Solution Overview

Problem

Children often attempt to climb up slides to access elevated play structures, leading to congestion and potential safety hazards, and existing climbing units are not distinct enough from slides to prevent this behavior.

Innovation Solution

Incorporation of net-containing and suspended portions, along with novel mounting assemblies that reduce obstructions, to create a continuous climbing pathway that is easily distinguishable from slides, using components like tubular elements, flexible couplers, and overhead trusses to support the climbing units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If children climb up slides to access elevated play structures, then they can reach the elevated structures, but congestion and safety hazards occur

Engineering Contradiction:
Improveaccess to elevated structuresVSAvoidcongestion and safety hazards
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The climbing unit is divided into distinct segments: a net-containing portion for initial climbing, a rigid tubular portion for structured climbing, and a suspended portion for continued ascent. This segmentation creates a dedicated climbing pathway that separates climbing traffic from slide traffic, eliminating congestion and safety hazards while maintaining easy access to elevated structures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The net-containing portion acts as an intermediary element between the ground and the rigid tubular portion, providing a gentle transition and initial climbing surface. This intermediary structure guides children into the proper climbing pathway without forcing them to climb slides, thereby preventing congestion and safety issues while maintaining accessibility.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If climbing units are mounted close to the ground, then installation is simpler, but the play space is obstructed

Engineering Contradiction:
Improveinstallation simplicityVSAvoidplay space
Core Design Contradiction:
Ease of manufactureVSArea of stationary object

Solution Approach 1:

The climbing unit transitions from ground-mounted to suspended mounting by utilizing overhead trusses and coupling units that attach to elevated playground structures. This dimensional change moves the climbing unit from the ground plane to an elevated position, freeing up ground-level play space while maintaining installation feasibility through standardized coupling mechanisms.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The coupling units and overhead trusses serve multiple functions: they support the climbing unit, enable elevated mounting to clear play space, and provide structural stability. This multi-functionality allows the same mounting system to achieve both space clearance and installation reliability without requiring complex ground-level foundations.

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

3Stability of the object's composition

If rigid structures are used for climbing units, then structural stability is improved, but aesthetic integration with playground structures is reduced

Engineering Contradiction:
Improvestructural stabilityVSAvoidaesthetic integration
Core Design Contradiction:
Stability of the object's compositionVSShape

Solution Approach 1:

Different portions of the climbing unit have different structural qualities: the net-containing portion is flexible and adaptable for aesthetic integration, while the rigid tubular portion provides structural stability where needed. This local differentiation allows the climbing unit to achieve both aesthetic harmony with playground structures and the necessary structural stability for safe climbing.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The climbing unit combines different materials and structural characteristics: flexible netting for aesthetic integration and gentle climbing, rigid tubular elements for structural stability, and flexible couplers for movement accommodation. This composite approach allows the structure to simultaneously achieve aesthetic integration with playground environments and the structural stability required for safe operation.

Inventive Principle:
Principle #40Composite materials

AI summary

Climbing units that provide an enhanced play experience through the incorporation of any of a variety of elements including nets, suspended portions, and coupling elements, and to playground structures that contain those climbing units. In some embodiments, the climber unit may comprise one or more rigid portions and one or more net-containing portions connected end-to-end to produce a continuous climbing pathway. In other embodiments, the climber unit may comprise one or more rigid portions and one or more suspended portions connected end-to-end to produce a continuous climbing pathway. The suspended portion may be attached to adjacent rigid portions by flexible couplers, such that the suspended portion will move when a child climbs through it. In other embodiments, the climber unit may be mounted to an elevated playground structure such that there are no footers connecting the climber unit to the ground.
