Solution Overview

Problem

Existing spraying booths require complex and time-consuming cleaning operations for color changes, leading to increased production time and costs due to the need for manual shutdown and extensive cleaning procedures.

Innovation Solution

A spraying booth with automated cleaning means, including a telescopic boom and suction system, that allows for systematic and rational cleaning without the need for manual intervention, reducing technical and structural complexity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual cleaning operations are used in known spraying booths, then cleaning can be performed, but the operation requires complete shutdown of machinery and increases production time and costs

Engineering Contradiction:
Improvecleaning operationVSAvoidproduction time
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The cleaning system operates autonomously without requiring manual intervention or machinery shutdown. The automated boom with cleaning devices performs cleaning tasks independently, allowing the spraying booth to maintain operational status while cleaning occurs, thus eliminating production time loss.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The cleaning system uses a mobile, vertically sliding roof structure that dynamically adjusts during operation. The roof moves to accommodate the cleaning boom's movement between retracted and extended positions, enabling cleaning operations to occur without interrupting the spraying process.

Inventive Principle:
Principle #15Dynamics

2Extent of automation

If automated cleaning means with anthropomorphic boom are installed, then cleaning automation is achieved, but the cleaning means become complex, bulky, and expensive

Engineering Contradiction:
Improvecleaning automationVSAvoidcleaning means complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The cleaning system is divided into modular components: a mobile roof structure, a telescopic boom with cleaning devices, and a suction system. This segmentation allows each component to perform its specific function independently, reducing overall system complexity while maintaining automation capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mobile roof structure serves multiple functions: it provides the sliding mechanism for the cleaning boom, houses the suction system, and maintains the booth's enclosed space. This multi-functionality reduces the need for separate dedicated components, simplifying the overall system.

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

3Adaptability or versatility

If frequent color changes are performed, then product variety is increased, but continuous cleaning and maintenance operations increase time and costs

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

Solution Approach 1:

The automated cleaning system operates continuously without interrupting the spraying process. The cleaning boom can clean surfaces during or between coating operations, eliminating idle time associated with manual cleaning shutdowns and enabling faster color changes.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The cleaning system is pre-positioned and ready to operate at all times. The mobile roof and telescopic boom are maintained in a ready state, allowing immediate cleaning operations when color changes are required, thus minimizing transition time between different powder colors.

Inventive Principle:
Principle #10Preliminary action
