Portable coffee brewing device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coffee brewing devices are non-portable and bulky, limiting the ability of coffee drinkers to enjoy freshly brewed coffee on the go, despite the development of personal coffee makers that still lack portability.
Innovation Solution
A portable coffee brewing device featuring a container with a hinge-connected lid, a heating element housing, and an electrical component housing, including a drip tube and K-cup holder, allowing for brewing a fresh cup of coffee anywhere by connecting to an external power source.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional coffee makers are designed with multiple components and internal heating elements, then brewing functionality is improved, but device portability deteriorates
Solution Approach 1:
The coffee brewing device is divided into separable components: a removable coffee grounds holding device (K-cup holder) that can be detached from the brewing chamber, allowing users to easily replace coffee pods without moving the entire device. This segmentation enables functional completeness while maintaining portability through modular design.
Solution Approach 2:
The device integrates multiple functions into a single portable unit: water heating, coffee brewing, and dispensing capabilities are combined in one device that can operate from external power sources. The brewing chamber serves multiple purposes as both a heating vessel and a dispensing mechanism, eliminating the need for separate pots and pitchers.
2Reliability
If personal coffee makers are designed for single serving, then coffee freshness is improved, but device portability remains poor
Solution Approach 1:
The coffee grounds holding device (K-cup holder) nests within the brewing chamber, with the filter and grounds container fitting inside the heating chamber. This nested arrangement allows the entire brewing system to be compact and portable while maintaining the single-serve functionality needed for fresh coffee preparation anywhere.
Solution Approach 2:
The device incorporates a movable lid and removable coffee holder that can be easily accessed and manipulated. The dynamic design allows users to quickly load fresh coffee pods and retrieve brewed coffee, maintaining convenience and portability while ensuring coffee is always fresh since only single servings are prepared.
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
Enables users to make a high-quality, fresh cup of coffee wherever desired, with an intuitive, durable, and safe design that is easy to use and clean, using K-cups, and does not leak, addressing the need for a portable coffee brewing solution.
Implementation Method 1
A heating element housing and an electrical component housing is connected to a lower end of the container... When the container is filled with fluid and the heating element is powered, heated fluid is forced up the drip tube
Implementation Method 2
A lid pivotally connected to an upper end of the container by a hinge

AI summary
A portable coffee brewing device includes a lid pivotally connected to an upper end of the container by a hinge and button. A heating element housing and an electrical component housing is connected to a lower end of the container. A drain is positioned in a bottom wall of the container and is fluidly connected to a heating element positioned within the heating element housing. The heating element is controlled by electrical components positioned in the electrical components housing. A drip tube is fluidly connected to the heating element and the lid. A single serve coffee holding device is positioned below the lid. When the container is filled with fluid and the heating element is powered, heated fluid is forced up the drip tube through the passageway in the lid and into the coffee grounds holding device in a continuous cycle. The device is connectable to an external power source.
