Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computer systems require users to manually detach the casing and navigate complex circuit layouts to perform an RTC reset, which is inconvenient and risks damage to the system.
Innovation Solution
A switching circuit module that allows users to reset the computer system by generating a control signal to cut off the RTC reset high-level signal using a Hall Effect switch or physical button, enabling RTC resetting without casing detachment through a processing module, chipset, and switch module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user manually detaches the casing and navigates complex circuit layouts to perform RTC reset, then the RTC reset function can be achieved, but the operation becomes inconvenient and the system may be damaged
Solution Approach 1:
The patent introduces a control switch as an intermediary device between the user and the RTC reset function. This switch is integrated into the system's internal circuitry, allowing users to trigger the reset function without physically accessing internal components. The control switch acts as a mediator that translates user input into the appropriate reset signal while protecting the system from damage caused by improper manual handling of internal circuits
Solution Approach 2:
The patent extracts the RTC reset function from the complex internal circuit layout and creates a dedicated control interface. By separating the reset function from the complicated circuit board navigation, the system provides a simple external control mechanism that eliminates the need for users to detach casings or locate specific pins on the circuit board, thereby improving ease of operation while maintaining system reliability
2Ease of operation
If the user detaches the casing to access the battery or RTC reset pin, then the RTC reset can be performed, but the operation complexity increases
Solution Approach 1:
The control switch serves as an intermediary that simplifies the reset procedure by providing a dedicated external interface. Users interact with this simple switch rather than navigating complex internal circuits, effectively reducing the operational complexity from multiple steps (detaching casing, locating components, making connections) to a single button press or switch operation
Solution Approach 2:
The control switch is designed as a universal interface that handles the RTC reset function regardless of the specific computer system configuration. This multi-functional approach allows the same simple control mechanism to work across different systems without requiring users to understand or access system-specific internal layouts, thereby reducing overall procedure complexity

Function Achieved in This Case
Enables safe and convenient RTC resetting within the computer system, preventing potential damage and simplifying the reset process by using a user-operated control switch to manage the RTC reset signal.
Implementation Method 1
The first control switch is a Hall Effect switch and electrically connected to the processing module for being operated by the user to generate a first control signal by using a magnet

AI summary
A switching circuit module, a computer system, and a method for controlling computer system reset thereof are disclosed. The switching circuit module is used for allowing a user to cut off a RTC reset high-level signal generated by an internal power supply module at a shutdown state. The switching circuit module includes a processing module, a first control switch, a chipset, and a switch module. The first control switch is used for being operated by the user to generate a first control signal. The chipset is used for receiving a RTC reset signal. When the processing module continuously receives the first control signal to exceed a first setting time, the processing module further determines whether stop receiving the first control signal in a second setting time. If yes, a pulse signal is generated to cut off the RTC reset high-level signal transmitted to the chipset.
