Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing sport training equipment with ropes, such as tether ball, has the rope and ball fixedly connected, preventing the ball from being used independently.

Innovation Solution

An easy-to-disassemble connector with a first and second connecting assembly, each equipped with a rotating-embedded unit, allowing for separation and independent use of the ball.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the rope and ball are fixedly connected, then the connection strength is improved, but the adaptability deteriorates

Engineering Contradiction:

Improveconnection strengthVSAvoidadaptability

Core Design Contradiction:

StrengthVSAdaptability or versatility

Solution Approach 1:

The connector is divided into two separable assemblies: a first connecting assembly with a first rotating-embedded unit for connecting to the rope, and a second connecting assembly with a second rotating-embedded unit for connecting to the ball. This segmentation allows the connector to be assembled when rope-based training is needed and disassembled when the ball should be used independently, thus maintaining both connection strength during use and adaptability for different training modes.

Inventive Principle:

Principle #1Segmentation

2Reliability

If the rope and ball are fixedly connected, then the reliability is improved, but the ease of operation deteriorates

Engineering Contradiction:

ImprovereliabilityVSAvoidease of operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The connector transitions from a static fixed connection to a dynamic separable connection. The rotating-embedded units enable the connector to be easily assembled and disassembled through rotational motion, making the connection state changeable based on training needs. This dynamic design maintains reliability when connected while significantly improving ease of operation for assembly and disassembly.

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If the connector is made detachable, then the adaptability is improved, but the device complexity increases

Engineering Contradiction:

ImproveadaptabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rotating-embedded units are designed with a nested structure where the embedded pin fits into the embedded slot. This nesting design allows the two connecting assemblies to be compact when connected and easily separated when disconnected, achieving adaptability without excessive complexity. The nested structure provides a straightforward assembly and disassembly mechanism.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

An easy-to-disassemble connector and sport training equipment has a first connecting assembly and a second connecting assembly that can be separated from or connected to each other. The first connecting assembly is connected to a rope, and the second connecting assembly is connected to a ball. The first connecting assembly has a first rotating-embedded unit, and the second connecting assembly has a second rotating-embedded unit connected to the first rotating-embedded unit. When the first rotating-embedded unit and the second rotating-embedded unit are connected to each other, it is convenient for the user to hold the rope to assist in sport trainings. When the first rotating-embedded unit and the second rotating-embedded unit are separated from each other, the first connecting assembly and the second connecting assembly are separated from each other and the ball can be used independently.
