Video Game Console BGA Circuit for Selective Wi-Fi Disabling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for disabling Wi-Fi functionality in video game consoles are cumbersome and not fail-safe, particularly due to the integrated nature of WLAN, Bluetooth, and power management chips, making it difficult to selectively disable Wi-Fi without affecting other functions.
Innovation Solution
A method involving the creation of an open line on the BGA circuit and subsequent short-circuiting using a capacitor to redirect signals to ground, combined with a remotely controlled short-circuit mechanism to manage wireless connection status, allowing selective disabling and re-enabling of Wi-Fi.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Wi-Fi functionality is disabled through traditional methods (airplane mode, antenna removal, signal disruption), then Wi-Fi is blocked, but the process is time-consuming and not fail-safe
Solution Approach 1:
The patent applies preliminary action by pre-configuring a specific solder pad on the BGA circuit with a controlled impedance value (50-100 ohms) that is different from the normal circuit impedance. This pre-prepared feature allows for rapid and reliable Wi-Fi disabling through a simple capacitor shorting action without requiring complex real-time analysis or multiple steps, thus achieving both time efficiency and reliability
Solution Approach 2:
The patent replaces traditional mechanical/discrete methods (physical antenna removal, complex circuit modification) with an electronic field-based approach using capacitor shorting on a pre-configured solder pad. This substitution enables fail-safe Wi-Fi disabling through electrical field control rather than mechanical manipulation, achieving both reliability and speed
2Reliability
If Wi-Fi is disabled by permanently enabling airplane mode or removing antenna, then Wi-Fi is blocked, but other console functions may be affected
Solution Approach 1:
The patent applies local quality by targeting a specific localized feature (a particular solder pad on the BGA circuit) with distinct electrical properties (controlled impedance of 50-100 ohms) rather than modifying the entire circuit or using generic disabling methods. This localized approach with unique electrical characteristics enables selective Wi-Fi disabling without affecting other console functions, resolving the contradiction between selectivity and circuit complexity
Solution Approach 2:
The patent introduces a capacitor as an intermediary element that can be strategically placed to short the specific solder pad when needed. This intermediary provides a simple, reversible mechanism for Wi-Fi disabling that doesn't require permanent hardware modification or complex circuit manipulation, achieving selective disabling while maintaining overall system simplicity
3Ease of operation
If traditional hardware methods are used to disable Wi-Fi, then Wi-Fi is blocked, but the methods are not fail-safe and may affect other functions
Solution Approach 1:
The patent makes the solder pad ready in advance with a controlled impedance value (50-100 ohms) that is distinct from the normal circuit. This preliminary configuration ensures that when the capacitor is applied, the shorting action is immediate and reliable, achieving both ease of operation (simple capacitor application) and failure-safety (definitive circuit interruption without affecting other functions)

AI summary
A system and method for disabling the Wi-Fi on a handheld console whereby the handheld console may have an integrated chip that is a ball grid array whereby each solder ball provides certain voltages or data signals whereby the approach will be determined based on the specific handheld console as well as other factors including new manufacturer integrated chips, chipset architecture, software/firmware changes, or where is the best location on the handheld console for each circuit line to apply the short cut for the circuit to not be completed by either diverting the signal to another location on the logic board such as ground or creating an open line.
