Wireless Charging Adapter With Rear Control Keys for Game Controllers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless charging solutions for game controllers lack the ability to enhance gameplay by integrating additional control buttons, limiting their functionality during charging.
Innovation Solution
A wireless charging adapter with strategically positioned duplicate game controller buttons on the backside, allowing for enhanced gameplay and command input while charging, and optionally omitting the charging feature for standalone control functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a wireless charging adapter is added to the game controller, then charging convenience is improved, but the controller structure becomes more complex
Solution Approach 1:
The wireless charging adapter is designed as a separate, detachable module that attaches to the rear portion of the controller. This segmentation allows the charging function to be added without permanently complicating the controller structure, as the adapter can be removed or replaced independently.
Solution Approach 2:
The adapter serves multiple functions: wireless charging through inductive coupling with a base, and additional game control through duplicate buttons. This multi-functionality justifies the added structural complexity by providing dual benefits in one component.
2Adaptability or versatility
If duplicate control buttons are added to the adapter, then gameplay functionality is enhanced, but the adapter design becomes more complex
Solution Approach 1:
The adapter merges two distinct functions into a single device: wireless charging capability and additional game control buttons. By combining these functions in one integrated component attached to the controller rear, the design avoids the complexity of separate devices while enhancing versatility.
Solution Approach 2:
The additional control buttons are positioned on the rear portion of the adapter, utilizing the three-dimensional space of the adapter structure. This spatial arrangement allows extra functionality without interfering with the front-facing controller interface, effectively adding controls in a different dimensional space.
3Ease of operation
If the adapter is made mechanically engageable without connectors, then ease of attachment is improved, but structural strength may be reduced
Solution Approach 1:
The adapter employs a dynamic mechanical engagement system with snap-fit features that allow easy hand attachment and detachment. The engagement structure includes flexible elements that provide sufficient holding strength during use while enabling tool-free installation and removal, balancing strength requirements with ease of operation.

AI summary
A wireless charging adapter (212) that can snap onto a computer game controller (200) can be inductively coupled to a charging base (230) to wirelessly recharge a battery (204) in the controller (200). The adapter (212) also can include keys (220) that mirror keys (206) on the controller (200) so that a gamer can remove the adapter (212) with controller (200) from the charging base (230), keep the adapter (212) on the controller (200), and use both the controller keys (206) and adapter keys (220) to control a computer game.
