Food Topping Dispenser Roller Wiper Stripping Brush
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food topping dispensers fail to provide a consistent and controlled dispensing of food toppings like flour or powdered sugar, requiring multiple components and increasing production and maintenance costs.
Innovation Solution
A food topping dispenser with a hopper and an application roller that uses a wiper element and stripping brush to manage the flow and distribution of food toppings without the need for an agitator, ensuring consistent and accurate dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an agitator is used to dispense food topping, then the dispensing consistency is improved, but the device complexity and maintenance cost increase
Solution Approach 1:
The patent removes the agitator component entirely from the food topping dispensing system. Instead of using mechanical agitation to control flow, the design relies on gravity-fed flow through a hopper and controlled release through a dispensing opening, eliminating the complexity and maintenance requirements of the agitator while maintaining dispensing consistency
Solution Approach 2:
The patent replaces the mechanical agitator system with a gravity-based flow control system. The food topping flows naturally under gravity from the hopper through the dispensing opening, and the release rate is controlled by the geometry of the dispensing opening and the flow properties of the topping itself, rather than mechanical agitation
2Manufacturing precision
If multiple components are used in the dispenser, then the dispensing control is improved, but the production cost increases
Solution Approach 1:
The patent combines multiple functions into fewer components. The hopper serves both as the storage container and the flow control mechanism, while the dispensing opening geometry controls the release rate. The wiper element serves dual purposes of preventing clogging and controlling flow consistency, eliminating the need for separate agitation and control mechanisms
Solution Approach 2:
The hopper is designed to perform multiple functions: storing food topping, controlling its flow rate, and preventing clogging. The dispensing opening geometry is designed to simultaneously control flow rate and prevent bridging of the material, reducing the need for additional specialized components
3Ease of manufacture
If a simple hopper design is used, then the manufacturing cost is reduced, but the dispensing accuracy deteriorates
Solution Approach 1:
The patent applies local quality by designing the dispensing opening with specific geometric characteristics at the critical release point. The opening has controlled dimensions and shape that are optimized for accurate dispensing, while the rest of the hopper maintains a simple, easy-to-manufacture design. This localized precision at the dispensing interface achieves accurate control without requiring complex manufacturing throughout the entire structure
Solution Approach 2:
The patent controls dispensing accuracy by adjusting geometric parameters of the dispensing opening (size, shape, orientation) and the hopper configuration rather than using complex mechanical control systems. By changing these geometric parameters, accurate dispensing is achieved through simple, easily manufactured structures
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for efficient, consistent, and cost-effective dispensing of food toppings with reduced manufacturing and maintenance costs, eliminating the need for internal agitators and minimizing waste.
Implementation Method 1
A wiper element is mounted on the lower end of the back wall outside the open unobstructed interior and the discharge opening, and is continuously positioned above the application roller for engagement with the food topping received from the discharge opening upon the application roller. A stripping brush element is mounted on a lower end of the front wall outside the open unobstructed interior and the discharge opening for engagement with the exterior surface of the application roller for removing food topping retained therein.

AI summary
A food topping dispenser includes a hopper having a pair of sidewalls, a back wall and a front wall defining an open unobstructed interior sized to receive a supply of food topping. An application roller is positioned in a discharge opening of the hopper and is rotatably mounted in and between the sidewalls. The application roller has an exterior surface configured to receive and retain the food topping from the discharge opening. A wiper element is mounted on a lower end of the back wall outside the open interior in the discharge opening, and is positioned above the application roller for engagement with the food topping received from the discharge opening. A stripping brush element is mounted on a lower end of the front wall outside the open interior in the discharge opening for engagement with the exterior surface of the application roller for removing food topping retained therein.
