Accessory Device Lever Mechanism for Game Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing accessory devices for game controllers lack usability, particularly in terms of efficiently operating multiple buttons, and are not adaptable to different game controller shapes.
Innovation Solution
The accessory device includes a compartment to securely hold a game controller, with movable portions that allow users to press buttons on the controller using a lever mechanism, and is designed to accommodate game controllers of varying shapes through adjustable engagement portions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If accessory units are designed with fixed button positions, then the structure is simple, but the usability is poor when used with different game controller shapes
Solution Approach 1:
The patent employs movable portions that can shift position to accommodate different game controller shapes. The movable portions include pressing portions that can move toward buttons and releasing portions that can adjust their positions, transforming the static structure into a dynamic one that adapts to various controller configurations.
Solution Approach 2:
The accessory unit is designed with engagement portions that can engage with different types of game controllers through a standardized interface. The movable portions serve multiple functions: they can press buttons, adjust positions, and accommodate various controller shapes, making the accessory universally compatible while maintaining a relatively simple overall structure.
2Force
If multiple buttons are operated directly without mechanical advantage, then the device structure is simple, but the force required to press buttons is high
Solution Approach 1:
The patent employs lever mechanisms with curved or angled paths for the movable portions. The pressing portions move along curved trajectories that provide mechanical advantage, allowing users to press buttons with reduced force while the lever mechanism translates this motion into effective button pressing action.
Solution Approach 2:
The movable portions act as intermediaries between the user's input and the game controller buttons. These intermediaries include lever arms and pressing portions that amplify the user's input force and translate it into precise button pressing movements, reducing the direct force requirement while adding functional complexity.
3Ease of operation
If the accessory device allows easy button operation, then the usability is improved, but the controllability and precision may be compromised
Solution Approach 1:
The lever mechanisms are designed with carefully calibrated curved paths that ensure the pressing portions follow precise trajectories. This curvature allows for smooth, easy operation while maintaining accurate button engagement, as the geometric design inherently guides the motion along the correct path.
Solution Approach 2:
The movable portions are designed to provide tactile feedback to the user during operation. As the levers move and engage with the buttons, the user can feel the engagement points and resistance changes, which helps maintain precision while allowing for easy operation. The mechanical feedback loop ensures accurate button pressing without requiring complex electronic sensors.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enhances usability by allowing easy operation of multiple buttons with reduced force and improves controllability, while also enabling compatibility with different game controller shapes.
Implementation Method 1
The accessory device includes a compartment, a grip portion, a first movable portion and a second movable portion... The first operation portion is configured to be pressed by one hand of the user holding the grip portion... The first button depression portion is configured to move toward the first button of the game controller secured in the compartment, thereby pressing the first button

AI summary
An accessory device includes a rim; a bridge provided between portions of the rim and having a cavity configured to removably secure a game controller at least partly therein; a first key; and a first pusher configured to push a first button of the game controller secured in the cavity in accordance with movement of the first key. The first key includes a first operation surface at least partly facing upward and configured to be pressed by a finger of the user whilst the user holds the rim, the first operation surface positioned at least partly rearward of the rim and extending at least partly in the right-left direction from radially inside of the rim to behind the rim.
