Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing glasses nose pads fail to maintain an optimal distance between the lenses and the wearer's eyes during activities like cycling, motorcycling, or driving, leading to impaired vision and discomfort due to tilting of the body.

Innovation Solution

A nose pad adjustment structure featuring a frame with lens fixing parts and nose fastening holes, allowing the nose pad's height to be adjusted via fixed shafts and slots, ensuring proper lens positioning and comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the nose pad position is fixed, then the glasses structure is simple, but the distance between lenses and eyes cannot be adjusted when body tilts forward during activities

Engineering Contradiction:

Improveadaptability to different body positionsVSAvoidnose pad adjustment structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The nose pad is designed with adjustable positioning capability, allowing it to move between fixed and adjusted positions. The adjustment mechanism includes movable components that enable the nose pad to adapt to different body positions during activities, transforming a static structure into a dynamic one that responds to changing wear conditions

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The nose pad assembly is divided into separable components including the nose pad itself, the connection arm, and the adjustment mechanism. This segmentation allows independent adjustment of the nose pad position while maintaining the overall structural integrity, enabling adaptability without requiring complete structural redesign

Inventive Principle:

Principle #1Segmentation

2Reliability

If multiple glasses sizes are provided for different activities, then vision clarity is maintained, but the device complexity and cost increase

Engineering Contradiction:

Improvevision clarityVSAvoidmultiple glasses sizes

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The glasses frame is designed with universal adaptability through multiple adjustment positions for the nose pad. A single pair of glasses can accommodate different body positions and activity requirements by adjusting the nose pad to various predetermined positions, eliminating the need for multiple specialized glasses sets

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Ease of operation

If the nose pad is adjusted during activities, then comfort and vision are improved, but the adjustment mechanism becomes more complex

Engineering Contradiction:

Improvenose pad height adjustmentVSAvoidadjustment mechanism

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The adjustment mechanism is pre-configured with predetermined positions marked by positioning holes and corresponding stops. These positions are established during manufacturing, allowing the user to simply select from pre-defined optimal positions rather than requiring complex real-time adjustment calculations or mechanisms

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The adjustment mechanism uses simple, inexpensive components such as positioning holes, pins, and elastic stops rather than complex mechanical systems. These basic elements provide sufficient adjustment functionality without requiring expensive or complicated mechanisms, maintaining ease of operation while controlling complexity

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)
