Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing shot blasting devices require frequent changes of jigs when processing different types of workpieces, leading to increased processing time and inefficiency.
Innovation Solution
A shot processing device with an autorotation mechanism and a hanger unit that allows for the projection of shot media onto a workpiece without the need for jig changes, using a loading/unloading device to handle trays with workpieces, enabling efficient processing of various types without exchanging jigs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a jig matched to the product shape is used to process without surface irregularity, then processing quality is improved, but processing time increases due to frequent jig exchanges when product types vary
Solution Approach 1:
The hanger unit is designed with a universal structure that can accommodate multiple types of workpieces without requiring jig exchanges. The frame sections and connecting sections form a standardized configuration that can adapt to different product shapes and sizes, allowing the same hanger unit to serve multiple functions for various workpiece types.
Solution Approach 2:
The hanger unit incorporates movable and adjustable components, including the pair of frame sections that can be positioned and configured dynamically. The connecting sections allow for flexible arrangement of the frame sections to match different workpiece geometries, enabling the system to adapt its configuration rather than requiring static, dedicated jigs for each product type.
2Manufacturing precision
If jigs are exchanged when product types are varied to maintain processing quality, then manufacturing precision is preserved, but productivity decreases due to repeated setup time
Solution Approach 1:
The hanger unit serves as a universal fixture that can process multiple types of workpieces through its standardized frame sections and connecting sections. This multi-functionality eliminates the need for dedicated jigs for each product type, allowing continuous processing without setup interruptions and thereby maintaining both quality and productivity.
Solution Approach 2:
The hanger unit is pre-configured with adjustable frame sections and connecting sections that can be positioned to accommodate different workpiece types. This preliminary preparation of the universal structure allows for quick adaptation to new product types without time-consuming jig exchanges, as the basic framework is already in place and ready for configuration.
3Reliability
If a fixed jig structure is used to ensure stable processing, then reliability is improved, but adaptability decreases when handling various types of workpieces
Solution Approach 1:
The hanger unit employs dynamic, adjustable components including the pair of frame sections that can be repositioned and the connecting sections that allow flexible configuration. This dynamic structure maintains processing stability through controlled adjustability rather than fixed rigidity, enabling reliable processing of diverse workpiece types without sacrificing adaptability.
Solution Approach 2:
The hanger unit is divided into modular frame sections connected by connecting sections, allowing independent adjustment and configuration of each segment. This segmentation enables the structure to adapt to different workpiece geometries while maintaining overall stability, as each module can be optimized for its specific function while contributing to the whole system's reliability.

AI summary
A hanging section is installed at an upper side of a cabinet, and an autorotation mechanism rotates the hanging section around an axis of the hanging section in upward/downward directions of a device. In addition, a hanger unit hanging from the hanging section is installed in a cabinet, and a pair of frame sections is parallelly installed in series to match opening directions. Then, projection machines project a shot media toward the hanger unit. In addition, a loading/unloading device installed outside the cabinet is configured such that arm constituting a part thereof can be inserted into an opening section of the frame section of the hanger unit, and a tray on which a workpiece is placed can be conveyed. The loading/unloading device loads/unloads the tray with respect to the hanger unit by advancing and retracting the arm.
