Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional snapping devices in rivet guns require a wrench for disassembly and cleaning, making it difficult for users to clean metal scraps without the essential tool.
Innovation Solution
A quick-disassemble snapping device with a front sleeve, rear sleeve, snapping assembly, and retaining assembly, featuring positioning recesses, inner and outer threads, and a compression spring-based locking mechanism that allows for tool-free disassembly and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the front sleeve and rear sleeve are tightly engaged with threads to avoid loosening, then the structural stability is improved, but the ease of disassembly deteriorates requiring a wrench
Solution Approach 1:
The retaining assembly is segmented into a locking ring with engaging teeth, a stop ring, and an outer spring. The locking ring's teeth engage with positioning recesses in the front sleeve to provide stability, while the segmented design allows the locking ring to be independently manipulated for quick release without affecting the threaded connection between sleeves.
Solution Approach 2:
The locking ring acts as an intermediary mechanism between the threaded connection and the user. It provides the stabilizing engagement with positioning recesses while simultaneously serving as a quick-release interface that can be operated by hand, mediating between the need for tight engagement and easy disassembly.
2Reliability
If a wrench is required for disassembling the snapping device, then the structural stability during assembly is improved, but the ease of maintenance deteriorates
Solution Approach 1:
The locking ring with engaging teeth provides self-locking functionality during assembly, ensuring reliable engagement without requiring external tools. During maintenance, the same locking ring structure enables self-service disassembly by allowing users to manually operate the release mechanism without needing a wrench.
3Ease of manufacture
If the snapping device is designed as a integrated unit, then the manufacturing simplicity is improved, but the ease of cleaning deteriorates
Solution Approach 1:
The snapping device is segmented into the front sleeve, rear sleeve, snapping assembly, and retaining assembly. This segmentation allows the cleaning-related components (front and rear sleeves) to be easily separated for cleaning metal scraps, while the threaded connection and locking mechanism remain simple for manufacturing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy disassembly and cleaning of the snapping device without the need for a wrench, maintaining a stable structure during operation and facilitating maintenance.
Implementation Method 1
The outer spring is a compression spring, is mounted around the rear sleeve, and has two opposite ends respectively abutting against the locking ring and the stop ring

AI summary
A quick-disassemble snapping device of a rivet gun has a front sleeve, a rear sleeve, a snapping assembly, and a retaining assembly. The front sleeve has multiple positioning recesses. The rear sleeve is coaxially connected with the front sleeve and has at least one mounting recess. The snapping assembly is mounted in the front sleeve and the rear sleeve. The retaining assembly has a locking ring. The locking ring is mounted around the rear sleeve and has at least one engaging tooth mounted through the at least one mounting recess of the rear sleeve and engaging in at least one of the positioning recesses of the front sleeve. The quick-disassemble snapping device can be used in a pneumatic, manual, or electric rivet gun and has a stable structure. No tool is needed for disassembling the snapping device and the snapping device can be easily disassembled to be cleaned.
