Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a conventional fixed cylinder is used for rodent movement analysis, then the device structure is simple, but the experiment time is long and individual variations affect results

Engineering Contradiction:

Improveexperiment timeVSAvoiddevice structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent applies the dynamics principle by making the cylindrical space adjustable rather than fixed. The adjustment unit with movable adjustment plates allows the space dimensions to be changed during experiments, enabling active stimulation of rodent movement through space variation, which shortens experiment time while maintaining structural feasibility

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent segments the cylindrical space into adjustable sections using multiple adjustment plates that can be independently positioned. This segmentation allows flexible modification of the space configuration without redesigning the entire device structure, thus reducing experiment time while keeping the device relatively simple

Inventive Principle:

Principle #1Segmentation

2Reliability

If passive rodent behavior is observed without stimulation, then the device structure is simple, but individual variations create experimental variables

Engineering Contradiction:

Improveexperiment results consistencyVSAvoiddevice structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The adjustable space configuration allows researchers to dynamically modify the cylindrical environment to actively stimulate rodent movement. By varying the space dimensions, the device reduces the impact of individual rodent variations and fatigue, producing more reliable and consistent experimental results

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the spatial parameters of the cylindrical space by adjusting the position of adjustment plates. This parameter modification actively stimulates rodent behavior and reduces individual variations, improving result consistency without requiring complex additional components

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If the cylindrical space is fixed, then the device is easy to manufacture, but it cannot actively stimulate rodent movement

Engineering Contradiction:

Improverodent movement stimulationVSAvoiddevice manufacturing

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The patent implements a movable adjustment unit with adjustment plates that can be positioned at different locations within the cylinder. This dynamic structure enables active stimulation of rodent movement by varying the available space, while the design uses simple transparent resin materials and basic mechanical components to maintain ease of manufacture

Inventive Principle:

Principle #15Dynamics

4Adaptability or versatility

If a transparent plastic cylinder is used, then the device is simple and visible, but it cannot be adjusted to change rodent behavior

Engineering Contradiction:

Improvespace adjustment capabilityVSAvoiddevice structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the cylindrical space into adjustable segments using multiple adjustment plates that can be independently positioned at different heights and locations. This segmentation provides adaptability to change rodent behavior through space modification, while the modular design keeps the overall device structure manageable and not overly complex

Inventive Principle:

Principle #1Segmentation

AI summary

A movement analysis device for rodents capable of variably adjusting a space where a rodent is placed in order to stimulate the behavior of the rodent so that motor functions of the rodent can be analyzed more effectively. The movement analysis device for rodents includes a body including a pair of side plates distanced from each other with a predetermined gap and a connector plate connecting one ends of the side plates together, the connector plate having a slit extending from one to the other one of the side plates; and an adjustment unit including an adjustment plate configured insertable between the side plates of the body and into the slit of the connector plate of the body and a support plate extending to a height reaching from a bottom to the slit to support the adjustment plate at one portion thereof. The support plate is semi-cylindrically shaped to form a cylindrical space together with the connector plate.
