Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing X-ray inspection devices face challenges in distinguishing between foreign objects like dust and components from the assembly line, leading to inefficiencies in production lines as they often require stopping the production line for inspection, which reduces efficiency.
Innovation Solution
An X-ray inspection device with a plurality of determination standards, utilizing an X-ray detecting unit, determining unit, and output unit, sets first and second thresholds to differentiate between foreign objects and components, allowing for real-time sorting and minimizing production line interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single threshold is used to detect foreign objects, then the detection process is simple, but it cannot distinguish between dust and components leading to unnecessary production line stoppages
Solution Approach 1:
The patent divides the detection system into multiple determination units, each responsible for specific foreign object types (dust, components, etc.). Each unit has its own threshold and determination logic, allowing differentiated handling of different foreign object categories while maintaining overall system manageability
Solution Approach 2:
Different thresholds and determination criteria are assigned to different foreign object types based on their specific characteristics. Dust detection uses one set of criteria while component detection uses another, optimizing detection accuracy for each category without requiring a single complex universal threshold
2Reliability
If the production line stops for every foreign object detection, then all foreign objects can be inspected, but production efficiency is reduced
Solution Approach 1:
The determination units dynamically select appropriate actions based on foreign object type and severity. For dust particles, the system may allow continued production with monitoring, while for critical components, it triggers production line stoppage. This dynamic response optimization balances inspection completeness with production efficiency
Solution Approach 2:
The system changes the response parameter (production line status) based on the detected foreign object type. Different thresholds and determination criteria lead to different operational states - either continued production or production stoppage - optimizing the balance between reliability and productivity
3Measurement precision
If multiple determination standards are implemented, then foreign object classification improves, but the device complexity increases
Solution Approach 1:
The determination system is segmented into multiple independent determination units, each handling specific foreign object types. This modular structure improves classification accuracy while keeping each unit's complexity manageable and allowing independent optimization of each determination module
