Solution Overview

Problem

Conventional eyewear with pivotable temples connected by small screws is time-consuming to assemble, adds weight, and may loosen or fall out due to frequent folding and unfolding.

Innovation Solution

The eyewear features temples with a fixed segment, a movable segment, connecting portions, and an elastic portion, allowing for integral formation and pivotable movement between open and folded positions without screws, utilizing polypropylene or polyamide materials for the lens unit and temples.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If screws are used to connect temples to the frame, then the temples can be pivotally connected, but the assembly process becomes time-consuming and the screws may loosen or fall out after numerous folding and unfolding movements

Engineering Contradiction:

Improveconnection reliabilityVSAvoidassembly time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The temple and frame are merged into a single integrally formed component, eliminating the need for separate screws to connect the temples to the frame. This integration resolves the technical contradiction by removing the connection reliability issues and assembly time consumption associated with screw fastening, while maintaining the pivotal movement functionality through the integrated hinge structure.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The screws are extracted and removed from the design entirely. By taking out the screw fastening mechanism, the patent eliminates the problems of screws loosening or falling out after numerous folding and unfolding movements, as well as the time-consuming assembly process, while achieving the same connection function through integral formation.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If screws are used to connect temples to the frame, then the temples can be pivotally connected, but the screws add weight to the eyewear

Engineering Contradiction:

Improveconnection reliabilityVSAvoideyewear weight

Core Design Contradiction:

ReliabilityVSWeight of moving object

Solution Approach 1:

The temple and frame are merged into a single integrally formed component, eliminating the need for separate screws. This integration removes the additional weight contributed by screws while maintaining the connection reliability through the unified structure, thus resolving the contradiction between connection reliability and eyewear weight.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The screws are extracted and removed from the design entirely. By eliminating the screw fastening mechanism, the patent reduces the overall weight of the eyewear while maintaining reliable temple connection through the integral formation, resolving the contradiction between connection reliability and weight.

Inventive Principle:

Principle #2Taking out (Extraction)

3Reliability

If screws are used to connect temples to the frame, then the temples can be pivotally connected, but the manufacturing process becomes more complex

Engineering Contradiction:

Improveconnection reliabilityVSAvoidmanufacturing ease

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The temple and frame are merged into a single integrally formed component, eliminating the need for separate screw fastening parts and assembly steps. This integration simplifies the manufacturing process by reducing the number of components and assembly operations, while maintaining connection reliability through the unified structure.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The screws and associated fastening mechanisms are extracted and removed from the design. This elimination simplifies manufacturing by reducing part count and assembly complexity, while the integral formation ensures reliable connection without requiring separate fastening components.

Function Achieved in This Case

This design reduces manufacturing costs, eliminates screw-related issues, and provides a lightweight, secure folding mechanism for the eyewear.

Implementation Method 1

The elastic portion is flexible, and is integrally formed with and interconnects the fixed segment and the movable segment such that, when the movable segment is moved between the open position and the folded position, the elastic portion is deformed for generating a restoring force

AI summary

An eyewear includes a lens unit and two temples each having a fixed segment, a movable segment, at least one connecting portion and a flexible elastic portion. For each temple, the connecting portion interconnects the fixed segment and the movable segment. The movable segment is pivotable between an open position and a folded position. The elastic portion is integrally formed with and interconnects the fixed segment and the movable segment. When the movable segment is moved between the open position and the folded position, the elastic portion is deformed for generating a restoring force to drive the movable segment to pivot to one of the open position and the folded position from the other one of the open position and the folded position.
