Solution Overview
Problem
Computer hardware is susceptible to corrosion from airborne corrosive agents like sulfuric acid and nitric acid, leading to reliability issues and increased maintenance costs due to the need for part replacement.
Innovation Solution
A computer system that reads current internal corrosion levels from an internal corrosion sensor, calculates differences, and performs actions to adjust internal temperature based on threshold levels to mitigate corrosion, such as decreasing temperature by increasing airflow or reducing processor load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the computer operates at high temperature to maintain performance, then processing speed is improved, but corrosion rate increases
Solution Approach 1:
The system dynamically adjusts temperature based on operational conditions and corrosion risk. The controller monitors internal temperature and corrosion sensor data, then dynamically changes cooling fan speeds or processor throttling levels to balance performance needs with corrosion prevention, rather than maintaining a fixed temperature regime
Solution Approach 2:
The system changes temperature parameters adaptively based on corrosion sensor readings. When corrosion is detected, the controller modifies operating temperature parameters by adjusting fan speeds, enabling processors to run at lower temperatures during high-corrosion conditions while maintaining acceptable performance levels
2Reliability
If cooling airflow is increased to reduce temperature, then corrosion rate is reduced, but energy consumption increases
Solution Approach 1:
The system applies partial cooling action only when and where needed. Instead of continuously running cooling fans at high speed, the controller activates cooling only when corrosion sensors detect problematic conditions or when temperature thresholds are exceeded, applying just enough cooling to address the specific corrosion risk without excessive energy consumption
Solution Approach 2:
The system uses periodic monitoring and responsive cooling activation. The corrosion sensors continuously monitor conditions, and the controller periodically adjusts cooling fan speeds based on detected corrosion levels, creating an on-demand cooling regime that consumes energy only when corrosion prevention is actually needed rather than continuous high-energy cooling

Function Achieved in This Case
The system effectively reduces the rate of corrosion by controlling temperature and airflow, thereby extending the lifespan of computer components and reducing maintenance costs.
Implementation Method 1
Airborne corrosive agents, such as sulfuric acid and nitric acid, can corrode a filament of the corrosion sensor, thereby changing an electrical resistance of the corrosion sensor
Implementation Method 2
A controller 150 receives an indication from the internal corrosion sensor 126 and increases a speed of a cooling fan 128
Implementation Method 3
increases a speed of a cooling fan 128 that blows air across heat sinks of one or more computer components

AI summary
In an embodiment, a current internal corrosion level at a current time is read from an internal corrosion sensor that is internal to a computer. An internal corrosion difference is calculated between the current internal corrosion level and a previous internal corrosion level. Upon determining that the internal corrosion difference is more than a first threshold amount, a first action is performed that decreases an internal temperature of the computer. In a further embodiment, upon determining that the internal corrosion difference is less than a second threshold amount, a second action is performed that allows the internal temperature of the computer to increase.
