Ergonomic Video Game Controller with Integrated Action Buttons
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard video game controllers are uncomfortable as they require players to remove their thumb from the joystick to press buttons, limiting simultaneous joystick and button input capabilities.
Innovation Solution
A video game controller design featuring dual joysticks with pivoting portions and integrated buttons, including a heart rate sensor, allowing for joystick movement and button depression without thumb removal, facilitated by ergonomic finger grooves and a base for power connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard controller design is used with a single joystick and buttons, then the controller structure is simple, but the player must remove the thumb from the joystick to press buttons, limiting simultaneous input capability
Solution Approach 1:
The controller is divided into two separate joystick bodies (first joystick with directional pad, second joystick with action buttons), each capable of independent operation. This segmentation allows the player's left and right thumbs to operate different controls simultaneously without interference, resolving the contradiction between operational ease and structural simplicity.
Solution Approach 2:
The controller design transitions from a single-plane layout to a multi-dimensional configuration with two elongate joystick bodies extending in different directions from a base. This spatial arrangement creates independent operational zones for each hand, enabling simultaneous joystick and button input while maintaining a relatively simple overall structure.
2Ease of operation
If the joystick and buttons are positioned close together, then the controller size is reduced, but the player cannot press buttons without moving the thumb from the joystick
Solution Approach 1:
The two joystick bodies are positioned asymmetrically relative to the base, with the first joystick extending in one direction and the second joystick extending in another direction. This asymmetric arrangement optimizes the spatial relationship between controls for each hand, allowing thumbs to rest on joysticks while fingers can easily reach buttons without requiring thumb movement, all within a compact form factor.
3Adaptability or versatility
If additional buttons and features are added to the controller, then the functionality is improved, but the controller becomes more complex and less comfortable to hold
Solution Approach 1:
The controller incorporates localized ergonomic features including finger receiving grooves on the first and second joystick bodies. These grooves are strategically positioned to accommodate specific fingers, providing secure grip points that enhance comfort during extended use. This local quality enhancement allows for additional buttons and features without compromising overall grip comfort.
Solution Approach 2:
The controller includes pivoting portions that enable dynamic adjustment of the joystick bodies relative to the base. This dynamic capability allows the controller to adapt to different hand sizes and gripping styles, maintaining comfort and control versatility simultaneously. The pivoting mechanism provides flexibility without adding significant structural complexity.
