Solution Overview

Problem

Conventional personal protective equipment (PPE) for healthcare professionals, such as lead aprons and gloves, fail to provide adequate shielding against ionizing radiation, especially in procedures where close proximity to the radiation source is necessary, and are cumbersome and uncomfortable due to their bulkiness and lack of ventilation.

Innovation Solution

A radiation shield device that covers patients while allowing selective access to target areas, featuring flaps that can be easily folded to expose specific regions, made from radiation-blocking materials like lead or lead-free composites, with pre-formed lines for easy manipulation and stability, and optionally includes antimicrobial layers and radiation detection capabilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If conventional lead protective clothing is used, then radiation shielding is provided, but the equipment becomes bulky and heavy, hindering movement and causing orthopaedic problems

Engineering Contradiction:
Improveradiation shieldingVSAvoidweight of PPE
Core Design Contradiction:
Object-affected harmful factorsVSWeight of moving object

Solution Approach 1:

The protective device is segmented into multiple flaps that can be independently positioned and folded. Each flap provides localized radiation protection while allowing selective access to different body areas, eliminating the need for a single bulky apron that covers the entire body.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The protective device transitions from a two-dimensional flat apron to a three-dimensional structure with flaps that can be folded and positioned in multiple configurations, allowing the patient's body to be covered while maintaining accessibility to target areas.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Object-affected harmful factors

If conventional lead protective clothing is used, then radiation shielding is provided, but the equipment lacks ventilation and breathability, increasing discomfort

Engineering Contradiction:
Improveradiation shieldingVSAvoidcomfort and breathability
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The protective device is divided into separate flaps that can be positioned only where radiation protection is needed, leaving other areas open for ventilation and comfort, rather than covering the entire body with a solid apron.

Inventive Principle:
Principle #1Segmentation

3Object-affected harmful factors

If blankets are used to limit radiation, then radiation exposure is reduced, but access to covered parts of the patient's body is restricted

Engineering Contradiction:
Improveradiation exposureVSAvoidaccess to target areas
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The protective device consists of multiple independent flaps that can be separately folded back or positioned to expose specific target areas while maintaining radiation protection over other body parts, allowing selective access during procedures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The flaps are designed to be dynamically repositionable during the procedure, allowing the operator to fold them back to access target areas and then return them to the shielding position when not in use, providing both protection and accessibility.

Inventive Principle:
Principle #15Dynamics

4Ease of operation

If conventional PPE does not cover the whole body surface, then mobility is improved, but health professionals remain exposed to direct and scattered radiation

Engineering Contradiction:
ImprovemobilityVSAvoidradiation exposure
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

Instead of protecting the health professional with a bulky apron, the protective device is placed on the patient's body, inverting the traditional approach by shielding the radiation source area rather than the operator, thereby protecting both while maintaining mobility.

Inventive Principle:
Principle #13The other way round (Inversion)
