Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vibration actuator is installed in the user interface to transmit vibrations, then haptic feedback function is added, but vibration transmission efficiency is insufficient
Solution Approach 1:
The device is divided into two separate structures: a first structure containing the vibration actuator and first supporting body, and a second structure containing the touch panel module and second supporting body. This segmentation allows the vibration actuator to be isolated from the touch panel's rigid structure, preventing energy loss while maintaining haptic feedback functionality.
Solution Approach 2:
A vibration damping member is introduced as an intermediary component between the first supporting body and the second supporting body. This damping member acts as a mediator that transmits vibrations efficiently while isolating the touch panel module from direct mechanical coupling, thereby improving vibration transmission efficiency without compromising the haptic feedback function.

Function Achieved in This Case
This configuration allows for efficient vibration transmission to the touch panel module, enhancing tactile feedback while minimizing the impact of the touch panel's rigidity, thus improving overall vibration efficiency.
Implementation Method 1
A linear vibration actuator 10 is provided with a magnet 13 through which a shaft 12 passes within a thin rectangular parallelepiped case 11. Springs 14 and 15 are respectively provided at left and right ends of the shaft 12 to movably hold the magnet 13 substantially at the center of the shaft 12. A coil 16 is fixed to face the magnet 13 within the case 11. By applying alternating current to the coil 16, the magnet 13 serving as a weight linearly reciprocates back and forth in the longitudinal direction of the case 11 along the shaft 12 to vibrate the case 11.
Implementation Method 2
a vibration damping member (130) that connects the first supporting body (113) and the second supporting body (121)
