Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If louver boards are fixed by hinge pin screws and rivet nuts on the ring beam, then the louver boards can be securely mounted, but the assembly process requires high production precision and results in accumulated errors
Solution Approach 1:
The patent divides the mounting system into modular components: louver boards, connecting pieces (fixing seats), and the ring beam. Each component has standardized interfaces with slots and insertion portions that can be assembled independently without requiring precise hole alignment across the entire structure, thereby eliminating accumulated errors.
Solution Approach 2:
The patent changes the connection parameter from fixed-point screw fastening to slot-based insertion fit. The slots provide adjustment range and tolerance accommodation, allowing components to be connected without requiring high precision hole spacing, thus resolving the accumulated error problem.
2Reliability
If rivet nuts are assembled on each hole and louver board rotating parts are assembled by hinge pin screws, then secure mounting is achieved, but the process is tedious and results in high labor cost
Solution Approach 1:
The patent combines multiple fastening functions into a single integrated connecting piece (fixing seat) that simultaneously provides slot-based positioning, snap-fit connection via back teeth and grooves, and support for the louver board rotating part. This eliminates the need for separate rivet nuts and hinge pin screws, dramatically simplifying the assembly process.
Solution Approach 2:
The snap-fit connection mechanism with back teeth and grooves enables self-aligning and self-locking during assembly. The insertion portions fit into slots and the back teeth snap into grooves automatically, eliminating the need for manual screw fastening and reducing labor requirements.
3Reliability
If hinge pin screws are used to mount louver board rotating parts, then the parts can be securely fixed, but the screws are at risk of falling off after the louver boards have rotated many times
Solution Approach 1:
The patent designs the connecting piece with built-in wear compensation features. The slot-based connection allows for movement and adjustment that compensates for wear and stress accumulation over time. The snap-fit mechanism with elastic deformation capability absorbs stress cycles, preventing the connection failure that occurs with rigid screw fastening after repeated rotations.
Solution Approach 2:
The patent transitions from static screw fastening to a dynamic snap-fit connection that can accommodate movement and stress. The back teeth and grooves design allows for controlled movement and self-adjustment during operation, maintaining connection integrity over time whereas fixed screws become loose and fail.
