Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If protective structures such as blouses, aprons, and thyroid protectors are used, then operators are protected against ionizing radiation, but the heavy weight is detrimental to operator comfort, limits mobility, and leads to rapid fatigue

Engineering Contradiction:

Improveradiation protectionVSAvoidoperator comfort and mobility

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The protective system is segmented into two parts: a fixed radiation protection screen that remains stationary, and removable protective clothing for the operator. This segmentation allows the bulk of the radiation protection to be in the fixed screen, reducing the weight and burden on the operator while maintaining comprehensive protection.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The heavy radiation protection function is extracted from the operator's clothing and placed into a fixed screen structure. The operator's clothing becomes minimal protective layers, while the screen承担s the primary radiation shielding function, thereby improving operator comfort and mobility.

Inventive Principle:

Principle #2Taking out (Extraction)

2Object-affected harmful factors

If traditional radiation protection screens are used, then operators are protected against radiation, but they are not adequately suited for echography techniques due to the presence of materials or equipment that must be handled during interventions

Engineering Contradiction:

Improveradiation protectionVSAvoidsuitability for echography techniques

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The screen incorporates a movable panel that can be dynamically adjusted during interventions. This movable panel creates a passage or opening that allows operators to reach through and manipulate echography equipment and materials while maintaining radiation protection, making the screen adaptable to echography techniques.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The screen has different functional zones: a fixed radiation-blocking portion and a local movable portion that allows selective access. This local quality differentiation enables the screen to provide radiation protection while accommodating the specific needs of echography interventions where equipment manipulation is required.

Inventive Principle:

Principle #3Local quality

3Object-affected harmful factors

If operators handle materials and equipment during interventions without support, then radiation protection is maintained, but operator fatigue increases and precision in gestures is reduced

Engineering Contradiction:

Improveradiation protectionVSAvoidprecision in gestures

Core Design Contradiction:

Object-affected harmful factorsVSMeasurement precision

Solution Approach 1:

The movable panel acts as an intermediary mechanism between the operator and the equipment. It provides a controlled access point that allows operators to manipulate equipment with better support and positioning, reducing fatigue and improving precision while maintaining radiation protection through the screen's structure.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The screen is designed with pre-configured openings and movable panels that anticipate the need for equipment manipulation during echography interventions. This preliminary design allows operators to access and position equipment optimally before interventions begin, reducing fatigue and improving gesture precision throughout the procedure.

Inventive Principle:

Principle #10Preliminary action

AI summary

Disclosed is a radiation protection screen for protecting an operator against emissions of ionizing radiation of the X-ray type or other types. This radiation protection screen includes a front wall provided with a transparent panel and with an airlock structure adapted to the passage of equipment and/or the arms of the operator. The airlock structure includes an airlock opening associated with a flexible closing structure, which airlock opening includes a horizontal or approximately horizontal lower opening edge. And the screen further includes a support device suitable for supporting material and/or an arm of the operator, which support device is arranged at the level of the lower opening edge of the airlock structure, on the side of the inner face of the front wall.
