Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing haptic feedback modules face issues with uneven vibration feedback due to single vibration sources and increased manufacturing costs with multiple vibration sources.
Innovation Solution
A haptic feedback module design that uses a single vibration component to transmit vibration energy via a vibration-transmitting point array on a vibration-transmitting plate, indirectly contacting the member to be vibrated, providing uniform vibration feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single vibration source is directly attached to the member to be vibrated, then the manufacturing cost is reduced, but the vibration feedback becomes uneven
Solution Approach 1:
The patent introduces a vibration-transmitting plate as an intermediary component between the single vibration source and the member to be vibrated. This plate distributes the vibration energy from the single vibration source to multiple vibration-transmitting points on the member, achieving uniform vibration feedback without requiring multiple vibration sources. The intermediary structure resolves the contradiction by enabling both cost-effectiveness (single vibration source) and performance (uniform vibration distribution).
2Manufacturing precision
If multiple vibration sources are distributed to provide uniform vibration feedback, then the vibration uniformity is improved, but the manufacturing cost increases
Solution Approach 1:
The patent segments the vibration transmission function by creating multiple vibration-transmitting points on the member to be vibrated. Instead of using multiple vibration sources, the single vibration source's energy is divided and transmitted through multiple contact points on the member, achieving uniform vibration distribution. This segmentation approach maintains manufacturing simplicity while improving vibration uniformity.
3Device complexity
If a single vibration source is used, then the device complexity is reduced, but the vibration energy distribution becomes uneven
Solution Approach 1:
The vibration-transmitting plate serves as a mediator that redistributes vibration energy from the single vibration source to multiple points on the member. This intermediary structure enables even energy distribution without increasing device complexity or the number of vibration sources, resolving the contradiction between simplicity and performance.

AI summary
A haptic feedback module is applied to a haptic feedback operation of a device and includes a member to be vibrated, a vibration-transmitting plate, a vibration-transmitting point array, and a vibration component. The member to be vibrated is disposed on the device. The vibration-transmitting plate has an upper vibration-transmitting surface and a lower vibration-transmitting surface opposite to each other. The vibration-transmitting point array is disposed on the upper vibration-transmitting surface and contacts the member to be vibrated. The vibration component is disposed on one of the upper vibration-transmitting surface and the lower vibration-transmitting surface and coupled to the device. When the haptic feedback operation is performed, a vibration energy from the vibration component driven by the device passes through the vibration-transmitting plate and the vibration-transmitting point array sequentially to the member to be vibrated, for providing a haptic feedback to the device.
