Solution Overview

Problem

Existing swings made from discarded tires are prone to chalking and unsuitable for direct contact with children, and traditional spinning saucer swings may not provide the desired motion variety and safety features.

Innovation Solution

A spinner swing design featuring a suspension frame with a horizontal beam, adjustable suspension connectors, and a fabric-covered outer seat frame with multiple seats and seatbacks, allowing for various motion configurations including swinging, rotating, and tilting, while ensuring user safety with fabric panels and seat frame rails.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If discarded tires are used to make swings, then the swing structure is simple and durable, but the material causes chalking and is unsuitable for direct contact with children

Engineering Contradiction:

ImprovedurabilityVSAvoidmaterial unsuitability for child contact

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

A fabric panel is mounted across the inner seat frame to form a flexible seating surface that replaces direct contact with rigid tire material. The fabric panel provides a soft, child-safe surface while the underlying tire structure maintains its structural integrity and durability.

Inventive Principle:

Principle #30Flexible shells and thin films

2Adaptability or versatility

If traditional spinning saucer swings are used, then children can spin, but the motion variety is limited and safety features are insufficient

Engineering Contradiction:

Improvemotion varietyVSAvoidsafety

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The swing frame is designed with suspension line systems that allow dynamic motion in multiple directions. The swing can rotate around the horizontal beam, tilt forward and backward, and swing side-to-side, providing varied motion patterns that adapt to different user preferences and age groups.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Seatbacks are positioned to prevent excessive backward rotation, and the suspension system is designed to limit extreme tilting motions. These preliminary safety measures prevent harmful motions before they can occur, ensuring child safety while maintaining motion versatility.

Inventive Principle:

Principle #9Preliminary anti-action

3Object-affected harmful factors

If a fabric panel is mounted across the inner seat frame, then child safety is improved, but the device complexity increases

Engineering Contradiction:

Improvechild safetyVSAvoidstructure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The fabric panel is integrated with the existing inner seat frame structure, combining the safety function with the structural framework. The fabric panel serves dual purposes: it provides a soft seating surface for child safety and simultaneously acts as a structural element that distributes loads across the frame.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A spinner swing includes a suspension frame, including a pair of front supports and a pair of rear supports. The pair of front supports and the pair of rear supports holds a horizontal beam. The pair of front supports includes a first front support and a second front support. The pair of rear supports includes a first rear support and a second rear support. A suspension line system is connected to the horizontal beam. A swing frame is suspended from the suspension line system. The suspension line system allows rotation of the swing frame. The swing frame has an outer seat frame that is a rounded circular or oval shape. A fabric panel is mounted across the outer seat frame. A first seat is mounted in the swing frame.
