Removable Trigger Accessories for Game Controllers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional game controllers are designed with a 'one size fits all' approach, failing to accommodate individual user preferences in shape, size, color, texture, or other attributes of controls, leading to suboptimal gaming experiences.
Innovation Solution
A customizable game controller with removable trigger accessories that can be swapped out tool-free, offering various sizes, materials, ranges of motion, spring tensions, and finger positions, allowing users to customize controls for specific games or personal preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional game controllers use a fixed, one-size-fits-all design, then manufacturing simplicity is maintained, but user comfort and performance are compromised due to inability to accommodate individual preferences
Solution Approach 1:
The trigger assembly is divided into separate components: a base trigger integrated with the controller body and removable trigger accessories that can be detached and replaced. This segmentation allows users to swap between different trigger types (e.g., traditional triggers, thumb triggers, extended triggers) without modifying the entire controller, thus achieving customization while maintaining relatively simple overall structure
Solution Approach 2:
The retention feature is designed as a universal mounting mechanism that can accommodate multiple types of trigger accessories through a standardized interface. This multi-functional retention system allows a single controller to support various trigger configurations (traditional, thumb, extended, customized) using the same attachment mechanism, resolving the contradiction between versatility and complexity
2Ease of operation
If removable trigger accessories are added to enable customization, then user preferences and game-specific optimization are improved, but the device complexity increases
Solution Approach 1:
The retention feature employs magnetic attraction instead of traditional mechanical fastening systems (screws, clips, or latches). The magnetic field provides sufficient holding force to secure trigger accessories during gameplay while allowing easy removal by simply pulling the accessory away. This substitution eliminates complex mechanical retention structures, achieving tool-free swapping without significantly increasing device complexity
Solution Approach 2:
The magnetic retention system allows for adjustable magnetic strength parameters to optimize the balance between secure attachment during use and easy removal when needed. By tuning the magnetic field parameters, the system achieves both strong holding force for gameplay and simple release action, resolving the contradiction between ease of operation and device complexity

AI summary
A game controller includes a trigger-activation sensor, a sensor-activation feature, and a trigger-retention feature. The sensor-activation feature is moveable relative to the trigger-activation sensor. The trigger-activation sensor outputs a control signal based on a relative position of the sensor-activation feature and the trigger-activation sensor. The trigger-retention feature is configured to removably affix a selected removable trigger accessory to the game controller. The selected removable trigger accessory is one of a plurality of differently configured removable trigger accessories removably affixable to the game controller. The selected removable trigger accessory is configured to change the relative position of the sensor-activation feature and the trigger-activation sensor based on finger manipulation of the selected removable trigger accessory when the selected removable trigger accessory is removably affixed to the game controller.
