Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the microinverter is miniaturized to reduce size, then device compactness is improved, but assembly stability deteriorates
Solution Approach 1:
The locker mechanism incorporates elastic deformation capability where the locker body can flexibly deform during assembly and operation. This dynamic property allows the miniaturized structure to maintain stability by adapting to assembly variations and external impacts, resolving the contradiction between small size and assembly stability.
Solution Approach 2:
The invention changes the mechanical parameters of the locker structure by introducing elastic deformation characteristics. The locker body's ability to deform elastically alters the stiffness and flexibility parameters, enabling the miniaturized microinverter to maintain assembly stability despite its reduced size.
2Volume of moving object
If the device size is reduced, then portability is improved, but resistance to external impact deteriorates
Solution Approach 1:
The elastic deformation capability of the locker body provides dynamic shock absorption during transportation. When external impacts occur, the locker can flexibly deform to absorb impact energy, protecting the internal components of the miniaturized device while maintaining its compact size.
Solution Approach 2:
The locker mechanism is designed with inherent elastic properties that provide beforehand cushioning against external impacts. The elastic deformation capability is built into the structure in advance, creating a cushioning effect that protects the miniaturized device during transportation before actual impacts occur.
3Ease of manufacture
If simple assembly structures are used, then manufacturing ease is improved, but assembly stability deteriorates
Solution Approach 1:
The locker mechanism is designed as a self-service assembly structure where the elastic deformation capability enables automatic adjustment and self-locking during assembly. The locker body naturally deforms to fit with the mounting bracket without requiring complex external fastening mechanisms, achieving both ease of manufacture and assembly stability.
Solution Approach 2:
The elastic locker body acts as an intermediary element between the housing and mounting bracket. This intermediary component with deformation capability facilitates simple assembly while ensuring stable connection, bridging the gap between ease of manufacture and assembly stability in the miniaturized device.
