Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for arranging heat sinks in power conversion systems are complex, time-consuming, and expensive, requiring isolators, intricate fixtures, and tight tolerance requirements, which increase production costs and risk mechanical distortion.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional mounting structures with isolators are used to arrange heat sinks, then electrical isolation is achieved, but assembly complexity and manufacturing cost increase significantly
Solution Approach 1:
The patent merges the electrical isolation function and mechanical mounting function into a single integrated rib structure. The ribs are formed directly as part of the enclosure body, eliminating the need for separate isolators and mounting fixtures. This integration reduces assembly steps while maintaining both electrical isolation and mechanical support functions.
Solution Approach 2:
The rib structure serves multiple functions simultaneously: it provides electrical isolation between heat sinks and the enclosure, acts as a mechanical mounting structure for heat sinks, and facilitates heat dissipation through its geometry. This multi-functionality eliminates the need for multiple separate components.
2Strength
If conventional mounting structures with multiple fixtures are used, then structural strength is sufficient, but assembly time increases
Solution Approach 1:
The mounting structure is merged with the enclosure body through integrated rib formations. The ribs are formed directly as part of the enclosure structure, eliminating the need for separate mounting fixtures and reducing assembly operations to simple placement and engagement of heat sinks onto the ribs.
Solution Approach 2:
The rib structures are pre-formed as integral parts of the enclosure during enclosure manufacturing. This preliminary formation of mounting structures eliminates the need for on-site assembly of mounting fixtures, significantly reducing assembly time while maintaining structural integrity.
3Manufacturing precision
If tight tolerance requirements are imposed on mounting structures, then alignment precision is improved, but manufacturing cost and complexity increase
Solution Approach 1:
The rib structure serves as both the enclosure structural element and the mounting alignment feature. Since the ribs are formed integrally with the enclosure, their positions and dimensions are inherently controlled by the enclosure manufacturing process, eliminating the need for separate precision machining of mounting fixtures.
Solution Approach 2:
The alignment and positioning functions are merged into the rib geometry itself. The ribs are designed with specific dimensions and spacing that inherently provide alignment guidance for heat sinks, eliminating the need for separate alignment fixtures or tight tolerance requirements on separate components.
4Ease of operation
If separate diffusers are used for assembling fans and electronics components, then component mounting is achieved, but electrical isolation complexity increases
Solution Approach 1:
The enclosure body with integrated ribs serves as a universal mounting platform for both fans and electronic components. The ribs provide electrical isolation and mechanical support for all components mounted on the enclosure, eliminating the need for separate diffusers or isolation structures for different component types.
Solution Approach 2:
The functions of separate diffusers for fan mounting and electronic component mounting are merged into the single enclosure structure with integrated ribs. All components benefit from the same electrical isolation and mounting mechanism, simplifying the overall design and reducing the number of separate parts.
