Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing transformer devices require a robust frame body to support the weight of the transformer during lifting, leading to increased manufacturing costs.
Innovation Solution
A transformer device design that includes a suspension tool attachment unit connected to the core, allowing the weight of the transformer to be exerted on this unit during lifting, eliminating the need for a frame around the transformers, and incorporating a frameless structure with air flow openings for improved cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a highly rigid frame body is used to support the transformer weight, then the structural strength is improved, but the manufacturing cost increases
Solution Approach 1:
The patent extracts the weight-bearing function from the frame body and transfers it to the suspension tool attachment unit connected to the core. This allows the frame body to be simplified and eliminates the need for high rigidity in the frame, thereby reducing manufacturing cost while maintaining structural strength through the dedicated suspension unit.
2Stability of the object's composition
If a frame body surrounds the transformer stack, then the structural stability is improved, but the device complexity increases
Solution Approach 1:
The patent removes the enclosing frame body structure and retains only the essential suspension function through the attachment unit connected to the core. This extraction eliminates the complex frame surrounding the stack while maintaining structural stability through the dedicated suspension mechanism.
3Reliability
If the suspension bolts are firmly connected to the frame body, then the lifting reliability is improved, but the manufacturing cost increases
Solution Approach 1:
The patent extracts the suspension function from the frame body connection and creates a dedicated attachment unit directly connected to the core. This dedicated unit provides reliable lifting connection without requiring firm integration into a complex frame structure, thereby reducing manufacturing cost while maintaining lifting reliability.

AI summary
A transformer device includes: a transformer including a core and a coil; a suspension tool attachment unit disposed above the coil and connected to the core; and a cover body having an internal space and connected to the suspension tool attachment unit. A suspension tool for suspending the transformer device including the transformer and the cover is attachable to the suspension tool attachment unit. The cover body is provided with: a first opening located below a first phase transformer and allowing communication between the internal space and a space outside the internal space; and a second opening located above a third phase transformer and allowing communication between the internal space and the space outside the internal space. An air flow is formed such that air flows into the internal space through the first opening and is discharged to the space outside the internal space through the second opening.
