Equipment Transport Bag With Aligned Lifting Strap Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional equipment transport bags face challenges in safely containing leaking or non-performing electrical equipment like transformers, which can leak hazardous chemicals, and require effective containment while minimizing stress on the bag structure due to the heavy nature of the equipment.
Innovation Solution
An equipment transport bag assembly with a bag and an equipment-handling assembly, featuring aligned strap and bag openings to receive lifting elements, allowing for the bag to be expanded around the equipment, with load-bearing strap units to handle the equipment's weight, while the bag itself bears minimal load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If conventional equipment transport bags use lifting loops to handle heavy equipment, then the equipment can be lifted and transported, but substantial stress is placed on the bag structure which may compromise safety and durability
Solution Approach 1:
The patent introduces an equipment-handling assembly with straps as an intermediary component between the lifting equipment and the bag. The straps are attached to the bag at specific attachment points that are structurally reinforced, allowing the straps to bear the substantial lifting loads while the bag structure itself experiences minimal stress. This mediator approach resolves the contradiction by separating the load-bearing function from the containment function.
Solution Approach 2:
The lifting function is segmented from the bag structure by using separate strap units that can be independently attached and detached. The bag structure is divided into load-bearing attachment points and the containment body, allowing each component to be optimized for its specific function without compromising the other.
2Ease of operation
If the bag structure directly supports heavy equipment during transport, then the equipment can be contained and moved, but the bag experiences substantial stress that may lead to failure or environmental contamination
Solution Approach 1:
The strap units serve as intermediaries that transfer the equipment weight to external lifting mechanisms rather than placing stress on the bag structure. The bag maintains its containment function while the straps handle the mechanical loading, thereby improving reliability without compromising ease of operation.
Solution Approach 2:
The bag structure is designed with specific local qualities at the attachment points where straps connect - these areas are reinforced to handle concentrated loads. The rest of the bag structure maintains its containment properties without unnecessary reinforcement, optimizing both containment effectiveness and structural reliability.
3Ease of operation
If lifting elements extend through the bag material, then equipment can be lifted, but this may compromise the leak-resistant and puncture-proof properties of the bag
Solution Approach 1:
The straps act as intermediaries that engage with lifting elements outside the bag, eliminating the need for lifting elements to penetrate the bag material. This maintains the integrity of the leak-resistant and puncture-proof bag structure while still enabling easy lifting operation through the external strap attachment points.

AI summary
An equipment transport bag assembly is operable to handle equipment having a lifting element. The bag assembly includes a bag and an equipment-handling assembly. The bag defines an interior configured to at least in part receive the equipment therein. The equipment-handling assembly includes a strap unit. The strap unit includes a strap attached relative to the bag. The strap defines a strap opening configured to receive the lifting element. The bag defines a bag opening configured to receive the lifting element. The strap opening and the bag opening are at least in part aligned relative to one another to facilitate contemporaneous extension of the lifting element through the strap and the bag.
