Extendable Jumping Platform With Curved Lapping Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional extendable jumping platform assemblies are unsafe due to serrated joint seams during lateral extension, and they incur high costs and material volumes when attempting to increase leaping height or sliding length.
Innovation Solution
The design incorporates a sliding portion with a guiding end and a jumping end, lateral mounting and lapping portions with matching curvature, and a docking portion, along with extending boards featuring similar features, allowing safe lateral extension and adjustable sliding length without increasing material volume or costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If conventional extendable jumping platform assemblies use lateral extension with mounting grooves and tenons, then the lateral leaping range is extended, but serrated joint seams are formed causing safety hazards
Solution Approach 1:
The patent applies curvature by designing the lateral mounting portion and lateral lapping portion with matching curved surfaces that follow the arc of the sliding portion. This curved design allows the extending board to align seamlessly with the jumping platform, eliminating serrated joint seams and ensuring smooth lateral extension without safety hazards.
2Length of moving object
If conventional extendable jumping platform assemblies increase base portion volume to extend sliding length, then the sliding length is extended, but material volume and packaging costs increase
Solution Approach 1:
The patent segments the extending board into functional portions: a base portion for mounting, a sliding portion for the extended sliding surface, and lateral mounting/lapping portions for connection. This segmentation allows the extending board to achieve extended sliding length without requiring a proportionally larger base portion, thereby reducing material volume and packaging costs.
Solution Approach 2:
The patent extends the sliding length by adding the extending board in the longitudinal direction rather than increasing the base portion volume in three dimensions. This dimensional approach allows length extension while maintaining compact material usage and reducing packaging requirements.
3Adaptability or versatility
If conventional extendable jumping platform assemblies use regular and uniform shape, then the structure is simple, but the lateral leaping range and sliding length cannot be extended according to different usage demands
Solution Approach 1:
The patent applies dynamics by designing an extendable structure where the extending board can be mounted at different positions along the sliding portion. The lateral mounting portion with multiple mounting grooves and the lateral lapping portion with multiple mounting tenons allow flexible positioning, enabling adjustment of leaping height and sliding length according to different usage demands without overly complicating the structure.

AI summary
The jumping platform has a lateral mounting portion and a lateral lapping portion respectively formed on two lateral surfaces of the jumping platform. The extendable jumping platform assembly has multiple jumping platforms, multiple extending boards, and a jumping board. The jumping platform assembly has a lateral mounting portion and a lateral lapping portion so that the jumping platforms and the extending boards can be juxtaposed for extending lateral leaping range safely and extending sliding length according to the usage. One end of the extending board is mounted on the jumping platform, the other end of the extending board is mounted on the jumping board, and each one of the extending board and the jumping board has a leg assembly for supporting.
