process and reducing costs by eliminating the need for extensive fastening systems.
Implementation Method 1
The flexible arm includes a fixed end and a free end. The flexible arm extends downward off the fixed end at an angle to form the free end. The mounting pad and the flexible support arms are integrally formed in one piece.
Data Source
AI summary
A flexible nose support and eyeglasses thereof are disclosed. The eyeglasses include an eyeglass body and the flexible nose support. The eyeglass body has a bridge portion, and the flexible nose support has a mounting pad, at least one engaging member, and two flexible support arms, where all are integrally formed in one piece. By mounting the flexible nose support upwardly onto the bridge portion, the flexible nose support is secured to the eyeglasses.
