Solution Overview

Problem

Existing drying modules for containers, especially in the beverage industry, face contamination issues due to moisture accumulation, leading to frequent manual cleaning that is time-consuming and inconvenient, resulting in extended intervals between cleanings and increased germ growth.

Innovation Solution

An automated cleaning device with a closed system, using a combination of chemical and mechanical cleaning agents, including nozzles and brushes, controlled by a module that ensures regular and efficient cleaning of the drying chamber, preventing germ accumulation and contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual cleaning is performed regularly, then hygiene conditions are maintained, but production downtime increases and operator exposure to germs increases

Engineering Contradiction:
Improvehygiene conditionsVSAvoidproduction downtime
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The drying module performs cleaning automatically without human intervention. The cleaning device is integrated into the drying module and executes cleaning cycles autonomously, allowing the system to clean itself while maintaining production continuity and reducing operator exposure to contaminated environments.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The cleaning operation is performed automatically during transitions between production batches or at predetermined intervals without requiring production shutdown. This preliminary automated cleaning ensures hygiene maintenance while minimizing impact on production schedules.

Inventive Principle:
Principle #10Preliminary action

2Object-affected harmful factors

If manual cleaning frequency is increased, then germ accumulation is reduced, but time consumption and operational inconvenience increase

Engineering Contradiction:
Improvegerm accumulationVSAvoidcleaning time
Core Design Contradiction:
Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The manual mechanical cleaning process is replaced with an automated cleaning device that uses spray nozzles, brushes, and heating elements. This substitution eliminates the need for operators to physically clean the drying module, significantly reducing time consumption while maintaining or improving cleaning effectiveness.

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

Solution Approach 2:

A cleaning agent is introduced as an intermediary substance to facilitate the cleaning process. The cleaning device sprays cleaning agents onto contaminated surfaces, allowing chemical action to remove germs and dirt without requiring extensive manual labor or time.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If cleaning intervals are extended, then production efficiency is maintained, but germ load for operators increases

Engineering Contradiction:
Improveproduction efficiencyVSAvoidgerm load
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The drying module performs periodic self-cleaning automatically during production operations or transitions. This autonomous cleaning capability allows extended intervals between cleaning operations without increasing germ load, as the system maintains hygiene conditions continuously through automated interventions.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The cleaning device operates periodically at optimized intervals determined by production requirements and hygiene standards. This periodic automated cleaning maintains low germ loads while minimizing disruption to production efficiency, as cleaning occurs automatically without requiring manual intervention or extended shutdowns.

Inventive Principle:
Principle #19Periodic action
