Solution Overview

Problem

Existing playground swing equipment, despite attempts to enhance safety through rubber dampers and elastomeric materials, still poses risks due to limited shock absorption and rigidity, particularly in kinetic situations, leading to potential injuries from impact.

Innovation Solution

A basket swing with a double/single walled impact surface produced via volume moulding methods, such as rotation or inflation moulding, providing a larger impact area, increased elasticity, and a rigid wall thickness, combined with a negative slope for better grip, and multiple shock-absorbing sections for enhanced safety and durability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If rubber dampers and elastomeric materials are used in swing equipment, then safety is improved, but shock absorption capability remains limited due to rigidity requirements

Engineering Contradiction:
ImprovesafetyVSAvoidimpact severity
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The swing seat is divided into multiple independent shock-absorbing sections (front, rear, and side sections) rather than using a single rigid structure. Each section contains shock-absorbing elements that can independently deform to absorb impact energy, allowing the seat to maintain overall structural integrity while providing localized flexibility for safety.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the physical parameters of the shock-absorbing elements by using materials with specific elasticity moduli and designing elements with varying cross-sectional areas and wall thicknesses. This allows optimization of the balance between rigidity (for structural strength) and flexibility (for shock absorption), resolving the contradiction between safety and impact severity.

Inventive Principle:
Principle #35Parameter changes

2Strength

If a rigid structure is used for the swing seat, then durability is improved, but flexibility and shock absorption are reduced

Engineering Contradiction:
ImprovedurabilityVSAvoidflexibility
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The swing seat structure is segmented into rigid connecting portions and flexible shock-absorbing sections. The rigid portions provide structural strength and durability, while the segmented shock-absorbing sections with elastic elements provide the necessary flexibility and shock absorption capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs composite construction combining rigid materials (such as metal or rigid plastic for connecting portions) with elastic materials (such as rubber or elastomers for shock-absorbing elements). This composite approach allows the structure to simultaneously achieve durability from rigid components and flexibility from elastic components.

Inventive Principle:
Principle #40Composite materials
