Radiation Protection Envelope with Drainage Channels

Solution Overview

Problem

Existing individual protection devices for ionizing radiations, such as X-rays, are difficult to wash and sanitize due to their structure, which allows water to enter the shielding core and leads to prolonged drying times, making them inadequate for frequent use.

Innovation Solution

The device incorporates a waterproof covering envelope with drainage means, such as net-shaped elements and drainage openings, positioned at the lower portions to facilitate water exit during washing, allowing for rapid drying and effective sanitization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If individual protection devices are made with a waterproof envelope and shielding core, then radiation protection is improved, but washing and drying becomes difficult

Engineering Contradiction:

Improveradiation protectionVSAvoidwashing ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The envelope is divided into multiple chambers separated by partitions, with each chamber containing a drainage channel. This segmentation allows water to be efficiently drained from different regions of the envelope simultaneously, solving the washing difficulty while maintaining the waterproof protective function.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Drainage channels and openings are introduced as intermediary structures within the envelope. These channels act as mediators that facilitate water removal from the interior space during washing, enabling effective cleaning without compromising the radiation shielding integrity.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If individual protection devices are washed by dipping in water, then sanitization is attempted, but water enters the envelope and cannot drain

Engineering Contradiction:

ImprovecontaminationVSAvoidwashing effectiveness

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

Drainage channels and openings are introduced as intermediary structures within the envelope. These channels act as mediators that facilitate water removal from the interior space during washing, enabling effective cleaning without compromising the radiation shielding integrity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The envelope incorporates drainage openings that allow controlled passage of water and air. This porous approach enables effective sanitization by allowing water to enter and exit the envelope freely, while the drainage channels ensure complete water removal.

Inventive Principle:

Principle #31Porous materials
