Pressable Locating Mechanism for Tool-Free Plate Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fastening devices using screws or pins are inconvenient to operate, prone to losing fasteners, and result in unstable assemblies, making it difficult to align and fasten two plates effectively.
Innovation Solution
A pressable locating device with a driving mechanism featuring a shaft, restraining rod, and restraining member of different diameters, along with a pressing unit and elastic parts, allows for quick alignment and fastening of two plates by moving the pressing unit vertically to engage the locating members with the restraining rod.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws or pins are used to fasten and locate plates, then the plates can be securely fastened, but the operation becomes inconvenient and fasteners may be lost
Solution Approach 1:
The pressing unit integrates multiple functions into a single component: it serves as both the fastening mechanism and the locating mechanism. The pressing member combines the pressing function with locating members that have guiding grooves, eliminating the need for separate screws or pins and their associated hand tools.
Solution Approach 2:
The pressing unit is designed to be self-contained, with the elastic member providing automatic return functionality. The locating members with guiding grooves automatically guide the pressing member during insertion and removal, eliminating the need for external tools or backup fasteners.
2Reliability
If multiple screws or pins are used for assembly, then the plates can be fastened, but it becomes difficult to find and manage the fasteners
Solution Approach 1:
Multiple fastening and locating functions are merged into the single pressing unit. The locating members are integrated into the pressing member itself, and the elastic member provides automatic return, eliminating the need to manage multiple separate fasteners.
Solution Approach 2:
The pressing unit serves multiple functions simultaneously: fastening, locating, guiding, and automatic return. This multi-functional design replaces multiple specialized fasteners with a single universal component.
3Reliability
If conventional fastening devices are used, then plates can be connected, but alignment precision is difficult to achieve
Solution Approach 1:
The locating members with guiding grooves perform preliminary alignment before the actual fastening occurs. The guiding grooves pre-position the pressing member correctly, ensuring accurate alignment is achieved before the pressing force is applied.
Solution Approach 2:
The invention replaces the manual alignment process with a mechanical guiding system. The guiding grooves automatically guide the pressing member into the correct position, substituting operator skill with a reliable mechanical guidance mechanism.
