Solution Overview

Problem

Individuals working from ladders often face challenges in organizing and accessing their tools and small items efficiently, leading to reduced efficiency and inconvenience due to the difficulty in holding and manipulating these items while working.

Innovation Solution

A collapsible container system with a rigid wall and engagement mechanism that securely attaches to a ladder top, allowing easy access and organization of tools, featuring a zipper closure and a handle for easy transport.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If individuals carry tools and small items while working from a ladder, then they have access to their items, but it becomes inconvenient and reduces efficiency due to difficulty in holding and manipulating items

Engineering Contradiction:
Improveease of access to toolsVSAvoid工作效率
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent introduces a container as an intermediary system that attaches to the ladder, serving as a mediator between the worker and their tools. The container provides a stable platform for holding tools and small items, eliminating the need for the worker to manually hold and manipulate items while working at height, thus improving ease of operation and productivity

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If individuals organize tools and small items while working from a ladder, then items can be located easily, but it becomes inconvenient and reduces efficiency

Engineering Contradiction:
Improveease of locating itemsVSAvoid工作效率
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent segments the storage space into multiple compartments within the container that attaches to the ladder. Each compartment can hold specific types of tools or small items, creating an organized system where items are easily located and accessed. This segmentation allows workers to quickly find what they need without manually searching through a cluttered space, thereby improving ease of operation and maintaining productivity

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If a container is designed to be collapsible for easy transport, then portability is improved, but structural stability may be compromised

Engineering Contradiction:
Improveease of transportVSAvoidstructural stability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent employs a collapsible container design that can transition between a collapsed state for easy transport and an expanded state for stable storage. The container includes a bottom panel and side panels that can be folded together when not in use, and deployed to form a stable structure when attached to the ladder. This dynamic design allows the container to adapt its configuration based on whether it is being transported or is in use, resolving the contradiction between portability and structural stability

Inventive Principle:
Principle #15Dynamics

AI summary

In some embodiments, containers, bags, and systems are provided that are useful to organize tools and other items. A tool bag may include a container body including one or more woven panels, a bottom rigid member, and a rigid wall hingedly connected to the bottom rigid member, and an engagement mechanism attached to the rigid wall. The engagement mechanism may include a base panel riveted on the rigid wall, and one or more protrusions extending from the base panel. In some aspects, the one or more protrusions are configured to engage with one or more holder slots on a ladder top.
