Solution Overview

Problem

Existing fitness devices with fixed hanging positions are limited in adaptability, making them unusable in scenarios where the preset positions do not meet the required hanging lengths.

Innovation Solution

An entertainment and leisure device with adjustable hanging positions, featuring a bundling belt, a ribbon with marked fixed points, self-locking sliding buckles, and a lock buckle, allowing users to adjust the hanging length and position to suit various needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a single-piece fitness device is fixed with nylon slings by stitching, then the device structure is simple and easy to manufacture, but the hanging position is fixed and cannot be adjusted to meet different usage requirements

Engineering Contradiction:
Improvedevice structure simplicityVSAvoidhanging position adjustability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The device is divided into multiple segments: the main body, multiple separate nylon slings of different lengths, and connection points. This segmentation allows each sling to be independently adjusted and selected based on hanging position requirements, resolving the contradiction between simple structure and position adjustability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The device transitions from a fixed hanging position to a dynamic, adjustable configuration. Multiple slings with different lengths can be connected to different connection points on the main body, enabling the hanging position and length to be dynamically adjusted according to various usage scenarios while maintaining a simple overall structure.

Inventive Principle:
Principle #15Dynamics

2Device complexity

If two preset hanging positions are used, then the device structure is simple, but the device cannot be used when the preset positions do not meet the required hanging lengths

Engineering Contradiction:
Improvehanging position configurationVSAvoidscenario adaptability
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The device incorporates multiple slings of different lengths that can be used in various combinations and configurations. This multi-functionality allows the same device to adapt to different hanging length requirements and usage scenarios, enhancing versatility without significantly increasing structural complexity.

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

Solution Approach 2:

The device provides multiple slings with different length parameters. By changing which sling is used or how slings are combined, the effective hanging length parameter can be adjusted to match different scenario requirements, resolving the limitation of fixed preset positions.

Inventive Principle:
Principle #35Parameter changes
