Dual-Mode Directional Pad Assembly for Speed and Precision
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handheld gaming controllers typically offer only one type of directional pad (D-pad), either swivel or discrete, which limits user flexibility as different games require either smooth sliding or precise directional control, necessitating the need for multiple controllers.
Innovation Solution
A directional pad assembly that includes a directional-control unit with a plate-like structure and plunger elements, allowing it to be operable in both swivel and discrete modes by switching between swivel and discrete directional pad caps, providing a versatile solution for various gaming needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a swivel D-pad is used, then smooth sliding and fast response are improved, but precision in direction deteriorates
Solution Approach 1:
The patent implements a dynamic D-pad mechanism where the plate-like structure can switch between two operational states: swivel mode for fast response in fighting games, and discrete mode for precise directional control in shooting games. The plunger elements are designed to slide along curved guides that enable both rotational swiveling motion and linear pressing motion, allowing the system to adapt its degree of freedom based on gameplay requirements.
2Measurement precision
If a discrete D-pad is used, then precision in direction is improved, but smooth sliding and fast response deteriorate
Solution Approach 1:
The patent implements a dynamic D-pad mechanism where the plate-like structure can switch between two operational states: swivel mode for fast response in fighting games, and discrete mode for precise directional control in shooting games. The plunger elements are designed to slide along curved guides that enable both rotational swiveling motion and linear pressing motion, allowing the system to adapt its degree of freedom based on gameplay requirements.
3Device complexity
If only one type of D-pad is provided, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The patent creates a universal D-pad assembly that can function in multiple modes (swivel and discrete) within a single controller. The mechanism includes a plate-like structure with plunger elements that can operate in either swivel mode or discrete mode, eliminating the need for users to own multiple controllers for different game types. The switching mechanism allows seamless transition between modes to accommodate various gaming requirements.

AI summary
A directional pad assembly including a directional-control unit having a plate-like structure and two or more plunger elements slidable relative to the plate-like structure; a main support structure to support a centre of the plate-like structure such that the plate-like structure is multi-directional tiltable; an interface frame structure suspended above the plate-like structure of the directional-control unit and in a fixed spatial relationship and non-movable relative to the main support structure; and two or more switches arranged around the main support structure and aligned to the two or more plunger elements. The directional-control unit being operable between a first mode, whereby the plate-like structure is tiltable, and a second mode, whereby the two or more plunger elements are individually slidable relative to the plate-like structure, to activate the two or more switches.
