Solution Overview

Problem

Existing powder coating booths require extensive manual cleaning and maintenance between color changes, leading to increased production times and costs due to the need for complete deactivation of machinery and manual operator intervention.

Innovation Solution

A coating booth with automated cleaning means, including a guide element and a blowing device with a rotatable and translatable lance, enabled by an electronic control unit, allows for efficient and automated cleaning of the compartment, minimizing operator involvement and optimizing resource use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual cleaning operations are performed between color changes, then the booth can be prepared for the next coating operation, but the production time increases and operator involvement is required

Engineering Contradiction:
Improvecolor change capabilityVSAvoidcleaning time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The booth performs cleaning operations automatically using a robotic arm with cleaning tools, eliminating the need for manual operator intervention. The system serves itself by detecting when cleaning is needed and executing the cleaning cycle autonomously, thereby reducing both cleaning time and labor requirements while maintaining adaptability for color changes.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If the booth is deactivated for manual cleaning, then operators can safely enter and clean the compartment, but production downtime increases

Engineering Contradiction:
Improvecleaning safetyVSAvoidproduction efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent replaces manual mechanical cleaning operations with an automated robotic system. The robotic arm equipped with cleaning tools enters the compartment autonomously to perform cleaning tasks, eliminating the need for operator entry and thereby maintaining production continuity while ensuring safe cleaning operations.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Reliability

If complete internal cleaning is performed, then the booth is ready for different colored powders, but the complexity and cost of maintenance increase

Engineering Contradiction:
Improvecolor change readinessVSAvoidcleaning system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The robotic arm is designed as a multi-functional device that can perform various cleaning tasks including wiping walls, cleaning the floor, and removing powder residues. This universal cleaning system handles all cleaning requirements for different color changes through a single automated platform, reducing overall system complexity while ensuring complete cleaning readiness.

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