Advanced drip filter coffee maker
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drip filter coffee machines face difficulties in removing the filter basket due to the presence of the showerhead and have cleaning challenges, and using pour-over type filters can be cumbersome.
Innovation Solution
A drip filter coffee machine design featuring a filter basket with a spring-biased lid and latch mechanism, along with a hinged lid that supports a water dispenser, allowing for easy removal and cleaning, and incorporating a fluid coupling system for efficient water flow and a damping mechanism to resist lid opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a showerhead is fixed to the main body above the filter basket, then water dispensing function is achieved, but the filter basket becomes difficult to remove
Solution Approach 1:
The filter basket is divided into separate components: a removable basket portion and a lid portion. The lid can be opened independently to provide access for cleaning the showerhead while the basket remains in place, and the entire basket assembly can be removed when needed.
Solution Approach 2:
The showerhead is extracted from the main body and integrated into the lid of the filter basket. This allows the showerhead to move with the lid, providing clear access to the showerhead for cleaning purposes and enabling easy removal of the basket portion.
2Ease of operation
If a showerhead is fixed to the main body, then water dispensing is enabled, but cleaning the showerhead becomes difficult
Solution Approach 1:
The showerhead is extracted from the fixed mounting on the main body and relocated to the lid of the filter basket. This extraction provides clear access to the showerhead for cleaning, as the lid can be opened to expose the showerhead completely.
Solution Approach 2:
The showerhead is made dynamic by attaching it to the movable lid rather than fixing it to the stationary main body. The lid can be opened to any angle, allowing flexible access positions for cleaning the showerhead from multiple angles.
3Ease of operation
If a hinged lid with spring bias is used, then lid opening is assisted, but lid opening resistance is needed for controlled movement
Solution Approach 1:
Different forces are applied at different stages of lid opening. The spring provides assisting force at the beginning of opening to overcome the latch, while the damping mechanism provides resistance during the opening motion to control the speed and prevent slamming.
Solution Approach 2:
The force characteristics are asymmetric: the spring force assists opening (positive force), while the damping force resists opening (negative force). This creates a balanced system where the lid opens easily but in a controlled manner.
4Ease of operation
If fluid coupling halves are used for filter basket removal, then engagement and disengagement is facilitated, but fluid connection reliability must be maintained
Solution Approach 1:
The fluid coupling is segmented into two separate halves: one attached to the main body and one attached to the filter basket. This segmentation allows the basket to be easily engaged and disengaged, while the coupling surfaces are designed to maintain reliable fluid connections when engaged.
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 design enhances user convenience by facilitating easy filter basket removal and cleaning, improves brewing flexibility with pour-over capabilities, and ensures efficient water distribution through the fluid coupling and damping mechanisms.
Implementation Method 1
The lid is biased into an open position by a spring
Implementation Method 2
An opening of the lid into the open position is resisted by a damping mechanism
