Stacked Motor Starter Layout for Compact Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motor starters have complex internal layouts leading to excessive volume and unreasonable insulation arrangements.
Innovation Solution
A compact layout is achieved by stacking components such as a power supply board, insulating boards, and signal processing board within a housing, with insulating parts separating these components to improve insulation and reduce volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional layout is used between internal assembling plates, then the motor starter can be manufactured with standard design, but the volume becomes excessive and insulation arrangement becomes unreasonable
Solution Approach 1:
The patent transitions from a conventional planar layout to a three-dimensional stacked arrangement of circuit boards (power supply board, signal processing board, interface board) vertically positioned on the base plate. This dimensional change enables compact packaging while maintaining all necessary functional separations and insulation requirements, directly resolving the volume issue without sacrificing manufacturability
2Ease of manufacture
If conventional layout is used between internal assembling plates, then the motor starter can be manufactured with standard design, but the insulation arrangement becomes unreasonable
Solution Approach 1:
The patent introduces dedicated insulating boards positioned between different circuit boards (power supply board and signal processing board, signal processing board and interface board) to provide electrical isolation. These intermediary insulating components ensure proper insulation without complicating the manufacturing process, as they are standard elements integrated into the stacked configuration
3Volume of stationary object
If components are arranged in a compact stacked manner, then the volume is reduced, but the insulation arrangement becomes more complex
Solution Approach 1:
The patent combines multiple functions into integrated circuit boards (power supply board, signal processing board, interface board) that are vertically stacked with insulating boards between them. This merging approach consolidates what would otherwise require separate horizontal arrangements into a compact vertical stack, reducing volume while the insulating boards provide systematic isolation without adding proportional complexity
