Solution Overview

Problem

Existing mobile radiation protection arrangements are cumbersome and require multiple personnel to move during interventional treatments, lacking ease of use and adequate radiation protection at all heights, especially when operating medical instruments.

Innovation Solution

A mobile radiation protection arrangement featuring a two-part frame with height-adjustable flexible radiation protection curtains that overlap, allowing for single-person operation and complete radiation protection at any height, with a chassis design enabling easy access to foot switches without opening the curtain.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If rigid radiation protection walls are used, then radiation protection is provided, but the weight of the radiation protection arrangement increases significantly

Engineering Contradiction:
Improveradiation protectionVSAvoidweight of radiation protection arrangement
Core Design Contradiction:
Object-affected harmful factorsVSWeight of moving object

Solution Approach 1:

The patent replaces rigid radiation protection walls with flexible radiation protection curtains made of lead-free, flexible material. These curtains can be easily moved and adjusted while maintaining radiation protection effectiveness, directly resolving the contradiction between protection capability and weight/mobility.

Inventive Principle:
Principle #30Flexible shells and thin films

2Ease of operation

If a single flexible radiation protection curtain is used, then mobility is improved, but radiation protection gaps may occur at different heights

Engineering Contradiction:
Improvemobility of radiation protection arrangementVSAvoidradiation protection coverage
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent combines multiple flexible radiation protection curtains of different lengths on a single mobile stand. The curtains are arranged to overlap with each other, ensuring continuous radiation protection across all height levels while maintaining the mobility benefits of flexible materials.

Inventive Principle:
Principle #5Merging (Combining)

3Object-affected harmful factors

If the radiation protection curtain extends to the lower edge of the frame, then complete radiation protection is achieved, but access to foot switches becomes difficult

Engineering Contradiction:
Improveradiation protection coverageVSAvoidaccess to foot switches
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent segments the radiation protection arrangement by using multiple curtains of different lengths. The lower curtain extends to the bottom edge for complete protection, while the upper curtain is positioned to allow foot access. This segmentation resolves the contradiction between complete protection and operational accessibility.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different curtain lengths at different locations/heights to meet different functional requirements. The lower area has full coverage for protection, while the upper area has reduced coverage to allow foot switch access, optimizing both protection and operability locally.

Inventive Principle:
Principle #3Local quality

4Stability of the object's composition

If multiple personnel are required to move the radiation protection arrangement, then stability is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvestability of radiation protection arrangementVSAvoidease of movement
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent employs a mobile stand with a heavy base that provides counterweight stability. This allows the lightweight flexible radiation protection curtains to be easily moved by one person while the heavy base ensures the arrangement remains stable during use, resolving the contradiction between ease of movement and stability.

Inventive Principle:
Principle #8Anti-weight (Counterweight)
