Detachable Knife Sheath With Replaceable Adhesive Grinding Stones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing knife sheaths do not provide convenient access to grind stones for sharpening knives while being attached to a material belt, often requiring the belt to be undone for sheath removal and may detach unintentionally during use.
Innovation Solution
A detachable knife sheath with flexible clips and adhesive-mounted grind stones on its exterior walls allows for easy detachment and reattachment, enabling manual sharpening without unbuckling the belt, and uses replaceable abrasive surfaces bonded with adhesive layers for wear and tear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the knife sheath is attached to the material belt using a flexible clip, then the sheath remains secure during everyday movements, but the belt must be undone to remove the sheath for sharpening
Solution Approach 1:
The sheath is divided into separate components: the main body and the flexible clip attachment mechanism. This segmentation allows the sheath to be easily detached from the belt without unbuckling the entire belt, enabling access to the grind stones while maintaining secure attachment during normal use.
Solution Approach 2:
The flexible clip is designed to dynamically adjust between a locked state during normal wear (providing secure attachment) and an unlocked state during sharpening (allowing easy removal). The clip can be manually flexed to change its configuration, enabling transition between these states.
2Ease of operation
If the grind stones are permanently attached to the sheath, then they remain available for sharpening, but they cannot be replaced when worn out
Solution Approach 1:
The grind stones are extracted from permanent integration and mounted using removable adhesive layers. This allows the stones to be easily attached and detached from the sheath, enabling replacement when worn out while maintaining availability for sharpening during use.
Solution Approach 2:
The adhesive mounting system enables the grind stones to be discarded when worn and recovered/replaceable. The stones can be removed from the adhesive mounting and replaced with fresh stones, extending the usability of the sheath system.
3Reliability
If the flexible clip is made very secure, then unintentional detachment is prevented, but manual detachment for sharpening becomes difficult
Solution Approach 1:
The flexible clip is designed with dynamic characteristics that provide high retention force during normal use but allow controlled manual release. The clip's flexibility enables it to be deliberately manipulated to change its locked state, balancing security with ease of detachment when needed.
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
Facilitates convenient and secure sharpening of knives by allowing easy detachment and reattachment of the sheath, maintaining secure attachment to the belt and providing replaceable abrasive surfaces for continuous use.
Implementation Method 1
The first grind stone and/or second grind stone are bonded with the respective knife sheath walls by an adhesive layer contact creating a permanent bond or a non-permanent adhesive bonding such as heat sensitive adhesives and double-sided adhesive tapes and the like
Data Source
AI summary
The present invention provides a flexible clip detachment does not require the carrying belt to be undone for removal of the sheath and the adherend abrasive first grind stone and/or second grind stone are handily available for sharpening edges with the sheath instead of separate and possibly not available.
