Fencing Training Device Retractable Connector Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beginning fencers face challenges in learning proper lunge technique in fencing due to the lack of feedback from existing training devices, which often fail to identify and correct improper technique.
Innovation Solution
A fencing training device with a retractable connector system that provides feedback through audible and tactile cues by coupling a first part to the fencing weapon and a second part to the fencer's leg, allowing the connector to extend and retract based on proper or improper technique, helping to correct sync issues between the arm and leg movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional fencing training devices are used, then fencers can practice basic movements, but no feedback is provided regarding improper technique
Solution Approach 1:
The patent implements feedback by using a retractable connector that provides tactile resistance and audible feedback when the fencer performs incorrect movements. The connector extends and retracts based on proper vs. improper technique, giving immediate sensory feedback to the user about their form without requiring complex electronic sensors or processors.
Solution Approach 2:
The retractable connector acts as an intermediary mechanical element between the fencer's body and the training device. It mediates the interaction by physically responding to movement patterns, translating complex technique assessment into simple tactile and auditory feedback that the fencer can immediately perceive and correct.
2Reliability
If fencers practice without feedback mechanisms, then training can be simple and device complexity remains low, but improper technique cannot be identified or corrected
Solution Approach 1:
The retractable connector provides reliable technique correction through mechanical feedback. When the fencer performs a lunge with proper form, the connector remains relatively stable; when improper form is used, the connector extends or retracts, providing reliable indication of technique errors without requiring complex sensing systems.
Solution Approach 2:
The device enables self-service technique correction by providing immediate tactile and auditory feedback that allows the fencer to self-diagnose and self-correct improper movements. The fencer learns through direct interaction with the device's mechanical response rather than requiring external coaching intervention for every error.
3Loss of information
If the retractable connector provides continuous resistance, then proper technique feedback is maintained, but the device requires more force and energy to operate
Solution Approach 1:
The retractable connector operates through periodic extension and retraction cycles rather than continuous resistance. It engages and disengages based on the fencer's movement phase, providing feedback only when technique assessment is needed, thereby reducing overall energy expenditure while maintaining effective feedback during critical movement phases.
Solution Approach 2:
The connector's resistance parameter changes dynamically based on movement detection. Rather than maintaining constant resistance, the system adjusts the level and presence of resistance according to whether proper or improper technique is detected, optimizing the balance between feedback provision and energy requirements.
