Solution Overview
Problem
Existing ventilation systems lack integrated air sterilization capabilities and efficient coordination between ventilation and air sterilization functions, particularly in air conditioners, which can lead to inadequate treatment of viruses and bacteria.
Innovation Solution
A ventilation device with a coordinated control system that adjusts the ventilation amount and ultraviolet irradiation output based on the number of occupants and environmental conditions to ensure effective sterilization and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ventilation amount is increased to improve air quality, then air sterilization effectiveness is improved, but power consumption increases
Solution Approach 1:
The ventilation device dynamically adjusts the ventilation amount and ultraviolet irradiation output based on real-time detection of occupancy and environmental conditions. The control unit modifies operational parameters continuously to maintain effective sterilization while minimizing energy consumption, rather than operating at fixed high levels.
Solution Approach 2:
The system changes operational parameters (ventilation amount and irradiation output) according to detected conditions such as number of occupants and environmental factors. This allows the device to adapt sterilization intensity and ventilation rate to actual needs, reducing energy consumption when high levels are not required while maintaining reliability when needed.
2Reliability
If coordinated control between ventilation and irradiation is implemented, then sterilization effectiveness is improved, but device complexity increases
Solution Approach 1:
The control unit integrates the control of both ventilation amount and ultraviolet irradiation output into a single coordinated system. By merging these control functions, the device achieves improved sterilization effectiveness through synchronized operation while avoiding the complexity of separate independent control systems.
Solution Approach 2:
The control unit serves multiple functions: detecting environmental conditions, determining occupancy, controlling ventilation amount, and regulating irradiation output. This multi-functionality reduces overall system complexity by consolidating control tasks into a single intelligent unit rather than requiring separate specialized controllers.
