Gamepad Trigger Force Feedback Module
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gamepads lack the capability to effectively convey immersive feedback to users due to limited space, with simple vibration devices failing to meet user experience demands for realistic game interactions.
Innovation Solution
A force feedback module for gamepads, comprising a drive mechanism, a gamepad trigger, and a unidirectional transmission mechanism that transmits feedback force from the drive mechanism to the trigger, allowing for pushback and vibration effects while maintaining compatibility with both force feedback and non-force feedback modes, and incorporating a reset mechanism to ensure independent operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a force feedback mechanism is added to the gamepad, then user experience and realism are improved, but the device complexity and space requirements increase
Solution Approach 1:
The force feedback mechanism is integrated within the existing gamepad structure by nesting the drive mechanism and unidirectional transmission mechanism inside the gamepad housing. The transmission mechanism is coupled between the drive mechanism and the trigger, allowing force feedback functionality to be embedded without significantly increasing external dimensions or complexity.
Solution Approach 2:
A unidirectional transmission mechanism is introduced as an intermediary component between the drive mechanism and the gamepad trigger. This mediator transmits feedback force in one direction while allowing the trigger to move freely in the opposite direction, enabling force feedback functionality without requiring direct coupling that would increase complexity.
2Reliability
If a force feedback mechanism is added to the gamepad, then feedback capability is improved, but the volume and space consumption increase
Solution Approach 1:
The force feedback mechanism components are nested within the existing gamepad volume. The drive mechanism and transmission mechanism are positioned inside the gamepad housing, utilizing available internal space rather than requiring additional external volume, thus maintaining compact form factor while adding feedback capability.
Solution Approach 2:
The unidirectional transmission mechanism enables force feedback in a specific dimensional direction (along the trigger axis) while allowing free movement in the opposite direction. This selective force transmission in one dimension allows effective feedback capability with minimal space requirements.
3Force
If a unidirectional transmission mechanism is used, then force feedback transmission is improved, but the device complexity increases
Solution Approach 1:
The unidirectional transmission mechanism serves as an intermediary that selectively transmits force in one direction while blocking force in the opposite direction. This mediator component enables effective force feedback transmission to the trigger without requiring complex bidirectional control systems, maintaining relatively simple device architecture.
