Slip-in Laser Insert for Protective Loupes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective eyewear for laser users with magnifying loupes is cumbersome due to the need for assembly before use, as the laser protective filters must be positioned against the back or inside of the eyeglasses, which is inconvenient during dental or medical procedures where laser protection is not always required.
Innovation Solution
A protective loupes eyewear assembly featuring a slip-in insert structure with notches and tab members that mates with the eyewear frame, allowing easy positioning and removal of a laser-absorbing lens insert behind the eyewear frame, providing quick and secure laser protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If laser protective filter lenses are positioned against the back or inside of eyeglasses with loupes, then eye protection from laser radiation is achieved, but the assembly complexity and difficulty of quick installation/removal increase
Solution Approach 1:
The protective system is divided into separate components: the permanent eyeglass frame with loupes and the removable laser protective insert. This segmentation allows the protective function to be added only when needed, without permanently modifying the eyeglass structure.
Solution Approach 2:
The laser protective insert is designed to be dynamically removable and reinsertable, allowing users to adapt the protection level based on procedural needs. The tab members enable quick insertion and removal without tools, transforming a static eyeglass structure into a dynamic protective system.
2Object-affected harmful factors
If laser protective filters are permanently integrated into eyeglasses with loupes, then continuous eye protection is provided, but the ease of operation and convenience during procedures decrease
Solution Approach 1:
The removable insert design allows the protective function to be activated only when laser procedures are performed. Users can quickly insert the protective lens when needed and remove it when not needed, providing operational flexibility that permanently integrated filters cannot offer.
Solution Approach 2:
The laser protective function is extracted as a separate removable component rather than being permanently built into the eyeglass frame. This extraction allows users to take the protection with them when needed and leave it behind when not needed, enhancing operational convenience.
3Object-affected harmful factors
If laser protective lenses are positioned inside loupes eyewear, then comprehensive eye protection is achieved, but the time required for assembly and preparation increases
Solution Approach 1:
The laser protective insert is pre-formed with tab members and positioning features that enable quick installation. The notches in the eyeglass frame are pre-positioned to guide rapid insertion, reducing assembly time to a few seconds without compromising protection.
Solution Approach 2:
By segmenting the protective system into a removable insert, the assembly process is simplified to a single insertion action rather than requiring complex multi-step assembly of permanent components.
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
Enables easy and secure laser protection for dental or medical professionals by allowing the protective insert to be easily slipped in and out during procedures, enhancing convenience and safety without compromising vision or assembly complexity.
Implementation Method 1
The insert assembly has a lens structure which absorbs laser light of a specified wavelength or wavelength range

AI summary
A protective loupes eyewear assembly having an eyewear frame with magnifying loupes. The eyewear frame has notches in the top of the frame and a bottom shelf structure on the inside of the frame. An insert assembly with a pair of outwardly extending tabs and a mating configuration is constructed to slip into the notches at the top of the eyewear frame and into a bottom shelf structure behind the eyewear frame to provide laser protection for use in the dental, surgical and other arts.
