Solution Overview
Problem
Window moisture condensation in humid environments, such as sanitary sewers, impairs optical systems by scattering light and de-focusing instruments, and existing solutions like electrical heaters consume excessive power, which is a concern for remote sites with limited power budgets.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical heaters are used to prevent condensation continuously, then condensation prevention is effective, but power consumption increases excessively
Solution Approach 1:
The system uses periodic sensing and conditional activation of the mitigation device based on detected condensation conditions rather than continuous operation. The controller activates the mitigation device only when condensation is detected, creating a periodic rather than continuous operation cycle that reduces power consumption while maintaining effectiveness.
Solution Approach 2:
The system implements feedback control by using sensors to detect condensation conditions and feeding this information back to the controller, which then conditionally activates the mitigation device. This closed-loop feedback mechanism ensures the device operates only when needed, optimizing both condensation prevention and power consumption.
2Illumination intensity
If condensation mitigation devices are activated continuously, then optical clarity is maintained, but power budget is exceeded
Solution Approach 1:
The mitigation device operates periodically based on condensation detection events rather than continuously. The system checks for condensation conditions at intervals and activates the mitigation device only when condensation is present, maintaining optical clarity while operating within power budget constraints.
Solution Approach 2:
The system performs preliminary detection of condensation conditions using sensors before activating the mitigation device. This preliminary action allows the system to prepare for potential optical degradation and activate mitigation only when necessary, rather than operating continuously.
3Use of energy by moving object
If sensors and algorithms are used for conditional activation, then power consumption is reduced, but device complexity increases
Solution Approach 1:
The system uses self-service automation where sensors automatically detect condensation conditions and the controller automatically activates the mitigation device based on predetermined conditions. This self-service approach reduces the need for manual monitoring and intervention, offsetting the increased device complexity with operational simplicity.
Solution Approach 2:
The system replaces manual monitoring and mechanical condensation removal with automated sensing and electronic control mechanisms. This substitution uses electronic sensors and algorithms to detect and respond to condensation conditions, reducing power consumption through intelligent control while managing complexity through electronic rather than mechanical systems.
