Removable Inner Lens Frame for Prescription Wraparound Eyewear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users with prescription lenses cannot effectively use performance-type wraparound eyewear without resorting to contact lenses or compromising on vision accuracy due to the lack of adaptable solutions for integrating prescription lenses with protective eyewear.
Innovation Solution
The design of eyewear featuring a removable inner frame and lens system, where the inner prescription lens is securely positioned within an inner frame that can be easily attached to an outer frame with a snap-fit mechanism, allowing for quick replacement and integration with an outer lens for sun and wind protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If users wear performance-type wraparound lenses for sun and wind protection, then protection from sun and wind is improved, but vision accuracy deteriorates due to inability to integrate prescription lenses
Solution Approach 1:
The eyewear is divided into two separate lens systems: an outer lens providing sun and wind protection, and an inner prescription lens providing vision correction. These segmented lens systems work together to simultaneously achieve both protection and visual accuracy that cannot be achieved with a single lens.
Solution Approach 2:
The inner frame with the prescription lens is nested within the outer frame structure. The inner frame is positioned inside the outer frame such that the prescription lens is held in close proximity to the outer lens, allowing both lenses to function simultaneously without interfering with each other.
2Measurement precision
If users wear contact lenses to achieve clear vision, then vision accuracy is improved, but comfort and convenience deteriorate due to lack of protection from sun and wind
Solution Approach 1:
The invention merges two previously separate solutions (contact lenses for vision correction and wraparound sunglasses for protection) into a single integrated eyewear system. The combination of inner prescription lens and outer protective lens in one frame structure allows users to achieve both clear vision and environmental protection simultaneously.
3Measurement precision
If prescription lenses are integrated into protective eyewear, then vision accuracy and protection are improved, but device complexity increases due to multiple lens and frame components
Solution Approach 1:
The inner frame is designed to be movable relative to the outer frame, allowing it to be adjusted to different positions or removed entirely. This dynamic design provides flexibility, allowing users to adapt the eyewear to different conditions (e.g., removing the inner frame when prescription correction is not needed) while simplifying the overall structure when the inner frame is not in use.
4Adaptability or versatility
If a removable inner frame system is implemented, then adaptability is improved, but ease of operation deteriorates due to additional steps for attaching and detaching lenses
Solution Approach 1:
The attachment mechanism between the inner and outer frames is replaced with a magnetic coupling system. The magnetic attraction force automatically holds the inner frame in place when attached to the outer frame, eliminating the need for complex mechanical fasteners, screws, or clips. This magnetic system provides both secure attachment and easy removal by simply pulling the inner frame away from the outer frame.

AI summary
Eyewear includes an outer frame having a right temple arm and a left temple arm. An outer lens is secured to the outer frame. An inner frame is removably secured to the outer frame. An inner lens is positioned in the inner frame. A portion of the outer lens engages the inner frame to removably secure the inner frame to the outer frame.
