Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to assemble components, then the assembly is secure and reliable, but additional tools are required and production cost increases
Solution Approach 1:
The patent extracts the fastening function from traditional screws and implements it through an integrated elastic coupling structure. The elastic member (spring) is built into the coupling unit itself, eliminating the need for separate screws and tools, thereby reducing production cost while maintaining assembly reliability through the elastic retention mechanism.
Solution Approach 2:
The elastic coupling structure is self-contained and self-servicing. The elastic member automatically provides the necessary fastening force without requiring external tools or additional components. The coupling unit itself generates the retention force through its elastic deformation, making the assembly process simpler and more cost-effective.
2Strength
If screws are used to assemble components, then the connection is strong, but assembly time increases
Solution Approach 1:
The patent removes the time-consuming screw fastening step by extracting the fastening function and integrating it into the elastic coupling structure. The elastic member provides immediate connection strength upon engagement, eliminating the need for sequential screw tightening operations and significantly accelerating assembly speed.
Solution Approach 2:
The patent merges the fastening function with the coupling structure itself. The elastic member and coupling geometry are combined into a single integrated unit that provides both connection and retention functions simultaneously, allowing for faster assembly while maintaining strong connections.
3Strength
If screws are used for assembly, then components are securely fastened, but the display apparatus cannot be made thin
Solution Approach 1:
The patent extracts the thick screw thread structure and replaces it with a compact elastic coupling mechanism. The elastic member can be compressed within a minimal space to provide the necessary fastening strength, allowing the display apparatus to achieve a thin profile while maintaining secure component attachment.
Solution Approach 2:
The elastic member acts as a flexible element that can be compressed within a thin profile. This flexible component provides the necessary mechanical strength for fastening without requiring the thickness of traditional screw threads, enabling the overall apparatus to be made thinner.
4Reliability
If traditional coupling methods are used, then assembly is secure, but disassembly and maintenance become difficult
Solution Approach 1:
The patent employs a dynamic elastic coupling mechanism that can easily transition between coupled and uncoupled states. The elastic member allows for simple engagement by compression and easy disassembly by releasing the elastic force, making maintenance and repair straightforward while maintaining secure assembly during operation.
