Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current laser safety measures for medical and cosmetic procedures lack integrated systems that provide real-time information and control over laser parameters while ensuring protection from various wavelengths of laser radiation, which can lead to eye injuries due to the limitations of existing protective eyewear and lack of intuitive control interfaces.
Innovation Solution
Laser safety glasses with see-through lenses that incorporate a projector and sensors to display and control laser parameters, allowing operators to interact with virtual controllers using hand or finger movements, and a foot switch for activating the laser, while ensuring protection by filtering specific wavelengths of laser energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional laser safety eyewear is used to filter specific wavelengths, then eye protection is provided, but real-time information and control capabilities are lost
Solution Approach 1:
The patent combines laser safety filtering lenses with an integrated imaging and display system. The safety glasses include a camera that captures real-time images of the treatment area, processes them, and displays them on an OLED screen embedded in the lens, allowing the operator to see both the filtered laser wavelengths for safety and the processed visual information for control.
Solution Approach 2:
The safety glasses serve multiple functions simultaneously: they filter harmful laser wavelengths to protect the operator's eyes, capture images of the treatment area via an integrated camera, process these images through algorithms, and display the processed information on an embedded screen. This multi-functional design eliminates the need for separate protective eyewear and control devices.
2Manufacturing precision
If complex control interfaces are used to manage laser parameters, then precise control is achieved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces traditional mechanical control interfaces (buttons, knobs, physical controls) with a gesture-based control system. The camera captures hand gestures, processes them through image processing algorithms, and translates them into laser parameter adjustments. This allows precise control of laser parameters through intuitive hand movements rather than complex physical interfaces.
Solution Approach 2:
The system creates a virtual representation of the treatment area and control interface through captured images and processed displays. Instead of directly manipulating physical controls, the operator interacts with visual representations of parameters and settings displayed on the screen, making control more intuitive and easier to operate.
3Reliability
If multiple filters are used to protect against multiple wavelengths, then comprehensive protection is provided, but device complexity increases
Solution Approach 1:
The patent uses composite filtering materials that can block multiple laser wavelengths simultaneously within a single lens structure. Rather than layering multiple separate filters, the lens is made from or coated with composite materials that have broad-spectrum laser blocking properties, providing comprehensive protection while maintaining a simple single-lens design.
