Eyeglass Nose Pad with Embedded Identification Insert
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current nose pads for eyeglasses face challenges in providing adequate mobility and ease of mounting/removal, while also allowing for visible inserts like logos or wordings, and ensuring product authenticity without compromising the appearance or increasing production costs.
Innovation Solution
A nose pad made of partially transparent, elastically deformable material with a connecting portion and an embedded insert that can be read by an external device, using a deformable material for the connecting portion and a rigid insert for the logo/wording, allowing for easy assembly and hidden identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid material is used for the nose pad, then the structural stability is improved, but the ease of mounting and removal deteriorates
Solution Approach 1:
The nose pad is divided into two distinct parts: a rigid insert (50) that provides structural stability and a deformable connecting portion (40) that enables easy mounting and removal. The rigid insert contains the through-hole and logo, while the deformable connecting portion facilitates interaction with the pin, allowing the nose pad to be easily attached and detached without compromising the stability of the rigid component.
Solution Approach 2:
The nose pad combines two materials with complementary properties: a rigid material for the insert (50) to ensure structural stability and a deformable material for the connecting portion (40) to enable ease of mounting and removal. This composite structure allows each material to perform its optimal function, resolving the contradiction between stability and ease of operation.
2Ease of operation
If a deformable material is used for the connecting portion, then the ease of mounting and removal is improved, but the reliability of mobility over time deteriorates
Solution Approach 1:
The nose pad is divided into a rigid insert (50) that maintains structural integrity and a deformable connecting portion (40) that provides ease of mounting and removal. The rigid insert ensures that the through-hole geometry remains stable over time, while the deformable connecting portion allows for easy attachment without compromising the long-term reliability of the rigid component.
3Loss of information
If an insert with logo is embedded in the nose pad, then the brand identification is improved, but the ease of mounting and removal deteriorates
Solution Approach 1:
The nose pad is segmented into a rigid insert (50) containing the logo for brand identification and a deformable connecting portion (40) that enables easy mounting and removal. The logo is embedded in the rigid insert, which maintains its position and visibility, while the deformable connecting portion allows for easy attachment without affecting the logo's integrity or visibility.
Solution Approach 2:
The nose pad combines a rigid material for the insert (50) to ensure brand identification and a deformable material for the connecting portion (40) to enable ease of mounting and removal. This composite structure allows the logo to remain visible and stable while the connecting portion provides operational ease.
4Reliability
If identification chips are placed inside the frame, then the product authentication is improved, but the manufacturing complexity and appearance compromise deteriorate
Solution Approach 1:
The identification chip is extracted from the frame and relocated to the nose pad insert (50). This extraction removes the chip from the complex frame structure, simplifying frame manufacturing, and places it in a simpler, more accessible location on the nose pad where it can be easily integrated without increasing overall manufacturing complexity.
Solution Approach 2:
The identification chip is embedded within the nose pad insert (50), creating a hidden copy of the authentication mechanism that is accessible for verification but not visible from the outside. This copying approach allows authentication functionality to be maintained while the chip remains concealed, avoiding appearance compromise.
