Inspection Device Flow Adjustment Plate for Uniform Water Film
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional moving inspection devices for metal plates face issues with increased weight due to integrated water tanks, affecting manual operability, and non-uniform water supply when water is provided from a separate source, leading to inadequate defect inspection.
Innovation Solution
A moving inspection device with a separate water supply system and a flow adjustment plate that distributes water uniformly across the metal plate surface as it moves, ensuring consistent inspection performance without the weight and size burdens of an integrated water tank.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water tank is integrated into the inspection device, then water supply is ensured, but device weight and size increase significantly
Solution Approach 1:
The system is divided into two independent parts: a stationary water supply device and a moving inspection device body. The water tank and supply mechanism are separated from the inspection device, allowing the inspection device to remain lightweight while water supply reliability is maintained through the separate supply system.
Solution Approach 2:
A flow adjustment plate is introduced as an intermediary component between the water supply device and the inspection area. This plate actively manages water distribution, ensuring uniform water film formation without requiring the inspection device to carry its own water tank.
2Weight of moving object
If water is supplied from separate source, then device weight is reduced, but water supply uniformity deteriorates
Solution Approach 1:
The flow adjustment plate serves as a mediator that actively regulates water flow from the separate supply source. It distributes water uniformly across the inspection area, creating a consistent water film thickness despite the decentralized water source, thereby maintaining manufacturing precision in terms of water supply uniformity.
Solution Approach 2:
The flow adjustment plate automatically adjusts water distribution based on local flow conditions, eliminating the need for complex manual regulation. This self-regulating mechanism ensures uniform water supply across different areas without requiring the inspection device to be heavy or complex.
3Device complexity
If manual movement of inspection device is used, then device complexity is reduced, but positioning accuracy deteriorates
Solution Approach 1:
The system replaces manual mechanical positioning with an automated control system that uses position information to guide the inspection device. This substitution maintains relatively simple device structure while significantly improving positioning accuracy through automated control based on measured position data.

AI summary
A moving inspection device capable of realizing significant size reduction/weight reduction without affecting the inspection performance for an inspection target, a moving inspection method, and a method for manufacturing a steel material. A moving inspection device includes: a moving inspection device body configured to inspect an inspection target for defects while moving over a surface of the inspection target; and water supply devices separate from the body and configured to supply water required for the inspection onto the surface of the inspection target. The body is installed with a flow adjustment plate configured to push out the water supplied onto the surface of the inspection target from the water supply devices in the advancing direction and form streamlines for supplying the water between inspection sensors configured to inspect the inspection target for defects and the surface of the inspection target simultaneously with the movement of the body.
