Radiation Pulse Scheduling for Adaptive Object Inspection

Solution Overview

Problem

Existing inspection systems face challenges with adaptability, as they are either poorly adaptable to different objects due to single ray sources or have higher costs and weights due to the use of multiple ray sources.

Innovation Solution

An inspection system that includes a radiation source, a detector, and a processor to determine and select periodic radiation combinations based on the object's type and mode, allowing for the emission of radiation with varying energies to different portions of the object, optimizing energy usage and adaptability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single specific ray source is used in the inspection system, then the device complexity is reduced, but the adaptability to different types of inspected objects deteriorates

Engineering Contradiction:

Improvedevice complexityVSAvoidadaptability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic switching between different ray energy modes (first mode with lower energy, second mode with higher energy) based on the inspection requirements. The system can dynamically adjust the ray source characteristics during operation to match different inspected objects, resolving the contradiction between fixed device complexity and variable adaptability requirements.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the energy parameter of the ray source by switching between different operational modes. The first mode uses lower ray energy for objects requiring reduced radiation exposure, while the second mode uses higher ray energy for thicker or denser objects, allowing a single device to adapt to multiple inspection scenarios without increasing physical complexity.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If two different ray sources are used in the inspection system, then the adaptability to different inspected objects is improved, but the device complexity and cost increase

Engineering Contradiction:

ImproveadaptabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent makes a single ray source perform multiple functions by enabling it to operate in different energy modes. The same ray source can serve both low-energy inspection requirements (first mode) and high-energy inspection requirements (second mode), eliminating the need for separate ray sources while maintaining full adaptability across different object types.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the functionality of multiple ray sources with different energy levels into a single unified ray source system. By merging the capabilities of what would traditionally require separate devices into one system with switchable modes, the patent achieves full adaptability while reducing overall device complexity and cost.

Inventive Principle:

Principle #5Merging (Combining)
