Artificial Limb With Internal Cord For Dynamic Flailing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combat training devices fail to effectively simulate the flailing motion of an actual assailant, limiting the realism and effectiveness of martial arts and self-defense training.
Innovation Solution
An artificial limb system comprising a mechanically coupled upper arm, lower arm, and cord with end ball, attached to straps, which flail upon impact, mimicking the movement of an assailant by using a cord that travels through a hollow portion of the upper arm and is secured with straps to equipment, allowing for dynamic movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid members are used to form the artificial limb structure, then structural stability is improved, but the ability to flail and simulate realistic movement deteriorates
Solution Approach 1:
The artificial limb is divided into multiple segments (upper arm, lower arm, hand) connected by joints, allowing each segment to move independently and flail realistically while maintaining overall structural stability through the segmented architecture
Solution Approach 2:
The patent transitions from static rigid members to dynamic components with joints and cords that enable movement. The cords allow the limb segments to flail dynamically in response to strikes, simulating realistic assailant movement while the joint structures maintain necessary stability
2Loss of information
If parallel members are attached to a column to resemble a body, then target recognition is improved, but realistic flailing motion deteriorates
Solution Approach 1:
The parallel members are replaced with articulated limb segments connected by joints and cords, transforming the static target structure into a dynamic system that flails realistically when struck, while still maintaining the human-like configuration for target recognition
Solution Approach 2:
The artificial limb copies the structure and movement patterns of actual human limbs, including the arrangement of upper arm, lower arm, and hand segments, enabling both realistic flailing motion and recognition as a human target
3Strength
If the cord travels through a hollow portion of the upper arm, then structural integrity is improved, but device complexity increases
Solution Approach 1:
The cord is nested within the hollow portion of the upper arm structure, allowing the cord to be contained within the limb itself rather than attached externally. This integrates the cord into the structural design, maintaining structural integrity while the added internal routing does increase device complexity

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances the realism of combat training by allowing users to practice against a target that flails like an actual assailant, improving the effectiveness of martial arts and self-defense training through more realistic and dynamic resistance.
Implementation Method 1
When a user strikes the piece of equipment the first upper arm, first lower arm and first end ball flail in a manner that simulates an actual assailant

AI summary
An artificial limb assists a user in combat training. The artificial limb comprises a first arm retainer mechanically coupled to a first upper arm and a first cord, where the first cord travels through a first hollow portion of the first upper arm. The first cord is immediately adjacent to a first lower arm and terminates at first end ball. The first arm retainer is mechanically coupled to a piece of equipment by an upper strap and a lower strap. When a user strikes the piece of equipment the first upper arm, first lower arm and first end ball flail in a manner that simulates an actual assailant.
