Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional shot-blasting machines require manual loading and unloading, which is costly, labor-intensive, and space-consuming, and the integration with separate robots increases installation, control, and maintenance costs, as well as complicates operations.
Innovation Solution
An automated shot-blasting machine with integrated loading and unloading mechanisms, utilizing a centrifugal projecting system and a rotating cage with automated pusher elements to move products through a conveyor belt or roller plane, allowing for efficient and space-efficient surface treatment without the need for additional personnel or large machinery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual loading and unloading is used, then labor costs and operational complexity are reduced, but productivity and efficiency deteriorate
Solution Approach 1:
The patent combines the loading/unloading function with the shot-blasting chamber by integrating pusher organs directly into the chamber structure. These pusher organs are positioned to automatically advance products onto and off the treatment surface without requiring external robotic systems or manual intervention, thus merging two separate operations into one unified system.
Solution Approach 2:
The pusher organs are configured to automatically perform the loading and unloading operations as products pass through the chamber. The system serves itself by using the movement of products through the chamber to trigger the pusher mechanism, which then automatically positions products for treatment and removes them afterward, eliminating the need for external automation systems.
2Extent of automation
If articulated robots are used for loading and unloading, then automation is improved, but device complexity and installation costs worsen
Solution Approach 1:
The patent merges the product manipulation function directly into the shot-blasting chamber structure. The pusher organs are integrated components of the chamber rather than separate robotic systems, eliminating the need for complex articulation mechanisms, sensors, and control systems that would be required for articulated robots.
Solution Approach 2:
The patent extracts the complex robotic manipulation system and replaces it with a simplified pusher mechanism that is directly integrated into the chamber. This extraction removes the unnecessary complexity of articulated robots while retaining the essential function of automated product handling.
3Extent of automation
If articulated robots are used for loading and unloading, then automation is improved, but maintenance costs and operational expenses worsen
Solution Approach 1:
The patent employs simple pusher organs that are structurally basic and easy to manufacture, replacing expensive articulated robots. These pusher components are designed to be simple mechanical elements that can be easily fabricated, installed, and maintained, significantly reducing both initial investment and ongoing maintenance costs while performing the required automation function.
Solution Approach 2:
The pusher organs are designed to operate automatically without requiring complex control systems, sensors, or programmable logic that would increase maintenance costs. The system uses the natural movement of products through the chamber to trigger the pusher mechanism, eliminating the need for expensive automation control infrastructure.
4Adaptability or versatility
If fork-lift trucks or lifting devices are used, then product handling capability is improved, but space requirements and manoeuvring area worsen
Solution Approach 1:
The patent combines the product advancement function with the shot-blasting chamber by positioning the advancing line adjacent to the chamber and using pusher organs integrated into the chamber structure. This merging eliminates the need for separate fork-lift trucks or lifting devices that would require additional manoeuvring space, as the entire handling process occurs within or immediately adjacent to the treatment chamber.
Solution Approach 2:
The patent transitions from three-dimensional manoeuvring space required by fork-lift trucks to a two-dimensional planar advancement system. Products move along an advancing line in a single direction and are processed by pusher organs that act perpendicular to the movement direction, eliminating the need for vertical lifting and complex spatial manoeuvring.

AI summary
The shot-blasting machine for surface treatment of products comprises a base frame, a containing chamber for containing at least a product to be treated associated to the base frame and provided with at least an access opening, one or more projecting organs associated internally of the chamber for projecting a flow of shot-blasting particles onto the product, and automated unloading means associated to the base frame which cause the product to exit from the chamber through the access opening.
