Solution Overview

Problem

Existing vertically deployable storage devices are not practical for construction sites due to lack of transportability, robustness, and accessibility issues, as they require simultaneous actuation of unlocking mechanisms and lack external locking means, making them difficult to move and transport safely.

Innovation Solution

A storage device with a frame, rolling means, telescopic uprights, and external locking/unlocking means that function as both locking and actuating mechanisms, allowing for safe transport and easy deployment, featuring a U-shaped rod for horizontal translation and orifices on uprights for locking in compact and deployed positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If internal locking means are used inside the uprights, then the device can be locked in position, but the locking means become inaccessible in the event of failure and require complex actuation mechanisms

Engineering Contradiction:
Improvelocking reliabilityVSAvoidaccessibility of locking means
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The locking means are extracted from the internal structure of the uprights and repositioned on the external surface of the frame. This allows the locking mechanism to remain functional while becoming accessible for operation and maintenance. The locking means now include a locking element that can be manually actuated from outside the device structure.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

A rod element serves as an intermediary component that connects the external locking means to the telescopic uprights. This rod transmits the locking force from the externally accessible locking element to the uprights, enabling reliable locking while maintaining external accessibility for operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If simultaneous actuation of two separate actuating members is required for unlocking, then the locking mechanism can be secure, but the operation becomes complex and requires precise positioning

Engineering Contradiction:
Improvelocking securityVSAvoidsimplicity of unlocking operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

Two separate actuating members are merged into a single integrated locking element. This unified element can be actuated by a single user action while still engaging both uprights simultaneously, maintaining security while simplifying the operation to a single intuitive motion rather than requiring coordinated manipulation of two separate components.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If the device is designed to be mobile with rollers, then it can be moved on smooth surfaces, but it is not transportable and cannot be safely moved to different locations

Engineering Contradiction:
Improvemobility on smooth surfacesVSAvoidtransportability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The device incorporates a dynamic locking system that adapts to different operational states. During transport, the locking means secure the telescopic uprights in a fixed configuration, preventing accidental opening. When in use on smooth surfaces, the rollers enable mobility while the locking mechanism remains engaged to maintain structural integrity, thus achieving both mobility and transportability.

Inventive Principle:
Principle #15Dynamics

4Shape

If the locking means are internal to the device, then the structure can be compact, but the locking mechanism is inaccessible and difficult to maintain

Engineering Contradiction:
Improvecompact structureVSAvoidaccessibility for maintenance
Core Design Contradiction:
ShapeVSEase of repair

Solution Approach 1:

The locking means are extracted from the internal telescopic structure and repositioned on the external frame surface. This maintains the compact overall structure of the device while making the locking mechanism externally accessible for easy operation, inspection, and maintenance without requiring disassembly of internal components.

Inventive Principle:
Principle #2Taking out (Extraction)
