Solution Overview

Problem

Conventional cleaning systems in canteen kitchens face challenges in adapting to varying loads and types of soiling, leading to inefficient personnel planning and machine utilization, resulting in overcapacity and increased costs.

Innovation Solution

A cleaning device equipped with a sensor system and a slide mechanism that automatically identifies and redirects specific items, such as trays, transversely to a receiving device, allowing for flexible operation and efficient sorting and stacking, while other items continue through the system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If cleaning equipment and personnel planning are designed to handle peak loads, then the system can cope with maximum demand, but staff utilization is insufficient during low-demand periods and costs increase

Engineering Contradiction:
Improveability to handle peak loadsVSAvoidstaff utilization efficiency
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The conveyor belt system dynamically adjusts its operation by selectively pushing out specific items (trays) transversely during the cleaning process. This dynamic sorting mechanism allows the system to adapt to varying load types and volumes without requiring additional personnel or equipment capacity, thereby maintaining reliability during peak loads while improving staff utilization during lower-demand periods

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The automatic sensor-based detection and mechanical pushing system performs sorting and removal functions without human intervention. The system autonomously identifies trays needing removal and executes the pushing action, replacing manual labor with automated functionality that operates consistently across all demand levels, thus eliminating the need to over-dimension staff resources

Inventive Principle:
Principle #25Self-service

2Adaptability or versatility

If manual sorting and removal of items is performed, then flexibility in handling different item types is achieved, but productivity decreases and labor costs increase

Engineering Contradiction:
Improveflexibility in handling different item typesVSAvoidcleaning system throughput
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent replaces manual mechanical sorting with an automated sensor-detection and mechanical pushing system. Sensors automatically detect tray positions and types, triggering the pushing mechanism to remove specific items without human intervention. This substitution maintains the flexibility to handle different item types while dramatically increasing productivity and reducing labor requirements

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

Solution Approach 2:

The pushing mechanism acts as an intermediary between the conveyor belt and the removal point, selectively transferring specific items (trays) from the main conveyor to a removal position. This intermediary mechanism enables automated sorting functionality that preserves adaptability to different item types while eliminating the need for manual handling

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If the conveyor belt transports all items continuously, then throughput is maximized, but the ability to selectively remove specific items (trays) is reduced

Engineering Contradiction:
Improveconveyor throughputVSAvoidselective item removal capability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The conveyor system is segmented into functional zones: a detection zone where sensors identify trays, a pushing zone where mechanical actuators remove selected trays transversely, and a continuation zone where remaining items proceed on the main conveyor. This segmentation allows the system to maintain continuous throughput while selectively removing specific items without disrupting the overall flow of other items

Inventive Principle:
Principle #1Segmentation
