Engineering Contradiction Analysis
1Volume of moving object
If touchscreens are used to detect multiple simultaneous touches, then the flexibility and compactness are improved, but the precision and ease of operation deteriorate due to substantial motor skills requirements and imprecise control
Solution Approach 1:
The patent combines mechanical control elements with multi-touch sensing display technology into a single integrated input device. The mechanical control elements (rotary knobs, sliders, push buttons) are mounted directly on the touchscreen surface, merging the precision of mechanical control with the compactness and visual feedback of touchscreen technology. This allows the device to maintain small form factor while providing precise parameter adjustment through tactile mechanical interfaces.
Solution Approach 2:
The mechanical control elements serve as intermediaries between the user and the digital parameter adjustment system. These physical controls provide precise mechanical input that is detected by the multi-touch sensing display, translating tactile mechanical movements into accurate digital parameter changes while maintaining visual feedback on the display surface.
2Adaptability or versatility
If graphical control elements are used on touchscreen, then the adaptability is improved, but the ease of operation deteriorates due to substantial space requirements and difficulty in operating multiple elements
Solution Approach 1:
The mechanical control elements are designed to be programmable and reconfigurable, allowing a single physical control element to perform multiple functions depending on software configuration. The multi-touch sensing display detects various interaction modes (rotation direction, sliding distance, pressing force) from each mechanical element, enabling one physical control to adjust multiple parameters or perform different functions based on operational context, thereby achieving versatility without requiring multiple separate controls.
3Adaptability or versatility
If electromechanical input elements with encoders are used, then the programmability is improved, but the device complexity and cost increase significantly
Solution Approach 1:
The patent replaces complex electromechanical encoder systems with a simpler combination of basic mechanical control elements and optical/capacitive sensing. Instead of using encoders that require mechanical shafts, gears, and electronic decoding circuits, the invention uses straightforward mechanical movements (rotation, sliding, pressing) that are detected by the multi-touch sensing display's existing sensor array, eliminating the need for separate encoder hardware while maintaining programmability through software.
Solution Approach 2:
The mechanical control elements are designed to be programmable and reconfigurable, allowing a single physical control element to perform multiple functions depending on software configuration. The multi-touch sensing display detects various interaction modes (rotation direction, sliding distance, pressing force) from each mechanical element, enabling one physical control to adjust multiple parameters or perform different functions based on operational context, thereby achieving versatility without requiring multiple separate controls.
4Productivity
If multiple mechanical control elements are integrated on display surface, then the productivity is improved, but the ease of manufacture deteriorates due to mounting difficulty and space requirements
Solution Approach 1:
The mechanical control elements are mounted directly on the touchscreen display surface, merging the control interface with the display structure. This integration allows multiple control elements to be arranged in a compact grid pattern on the display surface, enabling simultaneous adjustment of multiple parameters while utilizing the existing display manufacturing process and structure, thereby improving productivity without significantly complicating the manufacturing process.
