Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In X-ray inspection devices, condensation can occur on the X-ray detection unit due to insufficient cooling, leading to potential malfunctions when the cooling unit fails, and this moisture can cause further damage.
Innovation Solution
The device includes a monitoring unit to detect anomalies in the cooling unit, stopping the flow of air to the X-ray detection unit and optionally halting X-ray irradiation and conveyance, thereby preventing condensation and maintaining operational safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the cooling unit continuously supplies cool air to the X-ray detection unit, then the detection unit is kept at a low temperature, but when the cooling unit malfunctions, condensation occurs on the detection unit
Solution Approach 1:
The monitoring unit detects anomalies in the cooling unit before condensation can occur on the X-ray detection unit. When an anomaly is detected, the control unit proactively stops the flow of air to the detection unit, preventing the harmful condensation effect before it manifests.
Solution Approach 2:
The monitoring unit continuously monitors the state of the cooling unit and provides feedback to the control unit. This feedback mechanism enables the system to detect cooling unit anomalies and respond by adjusting the air flow to the X-ray detection unit, thereby preventing condensation.
2Object-affected harmful factors
If the flow of air to the X-ray detection unit is stopped when cooling anomaly is detected, then condensation is prevented, but the detection unit may overheat
Solution Approach 1:
The system stops the air flow to the X-ray detection unit only after detecting a cooling unit anomaly, before condensation can occur. This preliminary action prevents the harmful condensation effect while the system can subsequently manage the temperature through other means or alert operators.
3Temperature
If the X-ray irradiation and detection are stopped when cooling anomaly is detected, then overheating is prevented, but productivity decreases
Solution Approach 1:
The system stops X-ray irradiation and detection only after detecting a cooling unit anomaly and determining that temperature management is compromised. This preliminary action prevents overheating while minimizing the impact on productivity by only stopping operations when truly necessary.
4Productivity
If the conveyor continues operation when cooling anomaly is detected, then productivity is maintained, but articles may be left uninspected
Solution Approach 1:
The system continues conveyor operation only after determining that the X-ray detection unit has reached a safe temperature or that the anomaly is non-critical. This preliminary assessment maintains productivity while ensuring inspection completeness by only continuing operations when safe to do so.
