Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional collimators are used to limit the X-ray beam, then the beam profile can be changed to line or rectangular shape, but the beam cannot be accurately centered and the width cannot be adjusted, leading to beam deflection and scattering

Engineering Contradiction:
Improvebeam centering accuracyVSAvoidbeam width adjustment convenience
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The collimator is divided into multiple independent adjustable components (first and second collimators with separate adjusting screws) that can be individually positioned to precisely control different aspects of the beam profile and centering

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The collimator components are made adjustable through threaded screws and sliding mechanisms, allowing dynamic modification of beam width and centering position to optimize inspection quality for different applications

Inventive Principle:
Principle #15Dynamics

2Reliability

If the thickness of the ray shielding layer is increased to reduce beam deflection and scattering, then inspection quality improves, but the device complexity and size increase

Engineering Contradiction:
Improveinspection qualityVSAvoidshielding layer thickness
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The collimators are positioned to pre-align and precisely center the beam before it enters the shielding layer, ensuring optimal beam geometry is established upfront so that thinner shielding can effectively control scattering and deflection

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If the beam profile is fixed by conventional collimators, then the beam shape is limited, but the ability to adjust beam width and angle is lost

Engineering Contradiction:
Improvebeam profile adjustment capabilityVSAvoidbeam width control accuracy
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The collimator system incorporates multiple adjusting screws (first and second adjusting screws on each collimator) that enable dynamic adjustment of beam width in different directions and beam angle, allowing the same apparatus to adapt to various inspection requirements while maintaining precise control

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The collimator assembly can produce multiple beam profiles (line shape, rectangular shape, fan shape) by adjusting the position of the collimator components, making the apparatus versatile for different inspection applications without requiring multiple fixed collimators

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