Friction activated ground coffee dosing dispenser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coffee dispensers face challenges in efficiently dispensing pre-ground coffee due to clumping, which hinders smooth flow and leads to mess and incomplete usage, especially when filling reusable pods or espresso portafilters.
Innovation Solution
A friction-activated coffee ground dispenser with a conically-tapered reservoir and rotating or sliding mechanism that applies frictional forces to break up clumps and ensure smooth flow into a pre-measured amount in a reusable pod or filter, utilizing agitating members and adjustable dispensing reservoirs for precise dosing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ground coffee is stored in a reservoir for later dispensing, then convenience is improved, but the granulated nature of the grounds causes clumping and prevents smooth flow
Solution Approach 1:
The dispenser employs a vibratory mechanism that generates mechanical vibrations to agitate the ground coffee in the reservoir, breaking up clumps and promoting smooth flow of grounds during dispensing operations
Solution Approach 2:
The system changes the physical state of the ground coffee by applying vibrational energy, transforming the static, clumped grounds into a dynamically flowing state that can be reliably dispensed
2Productivity
If a scoop is used to transfer ground coffee, then transfer is possible, but the shape of the scoop and container causes grounds to get stuck and not all grounds are used
Solution Approach 1:
The dispenser extracts the ground coffee directly from the reservoir through a dispensing opening, eliminating the need for intermediate transfer tools like scoops that cause grounds to get stuck between surfaces
Solution Approach 2:
A vibratory intermediary mechanism is introduced between the reservoir and dispensing opening to facilitate the movement of grounds, ensuring complete transfer without manual scooping
3Ease of operation
If ground coffee is dispensed manually, then control over dispensing is possible, but it leads to mess and difficulty in getting precise measurements
Solution Approach 1:
The dispenser is designed to perform the dosing operation automatically through vibratory activation, allowing the system to serve itself by controlling the flow of grounds without requiring manual intervention that creates mess
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 convenient, mess-free dispensing of pre-measured coffee grounds, ensuring all grounds are used without getting stuck in containers, and is adaptable for various brewing applications.
Implementation Method 1
The frictional forces on the ground coffee generated by gravity and the rotation of the rotary dispenser during a transition from the first rotated state to the second rotated state activates the coffee grounds and causes the coffee grounds to flow down the tapered reservoir into the dispenser reservoir.
Implementation Method 2
The frictional forces on the ground coffee generated by gravity and the rotation of the rotary dispenser during a transition from the first rotated state to the second rotated state activates the coffee grounds and causes the coffee grounds to flow down the tapered reservoir into the dispenser reservoir.
