Tactical Glove Strap-Actuated Zipper Seal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tactical gloves face challenges in maintaining a leak-tight seal with tactical jackets, particularly in rain conditions, due to fluid penetration through sleeves, and existing designs are either cumbersome or difficult to put on quickly.
Innovation Solution
A tactical glove with a strap-based closure system that automatically operates a zipper on the sheath, allowing for rapid and easy opening and closing, eliminating the need for manual zipper operation and providing a wrist support for enhanced protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cuffed glove design is used to cover the forearm completely, then protection against environmental conditions is improved, but fluids can penetrate into the glove from above via the tactical jacket sleeves
Solution Approach 1:
The glove is nested within the tactical jacket sleeve, with the cuff inserted into the sleeve interior. This nesting arrangement allows the glove to be protected by the jacket structure while maintaining fluid-tight sealing through the combination of glove material and jacket sleeve.
Solution Approach 2:
The cuff is pre-configured with specific structural features (such as reinforced edges, sealing surfaces, or integrated fastening elements) that enable it to form a fluid-tight joint with the jacket sleeve before actual use. This preliminary preparation ensures that when the glove is put on, the sealing interface is already optimized to prevent fluid penetration.
2Object-affected harmful factors
If a knitted cuff is tucked under the tactical jacket and closed with a zipper, then fluid penetration is prevented, but putting on the glove becomes difficult and time-consuming
Solution Approach 1:
The closure system is segmented into multiple independent components: a zipper for fluid-tight sealing and a strap with mechanical closure means for rapid fastening. This segmentation allows the user to first secure the zipper for protection, then quickly fasten the strap without manipulating the zipper, significantly reducing the time to don the glove.
Solution Approach 2:
The strap with mechanical closure means acts as an intermediary element that simplifies the donning process. Instead of requiring precise manual manipulation of zipper teeth and slider, the strap provides a larger, more accessible mechanical closure that can be quickly fastened with one hand, while the zipper remains in place to maintain fluid-tight sealing.
3Reliability
If a manual zipper operation is required, then fluid-tight sealing is achieved, but the closure process becomes complex and slow
Solution Approach 1:
The zipper and strap closure systems are merged into a coordinated arrangement where the strap with mechanical closure means works in conjunction with the zipper. The strap provides ease of operation by offering a simple mechanical fastening mechanism, while the zipper maintains fluid-tight sealing. Both systems work together rather than in opposition, with the strap serving as the primary closure and the zipper providing secondary sealing.

AI summary
A tactical glove (1) with a glove body (2), glove fingers (3a to 3e) and a sheath (4) adjoining the glove body (2). A closure system is provided in the form of a strap (5). The strap is fastened at one end to the tactical glove (1) and has a mechanical closure (6) that is moved onto a corresponding mechanical closure (7) by a closing movement of the strap (5) in order to constrict the sheath (4), via which a mechanical closure is formed. On the sheath (4) a zipper (8) is provided, the slider (9) of which is joined to the strap (5) by a coupling such that when a closing movement of the strap (5) is performed, the zipper (8) closes. The strap (5) forms a wrist support.
