Solution Overview

Problem

Existing eyeglasses require significant customization and are inflexible, leading to time-consuming assembly and limited options for users, who often need to purchase multiple pairs for different situations, resulting in cost and inconvenience.

Innovation Solution

Modular spectacles that can be assembled and disassembled without tools, featuring a frame assembly with interchangeable lenses and temples, allowing for quick changes in style and color without the need for specialized tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If lenses are permanently secured to the frame using screws or rivets, then the structural stability is improved, but the ease of assembly and disassembly deteriorates

Engineering Contradiction:

Improvestructural stabilityVSAvoidease of assembly and disassembly

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The frame is divided into multiple separable components (front frame element, middle frame element, rear frame element) that can be easily assembled and disassembled through alignment of slots, eliminating the need for permanent fastening methods while maintaining structural integrity during use

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Slots are introduced as intermediary structural features that enable temporary yet stable connection between frame elements and temples, allowing for tool-free assembly and disassembly while providing sufficient structural stability during wearing

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If custom lenses are used to fit precisely within the frame configuration, then the manufacturing precision is improved, but the adaptability deteriorates

Engineering Contradiction:

Improvelens-to-frame fit precisionVSAvoidframe selection flexibility

Core Design Contradiction:

Manufacturing precisionVSAdaptability or versatility

Solution Approach 1:

The frame design with standardized slots and rim structures serves multiple functions: it provides precise lens mounting, allows easy disassembly, enables temple interchangeability, and accommodates different frame styles (full-rim, half-rim, rimless), making a single frame assembly compatible with various lens and temple combinations

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

By separating the frame into modular elements with standardized interfaces (slots and rims), the system allows precise lens fitting within each configuration while enabling users to switch between different frame styles and temple options without requiring custom-made frames for each variation

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If multiple different eyeglasses are purchased for different situations, then the adaptability is improved, but the loss of substance deteriorates

Engineering Contradiction:

Improvesituation-specific lens optionsVSAvoidcost of purchasing multiple pairs

Core Design Contradiction:

Adaptability or versatilityVSLoss of substance

Solution Approach 1:

A single frame assembly with interchangeable temples and lens configurations serves multiple purposes: users can switch between different temple styles for different occasions, change lens types (prescription, sunglasses, reading), and adjust frame appearance without purchasing multiple complete eyeglass pairs, significantly reducing overall cost

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Instead of discarding entire eyeglass pairs when changing styles or lens requirements, users can retain the frame assembly and simply interchange temples or lens elements, recovering the value of the frame investment and only replacing the specific component that needs changing

Inventive Principle:

Principle #34Discarding and recovering

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This solution provides users with a versatile and cost-effective option for eyeglasses, allowing a single pair of lenses to be easily converted between styles and colors, reducing the need for multiple pairs and saving time and money.

Implementation Method 1

a pair of temples with compressible ends that fit securely within the slots in the front, rear and middle frame elements, such that when said compressible ends are compressed, inserted into said slots, and released, said compressible ends expand and are secured within said slots

AI summary

Modular spectacles that are assembled and disassembled without the use of tools are disclosed. The modular spectacles comprise a pair of lenses, a middle frame element including a pair of rims for accepting the pair of lenses and a slot on each side, a front frame element with a slot on each side of the front frame element, wherein portions of the front frame element extend over portions of the pair of rims of the middle frame element, a rear frame element similar to the front frame element, and a pair of temples with compressible ends that fit securely within the slots, wherein the lenses are placed within the rims, the middle frame element is placed between the front and rear frame elements, and the temples are inserted into the slots, such that the frame elements are secured together, and the lenses are held in place by the frame elements.
