Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for constructing throwing circles for sports like hammer, shot put, and discus are inaccurate, labor-intensive, and costly, as they are built in parts rather than as prefabricated units.
Innovation Solution
A prefabricated form consisting of half sections with semi-circles and securing means to form a full circle, which can be easily assembled and installed, ensuring accuracy and economy, and is designed for both hammer and discus throwing circles with variations for size and features like toe boards and drainage tubes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If throwing circles are constructed in parts, then ease of transport is improved, but manufacturing precision and accuracy deteriorate
Solution Approach 1:
The form is divided into two half-sections that can be separately manufactured and transported, then assembled on-site to form the complete circle. This segmentation allows the form to be transported more easily while maintaining manufacturing precision through standardized half-section designs that ensure accurate reassembly.
Solution Approach 2:
The half-sections are pre-manufactured under controlled conditions before being transported to the construction site. This preliminary manufacturing allows for precise dimensional control and quality assurance, while the modular design enables easy transport and subsequent assembly.
2Ease of operation
If forms are constructed in parts, then ease of transport is improved, but labor intensity and construction time increase
Solution Approach 1:
The form is segmented into standardized half-sections that can be pre-fabricated and transported separately. This segmentation reduces on-site construction time while maintaining ease of transport, as each half-section can be independently handled and assembled quickly.
Solution Approach 2:
The two half-sections are designed to combine seamlessly to form the complete circle. This merging approach allows for rapid on-site assembly, reducing the overall construction time while maintaining the benefits of modular transport.
3Ease of operation
If forms are constructed in parts, then ease of transport is improved, but construction cost increases
Solution Approach 1:
The form is divided into standardized half-sections that can be manufactured efficiently under controlled conditions. This segmentation enables better material utilization and reduced waste, lowering construction costs while maintaining ease of transport for the modular components.
Solution Approach 2:
The design parameters of the half-sections are standardized to optimize manufacturing efficiency and material usage. This standardization reduces construction costs through better inventory management and reduced waste, while the modular design maintains ease of transport.
4Manufacturing precision
If prefabricated forms are used, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The form is segmented into two identical half-sections, which simplifies the overall design while maintaining high manufacturing precision. The symmetry of the segmentation reduces design complexity compared to more complex modular systems, while still enabling precise assembly.

AI summary
A form for constructing a thrower's circle includes a pair of half sections. Each half section has an upper surface and a base surface and two full length members and two half length members. The full length members and the half length members are connected together substantially at right angles to form a rectangle with four corners. A corner brace is located in each of the four corners. An inside cross member and an outside cross member extend between the half length members and are generally parallel to the full length members. A pair of semi-circles, each having substantially the same diameter that is larger than the length of the half length members and less than the length of the full length members. Means are provided for securing the half sections together so that the semi-circles form a full circle. Tubes extend from the circle toward the base to drain water from with in the circle.
