Multi Single-Axis Game Controller Axis Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dual-axis game controllers experience interference during precise rapid control inputs in games like Battle Royale and First Person Shooter, where up/down and left/right inputs are biased, limiting accuracy.
Innovation Solution
A multi, single-axis game controller with a pair of hand units connected via an articulable joint and a switching actuator, allowing temporary reassignment of thumb stick functionality to other control elements, enabling independent and interference-free axis control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dual-axis control is used in conventional controllers, then comprehensive control capability is provided, but interference occurs between up/down and left/right inputs during precise rapid control
Solution Approach 1:
The controller divides the control function into separate single-axis thumb sticks instead of using a combined dual-axis thumb stick. Each thumb stick is dedicated to a specific axis (left/right or up/down), eliminating the interference that occurs when both axes share a single control element. This segmentation allows precise rapid control inputs on one axis without bias from the other axis.
Solution Approach 2:
The controller transitions from a two-dimensional dual-axis control interface to a three-dimensional configuration by adding multiple independent control elements (separate thumb sticks for each axis). This dimensional change allows each axis to have its own dedicated control input, removing the cross-axis interference present in conventional dual-axis controllers.
2Device complexity
If thumb stick functionality is fixed, then simple controller design is maintained, but flexibility for different game types is limited
Solution Approach 1:
The controller incorporates a switching actuator that dynamically reassigns the functionality of thumb sticks between different control elements based on game requirements. This dynamic reconfiguration allows the same physical controller to adapt to different game types (e.g., Battle Royale, First Person Shooter, racing games) without changing the physical hardware, maintaining simple design while achieving high versatility.
Solution Approach 2:
The thumb sticks are designed to perform multiple functions through the switching actuator. The same thumb stick can be reassigned to control different axes or control elements depending on the game mode, making the controller universally applicable to various game types while maintaining a consistent physical design.
3Ease of operation
If bumper buttons and triggers are positioned on the top of the controller, then accessibility with index fingers is improved, but rapid switching between bumper and trigger becomes cumbersome
Solution Approach 1:
The controller segments the control elements by placing bumpers and triggers on opposite sides of the controller, allowing each hand to independently access its designated controls without interference. This spatial segmentation enables rapid switching between bumper and trigger by simply moving the hand or wrist, eliminating the cumbersome finger movement required in conventional designs where both controls are on the same side.

AI summary
A multi, single-axis game controller including a pair of hand units in a spaced apart configuration, each hand unit configured to be held in one hand by the user and at least one of the pair of hand units having at least one button control pad and at least one thumb stick; and a switching actuator to at least temporarily reassign at least some input functionality from the at least one thumb stick to another control element provided on at least one of the hand units.
