Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If vibration panels generate localized vibrations for tactile representation, then tactile sensation is improved, but power consumption and heating increase
Solution Approach 1:
The base substrate is divided into multiple vibration elements with different areas, allowing selective activation of specific regions rather than vibrating the entire panel. This segmentation enables localized tactile feedback while reducing overall power consumption and heat generation.
Solution Approach 2:
Different vibration elements are designed with different areas to provide optimized tactile sensation for specific application scenarios. By tailoring the vibration characteristics of individual elements rather than using a uniform design, the system achieves better tactile feedback efficiency with lower energy consumption.
2Area of stationary object
If vibration panels are attached to large surfaces, then coverage area is improved, but tactile sensation is reduced
Solution Approach 1:
The large surface is divided into multiple independent vibration elements of different areas. This segmentation allows the system to maintain strong tactile sensation in each individual element while collectively covering a large surface area, solving the dilution of tactile feedback that occurs with uniform large-area panels.
Solution Approach 2:
Each vibration element is designed with optimized dimensions suitable for its specific location and function. Smaller elements provide focused tactile feedback in specific zones, while the collective arrangement of multiple elements achieves broad coverage without compromising the intensity of tactile sensation in any given area.
3Manufacturing precision
If annular hollow patterns with different areas are designed for each vibration element, then vibration control precision is improved, but manufacturing complexity increases
Solution Approach 1:
Each vibration element incorporates annular hollow patterns with specific area ratios optimized for its size and intended function. This local optimization of structural parameters enables precise control of vibration characteristics for each element, allowing the system to achieve superior vibration control precision through localized structural tailoring rather than uniform design.
