Monkey Bar Frame Layout for Stable Small-Area Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing playground equipment with monkey bars faces stability issues on soft ground surfaces, as traditional anchoring methods are impractical and may interfere with underground infrastructure, and extension legs or braces are not suitable for small areas, causing obstruction and increased footprint.
Innovation Solution
A playground apparatus with a frame that tapers inwardly towards its ends, supported by upright poles with feet to increase ground engagement, and adjustable clamp assemblies for monkey bars, allowing for stable installation without external support devices, suitable for small areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If extension legs or braces are used to provide additional stability, then the frame's stability is improved, but the frame's surface area footprint is substantially increased
Solution Approach 1:
The support poles transition from a vertical orientation at the inner ends to an outwardly extending orientation at the lower ends, utilizing spatial dimensionality to achieve stability without increasing the horizontal footprint of the frame structure
2Stability of the object's composition
If extension legs or braces are used to provide additional stability, then the frame's stability is improved, but obstruction to gardening tasks such as lawn mowing is increased
Solution Approach 1:
The support poles extend outwardly in a downward orientation, utilizing the vertical and diagonal dimensions to provide stability while keeping the horizontal space clear for gardening operations
3Area of stationary object
If the outermost sides of the frame taper inwardly towards the first ends, then the surface area footprint is reduced, but the structural complexity is increased
Solution Approach 1:
The frame employs asymmetric tapering of the outermost sides toward the first ends, creating an irregular geometric form that reduces footprint while the support poles provide structural compensation for the non-uniform shape

AI summary
A playground apparatus comprises a frame adapted to rest on a ground surface, the frame comprising a pair of laterally opposed outermost sides having first ends arranged towards an outermost end of the frame and second ends opposed to the first ends, wherein the outermost sides taper inwardly towards the first ends. Monkey bars are supported by the frame above the ground surface that comprise a plurality of graspable rungs arranged in a row. The playground apparatus also comprises a pair of upright support poles, wherein uppermost sections of the upright support poles are connected to the frame towards the first ends such that the uppermost sections are laterally inwardly disposed relative to the second ends. Lowermost ends of the upright support poles extend outwardly away from one another and towards the outermost end to increase a surface area of the ground surface engaged by the upright support poles.
