Lightweight Foam Proximity Training Device for Safe Partner Practice
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current training devices are inadequate for at-home use, particularly for partner-oriented movement activities, as they are often heavy, awkward, and not suitable for solo practice, leading to potential injuries due to improper technique and lack of balanced biomechanical responses.
Innovation Solution
A lightweight, minimally resistant training device resembling a human spine with attached arms and legs, made of polyethylene foam and variable-density polyurethane foam, designed for slow and controlled movements to simulate a partner's presence, allowing users to practice fundamental biomechanical responses without an instructor or partner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional training dummies are used for martial arts training, then training effectiveness for competitive purposes is improved, but the device becomes heavy and awkward to maneuver, causing difficulty in operation
Solution Approach 1:
The training device is divided into multiple detachable segments including a head portion, torso portion, and limb portions that can be assembled and disassembled. This segmentation reduces the weight and complexity of each individual component, making the device easier to maneuver while maintaining overall training effectiveness when assembled.
Solution Approach 2:
The training device incorporates dynamic characteristics by allowing the limb portions to be positioned in various configurations and secured at different angles. This dynamic adjustability enables the device to adapt to different training scenarios while remaining lightweight and easy to reposition.
2Reliability
If training dummies are filled with heavy material for realistic training, then training realism is improved, but the device becomes heavy and awkward, leading to improper use and potential injury
Solution Approach 1:
The training device uses lightweight foam materials instead of heavy filling materials, fundamentally changing the weight parameter while maintaining the structural form and training applicability. This parameter change reduces the risk of injury from improper handling while preserving the essential training functions.
Solution Approach 2:
The device employs inexpensive foam materials that can be easily replaced if damaged, rather than using expensive, heavy materials that pose safety risks. This approach prioritizes user safety while maintaining training effectiveness.
3Manufacturing precision
If training dummies are made with complex internal structures for balanced posture, then training accuracy is improved, but manufacturing complexity increases and proper balancing is difficult to achieve
Solution Approach 1:
The training device achieves proper balancing through local adjustments in the foam density and distribution within specific regions of the torso and limb portions, rather than requiring complex internal structures throughout. This localized approach to quality control simplifies manufacturing while ensuring correct posture representation.
4Reliability
If training devices are specialized for specific activities, then activity-specific training effectiveness is improved, but versatility across different activities and age groups is reduced
Solution Approach 1:
The training device is designed with universal applicability through its modular segment structure and adjustable limb configurations, allowing it to be used for multiple martial arts disciplines, dance training, and rehabilitation activities across different age groups, rather than being specialized for a single activity.
Solution Approach 2:
The device incorporates dynamic adjustability in limb positioning and configuration, enabling it to adapt to different training requirements and activities. This dynamic capability allows the same base device to serve multiple functions across different martial arts styles and skill levels.

AI summary
A proximity training device for use in training of activities (FIG. 3), that anybody can use whether they are a beginner, intermediate, or advanced activity enthusiast (user) participating in martial arts or another partner-oriented activities. The user is able to utilize the training device safely allowing them to maintain their physical fitness activities. The user engages the training device maintaining an upright posture and initiates movement thereby activating the training device. It is held within the same proximity of an in-person training partner, allowing the user to practice the fundamental biomechanical responses and other skills required for their preferred chosen activities. The training device is lightweight and easy to store. The arms are easily removed and are adjustable for optimizing user comfort and training device functionality. The training device is easy to assemble and disassemble which allows for easy transport and storage of the training device.
