Coffee scale
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coffee scales often have display screens that can be obstructed, leading to user errors such as spilling water or overturning containers due to the need to observe weight values while adding ingredients, affecting coffee consistency and taste.
Innovation Solution
A coffee scale design with a separate weighing mechanism and display mechanism that use magnetic attraction to position the display screen conveniently for observation, allowing users to monitor weight changes and control water flow and amount during brewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display screen is integrated on the scale plate, then the structure is simple, but the display screen is blocked and the user cannot observe the weighted value
Solution Approach 1:
The coffee scale is divided into two independent parts: a weighing mechanism and a display mechanism. The display mechanism can be positioned separately from the weighing mechanism, allowing the display screen to be placed in an unobstructed location where users can easily observe the weighted value during coffee brewing.
Solution Approach 2:
A magnetic piece is introduced as an intermediary between the weighing mechanism and display mechanism. The magnetic piece enables the display mechanism to be stably positioned at a distance from the weighing mechanism while maintaining a fixed relative position, ensuring both observability and structural simplicity.
2Ease of operation
If the display mechanism is separated from the weighing mechanism, then the display screen is easily observable, but the structure becomes more complex
Solution Approach 1:
A magnetic piece is introduced as an intermediary between the weighing mechanism and display mechanism. The magnetic piece enables the display mechanism to be stably positioned at a distance from the weighing mechanism while maintaining a fixed relative position, ensuring both observability and structural simplicity.
3Reliability
If the display screen is on the scale plate, then the device is compact, but user errors occur due to blocked display
Solution Approach 1:
The coffee scale is divided into two independent parts: a weighing mechanism and a display mechanism. The display mechanism can be positioned separately from the weighing mechanism, allowing the display screen to be placed in an unobstructed location where users can easily observe the weighted value during coffee brewing.
Solution Approach 2:

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 accurate and consistent coffee brewing by allowing users to observe weight changes and control water flow and amount without obstruction, ensuring optimal coffee taste and reducing user errors.
Implementation Method 1
The first magnetic piece and the second magnetic piece are made of magnet, or one is made of magnet and the other is made of iron or iron alloy so that the weighing mechanism and the display mechanism can be attracted together in an action of magnetic force
