Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing fixtures for fixing patients during X-ray imaging, such as those with bedridden contractures, restless patients, children, or newborns, often suffer from poor fixing force, limited adjustment angles, and interference with image quality due to ghosting issues.

Innovation Solution

An auxiliary frame designed to accommodate a flat panel detector with strategically positioned fixing structures and a fixing belt system, where the distance between the fixing structures is optimized to minimize interference with the detector's sensing region, allowing for improved patient fixation and image quality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fixing belts are used to fix patients during X-ray imaging, then patient fixation is improved, but image quality deteriorates due to ghosting

Engineering Contradiction:

Improvepatient fixationVSAvoidimage quality

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The fixing structures are extracted from the detector surface and positioned on the frame surrounding the detector. This separation removes the fixing belts from the sensing region, eliminating ghosting while preserving patient fixation capability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The frame serves as an intermediary structure between the detector and the fixing belt. The fixing belt attaches to the frame rather than directly to the detector, mediating the fixation function while protecting the detector from interference

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If fixing structures are positioned closer to the detector edge, then patient fixation is improved, but detector sensing region is blocked

Engineering Contradiction:

Improvefixing forceVSAvoidsensing region

Core Design Contradiction:

ReliabilityVSArea of stationary object

Solution Approach 1:

The fixing structures are positioned in specific locations on the frame where they provide maximum fixation effectiveness while maintaining optimal distance from the detector's sensing region. Each fixing structure's position is optimized for its local function without compromising the overall detector area

Inventive Principle:

Principle #3Local quality

3Reliability

If existing fixtures are used to fix patients, then patient fixation is achieved, but adjustment angles are limited

Engineering Contradiction:

Improvepatient fixationVSAvoidadjustment angles

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The frame and detector assembly can be dynamically adjusted to different angles and positions. The fixing structures on the frame allow the detector to be positioned at various angles relative to the patient, providing versatility while maintaining secure fixation

Inventive Principle:

Principle #15Dynamics

AI summary

An auxiliary frame for accommodating a flat panel detector is provided. A first side of the auxiliary frame includes two first fixing structures. The two first fixing structures are adjacent to a first edge of the flat panel detector and are respectively located on two sides of a first center axis of the flat panel detector. The first edge of the flat panel detector has a first length. A distance between the two first fixing structures is greater than or equal to half of the first length and less than the first length.
