Heated Roller Butter Spreader for Fast Even Application
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for spreading butter or margarine on bread or toast are time-consuming, especially in a restaurant setting, and require large quantities of butter, making them inefficient for melting and even application.
Innovation Solution
A roller spreading device comprising a base member and a roller member, where the base member is designed to hold and melt the butter, and the roller member rotates within the base member to efficiently spread the melted butter over food products, minimizing the amount of butter needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a knife is used to manually spread butter, then the butter can be applied to bread or toast, but the process is time-consuming and lengthens food preparation time
Solution Approach 1:
The patent replaces the manual knife-spreading mechanism with a heated roller mechanism that automatically spreads butter. The roller is heated to melt the butter and then rolls it evenly across the bread surface, eliminating the manual spreading action and significantly reducing preparation time.
Solution Approach 2:
The butter is pre-heated and melted in the base member before the spreading action occurs. This preliminary melting prepares the butter in an optimal state for spreading, allowing the roller to distribute it evenly and quickly without the need for manual softening or cutting.
2Manufacturing precision
If butter is melted before spreading, then it spreads evenly over the food surface, but it becomes difficult to control and requires large quantities to operate prior art devices
Solution Approach 1:
The roller mechanism provides dynamic control over the butter spreading process. The roller can be pressed with varying pressure and rolled across the bread surface in a controlled manner, allowing precise distribution of melted butter. This dynamic control enables even spreading while using minimal butter quantities.
Solution Approach 2:
The heated roller applies heat locally to the butter and bread surface during the spreading action. This localized heating ensures the butter remains in an optimal melting state only where needed, allowing for precise control and minimal waste. The roller transfers butter from the base member to the bread in a controlled, localized manner.

AI summary
A roller spreading device for spreading a butter substance over a food product is provided. The device includes a basin structure and a roller member. The basin structure is sized to hold the butter substance for melting therein, the basin structure including a lower floor surface extending with an arcuate structure. The roller member includes a cylindrical outer surface with multiple recesses therein sized to capture the butter substance along the multiple recesses. The roller member, suspended within the basin structure, rotates about an axis such that the roller member rotates through the butter substance pooled along the arcuate structure.
