Solution Overview

Problem

Existing eyeglasses frames with adjustable nose pads often fail to fit the varied dimensions of users' nose bridges, leading to discomfort due to improper fitting.

Innovation Solution

The eyeglasses frame features a nose-pad positioning seat with upper and lower embedded grooves, a U-shaped positioning rod, a coupling body, and a nose pad, utilizing a locking mechanism with locking teeth and a hook groove for precise angle adjustment and secure attachment.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If nose pads are made adjustable to accommodate variations in nose bridge dimensions, then adaptability is improved, but stability and fitting precision deteriorate due to inability to properly fit the sides of nose bridges

Engineering Contradiction:

Improveadaptability to nose bridge variationsVSAvoidfitting precision on nose bridge

Core Design Contradiction:

Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The nose pad assembly is divided into multiple components: a positioning rod with upper and lower inserting parts, a coupling body with hook and curved stopping surface, and a nose pad with slot. This segmentation allows each component to perform a specific function in the adjustment and locking mechanism, enabling precise angular adjustment while maintaining stability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The nose pad assembly incorporates dynamic adjustment capabilities through the coupling body's hook engaging with the curved stopping surface on the positioning rod. This allows the nose pad angle to be adjusted and locked at different positions, providing both adaptability to different nose bridge dimensions and stability once positioned.

Inventive Principle:

Principle #15Dynamics

2Reliability

If a locking mechanism with locking teeth and hook groove is implemented for precise angle adjustment, then stability is improved, but device complexity increases

Engineering Contradiction:

Improvestability of nose pad attachmentVSAvoidcomplexity of adjustment mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The locking mechanism is designed to be self-servicing through the interaction between the hook on the coupling body and the curved stopping surface with locking teeth on the positioning rod. The mechanism automatically locks into position through its geometric design, eliminating the need for additional locking components or complex assembly procedures while maintaining high stability.

Inventive Principle:

Principle #25Self-service
