Flexible Weight Sled for Compact Storage and Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weight sleds are typically rigid, making them difficult to transport and store, and they often lack flexibility in accommodating different weights and user preferences.
Innovation Solution
A flexible weight sled made from materials like nylon webbing or canvas, equipped with a weight strap for attaching removable weights and a rear weight strap for stability, along with a Y-shaped upper body pulling strap with adjustable handles for user comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid frame is used to carry and support weights, then structural strength and stability are improved, but ease of transport and storage deteriorates
Solution Approach 1:
The patent replaces the traditional rigid frame with a flexible sled body made from durable fabric or webbing material. This flexible construction allows the sled to be collapsed or rolled up for compact storage and easy transport, while still maintaining sufficient strength to support exercise weights through its flexible structure and attached weight straps.
2Stability of the object's composition
If a rigid frame is used to carry and support weights, then structural stability is improved, but ease of storage deteriorates
Solution Approach 1:
The flexible sled body constructed from durable fabric or webbing can be collapsed or rolled into a compact form for storage, eliminating the need for a rigid frame structure. The flexibility of the material allows it to be stored in small spaces while maintaining structural integrity during use through the attached weight straps and frame supports.
3Device complexity
If fixed weight attachment is used, then structural simplicity is improved, but adaptability to different weights deteriorates
Solution Approach 1:
The weight attachment system is divided into separate components: a flexible sled body, detachable weight straps, and interchangeable weight plates. The weight straps can be attached or detached from the sled body, and different weight plates can be swapped, allowing easy adaptation to different weight requirements without changing the entire sled structure.
Solution Approach 2:
The weight attachment system transitions from a fixed structure to a dynamic, adjustable configuration. The weight straps can be attached or detached, and the weight plates can be exchanged, allowing the sled to adapt to different weight requirements. This dynamic system maintains structural simplicity while providing versatility for different exercise needs.

AI summary
A flexible weight sled includes a main body member made from a flexible material, such as a nylon webbing, canvas, or the like. The main body member includes a weight strap and a rear weight strap that is used to attach one or more weights to the main body member in a removable manner. Two pairs of upper body pulling straps are attached to the front portion of the main body member, and in a preferred embodiment, the upper body pulling straps include a pair of handles on a distal end thereof. The weight sled may be folded or rolled up for purposes of storage and/or transport.
