Reversible Ring Mesh Glove Fastening Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protective gloves with metal ring mesh fastening straps are cumbersome to switch between left and right hand use, as the fastening strap must be removed and reinserted in the opposite direction, compromising ease of use and safety.
Innovation Solution
The protective glove features offset passage openings in the receiving channel or loops, allowing the fastening strap to be guided outward while maintaining puncture protection, enabling easy hand switching without compromising safety or mobility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the fastening strap is firmly chained to the glove with conventional snap fasteners, then the fastening security is improved, but the ease of switching between hands deteriorates as the strap must be removed and reinserted in the opposite direction
Solution Approach 1:
The receiving channel is divided into multiple reception areas with snap fasteners positioned at different locations. The fastening strap can be inserted through passage openings and secured at different positions along the channel, allowing flexible configuration for left or right hand use without removing the strap from the glove.
Solution Approach 2:
The fastening system allows dynamic adjustment of the strap position within the receiving channel. The strap can be fastened at different snap fastener receptacles along the channel, enabling adaptation to different hand orientations while maintaining secure fastening.
2Ease of operation
If passage openings are provided in the receiving channel or loops, then the ease of switching between hands is improved, but the puncture protection deteriorates as the openings could potentially allow knife or stickleback intrusion
Solution Approach 1:
The passage openings are strategically positioned in specific locations within the receiving channel or loops, and their size and shape are optimized to allow the fastening strap to pass through while minimizing the risk of knife or stickleback intrusion. The openings are localized and controlled rather than large and exposed.
Solution Approach 2:
The passage openings are nested within the structure of the receiving channel or loops, with the metal ring mesh providing surrounding protection. The openings are integrated into the existing structure rather than being separate vulnerabilities, maintaining the overall protective integrity of the glove.
3Object-affected harmful factors
If the glove is completely closed for safety, then the puncture protection is improved, but the stretchability deteriorates as the glove may not be able to stretch properly when completely closed
Solution Approach 1:
The passage openings are positioned in specific locations that allow the glove to maintain its closed structure for puncture protection while providing localized flexibility for stretching. The openings are strategically placed to permit stretchability in the transition area to the user's arm without compromising the overall closed protection.

AI summary
The glove has a rotatable metallic ring mesh with a closing strip (15) partially received in a receiving channel (10) or in a back strap and fixing the glove at a body of a carrier. An opening pushes the strip on an outer side of the glove and is formed by multiple passage openings (A, B) that are spaced from each other in a circumference direction of the glove. The passage openings are shifted around a distance to each other in the direction and provided in an area of the channel or strap. A base of the passage openings is covered by an opposite side of the channel or strap.
