Throwing Knife Removable Guard for Barrier Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing throwing knives pose a safety hazard when thrown at targets with barriers that have holes, as their slim profile allows them to pass through and potentially harm unintended targets or property.
Innovation Solution
A throwing knife design featuring a removable guard that slides over the blade and secures with fasteners, preventing the knife from passing through holes in barriers by resting on notches along the blade.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a slim-profile throwing knife is used, then throwing accuracy and spin control are improved, but safety is worsened due to potential passage through barrier holes
Solution Approach 1:
The guard is designed as a removable component that can be selectively attached or detached from the knife blade. This dynamic configuration allows the user to adapt the knife's profile thickness according to the specific throwing scenario - using the slim profile for accuracy when barriers are not present, and adding the guard for safety when barriers with holes are present.
Solution Approach 2:
The knife system is divided into separate components: the blade and the guard. The guard is a distinct element that can be independently attached to the blade via fasteners. This segmentation allows the safety feature to be added or removed without affecting the core throwing functionality of the blade itself.
2Object-affected harmful factors
If a guard is added to the throwing knife, then safety is improved by preventing passage through holes, but device complexity increases
Solution Approach 1:
The guard is designed as a separate, removable component rather than an integrated part of the blade. This segmentation allows the safety feature to be added only when needed, keeping the basic knife structure simple for routine use while providing enhanced safety when required.
Solution Approach 2:
The guard's removability creates a dynamic system where the complexity can be adjusted based on operational requirements. The simple blade design is maintained for normal throwing activities, while the guard can be attached to provide additional safety features when the specific situation demands it.
3Adaptability or versatility
If a removable guard is used, then adaptability is improved for different barrier conditions, but ease of operation is worsened due to attachment and removal steps
Solution Approach 1:
The guard is designed with fastening and unfastening mechanisms that enable quick attachment and removal. This dynamic design allows users to rapidly configure the knife for different throwing scenarios without time-consuming operations, maintaining ease of use while providing adaptability.
Solution Approach 2:
The guard and fasteners are pre-configured as a complete assembly that can be quickly attached to the blade. The preliminary preparation of these components ensures that when adaptability is needed, the user can rapidly deploy the guard without complex assembly steps.

AI summary
A knife adapted for competitive knife-throwing that includes removable guards that can be added in the case that the knife throwing is directed toward a target with holes therethrough. The removable guards can be put in place prior to throwing at such a target to provide a stop against the hazard of the knife potentially moving through a hole and hitting an unintended target.
