Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for erasing environment configuration memory on a motherboard are inconvenient for users, requiring them to switch off the power source, open the computer housing, and manually connect a jump circuit to ground voltage.
Innovation Solution
A computer system with a power switch, reset switch, and an erasing control circuit that connects the power supply pin to ground voltage when both switches are triggered, simplifying the erasure process without requiring users to access internal components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a jump circuit is used to erase environment configuration memory, then the erasing function is achieved, but the operation becomes complex and inconvenient for users
Solution Approach 1:
The patent introduces an erasing control circuit as an intermediary component that mediates between the user-friendly switch operation and the actual memory erasing function. This control circuit automatically manages the complex jump circuit connections when the power and reset switches are simultaneously pressed, shielding users from the complexity while enabling the erasing function.
Solution Approach 2:
The erasing control circuit automatically performs the erasing operation when the power and reset switches are simultaneously pressed, without requiring user intervention to manually configure jump circuits. The system serves itself by automatically executing the complex sequence of operations needed to erase the environment configuration memory.
2Reliability
If manual jump circuit connection is required, then precise control of memory erasing is achieved, but user convenience deteriorates
Solution Approach 1:
The erasing control circuit automatically executes the precise control sequence needed for reliable memory erasing when the power and reset switches are simultaneously pressed. The system performs the complex control operations itself, maintaining reliability while eliminating the need for users to manually configure jump circuits.
Solution Approach 2:
The patent replaces the mechanical manual connection of jump circuits with an automated electronic control system. The erasing control circuit uses electronic switching and control signals to achieve the same function, substituting the mechanical user action with an automated electronic process that maintains precision while improving convenience.
3Reliability
If the erasing circuit is hidden inside the computer housing, then system integrity is maintained, but accessibility for users deteriorates
Solution Approach 1:
The erasing control circuit acts as an intermediary that bridges the gap between the external user interface (power and reset switches) and the internal memory erasing function. It allows users to trigger the erasing operation through easily accessible switches while the actual control circuit remains integrated within the system, maintaining both accessibility and system integrity.
Solution Approach 2:
The power and reset switches serve multiple functions: their normal individual operations maintain system power control and reset functions, while their simultaneous pressing activates the memory erasing function. This multi-functionality allows the same accessible components to serve both user convenience and system integrity purposes.

AI summary
A computer system includes a power switch, a reset switch, environment configuration memory, and an erasing control circuit. The power switch is for starting the computer system as triggered. The reset switch is for resetting the computer system as triggered. The environment configuration memory is for storing an operational environment setting of the computer system. The environment configuration memory has a power supply pin. The erasing control circuit is connected to the power switch, the reset switch and the power supply pin. The erasing control circuit connects the power supply pin to a ground voltage as the power switch and the reset switch are triggered simultaneously.
