Tactile Panel Guider Layout for Controlled Lateral Displacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tactile presentation devices for touch panels are prone to damage due to weak structural support, which affects their operational strength and durability.
Innovation Solution
A tactile presentation device with a movable part supported by a base and a guider, where the guider regulates the displacement direction of the movable part, and one or more actuators displace the movable part in a predetermined axial direction, ensuring efficient vibration and enhanced structural support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If actuators are connected to the left and right ends of the front panel and supported by the housing at the left and right ends, then the tactile presentation device can achieve displacement control, but the structural strength becomes weak and the device may be damaged
Solution Approach 1:
The patent introduces a guider as an intermediary component between the actuator and the movable part. The guider includes a shaft and bearings that guide the movement direction, while the actuator is positioned at one end of the movable part rather than at both ends. This intermediary structure provides proper support and direction control without compromising structural strength.
2Adaptability or versatility
If actuators are positioned at left and right spaces of the housing, then the device can provide tactile feedback, but the structural integrity is compromised
Solution Approach 1:
The patent segments the support function from the actuation function. The guider (shaft and bearings) handles the support and guidance function, while the actuator focuses solely on providing tactile feedback through controlled displacement. This segmentation allows the actuator to be positioned optimally for tactile feedback without compromising structural integrity through the guider's support structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively enhances the strength and durability of tactile presentations by converting actuator force into efficient displacement in the desired axial direction, while restraining unwanted movements and noise.
Implementation Method 1
a guider that connects the base and the movable part, and regulates a displacement direction of the movable part in the one axial direction by sliding in the one axial direction

AI summary
A tactile presentation device includes a movable part, a base, a guider, and one or more actuators. The movable part includes a first main surface and presents tactile to a user by being displaced in a predetermined one axial direction parallel to the first main surface. The base supports the movable part in a displaceable manner. The guider connects the base and the movable part, and regulates a displacement direction of the movable part in the one axial direction by sliding in the one axial direction. The actuator displaces the movable part in the one axial direction from one end side of the movable part in the one axial direction. When the number of actuators is one, the actuator is located on a symmetry axis of the movable part parallel to the one axial direction.
