Solution Overview

Problem

Existing rotary molding systems for food patty formation face challenges in efficient maintenance and product flow, leading to increased downtime and costs due to complex and expensive components like the fill plate, which requires costly replacement and maintenance.

Innovation Solution

The rotary molding system incorporates a stripper plate capable of reciprocal movement relative to a wear plate, with retainer bars allowing easy removal for maintenance, and a cylindrical drum with mold cavities, along with a platen and rollers for efficient food product distribution and air management, reducing wear and maintenance costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the fill plate is used as a fixed component with multiple holes for food product flow, then the structural integrity and product flow are maintained, but the maintenance cost and downtime increase due to wear and damage

Engineering Contradiction:
Improvestructural integrityVSAvoidmaintenance cost and downtime
Core Design Contradiction:
ReliabilityVSEase of repair

Solution Approach 1:

The fill plate is divided into a stationary wear plate and a movable stripper plate that can be independently removed and replaced. This segmentation allows the stripper plate to be easily swapped during maintenance without replacing the entire fill plate assembly, reducing downtime and maintenance costs while maintaining structural integrity through the stationary wear plate

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The stripper plate is designed as a replaceable, relatively inexpensive component that can be easily swapped when worn or damaged. This allows the system to use a low-cost, short-living component (stripper plate) that can be quickly replaced rather than replacing the entire expensive fill plate assembly, thereby reducing maintenance costs and downtime

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Stability of the object's composition

If the stripper plate is fixed in position, then the structural stability is maintained, but the maintenance complexity and downtime increase

Engineering Contradiction:
Improvestructural stabilityVSAvoidmaintenance complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The stripper plate is designed with dynamic capability to move reciprocally relative to the wear plate during operation, and can be easily removed from retainer bars when maintenance is needed. This dynamic design allows the component to be stable during operation but easily accessible for maintenance, reducing maintenance complexity and downtime while preserving structural stability during the molding process

Inventive Principle:
Principle #15Dynamics

3Device complexity

If the drum rotates directly without rollers, then the structure is simpler, but the motor amperage required increases

Engineering Contradiction:
Improvestructural simplicityVSAvoidmotor amperage
Core Design Contradiction:
Device complexityVSUse of energy by moving object

Solution Approach 1:

Rollers are introduced as intermediary elements between the drum and the platen, allowing the drum to rotate with reduced friction. The rollers act as mediators that transfer motion while reducing the direct contact friction, thereby decreasing the motor amperage required for drum rotation while maintaining a relatively simple overall structure

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A rotary molding system for use in a patty forming machine and configured to mold food products and a fill plate for use within the rotary molding system are provided. A replaceable wear plate is provided which seats between a reciprocating stripper plate and a fill plate. Each plate has holes through which food product passes. A drum having mold cavities receives the food product from the fill plate.
