Solution Overview

Problem

Conventional nose pad-less eyeglass frames fail to adapt to varying face sizes, leading to insufficient fixation force and potential frame displacement due to fixed pad positions.

Innovation Solution

The eyeglass frame features movable supporting members attached to temples, comprising base portions, cheekbone pad portions, and coupling arms, with adjustable longitudinal channels and slits or through-holes, allowing the supporting members to slide and adjust for optimal positioning on the cheekbones, ensuring stable fixation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed-position pads are used on temples, then the structure is simple, but the fixation force is insufficient and the frame cannot adapt to different face sizes

Engineering Contradiction:

Improveadaptability to face sizeVSAvoidstructure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The supporting member is designed with a movable base portion that can slide along the temple in the longitudinal direction. This dynamic structure allows the supporting member to adjust its position according to different face sizes and wearer preferences, transforming a static structure into an adaptive one that maintains effective fixation across various users without requiring multiple fixed-position designs

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The supporting member is divided into distinct functional segments: a base portion that slides on the temple, a coupling arm that connects to the pad, and the pad itself that contacts the face. This segmentation allows independent optimization of each component - the base portion provides adjustability, the coupling arm transmits force, and the pad provides comfort - while maintaining overall structural simplicity

Inventive Principle:

Principle #1Segmentation

2Reliability

If fixed-position supporting members are used, then manufacturing is simple, but positional deviations occur due to face movement

Engineering Contradiction:

Improvefixation stabilityVSAvoidmanufacturing complexity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The base portion is designed to slide along the temple rather than being fixed at a single position. This dynamic capability allows the supporting member to maintain optimal contact with the face even when the face moves slightly, preventing positional deviations and ensuring reliable fixation without requiring complex adjustment mechanisms

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The coupling arm is inserted into a longitudinal channel formed in the temple, creating a nested structure where the coupling arm moves within the confines of the temple. This nesting provides guidance and constraint while allowing the necessary sliding motion, ensuring the supporting member stays properly positioned without requiring additional external fastening components

Inventive Principle:

Principle #7Nested doll (Nesting)

3Object-affected harmful factors

If nose pads are used on the front portion, then fixation force is sufficient, but contact marks and makeup removal occur on the nose

Engineering Contradiction:

Improvecontact marks on faceVSAvoidfixation force

Core Design Contradiction:

Object-affected harmful factorsVSForce

Solution Approach 1:

The invention removes the nose pads from the front portion of the eyeglass frame entirely and relocates the supporting function to the temples. By extracting the pads from their traditional nose-contact position and placing them on the temples to contact the cheekbones instead, the harmful effect of nose contact marks is eliminated while the necessary fixation force is maintained through the temple-pad-cheekbone interface

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The supporting member acts as an intermediary structure that transfers the weight and fixation function from the traditional nose-pad interface to a new temple-pad-cheekbone interface. This intermediary mechanism allows the eyeglasses to be supported without direct nose contact, preventing contact marks while maintaining adequate fixation through the mediating supporting member

Inventive Principle:

Principle #24Intermediary (Mediator)
