Interchangeable Tool Carabiner Gate Assembly for Belt Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool carabiners require replacement of the entire device for changing the gate mechanism, which is unsafe and impractical due to non-removable pins, and lack the ability to individually replace snap fasteners without disposing of other components.
Innovation Solution
A tool carabiner design with a detachable interchangeable gate assembly and snap fasteners, allowing independent replacement of the gate and snap fasteners without safety concerns, using a rail system or screw connections for secure attachment to a belt.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the gate is permanently hinged to the main part by a non-removable pin, then the carabiner structure is simple and robust, but the gate cannot be replaced individually and manual pin removal creates safety risks
Solution Approach 1:
The gate assembly is segmented into separable components: the gate itself, the connecting piece, and the attachment mechanism to the main part. This allows the gate to be replaced independently by removing only the connecting piece from the main part, without affecting the gate's internal pin structure. The segmentation enables individual component replacement while maintaining overall structural integrity.
Solution Approach 2:
The connecting piece is extracted as a separate intermediate component between the gate and the main part. This connecting piece can be detached from the main part while the gate remains attached to the connecting piece via its original pin. This extraction allows gate replacement without manipulating the gate's internal pin, eliminating safety risks while enabling adaptability.
2Adaptability or versatility
If the entire tool carabiner must be replaced to change the gate mechanism, then component reliability is maintained, but material waste increases and cost rises
Solution Approach 1:
The snap fastener system is segmented into the main part with strap mounting means and the separate connecting piece with gate. This segmentation allows the main part to be retained and reused when only the gate needs replacement, significantly reducing material waste. The connecting piece serves as the interchangeable element that can be removed and replaced independently.
Solution Approach 2:
When replacing the gate, only the connecting piece is discarded or replaced, while the main part is recovered and reused. This selective replacement approach minimizes material loss and reduces waste compared to replacing the entire carabiner assembly. The main part's strap mounting means and structural components are preserved for continued use.
3Ease of operation
If the gate and strap mounting means are integrated in a single piece, then manufacturing is simpler, but the gate cannot be replaced independently of the strap attachment
Solution Approach 1:
The carabiner is segmented into distinct functional modules: the main part with strap mounting means, and the connecting piece with gate. This segmentation enables independent replacement of the gate assembly from the strap attachment system. The connecting piece acts as an interface that can be detached from the main part while leaving the strap mounting means intact and reusable.
Solution Approach 2:
The main part is designed with universal strap mounting means that can accommodate different gate configurations. The connecting piece serves multiple functions: attaching the gate to the main part and providing a standardized interface for replacement. This multi-functionality allows the main part to work with different gate types while maintaining ease of manufacture through standardized components.
