Cruciform Carrier With Adjustable Belt for Varying Mat Diameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing carriers for rolled mats, such as yoga or gym mats, are cumbersome, difficult to use, and often allow the mat to unroll during transportation, especially when accommodating mats of varying diameters.
Innovation Solution
A cruciform carrier with a rigid spine and flexible belt, featuring magnetic or buckle fastening, allows for easy adjustment to fit different mat diameters and prevents unrolling, using a unitary silicone body with optional metal stiffening and adjustable straps for secure carrying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a fixed dimension cylindrical bag is used to carry the rolled mat, then the mat can be contained in a compact form, but the mat must be rolled very tightly and may not fit if it begins to unroll during insertion
Solution Approach 1:
The carrier transitions from a rigid fixed-dimension bag to a dynamic structure with a deformable belt that can expand and contract. The belt is deformable into a loop that can be opened for easy insertion of the rolled mat and then closed to secure it, allowing the carrier to adapt its volume to the mat's dimensions without requiring tight rolling
Solution Approach 2:
The carrier's dimensions are made variable through the deformable belt mechanism. The belt can be deformed from a closed loop state to an open state, changing the carrier's effective volume and opening to accommodate the rolled mat during insertion, then returning to a compact closed state for carrying
2Ease of operation
If a larger open top bag with shoulder strap is used, then the mat can be easily inserted, but the mat may unroll and become bulky and unsightly during transportation
Solution Approach 1:
The carrier uses a dynamic belt mechanism that can transition between open and closed states. During insertion, the belt is opened to allow easy access, then closed and fastened to securely hold the mat in a stable, compact configuration during transportation, preventing unrolling
Solution Approach 2:
The carrier design incorporates preliminary securing action through the fastening means on the belt. Before transportation begins, the belt is closed and fastened around the rolled mat, preliminarily securing it in place to prevent unrolling and maintain a neat appearance throughout the journey
3Stability of the object's composition
If loop straps with buckle or backpack clip are used, then the mat can be secured, but it is difficult to coordinate attachment of two individual loops without the mat becoming unrolled
Solution Approach 1:
The carrier merges two separate loop straps into a single integrated deformable belt structure. This unified belt can be easily opened, wrapped around the rolled mat as a single continuous action, and then closed and fastened using the fastening means, eliminating the coordination difficulty of attaching two separate loops while still providing secure stabilization
