Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The screw locking method for assembling two plates is time-consuming and labor-intensive, particularly in disassembly, and is not well-suited for tool-less disassembly.
Innovation Solution
A fastener structure comprising a hollow sleeve, a rod body, and a hook assembly with an elastic component that allows for tool-less assembly and disassembly of two plates by moving the rod body between positions to engage and disengage the hook assembly with the second plate, utilizing structural interference for quick assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screw locking method is used to assemble two plates, then the connection is reliable and strong, but the assembly and disassembly process is time-consuming and labor-intensive
Solution Approach 1:
The fastening system is segmented into distinct functional components: a rod body for actuation, a hook assembly with hook component for engagement, and an elastic component for providing force. This segmentation allows each component to perform its specific function efficiently, enabling quick tool-less operation while maintaining reliable connection through the specialized hook mechanism
Solution Approach 2:
The fastener system incorporates dynamic elements including the rod body that can move between positions, the hook component that can rotate to engage or disengage from the positioning opening, and the elastic component that dynamically provides restoring force. This dynamic design enables rapid transition between fastened and released states without requiring tools or excessive time
2Strength
If screw locking method is used to assemble two plates, then the connection strength is sufficient, but the operation complexity and labor requirement increase
Solution Approach 1:
The elastic component is configured to automatically provide the necessary force for engagement and maintenance of the fastened state. When the rod body moves to the first position, the elastic component autonomously pushes the hook component to engage with the positioning opening, and when disengaged, automatically restores the hook component to its original position, eliminating the need for tools or complex manual operations
Solution Approach 2:
The system uses the elastic component's inherent restoring force to automatically maintain the fastened state and facilitate disengagement. The dynamic interaction between the rod body, hook component, and elastic component allows simple manual operation to control a self-regulating mechanism that ensures strong connection without requiring complex operational procedures

Function Achieved in This Case
Enables rapid and simple assembly and disassembly of plates without tools, with the elastic component facilitating easy detachment and reattachment through structural interference, providing a convenient and efficient connection method.
Implementation Method 1
the elastic component is elastically deformed, an elastic restoring force of the elastic component drives the hook component to restore

AI summary
A fastener structure is provided, including a hollow sleeve, a rod body, and a hook assembly. The hollow sleeve is assembled on a first plate, and the rod body is inserted into the hollow sleeve. The hook assembly is rotatably assembled on the first plate, and includes a hook component and an elastic component. The hook component is adapted for being fastened to a positioning opening portion of a second plate, where a first side of the rod body is adapted to lean against the hook component. A first end of the elastic component leans against the first plate, and a second end of the elastic component is fixed on the hook component.
