Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current molds and cutters for moldable materials pose health and safety risks due to sharp blades, require separate apparatuses, increase labor and maintenance costs, and often trap material due to complex shapes and embossing patterns, making it difficult to remove molded materials.
Innovation Solution
A unitary elastic mold and cutter combination with an embossed inner surface, a stretchable sidewall, and a cutting blade that extends from the sidewall, allowing for easy release of molded material by hand stretching, eliminating the need for separate cutting tools and reducing the risk of injury.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional cutters with sharp blades are used, then cutting function is achieved, but health and safety risks increase due to punctures and lacerations
Solution Approach 1:
The patent employs a flexible silicone mold cavity with an integrated cutting blade that can be stretched and deformed. The flexible nature of the silicone material allows the cutting blade to be pushed into the moldable material without exposing users to sharp edges, as the entire assembly can be stretched to release the material safely.
Solution Approach 2:
The flexible silicone mold cavity acts as an intermediary between the user and the cutting blade. Instead of direct contact with a rigid sharp blade, the user interacts with the flexible mold cavity which contains the cutting blade, allowing the blade to perform its function while the flexible material protects the user from injury.
2Productivity
If separate cutting apparatuses are used, then cutting function is provided, but labor and maintenance costs increase
Solution Approach 1:
The patent combines the mold cavity and cutting blade into a single integrated unitary structure. The cutting blade is formed as one piece with the mold cavity, eliminating the need for separate cutting apparatuses and reducing the number of components that require maintenance and cleaning.
Solution Approach 2:
The single unitary structure serves multiple functions: it acts as both the mold cavity for shaping the material and the cutting blade for forming the final shape. This multi-functional design improves productivity by consolidating operations into one apparatus.
3Manufacturing precision
If complex perimeter shapes and embossed patterns are used, then detailed molding is achieved, but material entrapment increases making removal difficult
Solution Approach 1:
The patent utilizes the dynamic stretching capability of the flexible silicone material. When the mold cavity is stretched, the flexible walls expand and release the molded material from complex embossed patterns and perimeter shapes, allowing detailed molding while enabling easy removal through mechanical deformation.
Solution Approach 2:
The physical state of the mold cavity changes from a compressed form during molding to a stretched form during material removal. This parameter change in the mold cavity's geometry allows it to maintain detailed embossed patterns during formation while expanding to release the material easily.

AI summary
A unitary elastic mold and cutter combination configured to mold and cut moldable material is disclosed herein. The mold and cutter combination comprises an elastic mold cavity having an elastic bottom wall with an embossed inner surface and an elastic sidewall extending from and unitary with a perimeter of the bottom wall. An elastic cutting blade extends from and is unitary with the sidewall of the mold cavity and is configured to cut moldable material and maintain a substantially consistent perimeter upon cutting. The cutting blade comprises a cutting edge disposed between an inner cutting blade surface and an outer cutting blade surface. The mold and cutter combination may have an elasticity sufficient to release molded material therefrom by hand stretching, wherein the cutting edge, inner cutting blade surface, and the inner surface of the sidewall of the mold cavity are stretched by an amount sufficient to release the molded material.
