Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual blasting operation is performed by hand, then flexibility and adaptability are maintained, but overall working time increases and worker health is damaged due to long exposure to harmful dust and strong spraying of abrasives
Solution Approach 1:
The blasting apparatus is designed to perform blasting operations autonomously without requiring manual operation. The automated system moves along the processed product and sprays abrasives independently, eliminating the need for workers to be directly exposed to harmful dust and abrasives while maintaining high productivity
Solution Approach 2:
The patent replaces the manual mechanical blasting operation with an automated mechanical system. The automated blasting apparatus uses mechanical conveyance mechanisms to move along the processed product and mechanically sprays abrasives, substituting human labor with automated machinery to reduce exposure time and improve productivity
2Productivity
If automated conveying devices are added to reciprocate the main body, then productivity increases and working time decreases, but device complexity increases
Solution Approach 1:
The conveying device is divided into multiple independent components including a main body conveying mechanism and a spraying device conveying mechanism. Each component can move independently along rails, allowing for modular design that improves productivity while managing complexity through functional segmentation
Solution Approach 2:
The patent employs dynamic conveying mechanisms that can reciprocate along rails to move the main body and spraying device. This dynamic design allows the system to adapt to different processing lengths and speeds, improving productivity while the modular dynamic components help manage overall system complexity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus significantly reduces overall working time and minimizes health risks by automating the blasting process, ensuring faster surface treatment of large products while maintaining stability and preventing accidents.
Implementation Method 1
the wheels of the first conveying device are configured to contact an upper surface of the first rail and to perform rolling motion; and first guide rollers configured to contact a side or lower surface of the first rail and to perform rolling motion
Implementation Method 2
blasting is a washing method of removing foreign matter (e.g., rust, oil, coating films, scale, etc.) remaining on the surface of steel by strongly spraying water containing an abrasive having a relatively high hardness, such as sand, iron powder, grit, silica particles, or a combustible material, using compressed air or other means

AI summary
The present invention relates to a mobile blasting apparatus for injecting abrasives onto the surface of an article to be processed, the mobile blasting apparatus comprising: a body; a frame structure including a first rail extending along a first direction; a first moving device which can move the position of the body reciprocally along the first rail; and an injection device coupled to the body so as to inject the abrasives. According to the present invention, all processes can be automated without workers' manual work, so that the overall working time is reduced even when an article to be processed is large in length or volume, and there is no concern that work over a long time, strong jets of abrasives, and noxious dust would cause harm to worker health.
