Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If Bluetooth technology is used for wireless audio transmission, then wireless convenience is improved, but audio latency increases due to signal interference
Solution Approach 1:
The patent segments the wireless audio transmission into two independent pathways: one using Bluetooth for general audio and another using a dedicated 2.4GHz wireless channel for game audio. This segmentation allows each pathway to be optimized for its specific purpose, with the 2.4GHz pathway providing low-latency transmission for gaming while Bluetooth handles other audio needs.
Solution Approach 2:
The game controller acts as an intermediary device that receives audio from the mobile device and re-transmits it through a dedicated 2.4GHz wireless module. This intermediary approach creates a direct wireless connection between the controller and headphones, bypassing the interference-prone Bluetooth stack and reducing audio latency for gaming.
2Speed
If multiple audio modules are used to reduce latency, then audio transmission speed is improved, but device complexity increases
Solution Approach 1:
The game controller is designed with multi-functionality, serving both as a game input device and as an audio transmission device. By integrating a 2.4GHz wireless audio module into the controller, it can handle both game control and low-latency audio transmission, eliminating the need for separate dedicated audio equipment.
Solution Approach 2:
The patent implements preliminary pairing between the game controller and headphones, establishing a dedicated 2.4GHz wireless connection before gaming begins. This preliminary action ensures that the low-latency audio pathway is ready in advance, allowing immediate switching to the optimized audio route when gaming starts, without adding complexity during active use.

AI summary
A game controller for a mobile device is provided. The game controller includes a control module, a first audio module, and a second audio module. The mobile device includes a first wireless communication module. The first audio module is wirelessly connected to an audio device. The second audio module is electrically connected to the mobile device, so as to control the mobile device to be wirelessly connected to the audio device. A pairing between the audio device and the first audio module and a pairing between the audio device and the first wireless communication module of the mobile device are performed before the audio device is used. The control module generates a control command according to a category of audio information of the mobile device, so as to output the audio information to the audio device through the first audio module or the second audio module.
