Innovation Solution
A fastener structure with an engaging portion, direction limiting portion, and anti-rotation portion that allows for quick and simple arrangement of a second object on a first object, using various assembly methods such as rivet, expansion, weld, or elastic fastening, and an assembly method involving tool-assisted placement or dropping for efficient positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional screw and sleeve fixing member is used to connect two parallel plates, then the connection strength and reliability are improved, but the assembly and removal processes become complicated and time-consuming due to requiring tools
Solution Approach 1:
The fastener structure enables self-service assembly and disassembly through its integrated design. The engaging portion with direction limiting portion and anti-rotation portion allows the fastener to be assembled by simply inserting it into the first object, where it automatically generates anti-rotation effect and limits movement direction. No external tools or complex operations are needed, as the structure itself performs the assembly function.
Solution Approach 2:
The fastener structure is divided into distinct functional segments: an engaging portion for connecting to the second object, a direction limiting portion for constraining movement, and an anti-rotation portion for preventing rotation. This segmentation allows each component to perform its specific function independently, enabling simple tool-free assembly while maintaining reliable connection.
2Reliability
If a conventional screw and sleeve fixing member is used to connect two parallel plates, then the connection strength and reliability are improved, but the device complexity increases due to requiring multiple components and tools
Solution Approach 1:
The invention merges the functions of engaging, direction limiting, and anti-rotation into a single integrated fastener structure. Instead of using separate screw, sleeve, and locking components, all functions are combined in one piece that can be assembled without tools. This merging reduces device complexity while maintaining connection reliability through the coordinated action of its integrated portions.
Solution Approach 2:
The fastener structure serves multiple functions simultaneously: it engages with the second object, limits movement direction, and prevents rotation. This multi-functionality is achieved within a single component design, eliminating the need for multiple separate parts and tools, thereby reducing overall device complexity while ensuring reliable connection.
3Strength
If a conventional screw and sleeve fixing member is used to connect two parallel plates, then the connection strength is improved, but the ease of operation deteriorates due to requiring tools and complex assembly steps
Solution Approach 1:
The fastener structure enables self-service assembly and disassembly through its integrated design. The engaging portion with direction limiting portion and anti-rotation portion allows the fastener to be assembled by simply inserting it into the first object, where it automatically generates anti-rotation effect and limits movement direction. No external tools or complex operations are needed, as the structure itself performs the assembly function.
4Manufacturing precision
If a tool-assisted assembly method is used for conventional fasteners, then the positioning precision is improved, but the productivity decreases due to time-consuming assembly and removal processes
Solution Approach 1:
The fastener structure incorporates preliminary action through its pre-designed engaging portion, direction limiting portion, and anti-rotation portion. These features are built into the structure beforehand, allowing it to automatically achieve proper positioning and orientation upon insertion. The direction limiting portion pre-defines the movement direction, and the anti-rotation portion pre-establishes the anti-rotation effect, eliminating the need for tool-assisted positioning during assembly.
Solution Approach 2:
The fastener structure enables self-service assembly and disassembly through its integrated design. The engaging portion with direction limiting portion and anti-rotation portion allows the fastener to be assembled by simply inserting it into the first object, where it automatically generates anti-rotation effect and limits movement direction. No external tools or complex operations are needed, as the structure itself performs the assembly function.
