Intersecting Support Panels for Quake-Resistant Power Converters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of stages in power conversion devices increases, the center of gravity also increases, leading to decreased stability and quake resistance, and existing solutions like precise brace structures are costly and complex to design and assemble.
Innovation Solution
A power conversion device with a base, stages, and support panels that are integrally formed to intersect, providing improved quake resistance while reducing manufacturing and assembly costs by eliminating the need for precise design and additional fixation points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If support members forming a brace structure are used to improve quake resistance, then the quake resistance of the power conversion device is improved, but the manufacturing cost and assembly cost increase due to precise design requirements
Solution Approach 1:
The support structure is segmented into multiple panels (first panel, second panel, third panel, fourth panel) that can be independently configured. Each panel provides support in specific directions, and they work together to form a comprehensive support system without requiring complex brace structures
Solution Approach 2:
The panels serve multiple functions: they provide mechanical support, distribute loads, and enhance quake resistance simultaneously. The same panel structure that supports the stage also contributes to overall structural stability and resistance against vibrations
2Power
If the number of stages is increased to achieve higher power conversion capacity, then the power conversion capability is improved, but the center of gravity increases leading to decreased stability
Solution Approach 1:
The support structure transitions from one-dimensional vertical support to two-dimensional panel-based support. By introducing panels that extend in multiple directions (first panel in first direction, second panel in second direction, etc.), the support system distributes loads across multiple dimensions, enhancing stability without limiting power conversion capacity
Solution Approach 2:
The panels are configured with different orientations and directions to create an asymmetric support structure that optimally counteracts the increased center of gravity. The first panel extends in a first direction, the second panel in a second direction, allowing the structure to adapt to the specific gravitational load distribution

AI summary
A power conversion device includes a base, a first stage, a first support portion, and a support member. At least one first power conversion unit is mounted on the first stage. The first support portion extends in a normal direction of the base and is fixed to the base and the first stage. The support member includes a first panel and a second panel. The first panel and the second panel are disposed on the base to support the first stage in the Z-axis direction. The first panel and the second panel are integrally formed to intersect with each other.
