Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If rotary electromechanical switches or rotary encoders are used for controlling beverage parameters, then the control panel allows selection and setting of multiple parameters, but mechanical wear and dirt accumulation occur leading to failures
Solution Approach 1:
The patent replaces rotary electromechanical switches and rotary encoders with a capacitive touch-sensitive display. The touch-sensitive display detects finger touches and gestures through capacitive sensing, eliminating all rotating or moving mechanical parts. This substitution maintains ease of operation through intuitive touch interfaces while completely preventing mechanical wear and dirt accumulation that caused reliability issues.
Solution Approach 2:
The patent extracts and removes the rotating or moving parts from the control panel system. By eliminating rotary knobs, electromechanical switches, and moving components entirely, the design prevents the mechanical wear and oxidation problems that affected reliability, while maintaining full control functionality through the touch-sensitive interface.
2Adaptability or versatility
If multiple rotating or moving parts are included in the control panel, then various functions can be controlled, but the complexity of mechanical components increases leading to more failures
Solution Approach 1:
The capacitive touch-sensitive display serves multiple functions that previously required separate mechanical components. A single touch interface handles beverage selection, parameter adjustment, temperature control, and other functions, eliminating the need for multiple rotary switches and encoders. This reduces structural complexity while maintaining or enhancing versatility.
Solution Approach 2:
The patent merges multiple control functions into a single integrated touch-sensitive display interface. Instead of having separate rotary knobs and switches for different functions, all control operations are unified in one electronic interface, simplifying the overall structure while preserving full functionality.
