Pour-Over Brewer Nozzle and Filter Motion for Consistent Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pour-over brewing techniques for coffee and tea are inefficient and inconsistent due to manual, labor-intensive processes, leading to variations in beverage quality and safety concerns for baristas, including ergonomic and burn hazards.
Innovation Solution
A beverage brewing apparatus with a movable filter holder and nozzle that allows controlled movement and fluid flow rate, temperature, and timing to optimize the brewing process, reducing labor and improving consistency and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual pour-over brewing is used, then beverage customization and artistic presentation are improved, but labor intensity and inconsistency increase
Solution Approach 1:
The patent implements a movable nozzle that can dynamically adjust its position and movement pattern over the filter holder. This allows the system to automate the pour-over brewing process while maintaining the ability to create different flow patterns and customize beverage preparation, thereby reducing labor intensity without sacrificing operational flexibility or consistency
Solution Approach 2:
The apparatus enables self-service automated brewing by programing the nozzle to automatically move and dispense water according to predetermined patterns. The system can autonomously complete the brewing process without manual intervention, significantly reducing labor intensity while maintaining consistent beverage quality
2Adaptability or versatility
If manual pour-over brewing is used, then beverage customization is improved, but consistency and quality control deteriorate
Solution Approach 1:
The patent incorporates sensors and control systems that monitor the brewing process in real-time, tracking parameters such as water flow rate, temperature, and nozzle position. This feedback mechanism ensures consistent execution of brewing patterns while allowing for programmable customization, thereby maintaining both adaptability and reliability
Solution Approach 2:
The movable nozzle system can be programmed with precise movement patterns and flow rates, allowing the same customized brewing recipe to be reproduced consistently. The dynamic positioning capability ensures that each pour-over brewing follows the same controlled path, eliminating variability while maintaining customization options
3Ease of operation
If manual pour-over brewing is used, then artistic presentation is improved, but safety concerns for baristas increase
Solution Approach 1:
The automated apparatus performs the entire pour-over brewing process without human intervention, eliminating the need for baristas to handle hot water and equipment. The system autonomously creates the artistic flow patterns while keeping operators at a safe distance, thereby maintaining presentation quality without exposing personnel to burn hazards or ergonomic risks
Solution Approach 2:
The patent introduces an automated nozzle system as an intermediary between the water source and the filter holder. This intermediary device handles all interactions with hot water and brewing components, shielding baristas from direct exposure to harmful factors while still enabling controlled artistic presentation through programmable movement patterns

AI summary
Shown is an apparatus for brewing a beverage, such as coffee, as well as associated methods for brewing a beverage. Apparatuses and methods are included to reduce labor involved in pour-over brewing techniques, while providing greater consistency in the results. Manual and/or automatic movements are provided to a filter (e.g., rotation) and/or a nozzle dispensing liquid over the filter. Water dosage and timing therefore can be automated to the filter. The nozzle can be positioned off-center with respect to the filter to ensure wetting thereof. The nozzle can be made movable for constrained changes to the path of liquid flow relative to the rotating filter.
