Plate Connection Assembly With Integrated Threaded Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing connecting devices are complex and require multiple steps for assembly, such as thread cutting and nut setting, which increases material usage and installation space, leading to weight and packaging inefficiencies.
Innovation Solution
A connecting device design featuring a threaded screw with a thread profile that protrudes beyond the surfaces of the connecting sections, allowing for a simple attachment of components with a ratio of edge section surface width to thread nominal dimension between 0.1 and 3, and an engagement device with fixing projections and recesses to secure components against rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional connecting devices with nuts and multiple assembly steps are used, then reliable connection is achieved, but device complexity and assembly time increase
Solution Approach 1:
The patent combines the nut and the connecting element into a single integrated component. The connecting element includes an engagement portion that directly receives the screw thread and a connection portion that forms the structural link, eliminating the need for separate nuts and reducing assembly steps while maintaining reliable connection.
Solution Approach 2:
The connecting element is designed to perform multiple functions: it provides thread engagement, structural connection, and positioning all in one component. This multi-functional design reduces the number of parts needed and simplifies the overall assembly process while ensuring reliable connection.
2Strength
If traditional connecting devices with multiple components are used, then secure fastening is achieved, but material usage and weight increase
Solution Approach 1:
By merging the nut and connecting element into one integrated component, the patent reduces the total material used while maintaining fastening strength. The single connecting element is designed to provide both structural support and thread engagement, eliminating redundant materials from separate components.
3Reliability
If traditional connecting devices are used, then adequate connection is achieved, but installation space and packaging volume increase
Solution Approach 1:
The integration of multiple functions into a single connecting element significantly reduces the overall volume required for packaging and installation. The compact design of the connecting element with its engagement and connection portions in one component reduces space requirements compared to traditional multi-component assemblies.
4Ease of manufacture
If simple connecting elements are used, then assembly is simplified, but thread engagement and fastening capability are reduced
Solution Approach 1:
The connecting element is designed with different local geometries optimized for specific functions: the engagement portion has features optimized for thread reception and load bearing, while the connection portion has geometry optimized for structural integration. This localized optimization maintains high thread engagement strength while keeping the overall design simple for assembly.
