Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If conventional vibration methods are used in display apparatuses, then the structure remains simple, but the intensity of ultrasonic vibration and haptic feedback is insufficient
Solution Approach 1:
The vibration apparatus is divided into multiple vibration transfer parts (first, second, third vibration transfer parts) with distinct functions. The first vibration transfer part converts in-plane vibration to out-of-plane vibration, the second transfers vibration from the third part to the display member, and the third generates the initial vibration. This segmentation allows each part to be optimized for its specific function, achieving intense ultrasonic vibration while maintaining manageable structural complexity.
Solution Approach 2:
The patent employs dimensionality change by converting in-plane vibration (parallel to the display member surface) into out-of-plane vibration (perpendicular to the surface) through the first vibration transfer part. This dimensional transformation is crucial for generating effective ultrasonic haptic feedback, as out-of-plane vibration modes are necessary for stimulating tactile receptors and providing realistic texture recognition.
2Ease of operation
If in-plane vibration mode is used, then the vibration generation is straightforward, but the tactile feedback and texture recognition are insufficient
Solution Approach 1:
The first vibration transfer part is specifically designed to convert in-plane vibration from the third vibration transfer part into out-of-plane vibration that can be transmitted to the display member. This dimensional conversion enables effective tactile feedback and texture recognition by creating vibration modes that stimulate human tactile receptors, while the overall system maintains ease of operation through the systematic arrangement of vibration transfer components.
