Eyewear Chassis Insert Clips for Interchangeable Lens Profiles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing eyewear designs with interchangeable lenses are unsuitable for corrective lenses due to varying thicknesses and lack versatility in size, shape, purpose, and appearance, as they require standard measurements and are not adaptable for different lens profiles.
Innovation Solution
An eyewear apparatus comprising a chassis insert frame that securely holds lenses with a tapered nose bridge and angled temple portions, allowing for interchangeable lenses of various thicknesses and shapes, with a frame that accommodates different lens profiles through adjustable notches and protrusions for secure engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If standard lens measurements and fixed frame designs are used, then manufacturing and assembly are simplified, but versatility in terms of size, shape, purpose, and appearance is limited
Solution Approach 1:
The eyewear system is divided into separate modular components: a frame and interchangeable lens inserts. Each lens insert is a complete functional unit with its own mounting mechanism, allowing independent design optimization while maintaining ease of assembly through standardized insertion into the frame.
Solution Approach 2:
The frame is designed with universal mounting features (grooves, notches, protrusions) that can accommodate multiple types of lens inserts with different sizes, shapes, and functions. This multi-functional design allows a single frame to serve various purposes by simply changing the lens insert.
2Device complexity
If lenses are individually attached at nosepiece and temple with fixed attachment points, then assembly is simplified, but adaptability to various lens thicknesses and profiles is reduced
Solution Approach 1:
The attachment mechanism incorporates adjustable and flexible elements including elastic bands, spring-loaded protrusions, and movable notches that can adapt to different lens thicknesses and profiles. This dynamic design maintains relatively simple assembly while accommodating variety in lens characteristics.
Solution Approach 2:
Different portions of the lens insert have different structural characteristics - the nosepiece area has specific engagement features while the temple areas have different attachment mechanisms. This localized differentiation allows each region to be optimized for its specific function while maintaining overall system simplicity.
3Adaptability or versatility
If corrective lenses with varying thicknesses are used, then functional requirements are met, but compatibility with standard frames becomes difficult
Solution Approach 1:
The lens insert is completely nested within the frame structure, with the lens surrounded by a protective and supportive frame that provides consistent mounting geometry regardless of the lens thickness. This nesting approach ensures reliable compatibility by isolating the variable (lens thickness) from the fixed mounting points.
Solution Approach 2:
The lens insert frame acts as an intermediary between the corrective lens and the main eyewear frame. This intermediate structure standardizes the interface, allowing lenses of varying thicknesses to be accommodated through a consistent mounting mechanism that ensures reliable compatibility.

AI summary
An eyewear apparatus with interchangeable insert chassis components that may insert into a frame structure in accordance with a specific mechanical interlocking apparatus. In particular, the contour of the insert chassis may conform to the contour of a channel in the frame, and tabs or notches in the chassis insert may snap into a hole, tab, or indentation in the nose of the frame, and at either side of the frame near the temples, as described herein.
