Radiation-Protective Glasses Frame with Integrated Dosimeter Holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal protective equipment (PPE) against ionizing radiation does not allow accurate measurement of radiation dose received by the user's eyes without bulky auxiliary devices, and it is important to ensure safe, comfortable operation.
Innovation Solution
A frame for protective glasses with integrated dosimeter holders positioned close to the eyes, allowing precise measurement of ionizing radiation dose, featuring ergonomic design and removable dosimeter mounts for versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protective eyewear is made with radio-attenuating material to reduce radiation dose, then protection against ionizing radiation is improved, but the ability to measure radiation dose accurately at the eyes is worsened without auxiliary devices
Solution Approach 1:
The patent combines the protective function and measurement function into a single integrated device. The dosimeter holder is built into the frame structure itself, merging the protective eyewear with the radiation dosimetry function. This eliminates the need for separate auxiliary measuring devices and enables accurate measurement of radiation dose at the eye level while maintaining protection.
Solution Approach 2:
The frame serves multiple functions simultaneously: it provides radiation protection through radio-attenuating material, houses the dosimeter for measurement, and maintains ergonomic wearability. The integrated design makes the protective eyewear a multi-functional device that both protects and monitors radiation exposure.
2Measurement precision
If auxiliary measuring devices are added to measure radiation dose, then measurement capability is improved, but device complexity and bulkiness increase
Solution Approach 1:
The dosimeter holder is integrated directly into the frame structure, combining the measurement device with the protective eyewear. This eliminates the need for separate auxiliary devices and reduces overall complexity while maintaining measurement capability.
Solution Approach 2:
The dosimeter is nested within the dosimeter holder that is itself integrated into the frame structure. This nested arrangement allows the measuring device to be compact and embedded within the protective eyewear, avoiding bulkiness while maintaining functionality.
3Ease of operation
If dosimeter is positioned away from eyes, then ease of operation is improved, but measurement accuracy of eye radiation dose deteriorates
Solution Approach 1:
The dosimeter holder is positioned at a specific location on the frame - the lateral extremity or corner area - which is optimally located to measure radiation dose at the eye level while maintaining ergonomic wearability. This localized positioning ensures both measurement accuracy and comfort.
Solution Approach 2:
The dosimeter holder can be positioned in different locations on the frame structure (lateral extremity, corner area, or protruding behind the front part) to optimize both measurement accuracy and wearability. The frame's three-dimensional structure provides multiple viable positions for the dosimeter.
