Solution Overview

Problem

Existing peening apparatuses for improving surface roughness of metallic materials produced by additive manufacturing are difficult to maintain, as they often require complex and hard-to-replace components that are prone to damage from abrasive particles and high-pressure liquids.

Innovation Solution

A peening apparatus with a modular design featuring a processing tank, a table for workpieces, and a moving unit with a separable nozzle head portion that allows for easy maintenance, where the nozzle head can be detached and replaced without disassembling the entire unit, and includes a cover to suppress scattering of abrasive particles and liquids.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the nozzle head is made as a single integrated unit with the moving mechanism, then the structural strength and alignment precision are improved, but the maintenance difficulty and replacement time increase significantly

Engineering Contradiction:
Improvestructural strengthVSAvoidmaintenance difficulty
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The nozzle head is divided into a modular structure with a nozzle head body and a separately replaceable nozzle assembly. The nozzle assembly including the nozzle, connecting shaft, and spindles can be detached from the nozzle head body without disassembling the entire moving unit, enabling quick maintenance while preserving the structural integrity of the integrated moving mechanism.

Inventive Principle:
Principle #1Segmentation

2Manufacturing precision

If the nozzle head is made as a single integrated unit, then the alignment precision is improved, but the replacement time and productivity loss increase

Engineering Contradiction:
Improvealignment precisionVSAvoidreplacement time
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The nozzle assembly is designed as a pre-assembled modular unit that can be quickly replaced on the nozzle head body. This segmentation allows the alignment precision to be maintained through precise mounting interfaces while reducing replacement time, as the entire nozzle assembly can be swapped without disassembling the moving unit.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The nozzle assembly is pre-assembled with all necessary components (nozzle, connecting shaft, spindles) before installation on the nozzle head body. This preliminary assembly ensures proper alignment and reduces on-site adjustment time, thereby improving productivity during maintenance operations.

Inventive Principle:
Principle #10Preliminary action

3Strength

If complex non-separable components are used, then the structural integrity is improved, but the damage from abrasive particles and high-pressure liquids increases

Engineering Contradiction:
Improvestructural integrityVSAvoiddamage from abrasive particles
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The nozzle assembly, which is directly exposed to abrasive particles and high-pressure liquids during operation, is extracted as a separately replaceable component. This allows the consumable nozzle assembly to be protected through easy replacement, while the main nozzle head body and moving unit maintain their structural integrity and are shielded from direct damage.

Inventive Principle:
Principle #2Taking out (Extraction)
