Solution Overview

Problem

Conventional shot treatment devices have complex structures due to the need for detector protection panels and mechanisms, which hinder efficient cycle time management and prevent simultaneous processing of multiple workpieces.

Innovation Solution

A shot treatment device with a rotary table and multiple chambers allows for simultaneous loading, unloading, and inspection of workpieces, with inspection detectors capable of ascending and descending in separate chambers, and a blower for dust removal, simplifying the structure and enhancing processing efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If an inspection detector is built in the treatment chamber, then inspection can be performed during shot peening, but the structure inside the treatment chamber becomes complex due to detector protection panels and mechanisms

Engineering Contradiction:
Improvecycle timeVSAvoidstructure inside treatment chamber
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The device is divided into multiple independent chambers (shot peening chamber, first inspection chamber, second inspection chamber, loading chamber, unloading chamber) arranged around the rotary table. Each chamber has a specific function, allowing inspection processes to be separated from the shot peening process. This segmentation eliminates the need for complex detector protection mechanisms within the shot peening chamber while maintaining continuous production capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inspection detector is extracted from the shot peening chamber and placed in a separate first inspection chamber. This extraction removes the detector and its protection mechanisms from the shot peening environment, simplifying the shot peening chamber structure while enabling continuous inspection through the rotary table's multi-chamber configuration.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If a detector protection panel and pivot mechanism are provided, then the inspection detector is protected during shot peening, but the structure inside the treatment chamber becomes more complex

Engineering Contradiction:
Improvedetector protectionVSAvoidstructure inside treatment chamber
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The inspection function is segmented into separate chambers (first inspection chamber and second inspection chamber) distinct from the shot peening chamber. This spatial segmentation eliminates the need for detector protection panels and pivot mechanisms within the shot peening chamber, as detectors are positioned in dedicated inspection chambers where they operate in a controlled environment away from shot media.

Inventive Principle:
Principle #1Segmentation

3Productivity

If multiple workpieces are to be processed simultaneously, then cycle time is reduced, but the treatment chamber structure becomes more complex

Engineering Contradiction:
Improvesimultaneous processing capabilityVSAvoidtreatment chamber structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The treatment device is segmented into multiple chambers (shot peening chamber, first inspection chamber, second inspection chamber, loading chamber, unloading chamber) arranged around the rotary table. Each chamber handles a specific stage of the workpiece processing cycle, enabling multiple workpieces to be at different stages of processing simultaneously. This segmentation achieves parallel processing without requiring complex internal structures within any single chamber.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rotary table serves as a universal platform that supports multiple placement tables, each capable of holding a workpiece. The rotary table enables continuous movement of workpieces through different chambers, providing multi-functionality that supports simultaneous loading, shot peening, inspection, and unloading operations without requiring separate dedicated structures for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)
