Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cargo carrying and holding devices are cumbersome to use and store when not in use, lacking ease of movement and storage due to their non-expandable designs.
Innovation Solution
A cargo carrying device configured to transform from a contracted orientation to an expanded orientation, utilizing four beams and legs with a center hub assembly, allowing for easy expansion and contraction, and an outer cover that forms walls and a bottom when expanded, enabling efficient storage and use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cargo carrying device is designed to be expandable and collapsible, then ease of storage and portability is improved, but structural complexity increases
Solution Approach 1:
The device is divided into four separate beams that can be independently positioned and connected. Each beam can be separately manipulated during expansion and contraction, allowing the structure to transition between compact and expanded states while maintaining manageable complexity through modular organization
Solution Approach 2:
The device incorporates dynamic transformation capability through rotational joints at the corners, enabling the beams to move between fixed and extended positions. This dynamic mechanism allows the structure to adapt its configuration from a compact stored state to an expanded cargo-carrying state, resolving the contradiction between ease of storage and functional capability
2Object-affected harmful factors
If the device is designed with an outer cover that wraps around beams and legs, then cargo protection is improved, but device complexity increases
Solution Approach 1:
An outer cover is employed to wrap around the beams and legs, forming protective sidewalls and a bottom wall. This flexible shell approach provides cargo protection while avoiding the need for rigid, complex enclosing structures, thus maintaining relative simplicity in the overall device design
3Adaptability or versatility
If legs are disposed outwardly from center hub assembly, then cargo holding capacity is improved, but storage space requirement increases
Solution Approach 1:
The legs are designed with dynamic positioning capability through rotational joints, allowing them to extend outwardly when cargo holding is needed and retract toward the center hub assembly during storage. This dynamic configuration enables the device to provide adequate cargo holding capacity while minimizing storage space requirements by collapsing to a compact form
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides a convenient and space-efficient solution for carrying and storing cargo, allowing for easy movement and storage, serving as a versatile solution for vehicle protection and cargo management.
Implementation Method 1
a first center hub assembly having a first hub portion, a second hub portion, and a guide; wherein the first hub portion is in rotational cooperation with each of the three legs at a first point proximate a second end of the first legs
Implementation Method 2
Each of the beams are configured disposed to form longitudinally extending corners of the cargo carrying device, upon the cargo carrying device being disposed in the expanded orientation, and to form an outer case enclosing the first center hub assembly and the legs, upon the cargo carrying device being disposed in the contracted orientation
Implementation Method 3
an outer cover configured to wrap about the beams and the legs and form a bottom wall, a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall, upon the cargo carrying device being disposed in the expanded orientation

AI summary
Presently provided is a cargo carrying device, an expandable wall support, and method. The cargo carrying device has one or two expandable wall supports configured to transform from a contracted orientation to an expanded orientation. The expandable wall support has legs disposed with a center hub assembly at one end and beams disposed at the other of the legs. Upon the expandable wall support being disposed in the contracted orientation, the legs are disposed substantially parallel with each other and the beams enclose the legs and the center hub assembly. Upon the expandable wall support being disposed in the expanded orientation, each of the beams is disposed to form a longitudinally extending corner and the legs are disposed to support a wall.
