Solution Overview
Problem
Conventional coffee brewing devices are not portable, making it difficult for individuals to brew coffee on the go, and existing personal coffee makers lack the portability and convenience needed for easy use and transportation.
Innovation Solution
A portable coffee brewing device with a hinge-connected lid, a heating element housing, and an electrical component housing, featuring a drip tube and a single-serve coffee holding device, allowing for brewing anywhere with a K-cup and minimal power consumption, and incorporating a recirculating fluid system for efficient brewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional coffee makers are designed with multiple components and heating elements, then coffee brewing functionality is improved, but device portability deteriorates
Solution Approach 1:
The patent combines multiple functional components (heating element, water reservoir, coffee grounds holder, and brewing chamber) into a single integrated portable device. The housing contains all necessary components for brewing coffee, eliminating the need for separate appliances and making the device portable while maintaining full brewing functionality.
Solution Approach 2:
The portable coffee maker is designed to perform multiple functions within a single device: heating water, holding coffee grounds, brewing coffee, and providing insulation. This multi-functionality allows the device to replace multiple separate appliances while remaining portable.
2Ease of operation
If personal coffee makers are designed for single serving, then ease of use is improved, but portability deteriorates
Solution Approach 1:
The device is divided into distinct functional segments: a removable coffee grounds holder, a water reservoir, a heating element housing, and an insulated brewing chamber. This segmentation allows for easy cleaning and maintenance while maintaining overall device portability through compact integration.
3Reliability
If coffee makers include multiple components, then brewing quality is improved, but device complexity increases
Solution Approach 1:
Multiple brewing components are merged into a compact integrated housing that contains the heating element, water reservoir, coffee grounds holder, and brewing chamber. This integration maintains all necessary components for quality brewing while reducing overall device complexity and improving portability.
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 device provides a convenient, portable, and efficient means to brew high-quality coffee using K-cups with minimal power, ensuring a fresh cup whenever needed, while being easy to use and clean, and designed for durability and ergonomic handling.
Implementation Method 1
an internal heating element which is connected to a source of electricity
Implementation Method 2
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

AI summary
A portable coffee brewing system includes a top housing containing a pump and a tube. Portable coffee brewing system also includes a basket housing having a punch operatively connected to the top housing and having a receiving member; the basket housing having a receiving member configured to receive a basket. The basket being capable of holding a coffee grounds holding device which is capable of holding coffee grounds. A nozzle is attached to the lower part of the basket to create an opening for fluid to flow through. The system providing a user with a means of brewing coffee by inserting a coffee grounds holding device into a basket. A punch within the basket punctures the coffee grounds holding device; the basket then being operably connected to the rest of the system so fluid can move through the system when the system is activated to brew coffee or other beverages.
