Prefabricated Jump Pit Form With Inclined Sand Containment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jump pit forms are often inaccurately constructed onsite, leading to inefficiencies and increased costs, with sand from the pit frequently being thrown outside, requiring manual cleanup and lacking a mechanism for sand containment.
Innovation Solution
A prefabricated jump pit form comprising a base with inside and outside walls, support members, and a cap with an inclined surface to cover the sand area, including an optional sand catcher to contain sand, ensuring accuracy, durability, and economical construction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If jump pit forms are hand constructed onsite, then flexibility and adaptability are improved, but manufacturing precision and construction accuracy deteriorate
Solution Approach 1:
The jump pit form is divided into multiple modular sections that can be assembled onsite. Each section is pre-fabricated with precise dimensions, ensuring manufacturing precision while allowing flexible assembly configurations to adapt to different site requirements.
Solution Approach 2:
The form sections are pre-fabricated offsite with precise dimensions and configurations before being transported to the construction site. This preliminary action ensures high manufacturing precision is achieved while still allowing adaptability through selective assembly of pre-prepared components.
2Adaptability or versatility
If jump pit forms are hand constructed onsite, then on-site customization is improved, but productivity and construction time deteriorate
Solution Approach 1:
The form system is segmented into standardized modular sections that can be quickly assembled onsite. This segmentation enables rapid construction through simple assembly operations while maintaining the ability to customize the overall configuration by selecting and arranging different sections.
Solution Approach 2:
All form sections are pre-fabricated with precise dimensions and connection features before onsite assembly. This preliminary preparation significantly reduces onsite construction time while still allowing customization through the selection and arrangement of pre-made components.
3Device complexity
If traditional jump pit construction is used, then simplicity of structure is improved, but sand containment capability deteriorates
Solution Approach 1:
The form structure is merged with an integrated sand containment system. The containment walls are built as integral parts of the form structure itself, combining the supporting function with the sand retention function in a single unified system that prevents sand loss without requiring separate containment structures.
Solution Approach 2:
The form structure serves multiple functions simultaneously: it provides structural support for the jump pit, acts as a mold for concrete construction, and functions as a sand containment barrier. This multi-functionality prevents sand loss while maintaining relative structural simplicity.
4Manufacturing precision
If jump pit forms are prefabricated, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The prefabricated form is divided into standardized modular sections with simple, repeatable connection features. This segmentation maintains manufacturing precision through controlled factory production while reducing assembly complexity through consistent, easy-to-connect modules that can be assembled without complex alignment procedures.

AI summary
A form is provided for constructing a jump pit with a sand area. The form is constructed in sections. Each section has an inside wall and an outside wall. A support member is located between the outside wall and the inside wall. The sections are secured together onsite. Caps are mounted on the support members. The caps include an inclined surface which slops upwardly and away from the sand area forming the inclined surface. A cover over the sand area is supported by the inclined surface. Optionally, a chamber is located adjacent the outside wall. A grate covers the chamber and the grate is supported by a brace. A mat covers the grate. Openings in the grate and in the mat permit sand through them, thrown from the sand area to drop into the chamber.
