Existing methods fail to effectively observe and capture the deformation state of periodically deformed elastic materials, such as rubber or elastomers, at specific moments during deformation cycles.

Innovation Solution

A method and apparatus that involve capturing projection images of the elastic material from a direction perpendicular to its axis at multiple positions, deforming the material in predetermined cycles, and outputting capture signals at specific times to construct a three-dimensional image of the material's deformation state, using a system with a deforming mechanism, signal output device, and capturing means.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If radiation light is transmitted through the elastic material to obtain interior images, then the interior structure can be observed, but the deformation state at specific time points during periodic deformation cannot be captured

Engineering Contradiction:
Improveobservation capabilityVSAvoidtiming precision
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies periodic action by synchronizing the capture signal generation with the periodic deformation cycle of the elastic material. A capture signal is generated at a predetermined time point in each deformation cycle, enabling timed capture of the material's state at specific phases of its periodic deformation, thus resolving the inability to capture deformation states at specific moments

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The patent implements feedback by detecting the position of the elastic material during its periodic deformation and using this information to trigger capture signals at appropriate moments. The detection unit monitors the deformation cycle and provides feedback to the capture signal generation unit, ensuring precise timing of image capture relative to the deformation phase

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If the elastic material is deformed periodically to observe deformation, then deformation states can be studied, but the complexity of coordinating deformation with image capture increases

Engineering Contradiction:
Improvedeformation observation capabilityVSAvoidsystem coordination
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the deformation function and image capture function into a coordinated system. The deformation unit and capture unit operate in an integrated manner where the capture unit is triggered by the deformation cycle itself, eliminating the need for separate complex synchronization mechanisms and reducing overall system complexity while maintaining deformation observation capability

Inventive Principle:
Principle #5Merging (Combining)

3Manufacturing precision

If projection images are captured at multiple positions around the axis, then three-dimensional images can be constructed, but the time required to capture all positions increases

Engineering Contradiction:
Improvethree-dimensional image accuracyVSAvoidcapture speed
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent applies preliminary action by capturing projection images at multiple positions around the axis simultaneously or in rapid sequence at a predetermined time point during the deformation cycle. This allows the three-dimensional image construction to be based on pre-captured data from all necessary positions, eliminating the need for sequential capture over extended periods and thereby increasing capture speed while maintaining three-dimensional accuracy

Inventive Principle:
Principle #10Preliminary action
