Latching Closure for Hand-Held Setting Tool Magazine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hand-held setting tools face issues with dirt entry and complex magazine attachment due to the pivotable arrangement of the magazine, leading to transport problems and potential component breakage.
Innovation Solution
A setting tool with a latching closure mechanism featuring a snap-in connection between the magazine and housing, which automatically snaps into place for easy attachment and creates a tight seal, along with a pivot bearing allowing the magazine to be pivoted flush without collision, and an elastic slide for enhanced detachment and reattachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the magazine is arranged in a pivotable manner on the housing, then the magazine can be detached and reattached, but dirt can enter the magazine leading to transport problems
Solution Approach 1:
A closure element is introduced as an intermediary component between the magazine opening and the housing. This closure element can be positioned to cover the magazine opening when the magazine is detached, preventing dirt entry while still allowing easy attachment and detachment of the magazine through the pivotable connection
Solution Approach 2:
The closure element acts as a flexible barrier that can move with the magazine during attachment and detachment while maintaining the seal. This flexible closure prevents dirt from entering the magazine opening during transport when the magazine is detached
2Adaptability or versatility
If the magazine is pivotably attached to the housing, then the magazine can be removed, but the attachment mechanism becomes complicated
Solution Approach 1:
The attachment mechanism is segmented into distinct functional elements: a pivot connection for rotational movement, a latching mechanism for secure attachment, and a closure element for sealing. This segmentation allows each component to perform its specific function independently, simplifying the overall design while maintaining removability
Solution Approach 2:
Instead of complicating the pivotable attachment to achieve secure fastening, the invention uses a simple pivot connection combined with a latch that engages automatically. The complexity is inverted by making the attachment simple (pivot) and adding a separate simple locking mechanism (latch) that engages naturally
3Object-affected harmful factors
If the magazine is securely attached to prevent dirt entry, then the seal is tight, but the magazine cannot be easily removed in case of accidental drop
Solution Approach 1:
The attachment system is designed with dynamic characteristics where the latch can engage automatically during normal operation to provide tight sealing, but can be easily released when needed. The pivotable connection allows natural movement during accidental drops that can automatically disengage the latch, enabling emergency removal without manual intervention
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
The solution ensures a secure, dirt-proof magazine attachment that simplifies the attachment process, reduces the risk of component breakage, and allows for easy removal and reattachment, enhancing the tool's operational reliability and user convenience.
