Modular Form Assembly for Consistent Jump Pit Dimensions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The construction of long jump/triple jump pits often results in uneven dimensions due to difficulties in positioning and securing form components during the pouring and curing of moldable forming composition, leading to variations in size and the need for custom covers.
Innovation Solution
A form assembly comprising a frame member with a removable form member and connectors to securely attach and detach components, ensuring a level ledge for a standard cover, allowing for efficient construction and removal of the form components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If custom-built form components are used for each jump pit, then the jump pit can be made to specific dimensions, but the dimensions vary due to shifting of form assembly components during pouring and curing
Solution Approach 1:
The form assembly is divided into modular components (form members, frame members, connectors) that can be assembled in a standardized configuration. Each component is designed with specific connection interfaces that ensure consistent positioning when assembled together, reducing dimensional variations between different jump pits.
Solution Approach 2:
The form assembly components are pre-designed and pre-configured with standardized dimensions and connection mechanisms before construction. The connectors are designed to secure form members in predetermined positions, ensuring consistent ledge levels and overall dimensions before the pouring process begins.
2Shape
If L-shaped channels are used to form the ledge, then the cover can be received, but the moldable forming composition urges the channel upwards and laterally away from the form
Solution Approach 1:
Connectors are introduced as intermediary elements between the form members and the ledge-forming components. These connectors provide secure mechanical attachment points that resist the upward and lateral forces exerted by the moldable forming composition, keeping the ledge-forming components in their intended positions.
Solution Approach 2:
The form assembly uses composite construction combining rigid form members (wood or metal) with standardized connectors. This composite structure provides both the shaping capability for the ledge and the structural strength to resist forces during pouring, addressing both the shape requirement and the stability issue.
3Manufacturing precision
If form components are securely attached to create precise dimensions, then dimensional consistency is achieved, but the form components are difficult to remove after curing
Solution Approach 1:
The connection between form members and the contained structure transitions from a secured state during pouring to a removable state after curing. The connectors are designed to provide strong attachment during the forming process but allow for controlled removal afterward, enabling the form assembly to be reused for subsequent jump pit constructions.
Solution Approach 2:
The form assembly components are designed to be temporary structures that are removed after serving their purpose. The standardized connectors and modular design enable efficient disassembly and recovery of form members for reuse in constructing additional jump pits, reducing waste and construction costs.
