Game Controller Grip Layout for Accessible Buttons Without Mispresses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a demand for improving the operability of conventional controllers that are grasped by a user with both hands, particularly in terms of the design and layout of buttons and grips.
Innovation Solution
The game controller features a unique design with left and right grips that form valleys, buttons positioned along these valleys with varying edge distances and curvatures, and a button layout that matches the shape of a user's fingers for enhanced grip and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If buttons are positioned closer to the valley bottom for better accessibility, then ease of operation improves, but the risk of accidental presses increases
Solution Approach 1:
The button operation surfaces have non-uniform width distribution - wider at the edge side and narrower at the center side. This local variation in geometry allows the button to be positioned closer to the valley bottom for easier access while the narrower portion near the valley bottom reduces accidental activation risk.
Solution Approach 2:
The operation surfaces incorporate curved edges with different radii - the first edge has a larger radius of curvature than the second edge. This curvature design creates a gradual transition zone that facilitates intentional pressing while making accidental presses less likely due to the geometric profile.
2Ease of operation
If operation surfaces are made wider for better finger fit, then ease of operation improves, but device complexity increases
Solution Approach 1:
Instead of making the entire operation surface uniformly wide, the design applies local quality by having the width vary along the button - wider at the edge side for finger fit and narrower at the center side to reduce complexity in other areas.
3Reliability
If buttons are positioned further from the valley bottom to reduce accidental presses, then reliability improves, but ease of operation deteriorates
Solution Approach 1:
The curved edge design with different radii creates a geometric profile that naturally guides finger placement. The larger radius at the first edge provides a broader contact area for intentional presses, while the overall curvature maintains distance from the valley bottom to prevent accidental activations.

AI summary
An example of a game controller includes a main body portion, an input section at a front surface of the main body portion, a left grip, a right grip, a first button, and a second button. The left grip protrudes from a left side portion of the main body portion so as to at least partly form, together with the main body portion, on a back surface of the game controller. The right grip protrudes from a right side portion of the main body portion so as to at least partly form, together with the main body portion, on the back surface of the game controller. The first and second buttons are respectively at the left grip and the right grip extending along the first valley bottom and the second valley bottom while being spaced apart from a first valley bottom and a second valley bottom.
