Clip Fastening Device With Sliding Guide And Spring Thrust
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for applying and fastening clips to wooden slats are hindered by the difficulty in positioning and inserting tongues into grooves, and they often require complex mechanisms that are not suitable for narrow cavities, leading to inefficient and unsafe locking mechanisms.
Innovation Solution
A device with a sliding guide and spring thrust mechanism that aligns and propels clips into place, using a pneumatic nail gun to securely fasten them to a support structure, while jaws and stop elements ensure precise alignment and easy release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If complex mechanisms are used to position and insert clips, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The device is divided into separate functional modules: a magazine for holding multiple clips, a thrust mechanism for propelling clips forward, and a nail shooting mechanism for fastening. This segmentation allows each module to perform its function independently with simple structure, avoiding the need for a single complex positioning mechanism.
Solution Approach 2:
Clips are pre-loaded into the magazine in advance, and the thrust mechanism is pre-configured to propel them forward along the correct trajectory. This preliminary preparation eliminates the need for complex real-time positioning mechanisms during the actual fastening operation.
2Device complexity
If simple mechanisms are used for clip application, then device complexity is reduced, but positioning precision deteriorates
Solution Approach 1:
The thrust mechanism uses spring force to automatically propel clips forward along the guide, and the nail shooting mechanism automatically positions and drives nails through the clip heads. These self-acting mechanisms ensure precise insertion without requiring complex external positioning systems or manual adjustment.
3Ease of operation
If manual positioning is used for clip insertion, then ease of operation is improved, but productivity deteriorates
Solution Approach 1:
The magazine holds multiple clips in sequence, and the thrust mechanism continuously propels them forward one after another. The nail shooting mechanism is ready to fasten each clip immediately upon insertion. This continuous automated sequence eliminates manual repositioning between clips, maintaining high speed while requiring minimal operator intervention.
4Productivity
If automated mechanisms are used for fastening, then productivity is improved, but device complexity increases
Solution Approach 1:
The device combines the magazine, thrust mechanism, and nail shooting mechanism into a single integrated tool that performs multiple operations (clip feeding, positioning, and fastening) in one automated sequence. This merging achieves high productivity without requiring multiple separate complex devices or complex coordination between them.
