Solution Overview

Problem

Current training devices lack a versatile structure that can simulate an interactive sparring partner with high impact absorption while ensuring user safety, particularly in boxing and martial arts training, as they often result in injuries due to the heavy and dense nature of existing equipment.

Innovation Solution

An exercise assembly with an elongated support shaft and adjustable targets, including rotating targets with weighted and cushioned arms, and a resistance assembly that allows for continuous or restricted rotation, providing a dynamic training experience that mimics the unpredictability of a real sparring partner while protecting the user from injury.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a heavy and dense punching bag is used for training, then impact absorption capability is improved, but user safety deteriorates due to risk of wrist and ankle injuries

Engineering Contradiction:
Improveimpact absorption capabilityVSAvoiduser safety
Core Design Contradiction:
StrengthVSObject-affected harmful factors

Solution Approach 1:

The training device is divided into multiple separate targets (punching balls, kicking balls, boxing gloves) that are distributed along a vertical shaft, rather than using a single heavy bag. Each target is lightweight and can be independently struck, providing impact absorption while eliminating the injury risks associated with heavy dense bags.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The density and weight parameters of the training targets are fundamentally changed from heavy and dense (traditional punching bags) to lightweight and less dense (punching balls, kicking balls, boxing gloves). This parameter change maintains impact absorption capability while dramatically improving user safety by eliminating the harmful effects of excessive weight and density.

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If a stationary training product is used, then structural simplicity is improved, but training versatility deteriorates as it cannot simulate interactive sparring

Engineering Contradiction:
Improvestructural simplicityVSAvoidtraining versatility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The training device transitions from a completely stationary structure to a dynamic system where targets can rotate along the vertical shaft when struck. This rotational movement simulates the unpredictable motion of a real sparring partner while maintaining relatively simple structural components (shaft, bearings, resilient means).

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device incorporates multiple types of targets (punching balls for hand strikes, kicking balls for leg strikes, boxing gloves for various strikes) that can be positioned at different heights on the shaft. This multi-functionality allows the same basic structure to support diverse training activities, greatly enhancing training versatility without proportionally increasing structural complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If a target is made to rotate on contact to simulate sparring partner, then training versatility is improved, but device complexity increases

Engineering Contradiction:
Improvetraining versatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple functional elements into integrated components: the resilient means (springs or elastomeric materials) are built into the targets themselves rather than being separate mechanisms; the rotational capability is achieved through simple bearing assemblies integrated with the shaft; the weighting system is incorporated directly into the target structure. This merging reduces overall device complexity while maintaining training versatility.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The targets are equipped with internal resilient means (springs or elastomeric materials) that automatically provide the restoring force needed for rotation and return to position. This self-service mechanism eliminates the need for complex external actuation systems, motors, or control mechanisms, achieving rotational functionality with minimal added complexity.

Inventive Principle:
Principle #25Self-service

4Adaptability or versatility

If multiple targets are adjustably mounted on a shaft, then training versatility is improved, but device complexity increases

Engineering Contradiction:
Improvetraining versatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent provides for adjustable mounting of targets at different heights on the shaft, allowing customization for different users and training scenarios. However, the adjustment mechanism is relatively simple (likely involving basic clamps or positioning slots), providing sufficient versatility without implementing overly complex adjustable systems. This partial action approach achieves adequate adaptability while controlling device complexity.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

An improved exercise assembly structured to be struck by a user includes a base supporting a shaft on a supporting surface. A support shaft extends outwardly from the supporting surface. At least one rotating targets is connected to the support shaft and extends outwardly. A resistance assembly is adjustably mounted on the shaft into and out of a position relative to a path of travel of at least one rotating target. The position includes the resistance assembly in engagement with at least one rotating target. The rotating target includes an elongated arm including a predetermined weighted construction and a safety portion thereon.
