Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Pince-Nez eyeglasses fail to provide a universal fit for noses of varying sizes and shapes, leading to discomfort and instability, and they are not easily storable due to the absence of temple pieces.
Innovation Solution
The design incorporates a bendable bridge with a spring force that allows for adjustable nose pads and a compact storage case, enabling the eyeglasses to fold into a small space while maintaining stability and comfort across different nose widths, using materials like Nitinol wire and polycarbonate lenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If Pince-Nez eyeglasses apply significant clamping force on the nose to stabilize the lenses, then the stability is improved, but user comfort deteriorates due to discomfort and breathing restriction
Solution Approach 1:
The patent changes the physical parameters of the bridge by introducing a spring mechanism that provides controlled elastic force. This transforms the rigid clamping structure into a flexible one that adapts to different nose shapes and sizes, maintaining stability while reducing excessive clamping force and improving comfort.
Solution Approach 2:
The bridge is designed with spring elements that allow dynamic adjustment of the clamping force. The spring mechanism enables the bridge to flex and adapt to various nose geometries, providing stable support without applying excessive or uncomfortable pressure on the user's nose.
2Adaptability or versatility
If Pince-Nez eyeglasses are designed to accommodate noses of varying sizes and shapes, then the adaptability is improved, but the stability deteriorates due to difficulty in maintaining secure fit
Solution Approach 1:
The spring-loaded bridge design creates a universal fitting mechanism that can accommodate various nose sizes and shapes. The elastic properties of the spring allow the bridge to adjust to different anatomical variations while maintaining consistent stabilizing force, achieving both universality and stability.
Solution Approach 2:
The patent utilizes the variable elastic parameters of the spring mechanism to adapt to different nose geometries. By changing the effective spring constant and deflection through design, the system maintains optimal clamping force across a range of nose sizes and shapes, ensuring both adaptability and stability.
3Volume of moving object
If temple pieces are folded toward the lenses to reduce storage size, then the volume is reduced, but the temple pieces still take up storage space and limit accessibility
Solution Approach 1:
The patent removes the temple pieces entirely from the eyeglass structure, extracting the problematic component that occupied storage space and limited accessibility. This extraction enables the eyeglasses to be stored in a much more compact form without the bulk of folded temple pieces.
Solution Approach 2:
Instead of folding the temple pieces to reduce size, the patent inverts the approach by eliminating them completely and relying on the spring-loaded bridge alone for stability. This inversion of the traditional design paradigm achieves compact storage while maintaining wearability.
4Strength
If the bridge is made rigid to maintain structural strength, then the strength is improved, but the adaptability to different nose shapes deteriorates
Solution Approach 1:
The patent changes the mechanical parameters of the bridge by incorporating spring elements that provide controlled flexibility. This allows the bridge to maintain sufficient structural strength while gaining the ability to adapt to different nose shapes through elastic deformation within designed limits.
Solution Approach 2:
The bridge may utilize composite construction combining rigid and flexible materials, or integrate spring mechanisms within the bridge structure. This composite approach maintains overall structural integrity and strength while introducing localized flexibility for adaptation to various nose geometries.
