Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional blower systems are used, then the system structure is simple, but the system occupies excessive space and generates insufficient airflow
Solution Approach 1:
The patent combines the blower and impeller into a single integrated system where the blower fan and impeller share a common housing and operational space. This merging of functions allows the system to achieve higher airflow volume and pressure while occupying less space, as the two components work together in a unified configuration rather than as separate units.
2Productivity
If conventional blower systems are used, then the system occupies less space, but the airflow pressure and volume are insufficient
Solution Approach 1:
The integrated blower-impeller system merges two functional components into one compact unit, achieving both high airflow pressure and reduced volume. The blower fan pressurizes air while the impeller accelerates and directs it, with both actions occurring within the same housing space, thereby increasing productivity without proportionally increasing system volume.
Solution Approach 2:
The patent utilizes a curvilinear impeller outlet design that optimizes airflow in multiple directions, creating wider airflow directional spread. This dimensional optimization of the outlet geometry allows the compact system to achieve high airflow pressure and volume by efficiently utilizing three-dimensional space within the housing.
3Volume of moving object
If compact information handling systems are designed, then space occupancy is reduced, but heat dissipation becomes inadequate
Solution Approach 1:
The integrated blower-impeller system provides enhanced cooling capability in a compact form factor. By combining the pressurization function of the blower with the acceleration function of the impeller, the system generates sufficient airflow volume and pressure to effectively remove heat from compact information handling systems, addressing the heat dissipation challenge without increasing system volume.
