Solution Overview

Problem

Traditional agility ladders are cumbersome to unravel and fold, wasting time for athletes and trainers and increasing the risk of tangling or knotting, which reduces their appeal for busy users.

Innovation Solution

A quick folding agility ladder design featuring rectangular frames connected by synthetic fabric rung sleeves, allowing for a quadrifolium configuration that facilitates easy stacking and unfolding without tangling, utilizing flexible wire frames and fabric sleeves for stability and ease of use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional agility ladders are used, then the ladder structure is simple and easy to manufacture, but the ladder tends to get tied up or twisted into knots and takes several minutes to unravel or fold

Engineering Contradiction:
Improveease of unraveling and foldingVSAvoidtime to set up and collapse
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The agility ladder is divided into multiple individual rungs that can move independently relative to each other. Each rung is connected to adjacent rungs through sleeves that allow independent movement, enabling the ladder to be quickly folded and unfolded without the entire structure becoming tangled together as a single unit.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The ladder transitions from a static, rigid structure to a dynamic, flexible structure where rungs can move independently within sleeves. This dynamic design allows the ladder to adapt its configuration during folding and unfolding operations, preventing it from getting stuck in tangled positions and enabling rapid setup and collapse.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If traditional agility ladders are used, then the structure is simple, but the ladder requires meticulous folding to avoid introducing hard to untangle knots or twists

Engineering Contradiction:
Improveease of foldingVSAvoidfolding configuration complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

By segmenting the ladder into independently movable rungs connected through sleeves, the complex folding process is broken down into simple individual rung movements. Each rung can be folded independently without affecting the others, eliminating the need for meticulous coordinated folding of the entire structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rungs are nested within sleeves that guide their movement during folding. Each rung fits within a sleeve structure that provides a defined path for insertion and removal, allowing rungs to be quickly nested within each other during folding without creating complex tangles or requiring precise alignment.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Reliability

If traditional agility ladders are used, then the materials are simple and cost-effective, but the ladder gets tied up or twisted into knots that are hard to unravel

Engineering Contradiction:
Improveresistance to tangling and knottingVSAvoidmanufacturing complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The ladder is segmented into discrete rungs and sleeves that function as separate components. This segmentation prevents the entire ladder from becoming a single tangled mass, as each rung can move independently within its sleeve without getting twisted with adjacent rungs, significantly reducing knotting and tangling issues.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Sleeves are introduced as intermediary components between adjacent rungs. These sleeves act as mediators that guide and constrain rung movement, preventing direct contact and potential tangling between rungs while still allowing the necessary flexibility for folding and unfolding operations.

Inventive Principle:
Principle #24Intermediary (Mediator)
