Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting structures, such as screw connections, face inefficiencies in processing time due to the need for multi-threaded fastening, which is time-consuming and affects strength, and storage racks with bolt connections are cumbersome and costly, requiring more beams and reducing assembly efficiency.
Innovation Solution
A connecting structure featuring a fastener with a threaded connecting hole and a combined connecting hole, including an insertion hole and a slide slot, where the fastener's pitch matches the thickness of the connecting member, allowing for efficient assembly and disassembly without the need for extensive threading, and a reinforcing rib on beams for uniform force-bearing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multi-threaded fastening is used to ensure connection strength, then connection strength is improved, but processing time increases significantly
Solution Approach 1:
The patent applies partial threading by creating only a single-threaded connecting hole instead of multi-threaded holes. This single threaded hole provides sufficient connection strength while dramatically reducing the time required for tapping and fastening operations, eliminating the need for multiple threads and associated processing time
2Strength
If bolt connections are used for storage racks, then connection strength is improved, but device complexity and cost increase
Solution Approach 1:
The patent merges the functions of multiple components into a single integrated connecting piece. The connecting piece combines the threaded hole, insertion hole, and slide slot into one element, eliminating the need for separate bolts, nuts, and multiple holes, thereby simplifying the storage rack structure while maintaining connection strength
Solution Approach 2:
The connecting piece serves multiple functions simultaneously: it provides threaded fastening through the threaded connecting hole, enables insertion through the insertion hole, and allows positioning through the slide slot. This multi-functionality reduces the number of separate components needed in the storage rack structure
3Ease of operation
If sufficient space is left for screwdriver operation, then ease of operation is improved, but the connecting structure becomes more complex
Solution Approach 1:
The patent introduces a slide slot that extends in a direction perpendicular to the threaded connecting hole axis. This dimensional extension provides the necessary space for screwdriver operation and finger access without increasing the overall size of the connecting head in the primary fastening direction, thus maintaining a compact structure while improving operability

AI summary
The present invention discloses a connecting structure, a connecting method and an article containing the connecting structure. The connecting structure includes a fastener, a first connecting member adjacent to the trailing end of the fastener and a second connecting member away from the trailing end of the fastener. The second connecting member is provided with a threaded connecting hole, which in the axial direction thereof is provided with thread matching with the form of thread of the fastener and having a central angle of at least 180 degrees. The first connecting member is provided with a connecting hole, and the fastener connects the two connecting members through the threaded connecting hole and the connecting hole. The connecting method achieves quick connecting with the connecting hole of the first connecting member by preloading the fastener to the threaded connecting hole, without being affected by the assembly space. The connecting structure and the connecting method can be used in a variety of articles. The thickness of the threaded connecting hole is equal to the pitch of the fastener. The form of thread of the threaded connecting hole is fitted with the thread of the fastener by only one turn, which during processing can be made directly in the form of stamping, resulting in a simple processing and improving the processing efficiency.
