Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple building units (heating systems, air conditioning systems, humidifiers, air filters) are used to maintain indoor climate parameters, then the indoor climate control capability is improved, but the device complexity and susceptibility to failures increase
Solution Approach 1:
The patent extracts and eliminates unnecessary building units from the system. By using only ventilation flaps controlled by a simple algorithm, it removes heating systems, air conditioning systems, humidifiers, and air filters while maintaining indoor climate control through natural ventilation alone.
Solution Approach 2:
The ventilation flap system performs multiple functions simultaneously - it controls temperature, humidity, and air quality through a single device. The flap's position adjustment enables the system to handle various climate conditions without requiring specialized equipment for each parameter.
2Adaptability or versatility
If multiple building units are used to maintain indoor climate parameters, then the indoor climate control capability is improved, but the maintenance effort and costs increase
Solution Approach 1:
The patent removes multiple building units that require maintenance (heating systems, air conditioning systems, humidifiers, air filters), leaving only the ventilation flap system which has minimal maintenance requirements and no moving parts that wear out.
3Adaptability or versatility
If a central computing or control unit coordinates multiple building units, then the indoor climate control is improved, but the computational load and error susceptibility increase
Solution Approach 1:
The patent extracts and removes the central computing or control unit from the system. Instead of using complex algorithms and coordinate control, it employs a simple rule-based approach where ventilation flaps are automatically controlled by basic sensor feedback, eliminating the need for heavy computational processing.
Solution Approach 2:
The system uses automatic feedback control where sensors detect indoor air parameters and directly control the ventilation flaps without human intervention or complex computation. The system self-regulates by comparing measured values with target values and adjusting flap positions accordingly.
4Reliability
If heating systems, air conditioning systems, humidifiers, and air filters are used, then the indoor climate parameters are maintained, but the energy consumption increases
Solution Approach 1:
The patent removes energy-intensive building units (heating systems, air conditioning systems, humidifiers, air filters) and replaces them with a passive ventilation system that uses natural air flow, significantly reducing energy consumption while maintaining indoor climate parameters.
Solution Approach 2:
The system changes the operational parameters by using variable ventilation flap positions to control air flow rates, allowing the system to adapt to different outdoor conditions and maintain optimal indoor climate without energy-intensive active heating or cooling.
