Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thermal sensors and position and motion control are added to detect and adjust airflow, then temperature homogenization and occupant comfort are improved, but device complexity increases
Solution Approach 1:
The system employs thermal sensors to continuously monitor temperature distribution within the vehicle cabin and feeds this information back to the position and motion control mechanism. This feedback loop enables automatic adjustment of motorized vent positions and louver angles to achieve optimal temperature homogenization without manual intervention, resolving the contradiction by automating the control process while maintaining system reliability.
Solution Approach 2:
The position and motion control mechanism serves multiple functions: it controls motorized vent positioning, adjusts louver angles, and coordinates airflow distribution across multiple vents simultaneously. By consolidating these control functions into a single multi-functional system, the patent reduces overall device complexity while achieving improved temperature homogenization through coordinated airflow management.
