Solution Overview

Problem

Existing methods for applying particulates to molded products with three-dimensional designs often distort the original shape, requiring a secondary impressing operation that is undesirable, especially for food products like cookies or pet treats.

Innovation Solution

A rotary molding apparatus that integrates a dough hopper and a particulate hopper, where particulates are introduced into molds with three-dimensional designs before being filled with dough, ensuring the particulates are embedded without distorting the design, using a continuous looping belt system to extract and process the molded products.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If particulates are sprinkled over the surface of molded products and then impressed into the surface, then the particulates are successfully applied to the product surface, but the three-dimensional design on the surface is distorted and an additional secondary operation is required

Engineering Contradiction:
Improvethree-dimensional design integrityVSAvoidproduction efficiency
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent applies particulates to the mold cavity surfaces before the molding process begins. The particulates are introduced into the mold cavities and distributed on the surfaces, then the mold is filled with material in a single continuous operation, eliminating the need for subsequent impressing operations and preserving the three-dimensional design integrity

Inventive Principle:
Principle #10Preliminary action

2Ease of manufacture

If a secondary impressing operation is used to embed particulates into the product surface, then particulate application is achieved, but the process becomes more complex and time-consuming

Engineering Contradiction:
Improveprocess simplicityVSAvoidcycle time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The patent combines the particulate application step with the molding operation into a single integrated process. Both operations are performed simultaneously within the mold cavity, eliminating the need for separate impressing equipment and operations, thereby simplifying the manufacturing process and reducing cycle time

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The invention provides molded products having particulates and a method and device for applying particulates to the surface of the molded products. In a general aspect, the molded product comprises an undistorted three-dimensional design and has particulates that do not distort the shape of the three-dimensional design. The molded product can be made by a method comprising filling a mold in a die roll with one or more particulates, filling the mold with a dough, compressing the dough into the mold, and releasing the compressed dough from the mold to form the molded product.
