Solution Overview
Problem
Existing beverage and foodstuff preparation machines have user interfaces that are unsightly, expensive, occupy too much space, become unhygienic and difficult to clean, and lack user engagement.
Innovation Solution
A contactless sensor-based user interface that allows users to adjust parameters without physical contact, using proximity, movement, or gesture sensing, and provides feedback through visual or audio indicators, making the interface more hygienic, compact, cost-effective, easy to clean, and engaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional mechanical user interfaces (buttons, dials, switches) are used, then parameter adjustment functionality is achieved, but the interface becomes unsightly, expensive, occupies large space, and difficult to clean
Solution Approach 1:
The patent replaces mechanical user interface components (buttons, dials, switches) with a capacitive touch-sensitive surface that detects changes in electrical capacitance caused by proximity or contact of conductive objects (like coins or keys). This substitution eliminates mechanical wear, reduces cleaning requirements, and allows for a sleeker, more integrated design while maintaining full parameter adjustment functionality.
Solution Approach 2:
The invention creates a functional copy of traditional mechanical interface behavior through electrical field detection. Instead of physical button presses, the system detects the presence and position of conductive objects near or on the touch-sensitive surface, replicating the input functionality without the physical complexity of mechanical components.
2Ease of operation
If traditional mechanical user interfaces are used, then parameter control is enabled, but the interface becomes unhygienic and difficult to clean with repetitive use
Solution Approach 1:
By replacing mechanical buttons and switches with a capacitive touch-sensitive surface, the patent eliminates crevices, gaps, and moving parts that trap dirt and bacteria. The smooth, sealed surface can be easily wiped clean, making it hygienic for repetitive use in commercial environments while maintaining full operational capability.
3Ease of operation
If traditional mechanical user interfaces are used, then user input is received, but the interface is expensive to produce and occupies large space
Solution Approach 1:
The patent merges multiple traditional interface components into a single integrated capacitive touch-sensitive surface. Instead of separate buttons, dials, and switches occupying different spaces, all input functions are consolidated into one flat, sealed surface that detects conductive objects, reducing both component count and overall space requirements.
Solution Approach 2:
The capacitive touch-sensitive surface serves multiple functions simultaneously: it detects proximity of conductive objects, determines their position, identifies different objects based on capacitance characteristics, and provides tactile feedback through vibration. This multi-functionality replaces what would traditionally require multiple separate components.
