Solution Overview

Problem

Cassette accommodating devices fail to establish stable electrical connections with cassettes of varying sizes due to lack of positional alignment, leading to inconsistent power supply and image data retrieval.

Innovation Solution

The device features a cassette accommodating system with sloping and inclined surfaces that guide cassettes into precise positional alignment, ensuring stable electrical contact through rechargeable battery electrodes and output electrodes, allowing for efficient power supply and image data transfer across different cassette sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a cassette accommodating device accommodates cassettes of different sizes without positional alignment, then the device can handle multiple cassette sizes, but stable electrical connection cannot be established

Engineering Contradiction:

Improveability to accommodate different cassette sizesVSAvoidelectrical connection stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The groove portion with sloping face and inclined bottom face is pre-formed in the cassette accommodating device to automatically guide and align cassettes of different sizes into a standardized position upon insertion, ensuring reliable electrical connection before any operational action occurs

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The groove portion acts as an intermediary alignment mechanism between the cassette and the electrical connection points, mediating the positioning process to ensure proper contact regardless of the cassette size

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If cassettes are inserted without guidance, then insertion is simple and quick, but positional alignment and electrical contact are inconsistent

Engineering Contradiction:

Improvecassette insertion simplicityVSAvoidpositional alignment accuracy

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The groove portion with sloping face enables cassettes to self-align during insertion through the inclined surface guidance, eliminating the need for external alignment tools or complex positioning mechanisms while ensuring consistent electrical contact

Inventive Principle:

Principle #25Self-service

AI summary

A cassette accommodating device accommodates casings of a plurality of sizes. Each casing is detachably inserted with a cassette installed with a rechargeable battery and a radiation detection unit that is supplied with power from the rechargeable battery and generates a radiographic image according to an amount of received radiation. Each casing is provided on at least one of two connected side faces with a power receiving unit that receives power for charging the rechargeable battery. The device comprises a groove portion, formed with a sloping face that faces one of the two side faces of an accommodated casing, and a bottom face that faces the other of the two side faces of the accommodated casing. The bottom face is inclined such that the casing moves toward the sloping face when the casing is accommodated. A power supply unit is formed to the sloping face and/or the bottom face so as to supply power to the power receiving unit when the casing has been accommodated.
