Solution Overview

Problem

Existing food preparation tables with fixed frame catchment systems are inconvenient to manufacture, use, and clean due to their rigid design, which hinders table production and maintenance.

Innovation Solution

A modular grate and catch pan assembly with removable frame units, grates, and pans that are easily cleaned and maintained, featuring retaining pins and lip structures for secure positioning and easy removal, allowing for independent cleaning of each component without disassembling the entire system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed frame catchment system is used, then the structure is stable and secure, but the system is difficult to manufacture, clean, and maintain

Engineering Contradiction:
Improvestructural stabilityVSAvoidmanufacturing convenience
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The fixed frame catchment system is divided into separate modular components: individual frame units, grates, and catch pans that can be independently manufactured, assembled, and cleaned. Each component is standardized with consistent dimensions and attachment mechanisms, enabling simplified production while maintaining structural integrity when assembled.

Inventive Principle:
Principle #1Segmentation

2Reliability

If a fixed frame catchment system is used, then the structure is stable, but the system is difficult to clean and maintain

Engineering Contradiction:
Improvestructural stabilityVSAvoidcleaning convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The catchment system is segmented into removable components (frame units, grates, and catch pans) that can be easily detached and cleaned separately. This modular design allows each component to be accessed and cleaned independently without disassembling the entire structure, significantly improving maintenance convenience while preserving structural stability during operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from a completely fixed structure to a dynamically configurable assembly where components can be easily attached and detached. The retaining mechanisms (pins, clips, or snap-fits) enable quick assembly and disassembly, allowing the structure to be stable during use but flexible during cleaning and maintenance operations.

Inventive Principle:
Principle #15Dynamics

3Ease of manufacture

If a modular grate and catch pan arrangement is used, then manufacturing efficiency and cleaning convenience are improved, but the structural stability may be reduced

Engineering Contradiction:
Improvemanufacturing efficiencyVSAvoidstructural stability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The system is divided into standardized modular components that can be manufactured independently using consistent processes and materials. Each frame unit, grate, and catch pan is designed with uniform attachment interfaces that ensure reliable assembly while simplifying manufacturing. The modular design allows for quality control of individual components and efficient assembly line production.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple functional components (frame structure, grate, and catch pan) are combined into integrated assembly units that maintain structural stability when assembled. The retaining mechanisms securely connect components to each other, creating a stable configuration during food preparation while allowing easy disassembly for cleaning and maintenance.

Inventive Principle:
Principle #5Merging (Combining)
