Solution Overview

Problem

Conventional portable radiographic imaging devices fail to effectively suppress heat transmission from external sources and discharge internal heat, leading to temperature unevenness and suboptimal image quality due to inadequate thermal management.

Innovation Solution

A portable radiographic imaging device is designed with thermal insulation material on one face to prevent external heat transmission and a heat dissipation member on the opposite face to efficiently discharge internal heat, ensuring effective thermal management and orientation indicators for correct mounting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If thermal insulation material is provided on the first face to suppress external heat transmission, then heat transmission from external heat source is suppressed, but heat dissipation from internal components is hindered

Engineering Contradiction:

Improveexternal heat transmissionVSAvoidinternal heat dissipation

Core Design Contradiction:

Object-affected harmful factorsVSLoss of energy

Solution Approach 1:

The casing is divided into two distinct faces with different thermal functions: the first face is equipped with thermal insulation material to block external heat, while the second face is designed as a heat dissipation face without insulation to allow internal heat to escape. This segmentation resolves the contradiction by creating specialized zones for different thermal management needs.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different portions of the casing are assigned different thermal properties: the first face has high thermal insulation properties to prevent external heat entry, while the second face has high thermal conductivity properties to facilitate heat dissipation. This local differentiation allows simultaneous achievement of heat blocking and heat dissipation functions.

Inventive Principle:

Principle #3Local quality

2Object-affected harmful factors

If the portable radiographic imaging device is fixed to the trestle with the first face facing the mounting section, then external heat transmission is suppressed, but orientation must be precisely controlled

Engineering Contradiction:

Improveheat transmission suppressionVSAvoidmounting orientation

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

Indicator members are provided on the casing to visually indicate the correct orientation for mounting. These indicators (such as colored marks or symbols) make it easy to identify which face should face the mounting section, thereby simplifying the mounting operation while ensuring proper thermal management orientation.

3Temperature

If thermal insulation material is provided over the entire first face and heat dissipation member over the entire second face, then thermal management is most effective, but device complexity increases

Engineering Contradiction:

Improvethermal management efficiencyVSAvoidcasing structure

Core Design Contradiction:

TemperatureVSDevice complexity

Solution Approach 1:

The thermal management system utilizes parameter changes by providing thermal insulation material on the first face and heat dissipation members on the second face. This creates an asymmetric thermal parameter distribution across the casing surfaces, optimizing heat flow control while maintaining a relatively simple overall structure through functional differentiation rather than complex mechanisms.
