Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws are used to fasten storage components, then the storage component can be securely fastened in the chassis, but the assembly process requires specific tools and increases assembly time and labor cost
Solution Approach 1:
The patent replaces the traditional screw-fastening mechanical system with a snap-fit plastic fastening system. The fastening component includes a body with a receiving cavity that receives a protrusion from the storage component, and an elastic element that provides snap-fit retention. This substitution eliminates the need for screws and screwdrivers, enabling tool-free assembly while maintaining secure fastening.
Solution Approach 2:
The fastening system is divided into separate functional components: a fastening component with a receiving cavity, a storage component with a protrusion, and an elastic element. This segmentation allows each component to be optimized independently and enables simple, tool-free assembly by simply inserting the protrusion into the receiving cavity and pressing down.
2Reliability
If screws are used to fasten storage components, then the storage component can be securely fastened, but the process becomes complex and time-consuming
Solution Approach 1:
The patent replaces the complex screw-fastening system with a simple snap-fit mechanism. The fastening component includes a receiving cavity that receives a protrusion from the storage component, and an elastic element that provides snap-fit retention. This substitution eliminates the need for screws, screwdrivers, and associated threading operations, dramatically simplifying the fastening process.
Solution Approach 2:
The snap-fit fastening mechanism is self-aligning and self-securing. The protrusion automatically engages with the receiving cavity when pressed together, and the elastic element automatically provides retention without requiring tools or complex operations. The system serves itself by using the elastic deformation of the plastic material to create the fastening action.
3Reliability
If screws are used for fastening, then storage components can be secured, but users experience inconvenience due to tool requirements and risk of losing screws
Solution Approach 1:
The patent replaces the screw-fastening system with a tool-free snap-fit system. The fastening component includes a receiving cavity that receives a protrusion from the storage component, and an elastic element that provides snap-fit retention. This substitution eliminates the need for users to possess or use screwdrivers, and eliminates the risk of losing screws, greatly improving user convenience.
Solution Approach 2:
The snap-fit mechanism requires no external tools and cannot be lost like screws. The protrusion and receiving cavity design ensures that the fastening component remains attached to the storage component during assembly and disassembly operations, eliminating the inconvenience of tool requirements and component loss.
4Reliability
If screws are used to fasten storage components, then the storage component can be secured, but assembly and disassembly becomes time-consuming
Solution Approach 1:
The patent replaces the time-consuming screw-fastening process with a rapid snap-fit process. The fastening component includes a receiving cavity that receives a protrusion from the storage component, and an elastic element that provides snap-fit retention. Assembly is achieved by simply inserting the protrusion into the receiving cavity and pressing down, while disassembly is achieved by pressing upward, eliminating the need for threading and unscrewing operations.
Solution Approach 2:
The snap-fit mechanism utilizes dynamic elastic deformation of the plastic material to achieve rapid engagement and disengagement. The elastic element can be compressed during assembly to allow the protrusion to enter the receiving cavity, then springs back to provide retention. During disassembly, upward pressure compresses the elastic element again, allowing easy release, enabling rapid assembly and disassembly operations.
