Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If current X-ray tomography equipment is designed for uniformly shaped small samples, then sample changing throughput is high, but flexibility and adaptability to various part geometries deteriorates

Engineering Contradiction:
Improvesample changing throughputVSAvoidflexibility to part geometries
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The sample stage is segmented into multiple chambers (first chamber, second chamber, third chamber) that can independently hold different samples. This segmentation allows the system to maintain high throughput by processing multiple samples simultaneously while adapting to various part geometries through the modular chamber design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sample stage is designed with universal mounting features including clamps, fixtures, and support structures that can accommodate uniformly shaped small samples as well as larger parts with wide variety of physical shapes. The mounting arm with adjustable positioning provides multi-functional capability to handle different sample types.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Extent of automation

If X-ray tomography equipment is used during second and third shift hours with reduced staff availability, then automated operation is required, but sample changing capacity and flexibility deteriorates

Engineering Contradiction:
Improveautomated operation capabilityVSAvoidsample changing capacity
Core Design Contradiction:
Extent of automationVSAdaptability or versatility

Solution Approach 1:

Multiple samples are pre-loaded into the first chamber, second chamber, and third chamber of the sample stage before automated operation begins. This preliminary action enables the automated system to continuously process samples without requiring staff intervention for sample changing, maintaining both automation extent and sample changing capacity.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The sample stage with multiple chambers is nested within the existing tomography equipment's sample manipulator receiver. This nesting approach allows the enhanced sample stage to integrate with the automated existing system, maintaining automation capability while increasing sample changing capacity through the multi-chamber design.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Productivity

If X-ray tomography equipment is designed for physically small uniformly shaped geometry parts, then scanning efficiency is high, but ability to accommodate larger parts with wide variety of physical shapes deteriorates

Engineering Contradiction:
Improvescanning efficiencyVSAvoidaccommodation of various part sizes and shapes
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The mounting arm incorporates dynamic positioning capabilities with adjustable slots and mounting features that can be reconfigured for different sample sizes and geometries. This dynamic adaptability allows the system to maintain scanning efficiency by optimizing positioning for each sample type while accommodating larger parts with wide variety of physical shapes.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Different chambers and mounting features are designed with local quality variations - some areas optimized for small uniformly shaped parts with precise positioning, while other areas accommodate larger parts with different geometries. This local specialization maintains scanning efficiency for each sample type while providing overall versatility.

Inventive Principle:
Principle #3Local quality

4Quantity of substance

If sample stage has multiple chambers for vertical stacking, then sample capacity increases, but device complexity deteriorates

Engineering Contradiction:
Improvesample capacityVSAvoidsample stage structure
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The sample stage is divided into multiple independent chambers (first chamber, second chamber, third chamber) that can be manufactured and assembled as separate modules. This segmentation increases sample capacity while managing device complexity through modular design, allowing each chamber to be optimized independently and assembled into the complete sample stage.

Inventive Principle:
Principle #1Segmentation
