Wheel-Guided Non-Hanged Swing Structure for Safer Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional non-hanged swings face safety issues due to the rectangular shape of top and floor constructions causing cutting effects, lack of effective covers for the mechanism leading to user contact with wheels, instability during strong swinging, and water accumulation damaging the cloth canopy.
Innovation Solution
The solution involves changing the floor construction to a special H-shape to eliminate cutting effects, using a specially shaped and angled top cover made of flexible material with oval holes, incorporating wheel limitation discs to maintain stability, and attaching an arched element to the roof construction to prevent water accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a rectangular shape of top construction and floor construction is used, then the structure is simple and easy to manufacture, but it generates dangerous cutting effects between parts
Solution Approach 1:
The patent applies curvature by replacing the rectangular shape with an oval shape for both the top construction and floor construction. This curved geometry eliminates the sharp corners that cause cutting effects, while the oval profile maintains structural integrity and ease of manufacture through standard curved profile extrusion processes.
2Stability of the object's composition
If a stopper is used to prevent strong swinging, then the mechanism stability is improved, but the top construction can fall down from the mechanism during strong swinging or movement
Solution Approach 1:
The oval-shaped floor construction provides a curved guide path for the wheels, allowing controlled movement while maintaining stability. The curved geometry naturally guides the top construction along a smooth arc, preventing sudden drops or disengagement that could occur with rigid stoppers, while still limiting excessive swinging through the constrained oval path.

AI summary
A non-hanged swing on a wheel mechanism with safety components comprising stabile floor construction (1) and footrest panel (10), movable top construction (2) with two opposite benches (11) and (12), table (13), armrests (14) and roof construction (4), (5), (6) and (7) with cloth roof (30). The top construction with benches, table, armrests and roof slides all together as one piece horizontally from side to side on a wheel mechanism (41) and (42) which is further equipped by limitation disc (22). The wheel mechanism is protected by side cover (20) and top cover (21).
