Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If continuous irradiation of high- and low-energy X-rays is performed to obtain clear images, then image quality is improved, but image blur occurs if the area shifts during irradiation periods

Engineering Contradiction:

Improveimage qualityVSAvoidimage stability

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The sensor is divided into multiple sensing units that can independently detect X-rays of different energies. The filter is segmented into multiple filter units with different thicknesses or materials, each corresponding to a specific sensing unit. This segmentation allows simultaneous detection of high- and low-energy X-rays in a single irradiation, eliminating image blur caused by area shifts while maintaining image quality.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces an energy dimension by using filter units with different thicknesses or materials to separate X-rays by energy levels. Each filter unit corresponds to a specific energy range, allowing the system to capture both high- and low-energy X-ray information simultaneously in the same spatial location, thus preventing image blur while preserving image quality.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Loss of information

If multiple X-ray irradiations are performed to obtain images of different energies, then image processing can be performed, but time is lost and image blur occurs due to area shifts

Engineering Contradiction:

Improveimage information completenessVSAvoidirradiation time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The patent merges the function of multiple separate irradiations into a single irradiation event. By combining multiple filter units with different thicknesses or materials and corresponding sensing units into one integrated system, the device can capture both high- and low-energy X-ray information simultaneously during a single irradiation, eliminating time loss and preventing area shifts while maintaining complete image information.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system enables continuous detection of different energy X-rays during a single irradiation period. The multiple sensing units continuously detect high- and low-energy X-rays simultaneously without interruption or sequential switching, eliminating the time loss associated with multiple separate irradiations while maintaining complete image information.

Inventive Principle:

Principle #20Continuity of useful action

3Productivity

If filter units with different thicknesses or materials are used to separate X-rays by energy, then single irradiation image capture is enabled, but device complexity increases

Engineering Contradiction:

Improveimage capture efficiencyVSAvoidfilter and sensor structure

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The filter and sensor system is designed with multi-functionality where each filter unit corresponds to a specific sensing unit, creating a modular universal structure. This design allows the same basic structure to handle multiple energy levels simultaneously, enabling single irradiation image capture while managing device complexity through standardized modular components rather than entirely separate systems for each energy level.

Inventive Principle:

Principle #6Universality (Multi-functionality)
