Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional vibration feedback structures are used, then the device structure is simple, but the tactile feedback precision is insufficient and vibration feeling is single
Solution Approach 1:
The vibration feedback device is segmented into functionally independent modules: a button module for input, a sensor module for detection, and a vibration motor module for feedback output. This segmentation allows each module to be optimized independently, improving tactile feedback precision while maintaining manageable overall complexity
Solution Approach 2:
The patent introduces a perpendicular dimension between the button pressing direction and the antenna vibration direction. The button presses vertically while the antenna vibrates horizontally, creating a two-dimensional feedback mechanism that enhances tactile precision without requiring complex multi-axis actuation systems
2Adaptability or versatility
If the button pressing direction is parallel to the antenna vibration direction, then the structure is simple, but the vibration feeling becomes single and less diverse
Solution Approach 1:
The patent employs asymmetric orientation between the button pressing direction (vertical) and the antenna vibration direction (horizontal). This asymmetric configuration creates diverse vibration sensations by decoupling the input and output directions, allowing rich tactile feedback without requiring symmetric multi-directional actuation mechanisms
Solution Approach 2:
By transitioning from a one-dimensional parallel arrangement to a two-dimensional perpendicular arrangement between button pressing and antenna vibration, the system achieves diverse vibration feelings. The elastic connection member enables this dimensional transition, allowing the antenna to vibrate perpendicular to the button press direction

AI summary
A vibration feedback device, a handheld communication device including the same and a wearable device. The vibration feedback device is provided on a frame and includes a button fixed to the frame; a sensor for detecting a pressing state of the button; and a vibration motor fixed to the frame and arranged below the button. The frame includes an outer side surface, an inner side surface, and a mounting hole penetrating through the outer and inner side surfaces; the vibration motor includes a stator fixed to the inner side surface, an antenna arranged in the mounting hole, and an elastic connection member connecting the antenna to the stator; and a direction of a pressing force of the button is perpendicular to a vibrating direction of the antenna. The vibration feedback device provides a vibration feedback that is different from the direction of the pressing force and is diversified.
