Single-serve coffee pods face inherent constraints in delivering consistent extraction across varying brew parameters. Current systems operate within narrow pressure bands (typically 9-15 bar) and temperature ranges (88-96°C), while consumer preferences for strength, body, and flavor notes demand wider operational flexibility. Field measurements show extraction yields varying by up to 25% between machines using identical pods.

The fundamental challenge lies in designing pod architectures that can maintain structural integrity under varying pressure conditions while enabling precise control over extraction parameters.

This page brings together solutions from recent research—including adaptive brewing chambers with variable pressure control, smart pods with embedded parameter encoding, filter designs with controlled flow resistance, and point-of-sale customization systems. These and other approaches focus on achieving repeatable extraction profiles while maintaining the convenience of single-serve brewing.

1. Brewing System with Adjustable Brewing Parameters and Pods Featuring Extendable Filter Section

Sung Oh, 2023

A brewing system that personalizes the taste of single-serve pod beverages by adjusting the brewing parameters like pressure, temperature, and time. The pod has a filter with holes and an extendable section. The brewing chamber detaches the section to create a gap for beverage flow. The brewer injects water into the pod which extracts the beverage and exits through the holes and gap. Varying hole size and grind adjusts pressure. Changing temperature and time reduces bitterness.

2. Smart Coffee Machine with Automatic Brew Pressure Adjustment Based on Detected Coffee Pack Type

LAVAZZA PROFESSIONAL NORTH AMERICA, LLC, 2022

Customizing beverages made by smart coffee machines using user devices like smartphones. The machine detects the type of coffee pack inserted and adjusts brewing pressure if necessary to match the pack's optimal brew pressure. If the pack's pressure is different from the machine's default brew pressure, the machine brews at the pack's pressure to make a modified beverage. This allows users to bring their preferred coffee packs from other sources and still get properly brewed coffee in the machine. The machine can also suggest additional beverages based on packs that become available.

3. Capsule Coffee Machine with Image-Based Identification Code Decoding for Automatic Water Volume and Temperature Adjustment

Cheng Uei Precision Industry Co., LTD., 2022

Recognition and automatic extraction method for a capsule coffee machine that automatically sets the water outputting volume and the water temperature by capturing and decoding the identification code of the coffee capsule. The method includes receiving an image of an identification code of a coffee capsule, the coffee capsule being positioned in a receiving groove of the capsule coffee machine, the camera being arranged to a portion of the capsule machine and positioned to corresponding to the receiving groove; and decoding the identification code of the coffee capsule in the image; and setting a target of a water outputting volume and a target of a water temperature according to the decoded identification code of the coffee capsule.

4. Coffee Container with Adjustable Ring-Shaped Central Chamber for Variable Coffee Capacity

SOCIETE DES PRODUITS NESTLE S.A., 2020

Coffee container for extraction in beverage preparation machines that provides optimal coffee extraction for short and long cups without needing complex machine adaptations. The coffee container has a fixed outer shape but an adjustable inner space. The container is like a donut with a ring-shaped central chamber. The size of the central chamber can be adjusted to hold more or less coffee depending on the desired cup size. This allows extracting the right amount of coffee for short or long cups from a single container shape.

5. Capsule Coffee Flavoring System with Adjustable Brewing Parameter Control and Sensor Feedback Mechanism

Jiangnan University, JIANGNAN UNIVERSITY, 2020

An adjustable parameter capsule coffee flavoring system and method for optimizing brewing parameters to improve coffee taste from capsule machines. The system has a controller that monitors and adjusts variables like water temperature, pressure, and flow rate during brewing. It uses sensors to measure parameters like water temperature and pressure, and adjusts the brewing conditions based on user input and presets. This allows customization of brewing parameters for optimal coffee flavor extraction.

6. Automated In-Store Coffee Pod Customization and Packaging Machine

Darryl Ingvard Jensen, Edward Francis Burress, Kurt Allen Jenkins, 2019

A machine for creating customized coffee pods at the point of sale. The machine grinds, fills, seals, and packages fresh coffee into K-cup style coffee pods right in the store. This allows customers to have personalized coffee blends or single-origin beans in pod format without the need for large-scale commercial packaging. The machine automates the process of grinding, filling and sealing coffee into pods to provide customized coffee pod options at the point of sale.

7. Brewing Pod with User-Fillable Filter and Piercable Lid and Base

Jerry Paige, 2018

A brewing pod that allows users to select their own brewing contents for hot beverages like coffee, tea, and hot chocolate. The pod has a cup with a filter inside to hold user selected contents like coffee grounds, tea leaves, or chocolate. A complementary lid seals the cup. The lid has an insert that can be pierced by a brewing machine nozzle. The cup bottom can also be pierced by a discharge nozzle. This allows hot water to be sprayed into the cup to brew the contents and then dispensed as a hot drink.
