Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional gamepads have a poor user experience due to their trigger structure, which relies on springs for reset elastic force and only considers pressing force, failing to provide a rich and immersive experience.
Innovation Solution
A trigger driving apparatus with a bracket and a movable trigger housing, featuring a drive device connected to a link rod mechanism, a detection device to monitor the trigger housing state, and a control device to adjust the output torque based on detected states, allowing for varied pressing and rebounding experiences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a spring mechanism is used for trigger reset, then the structure is simple, but the user experience is poor due to limited feedback control
Solution Approach 1:
The patent replaces the traditional spring-based mechanical reset mechanism with an electromagnetic drive device. This substitution enables active control of the trigger housing through electromagnetic forces, allowing for varied feedback forces and enhanced user experience while maintaining structural simplicity through integrated motor housing.
Solution Approach 2:
The patent implements dynamic control by using a drive device that can adjust its output torque based on detected trigger housing states. The system transitions from a static spring mechanism to a dynamic system that adapts feedback forces in real-time, providing rich tactile experiences during pressing and rebounding phases.
2Device complexity
If only pressing force is considered, then the structure is simple, but the feedback control is insufficient
Solution Approach 1:
The patent implements a feedback control system where a detection device monitors the trigger housing state and sends signals to a control device. The control device adjusts the drive device's output torque based on this feedback, enabling precise control of feedback forces during both pressing and rebounding, thereby enhancing reliability and user experience.
