Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for updating or maintaining computer systems require physically opening the housing to update flash memory, which is complex and prone to errors during de-soldering and soldering, leading to potential system malfunction.
Innovation Solution
A super I/O module with a controller, signal detector, and selector that allows for selective routing of input signals based on identification codes, enabling control, debugging, or updating of internal circuits without removing the housing by providing a method to selectively direct signals to appropriate function circuits within the computer system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the maintenance engineer opens the housing to update flash memory using traditional methods, then the flash memory can be updated, but the procedure becomes complicated and time-consuming
Solution Approach 1:
The patent introduces a super I/O module as an intermediary device that includes a flash memory update function. This module provides a dedicated interface and control mechanism for updating flash memory, eliminating the need for engineers to manually open the housing and perform complex de-soldering and soldering operations. The super I/O module acts as a mediator between the external update device and the internal flash memory, simplifying the entire update procedure while maintaining reliability.
Solution Approach 2:
The patent extracts the flash memory update function from the traditional housing assembly process and integrates it into a separate super I/O module. This allows the update operation to be performed independently through a dedicated interface, separating the update function from the physical housing manipulation and reducing procedural complexity.
2Reliability
If the maintenance engineer de-solders and solders the flash memory manually, then the flash memory can be updated, but errors may occur during the process
Solution Approach 1:
The super I/O module serves as an intermediary that handles the flash memory update process electronically without requiring physical manipulation of the flash memory chip. The module includes dedicated circuitry and control logic that manages the update operation through software or electrical signals, eliminating manual de-soldering and soldering operations and their associated errors.
Solution Approach 2:
The patent replaces the mechanical process of manually de-soldering and soldering the flash memory with an electronic/software-based update mechanism. The super I/O module provides an electrical interface that allows flash memory updates to be performed through data transmission and control signals, substituting mechanical manipulation with electronic control and improving ease of operation.
3Ease of manufacture
If the flash memory is de-soldered for updating, then the data can be rewritten, but the computer system may not work normally if de-soldering or soldering fails
Solution Approach 1:
The super I/O module acts as a protective intermediary between the flash memory and the external update process. It includes error detection and correction circuitry, as well as validation mechanisms that ensure the update process completes successfully before committing changes. This intermediary layer protects the system from potential failures during the update process, maintaining operational reliability while enabling easy updates.
Solution Approach 2:
The patent implements prior cushioning by incorporating error handling and validation mechanisms in the super I/O module before the actual update occurs. The module performs pre-update checks, maintains backup copies of critical data, and implements rollback mechanisms to prevent system failure if an update fails partway through. This preparatory protection ensures system reliability during the update process.
4Ease of repair
If the housing is opened to access internal circuits, then maintenance can be performed, but the process becomes complicated and time-consuming
Solution Approach 1:
The super I/O module provides an external interface that mediates access to internal circuits without requiring physical opening of the housing. Through this intermediary interface, maintenance engineers can perform diagnostics, updates, and configuration changes on internal components including flash memory using electrical connections already present on the motherboard, eliminating the time-consuming process of opening and closing the housing repeatedly.
Solution Approach 2:
The super I/O module serves multiple maintenance functions through a single integrated interface, including flash memory updates, system diagnostics, configuration changes, and circuit testing. This multi-functional approach consolidates various maintenance tasks that would otherwise require different access methods and procedures, reducing both complexity and time requirements for routine maintenance operations.

AI summary
A super I/O module for controlling at least one I/O port of a computer system is provided. The super I/O module includes a controller, a signal detector and a selector. The controller supports functions corresponding to the I/O port. The signal detector receives an input signal from the I/O port, and detects whether the input signal has an identification code. When detecting that the input signal has the identification code, the signal detector generates a selection signal according to the identification code. The selector receives the selection signal and selectively provides the input signal to the controller or a function circuit of the computer system according to the selection signal.
