Training Edged Weapon With Inked Felt Marking Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current edged weapon training devices lack a mechanism to visibly indicate contact with a target during training, making it difficult to evaluate the effectiveness of stabbing and slashing techniques.
Innovation Solution
An edged weapon training device with a handle and a flexible blade featuring an inked felt marking device that leaves marks on an opponent during training, allowing for clear evaluation of technique effectiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional dummy knives are used for training, then training safety is improved, but the ability to detect contact effectiveness deteriorates
Solution Approach 1:
The patent applies color change principle by incorporating inked felt or other marking substances on the blade surface that transfer color to the target upon contact. This allows visual detection of effective contact while maintaining the safety of dummy knives, as the marking mechanism does not involve sharp edges or harmful components.
Solution Approach 2:
The patent uses an intermediary marking substance (inked felt, paint, or other transferable material) between the training knife and target. This intermediary allows contact detection without requiring the knife itself to have detectable physical properties, thus maintaining safety while enabling effective contact verification.
2Measurement precision
If marking devices are added to the blade, then contact detection capability is improved, but device complexity increases
Solution Approach 1:
The patent applies local quality principle by placing marking devices only at specific contact points on the blade (edge, point, or selected surfaces) rather than making the entire blade complex. This allows contact detection functionality to be added with minimal increase in overall device complexity, as only localized areas require marking capability.
Solution Approach 2:
The patent employs simple, inexpensive marking materials such as inked felt, paint, or transferable dyes that can be easily reapplied or replaced. These marking devices are kept simple and disposable rather than complex and permanent, minimizing device complexity while maintaining effective contact detection throughout the training process.
