Solution Overview

Problem

Current eye protection measures for medical personnel exposed to X-rays, such as lead-glass goggles, are inadequate in providing complete shielding, especially with multiple X-ray sources, and existing solutions fail to allow safe viewing of the X-ray object while ensuring complete eye protection.

Innovation Solution

A radiation protection apparatus featuring a lead-based or equivalent shielding that encloses the eyes with a dynamic, delay-free stereoscopic display system, allowing medical personnel to view a real-time, three-dimensional image of the scene in front of them without exposing their eyes to X-rays, with adjustable optics and cameras for optimal vision and comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If lead-glass goggles are used for eye protection, then some radiation shielding is achieved, but complete shielding is difficult to achieve especially with multiple X-ray tubes

Engineering Contradiction:
Improveradiation exposure to eyesVSAvoidadequacy of protection
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The protective apparatus is divided into multiple independent shielding elements (lead glass plates, temple plates, side shields) that can be positioned at different locations around the eyes. Each segment provides localized protection, and together they create comprehensive coverage that addresses the limitation of single-piece goggles against multiple X-ray sources.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements a nested structure where the lead glass plate is positioned within a frame, temple plates are attached to the sides of the frame, and additional side shields are integrated into the temple area. This nested arrangement allows multiple protective layers to work together, with each layer providing additional shielding to achieve near 100% protection.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Object-affected harmful factors

If traditional protective glasses are used, then some protection is provided, but they do not allow viewing of the X-ray object while ensuring complete eye protection

Engineering Contradiction:
Improveradiation shieldingVSAvoidviewing capability
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent applies different properties to different parts of the protective apparatus: the front lead glass plate provides radiation shielding while maintaining optical transparency for viewing, the temple plates and side shields provide additional radiation protection, and the overall frame structure provides mechanical support and positioning. This local differentiation allows simultaneous achievement of protection and viewing capability.

Inventive Principle:
Principle #3Local quality

3Object-affected harmful factors

If lead shielding is added to achieve better protection, then radiation shielding improves, but the device complexity increases

Engineering Contradiction:
Improveradiation shielding effectivenessVSAvoidstructure complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The frame structure serves multiple functions: it provides mechanical support for the lead glass plate, positions the temple plates, supports side shields, and maintains the overall geometric arrangement of protective elements. This multi-functionality reduces the need for additional separate components, thereby limiting complexity increase despite enhanced shielding.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

The invention relates to an apparatus for protecting eyes from radiation, in particular for protecting the lenses of medical staff from X-ray or other ionizing radiation during medical examinations. The aim of the invention is to devise an apparatus which is easy to use and ensures that eyes are shielded from X-ray radiation but that the wearer nevertheless has the best working and visual conditions. This is achieved in that a housing (1) consists of a shell-like frame (2) which surrounds the eye region and, laterally, the temples of the wearer, in that the shell-like frame is provided with a holding device (3) for placement on the head and with a bridge part (4) for positioning on the bridge of the nose, in that the frame (2) is provided with a front-side opening (5) in which a shield (6) that is impermeable to X-ray radiation is fitted and in that at least one reproduction device (9) for stereoscopically reproducing video information is provided within the frame (2) on the rear side of the shield (6) facing the eyes, said reproduction device being coupled to an optical recording device or a camera (10) which is provided on the side of the shield (6) facing away from the eyes of the wearer.
