Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carriers for toting persons and objects on the back often compromise on aspects like ease of use, weight, size, strength, carrying capacity, comfort, portability, and cost, lacking a balanced synergy among their components.
Innovation Solution
A collapsible carrier with a frame assembly and shoulder harness, featuring a hinged second frame member and supportive contact portion, allowing for secure carrying of cargo and passengers while being adjustable and compact for storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the carrier uses a rigid frame structure to ensure strength and carrying capacity, then the structural strength is improved, but the portability and ease of stowage deteriorate due to increased weight and size
Solution Approach 1:
The frame is divided into multiple members (first frame member, second frame member, third frame member) connected by hinges, allowing the structure to be segmented and reconfigured. This segmentation enables the frame to maintain strength when assembled while allowing disassembly or collapse for improved portability and storage.
Solution Approach 2:
The frame members are connected through hinges that allow relative movement between them, transforming the rigid static structure into a dynamic one. This dynamic connection enables the frame to adapt its configuration - maintaining structural integrity during use while allowing collapse or disassembly for storage, thus resolving the contradiction between strength and portability.
2Ease of operation
If the carrier uses a hinged frame design to improve collapsibility and storage efficiency, then the ease of stowage is improved, but the structural strength and stability may deteriorate
Solution Approach 1:
Multiple frame members are merged through hinge connections to form a unified structural system. The first frame member, second frame member, and third frame member work together as an integrated assembly, where the hinges serve as both connection points and structural elements, maintaining stability while enabling collapse functionality.
Solution Approach 2:
The hinge connections are pre-configured in the frame members to allow controlled movement and collapse. The mounting plate and hinge assembly are designed in advance to provide predetermined pivot points and movement paths, ensuring that when the frame is collapsed for storage, the structural integrity is maintained through the pre-planned hinge mechanics.
3Strength
If the carrier uses more frame members and hinge connections to improve carrying capacity and weight distribution, then the carrying capacity is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The hinge connections serve multiple functions: they connect frame members to form the structural assembly, enable relative movement for collapse functionality, and provide pivot points for load distribution. The mounting plate similarly serves both as a structural support element and as a connection interface for the hinge assembly, reducing the need for separate components and simplifying the overall device.
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 carrier provides a high level of user benefit by achieving synergy among its components, ensuring ease of use, comfort, and strength while being portable and cost-effective, with the hinged design allowing for efficient storage and secure weight distribution.
Implementation Method 1
The loop is configured to include a portion that contacts the first frame member when the second frame member is pivoted to an extended position with respect to the first frame member sufficiently to limit the span of travel of the second frame member with respect to the first frame member by such contact, such portion also providing supportive force for weight present on the framework when the second frame member is in an extended position

AI summary
Provided herein are articles useful for carrying and toting various articles, in addition to persons. One of the members of a frame assembly having two members hingedly connected to one another is secured to a shoulder harness, enabling the articles to be worn on the back of a user. A frame member having a seat or cargo grill or other framework is pivotable to an extended position, the pivotal travel of which is limited by the configuration of a loop and its orientation with respect to its contact with the other frame member, which contact simultaneously serves to provide force for supporting mass present on the seat or cargo grill or other framework. The frame assembly members are contoured to conserve space when stored, when the frame members are in a retracted position with respect to one another.
