Solution Overview

Problem

Conventional mobile inspection systems lack the ability to perform local scans and have inflexible shielding structures, limiting their versatility and scanning resolution.

Innovation Solution

A mobile inspection system with a rotatable detector beam and a detachable ray shielding member, featuring a U-shaped first shielding member and plate-shaped second shielding members, allows for adjustable shielding and enhanced scanning capabilities, including a scan angle range of 85-95 degrees, and operates in multiple inspection modes for varying scanning needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the detector beam is made rotatable to enable local scanning, then the scanning resolution and versatility are improved, but the device complexity and structural stability worsen

Engineering Contradiction:
Improvescanning resolutionVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The detector beam is divided into two segments: a horizontal portion and an upright portion that can rotate independently around an upright axis. This segmentation allows the upright portion to be rotated for local scanning while the horizontal portion remains stationary, enabling high-resolution local scanning without requiring the entire detector system to move, thus managing device complexity while improving measurement precision.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The upright detector beam portion is made dynamically rotatable around the upright axis within a scan angle range of 85-95 degrees, allowing the system to switch between stationary full-scene inspection and rotated local high-resolution scanning modes. This dynamic capability improves scanning resolution when needed while maintaining structural stability during standard operation.

Inventive Principle:
Principle #15Dynamics

2Reliability

If a fixed shielding structure is used, then the radiation protection is reliable, but the adaptability to different inspection scenarios deteriorates

Engineering Contradiction:
Improveradiation protectionVSAvoidadaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The ray shielding member is made rotatable and detachable, allowing it to be rotated to different positions and detached when not needed. This dynamic design enables the shielding structure to adapt to different inspection scenarios (such as when the detector beam is rotated) while maintaining reliable radiation protection when the shielding member is in position, thus improving adaptability without compromising reliability.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The shielding system is segmented into a detachable ray shielding member that can be separated from the detector beam structure. This allows the shielding member to be independently positioned, rotated, or removed based on inspection requirements, providing flexibility for different scenarios while maintaining radiation protection when needed.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If the ray shielding member is made detachable to improve adaptability, then the versatility for different shielding structures is improved, but the structural complexity and potential radiation leakage risks worsen

Engineering Contradiction:
Improveshielding structure adaptabilityVSAvoidshielding structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The ray shielding member is designed to be detachably connected to the upright detector beam portion, allowing it to be attached when radiation shielding is needed and detached when not needed. This dynamic attachment/detachment capability provides versatility for different shielding requirements while keeping the structure relatively simple through straightforward connection and disconnection mechanisms.

Inventive Principle:
Principle #15Dynamics
