Hand-held brewing and extracting pipe for coffee and tea
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for brewing coffee and tea require substantial equipment and access to a stove or kettle for boiling water, limiting convenience and portability.
Innovation Solution
A hand-held brewing and extracting pipe with a metal vessel and straw, using a butane blue flame lighter or candle for heating, allowing for rapid temperature achievement without a stove, featuring a filter to separate liquids from solids and an insulating piece for safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional brewing equipment (stove, kettle, French press) is used, then brewing functionality is achieved, but portability and convenience deteriorate due to substantial equipment requirements
Solution Approach 1:
The brewing system is divided into separate functional components: a handheld pipe body, a removable filter assembly, and an external heat source (butane lighter). This segmentation allows each component to be optimized independently and enables portable, on-demand brewing without requiring a complete traditional brewing setup.
Solution Approach 2:
The pipe body serves multiple functions: it acts as both the brewing vessel and the extraction chamber, while also serving as the handling tool. The butane lighter provides both heating function and portability, replacing the need for separate stove and kettle.
2Productivity
If rapid heating to 180°C is achieved in under 2 minutes, then brewing efficiency improves, but energy consumption and safety risks worsen
Solution Approach 1:
The metal pipe body acts as an intermediary heat transfer medium between the butane flame and the water/coffee mixture. The metal's high thermal conductivity enables rapid heating while the pipe's contained structure directs and controls the flame's energy, preventing uncontrolled combustion and improving safety.
Solution Approach 2:
The system changes the heating parameters by using a high-flame-butterfly butane lighter that concentrates thermal energy delivery. This allows the water to reach 180°C rapidly (in under 2 minutes) by intensifying the heat flux, while the controlled nature of the butane flame maintains safety.
3Use of energy by moving object
If metal vessel and straw are used for heat conduction, then heat transfer efficiency improves, but user safety worsens due to burn risks
Solution Approach 1:
The insulating piece creates a thermal barrier that equalizes the temperature difference between the heated metal pipe and the user's hand. By introducing this intermediate insulating layer, the system maintains efficient heat transfer to the beverage while protecting the user from burn risks during handling.
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 quick and portable brewing of coffee or tea to the desired temperature without a stove, ensuring efficient heat transfer and safe handling, allowing for a 'shot' of beverage in under 2 minutes.
Implementation Method 1
heat is applied using a butane blue flame lighter or candle until the liquid is heated to the desired temperature
Implementation Method 2
A filter 16 is placed in the bottom of the vessel 4... the filter 16 is a micro-filter which permits the passage of liquid into the straw 6 but prevents any coffee granules 28 from passing through
Implementation Method 3
The vessel 4 must be made of a metal which has a high heat conductivity... The straw 6, also made of metal
Implementation Method 4
An insulating piece 12 may be used to enable the user to hold the pipe 2 without getting burned
