Collapsible Climbing Net with Telescoping Poles for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable telescoping, folding, and extending ladders are cumbersome to store due to their width, which compromises safety and comfort for users, especially children, and are not easily stowable in confined spaces.
Innovation Solution
A collapsible portable climbing net with a flexible netting material and a rigid frame that can be folded, collapsed, telescoped, and separated, allowing it to be compactly stored and easily assembled for use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ladder width is increased to improve safety and comfort for climbing, then the climbing safety and comfort are improved, but the storage space requirement increases
Solution Approach 1:
The ladder is divided into multiple telescoping sections that can be collapsed into one another, allowing the wide climbing surface to be reduced to a compact storage size. Each section contains rungs and side rails that can be nested, maintaining the wide climbing width when deployed but reducing storage volume when collapsed.
Solution Approach 2:
The ladder employs telescoping mechanisms that allow dynamic transformation between an extended wide configuration for safe climbing and a collapsed narrow configuration for compact storage. The side rails and rungs can move relative to each other, enabling the structure to adapt its width based on whether it is being used or stored.
2Volume of stationary object
If the ladder is designed to be collapsible for compact storage, then the portability is improved, but the structural complexity increases
Solution Approach 1:
The ladder sections are designed to nest within each other like dolls, with smaller sections fitting inside larger sections. This nesting arrangement allows the complex telescoping mechanism to be compacted efficiently, reducing storage volume while managing the structural complexity through a systematic nested configuration.
Solution Approach 2:
The collapsible mechanism transforms the ladder from a two-dimensional wide surface when collapsed to a three-dimensional extended structure when deployed. By utilizing vertical telescoping motion, the ladder achieves compact storage in a reduced volume while maintaining its wide climbing surface when in use.
3Adaptability or versatility
If the rung spacing is increased for adult use, then the ladder suits adult users, but it becomes difficult for children to climb
Solution Approach 1:
The ladder incorporates multiple sets of rungs at different spacing intervals along its length. Lower sections have closer spacing suitable for children, while upper sections have wider spacing appropriate for adults. This local variation in rung spacing allows different portions of the ladder to be optimized for different user groups without compromising overall versatility.

AI summary
Provided is a collapsible portable climbing net, featuring a left and right lateral pole, each comprising separable or connectable segments. The top pole connects the upper segments of the lateral poles, while the bottom pole connects the lower segments. A net is secured between the lateral poles and the top and bottom poles. The design allows for folding the lateral poles for compact storage, passing the poles through collars for easy assembly, and includes additional segments connected by connectors. The top and bottom poles are pivotally connected, enabling the net to be folded compactly.
