Solution Overview
Problem
Existing vibration mechanisms in electronic devices cannot provide precise tactile feedback to a user's trigger press.
Innovation Solution
A force feedback apparatus with a trigger, first and second transmission assemblies, and a driving assembly, which allows for precise tactile feedback through mechanisms like damping, force release, vibration, and rebound by transmitting power between the trigger and the driving assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a vibration mechanism is arranged in the electronic device to enhance physical touch, then the user can obtain tactile feedback, but the vibration mechanism can only drive the entire electronic device to vibrate and cannot provide precise tactile feedback to a trigger pressed by a user
Solution Approach 1:
The patent divides the vibration mechanism into two independent parts: a main vibration mechanism for overall device vibration and an auxiliary vibration mechanism integrated into the trigger for localized tactile feedback. This segmentation allows each component to perform its specific function independently, achieving precise trigger feedback without requiring the entire device to vibrate, thus resolving the contradiction between feedback precision and structural complexity.
2Ease of operation
If the vibration mechanism drives the entire electronic device to vibrate, then the user can obtain tactile feedback, but the tactile feedback cannot be precisely delivered to the trigger pressed by the user
Solution Approach 1:
The patent applies local quality by positioning an auxiliary vibration mechanism specifically at the trigger location, allowing tactile feedback to be delivered precisely where the user interacts with the device. This localized approach ensures that trigger press feedback is accurate and distinct from general device vibration, improving both ease of operation and feedback accuracy simultaneously.

AI summary
A force feedback apparatus is provided. The force feedback apparatus includes a base, a trigger, a first transmission assembly, and a second transmission assembly. The trigger is rotatably connected to the base. The first transmission assembly is in a transmission-connection to the trigger. The second transmission assembly includes a first gear, a transmission gear, a ring gear, and a rotatable support. The transmission gear is meshed between the first gear and the ring gear. The ring gear is fixed to the base. The rotatable support is connected to the transmission gear. The rotatable support is rotatable relative to the first gear and the ring gear. The driving assembly can drive the second transmission end to rotate.
