Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Reactor designs face challenges in minimizing size while effectively suppressing leakage magnetic fluxes and ensuring heat dissipation, as complete shielding increases internal space and traps heat, leading to potential malfunction and deterioration.
Innovation Solution
A reactor design featuring a reactor main body with a core and coil, a casing with an open portion, a terminal stage that supports the conductor, and a shielding member integrally formed with the terminal stage to suppress magnetic flux leakage while maintaining the casing opening, allowing for compact size and efficient heat dissipation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the entire reactor main body is covered by a shielding member to suppress leakage magnetic fluxes, then magnetic flux leakage is reduced, but the internal space of the reactor increases and the external shape becomes large
Solution Approach 1:
The shielding function is segmented and applied only to specific areas where magnetic flux leakage occurs, rather than covering the entire reactor main body. The shielding member is positioned at the ends of the reactor to suppress leakage fluxes locally, reducing the overall volume required while maintaining effectiveness.
Solution Approach 2:
The shielding member is strategically placed at specific locations (ends of the reactor) where magnetic flux leakage is most problematic, rather than providing uniform coverage. This localized approach suppresses harmful leakage fluxes while minimizing the increase in reactor volume.
2Object-affected harmful factors
If the reactor main body is covered by the shielding member, then leakage magnetic fluxes are suppressed, but heat is trapped inside the shielding member causing deterioration
Solution Approach 1:
The shielding structure is segmented with openings that allow heat to escape while maintaining magnetic flux suppression in critical areas. The shielding member covers only portions of the reactor main body, creating localized shielding zones that do not completely enclose the heat-generating components.
Solution Approach 2:
Heat dissipation pathways are extracted and maintained by providing openings in the shielding member. These openings allow heat to be removed from the reactor interior while the shielding member continues to suppress magnetic flux leakage in the covered regions.
3Reliability
If a wide gap is provided between the reactor main body and the shielding member to ensure insulation distance, then insulation is maintained, but the internal space increases
Solution Approach 1:
The insulation distance requirement is applied partially - only in the specific regions where the shielding member is positioned close to the reactor main body. In other areas, different insulation arrangements or materials are used, allowing the shielding member to be placed closer and reducing overall internal space while maintaining sufficient insulation where critical.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design achieves a compact reactor size with effective heat dissipation and reduced risk of malfunction by integrating the shielding member with the terminal stage, eliminating the need for insulation distance and preventing heat trapping.
Implementation Method 1
a shielding member that is integrally formed with the terminal stage and suppresses the leakage of magnetic fluxes from the reactor main body while maintaining the opening opened
Implementation Method 2
magnetic fluxes generated when a current flows through the coil passes through the interior of the core
Implementation Method 3
when the reactor is actuated by flowing a current through the coil, heat is produced
