Solution Overview

Problem

Conventional imaging devices for animal test subjects fail to accurately capture changes and influences on the test subject when applying external stimuli, lacking the capability to obtain precise measurements and real-time imaging.

Innovation Solution

An imaging device with a movable test subject supporter, fastening device, and integrated image capturing technologies like optical, X-ray, or MRI, along with an excitation energy source and image processing system, allowing for real-time imaging of changes in animal subjects during external stimulus application, with features such as a sliding supporter, fastening device, and external light shielding.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If the animal is completely enclosed in the darkroom box for imaging, then external light interference is blocked, but the ability to apply external stimulus and observe real-time changes is lost

Engineering Contradiction:
Improveexternal light interferenceVSAvoidcapability to apply external stimulus and observe changes
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The darkroom box is divided into two functional zones: a stimulus application zone with an opening for external access, and an imaging zone that remains enclosed. This segmentation allows simultaneous external stimulus application and internal imaging without light interference

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The opening in the darkroom box extracts the stimulus application function from the enclosed imaging environment, allowing external stimuli to be applied while maintaining the light-blocking capability for imaging

Inventive Principle:
Principle #2Taking out (Extraction)

2Manufacturing precision

If the animal is restrained completely to prevent motion, then imaging clarity is improved, but the animal's natural behavior and response to stimulus are suppressed

Engineering Contradiction:
Improveimaging clarityVSAvoidaccuracy of behavioral response measurement
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The restraint mechanism applies localized restraint only to the body region being imaged, while leaving other body parts free to move and respond naturally to stimuli. This selective restraint maintains both imaging clarity and behavioral accuracy

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The restraint mechanism is designed to be dynamic rather than rigid, allowing controlled movement in non-imaged regions while maintaining stability in the imaged region, enabling natural behavioral responses without compromising image quality

Inventive Principle:
Principle #15Dynamics

3Loss of information

If multiple imaging devices are used to capture different aspects of the animal, then comprehensive data is obtained, but device complexity and space requirements increase

Engineering Contradiction:
Improvecompleteness of imaging dataVSAvoidnumber of imaging devices and space requirements
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

Multiple imaging devices are merged into a single integrated imaging chamber, allowing simultaneous or sequential operation of different imaging modalities (e.g., MRI, CT, optical imaging) within the same confined space, reducing overall system complexity and space requirements

Inventive Principle:
Principle #5Merging (Combining)
