Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed working modes and separate control gears are used, then the device structure is simple, but the adaptability and flexibility are limited
Solution Approach 1:
The patent merges the control of airflow speed and temperature into a single integrated control system. The control board receives signals from the stepless adjustment assembly and simultaneously adjusts both the negative pressure assembly and heating elements, eliminating the need for separate control gears and enabling flexible combination of different parameters.
Solution Approach 2:
The patent implements dynamic adjustment capabilities through a stepless adjustment assembly that allows continuous variation of operating parameters. The system can dynamically switch between different working modes (normal temperature mode, hot air mode, variable temperature mode) and continuously adjust airflow speed and temperature within each mode, providing high adaptability.
2Adaptability or versatility
If predetermined working modes are used, then the device operation is simple, but the range of usability is limited
Solution Approach 1:
The patent enables continuous parameter changes through the stepless adjustment assembly, allowing users to independently adjust airflow speed and temperature within wide ranges. The system supports variable temperature adjustment from low to high temperatures and variable speed adjustment, providing extensive usability range while maintaining ease of operation through a unified control interface.
3Adaptability or versatility
If separate control of airflow gear and temperature gear is used, then the control system is simple, but the available working modes are limited
Solution Approach 1:
The control board serves multiple functions by simultaneously controlling the negative pressure assembly and heating elements based on signals from the stepless adjustment assembly. This multi-functional control system enables various working modes (normal temperature mode, hot air mode, variable temperature mode) while using a single integrated control structure rather than separate control systems.
