Equipment Transport Bag Assembly With Strap-Supported Transformer Lifting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional equipment containment bags for leaking or non-performing electrical transformers and other utility equipment fail to provide safe and effective shipping and storage due to leakage issues and undue stress on the bags during handling, not meeting regulatory standards.
Innovation Solution
The equipment transport bag assemblies feature an open-top bag with an equipment-handling assembly that includes load-bearing strap units to engage lifting appendages, distributing the primary lifting load away from the bag, ensuring safe containment and compliance with regulatory standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional containment bags are used for transporting leaking transformers, then the bags can contain the equipment, but the bags experience undue stress during handling and lifting operations
Solution Approach 1:
The lifting function is segmented from the containment bag by introducing separate strap units. The bag is divided into containment-only function, while lifting is handled by dedicated strap components that engage with lifting appendages on the equipment.
Solution Approach 2:
Strap units serve as intermediary components between the lifting appendages on equipment and the containment bag. These straps bear the primary lifting loads and transfer them to external lifting mechanisms, preventing direct stress on the bag structure.
2Strength
If the bag structure is strengthened to bear lifting loads, then the bag can handle equipment directly, but the complexity and cost of the bag assembly increases
Solution Approach 1:
The system is segmented into simple containment bag and separate lifting strap components. This allows the bag to remain structurally simple while lifting capability is provided by the attached strap units that engage with equipment lifting appendages.
Solution Approach 2:
The strap units serve multiple functions: they provide lifting capability, connect the equipment to the bag, and distribute loads away from the bag structure. This multi-functionality eliminates the need for a complex strengthened bag design.
3Ease of operation
If openings are provided in the bag for accessing lifting lugs, then equipment can be properly positioned, but moisture or contaminants can enter the bag
Solution Approach 1:
The strap units are pre-configured to engage with lifting appendages before the equipment is fully positioned in the bag. This allows lifting lugs to be accessed and engaged through the bag material without requiring large openings that would compromise containment.
Solution Approach 2:
The strap units act as intermediaries that penetrate or engage with the bag material to access lifting appendages. This allows lifting operation while maintaining the bag's protective barrier against moisture and contaminants.

AI summary
Equipment transport bag assemblies (20, 92, 98, 145, 152, 182) each including an upright, open-top, equipment-receiving bag (22, 110, 158) with associated equipment-handling assemblies (24, 92, 102, 164, 184). The assemblies (24, 92, 102, 164, 184) have load-bearing strap units (34, 114, 166, 186) operably associated with the transport bags (22, 110, 158) so that the strap units (34, 114, 166, 186) bear the primary loads during lifting and handling of the bag assemblies (20, 92, 98, 145, 152, 182).
