Wall-Cap Net Securing With Rod-Cable Impact Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing net securing systems for sports fields have weak points that break easily when impacted by balls or objects, leading to potential failure.
Innovation Solution
A net securing apparatus with a wall cap having a rod and cable system, where the rod is intertwined with the net and secured by a cable wrapped around it, distributing impact loads and preventing the net from dislodging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the net is secured by pinching it between wall portions, then the net can be attached to the wall, but weak points are created that break easily when impacted by balls or objects
Solution Approach 1:
The wall cap is divided into an upper cavity for net insertion and a lower cavity for wall insertion, allowing the net to be secured in a dedicated upper section while the lower section provides structural anchoring. This segmentation separates the net-securing function from the wall-anchoring function, distributing stress more effectively.
Solution Approach 2:
The rod is inserted through the net and positioned within the upper cavity, then the entire assembly (wall cap containing rod and net) is inserted into the wall. This nested arrangement allows the net to be protected and secured within the wall cap structure, which itself is secured within the wall.
2Reliability
If a rod is inserted through the net and secured with a cable wrapped around it, then impact forces are distributed along the rod, but the device complexity increases
Solution Approach 1:
The rod, cable, and wall cap are combined into an integrated securing system where the rod provides structural support, the cable provides tensile restraint, and the wall cap provides the mounting interface. This merging of components creates a unified system that distributes and manages impact forces effectively.
Solution Approach 2:
The rod acts as a cushioning element that absorbs and distributes impact forces before they reach the net. By positioning the rod behind the net and securing it with a cable, the system prepares for potential impacts in advance, allowing forces to be distributed along the rod's length rather than concentrated at single attachment points.

AI summary
Apparatus, systems, and methods for securing a net. The system includes a wall cap having an upper cavity and a lower cavity and a gap that provides access to the upper cavity. A wall is positioned within the lower cavity. A portion of a net is positioned within the upper cavity of the wall cap. A rod positioned within the upper cavity of the wall cap is intertwined through the portion of the net positioned within the upper cavity of the wall cap. The rod may have an outer diameter that prevents the rod from moving through the gap in the wall cap. A cable is wrapped around the rod along the length of the wall cap. Portions of the cable are positioned above the rod along its length and portions of the cable are positioned through the wall and the wall cab below the rod.
