Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibration generation apparatuses for touch panels lack the ability to appropriately decide on the timing of vibration provision, failing to effectively provide tactile feedback to users during operation.
Innovation Solution
A tactile sense provision apparatus comprising a transparent plate, an actuator, and a control unit that receives signals from the touch panel operation to vibrate the transparent plate, providing tactile feedback to the user through vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a vibration generation apparatus is used to provide tactile feedback through the entire electronic equipment, then the user can perceive the sense of operation through vibrations, but the timings when vibrations are to be provided cannot be appropriately decided
Solution Approach 1:
The invention divides the vibration feedback system into localized segments by placing multiple actuators at different positions on the touch panel, allowing independent control of vibration timing and location for different touch events, thus resolving the timing precision issue while maintaining tactile feedback effectiveness
Solution Approach 2:
The control unit receives operation signals from the touch panel and automatically triggers corresponding actuators at precisely determined timings based on the touch event data, creating a closed-loop feedback system that ensures appropriate vibration timing without manual intervention
2Device complexity
If a touch panel is operated without tactile feedback, then the device structure remains simple, but the user cannot perceive the acceptance of operations
Solution Approach 1:
The invention introduces actuators as intermediary components between the touch panel and the user's finger, converting electrical operation signals into mechanical vibrations that provide tactile feedback, thereby transmitting operation acceptance information without significantly complicating the overall device structure
Solution Approach 2:
The invention replaces traditional mechanical keyboard structures with a touch panel combined with electronic actuators, achieving tactile feedback through electromagnetic-to-mechanical energy conversion rather than through complex mechanical linkages, thus maintaining structural simplicity while providing operation feedback
