Solution Overview

Problem

Existing radiographic imaging tables face challenges with cables and connectors interfering with imaging and limiting the imaged portion, especially when charging or transmitting data, and have fixed cassette inserting positions that restrict flexibility and comfort for both patients and operators.

Innovation Solution

A radiographic imaging table design featuring a test object mounting plate and a detector mounting plate with a connection device on the detector plate for charging and communication, allowing the radiographic image detector to move freely without protruding cables or connectors, and incorporating rails for easy movement and non-contact power supply through electromagnetic induction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the electronic cassette is inserted between the bed and the to-be-tested person to enable charging and data transmission, then the cable or connector can be positioned for charging, but the cable or connector interferes with the loading of the to-be-test person on the bed and the handling of the electronic cassette by an operator

Engineering Contradiction:

Improvecharging and data transmissionVSAvoidcable interference

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the cable and connector from the imaging area by positioning the connector on the bed frame rather than on the electronic cassette itself. This separates the charging function from the imaging operation, allowing the electronic cassette to move freely without cable interference while maintaining ease of charging and data transmission.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The bed frame serves as an intermediary structure that hosts the connector, mediating between the power source and the electronic cassette. This intermediary positioning allows the cable to be routed away from the imaging area, eliminating interference with patient loading and operator handling while preserving the charging function.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the electronic cassette is inserted between the bed and the to-be-tested person to enable charging, then the connector can be positioned for connection, but the to-be-tested person feels unpleasant

Engineering Contradiction:

ImprovechargingVSAvoidpatient discomfort

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the connector and cable from the space between the bed and the patient, relocating the connector to the bed frame. This removes the source of patient discomfort while preserving the charging capability, as the electronic cassette can still connect to the bed frame connector without being squeezed between the bed and patient body.

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of operation

If a fixed cassette inserting position is provided under the top board of the bed to enable charging, then the connector can be positioned for connection, but the photographable portion is limited

Engineering Contradiction:

ImprovechargingVSAvoidimaging flexibility

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent implements a movable electronic cassette that can be freely positioned on the bed frame rather than being fixed at a specific inserting position. The connector is positioned on the bed frame to accommodate this movement, allowing the electronic cassette to be relocated to image different portions of the patient while maintaining continuous charging and data transmission capabilities.
