Problem

Existing dishwashing systems face challenges in achieving high throughput, cost efficiency, and flexibility in handling varying cleaning situations, often requiring manual interventions and being inflexible due to specific tailoring to place settings.

Innovation Solution

A modular system for loading a conveyor dishwasher comprising a detection module, interchangeable handling modules, a feed unit, and a control module that evaluates item status data to selectively feed items to appropriate handling modules based on their usability, ensuring efficient and adaptable cleaning operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a single dishwasher with multiple lanes is used, then throughput is improved, but device complexity increases

Engineering Contradiction:
ImprovethroughputVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The system is divided into multiple independent handling modules, each responsible for a specific task (removing obstructing items, food scraps, napkins, drinking glasses, cutlery, or other crockery). These modules can be selectively activated based on the detected item composition, avoiding the need for a fully complex multi-lane dishwasher while maintaining high throughput through targeted parallel processing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The handling modules are designed with universal interfaces that allow them to be reversibly coupled to and decoupled from the system. A single modular unit can perform multiple functions depending on which sub-modules are attached, replacing the need for dedicated single-function devices and reducing overall system complexity.

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

2Productivity

If dishwashers are specifically tailored to place settings, then cleaning efficiency is improved, but adaptability deteriorates

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidadaptability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adapts its configuration by selectively coupling and decoupling handling modules based on the detected item composition. The control module receives data about the items to be cleaned and activates only the necessary handling modules, allowing the system to optimize for specific cleaning scenarios while maintaining versatility across different place settings.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes its operational parameters by selecting different combinations of handling modules based on the detected item types. This allows the same physical infrastructure to be optimized for different cleaning scenarios (e.g., glass-heavy vs. cutlery-heavy placements) without requiring physical reconfiguration or dedicated equipment for each scenario.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If manual interventions are used, then flexibility is improved, but productivity deteriorates

Engineering Contradiction:
ImproveflexibilityVSAvoidproductivity
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The handling modules operate autonomously based on automated detection and control. The detection module identifies items to be cleaned, the control module processes this information and determines which handling modules are needed, and the system automatically activates the appropriate modules without requiring manual intervention. This maintains flexibility through automated decision-making while significantly improving productivity through continuous operation.

Inventive Principle:
Principle #25Self-service

4Adaptability or versatility

If multiple separate dishwashers are used, then adaptability is improved, but device complexity increases

Engineering Contradiction:
ImproveadaptabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Multiple handling modules are merged into a single integrated system that shares common infrastructure (detection module, control module, feed unit, conveyor device). This consolidation provides the adaptability of multiple specialized devices while reducing overall complexity by eliminating redundant components and simplifying the system architecture.

Inventive Principle:
Principle #5Merging (Combining)
