Portable Storage Sled with Adjustable Frame and Ridges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable coolers face difficulties in transportation on soft surfaces like sand and snow due to ineffective wheels and lack of practical, adjustable storage solutions that securely hold the cooler.
Innovation Solution
A portable storage sled with adjustable elongated members and extension members that can collapse and expand to fit various sizes, featuring a scissor-type connector and ridges for securing equipment, allowing for secure transport on diverse surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wheels are used to transport cooler on hardened surfaces, then ease of transport is improved, but effectiveness on soft surfaces deteriorates
Solution Approach 1:
The sled features an adjustable frame structure that can dynamically change its dimensions. The elongated members are selectively adjustable outwardly and inwardly to adapt between different operational states, allowing the sled to optimize its configuration for either hard or soft surface transport conditions.
Solution Approach 2:
The sled allows modification of key geometric parameters including the distance between elongated members and the overall length of the frame. By changing these parameters, the sled can transform from a compact configuration for storage to an expanded configuration optimized for transporting coolers on various surface types.
2Reliability
If general purpose sled is used to transport cooler on soft surfaces, then effectiveness on soft surfaces is improved, but portability and storability deteriorate
Solution Approach 1:
The sled employs a dynamic, collapsible frame structure where elongated members can be selectively adjusted inwardly to a collapsed state for compact storage or outwardly to an expanded state for operational use, enabling easy portability while maintaining effectiveness on soft surfaces.
Solution Approach 2:
The sled's elongated members are designed to nest within each other when collapsed, similar to a nested doll structure. This allows the sled to reduce to a compact, portable size for storage and transport while expanding to full functional dimensions when needed for cooler transport.
3Ease of operation
If general purpose sled is used without securing means, then ease of use is improved, but stability of cooler positioning deteriorates
Solution Approach 1:
The sled incorporates localized securing features in the form of ridges positioned at specific locations on the elongated members. These ridges create designated mounting positions that locally enhance cooler stability without complicating the overall simple sled structure, allowing the cooler to be securely positioned at optimal locations.

AI summary
A portable storage sled for transporting equipment includes a first elongated member and a second elongated member. At least one connecting member joins the first elongated member to the second elongated member. Each of the first elongated member and the second elongated member includes an extension member that is selectively retractable and extendable therefrom. The first elongated member, the second elongated member, the first extension member and the second extension member include a plurality of ridges extending upwardly therefrom that form an equipment mount between which the equipment is situated. The portable storage sled is selectively adjustable in length and width so that equipment of various sizes can be situated thereon.
