PCB-Based Electronic Control Fixing for Airtight Compressors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for connecting and fixing a frequency inverter to an airtight compressor are inefficient, requiring multiple steps, using excessive cables and plastic materials, leading to increased production costs and time.
Innovation Solution
A system and method that eliminates the need for cables by using a printed-circuit board with resting means and external feed terminals, establishing direct contact with the compressor's fence and connector, and encapsulating the board within an outer housing for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are used for electric connection between the frequency inverter and the connector, then reliable electric connection is achieved, but production costs and assembly time increase due to welding or additional connectors
Solution Approach 1:
The patent extracts and eliminates the cable from the system by establishing direct electric connection between the frequency inverter and the compressor connector through the printed-circuit board, removing the intermediate cable component and its associated welding operations
Solution Approach 2:
The patent merges the electric connection function with the structural support function by integrating the connector directly onto the printed-circuit board, combining multiple functions into a single integrated structure
2Stability of the object's composition
If multiple assembly steps are used for fixing the frequency inverter to the airtight compressor, then secure fixation is achieved, but production time and complexity increase
Solution Approach 1:
The patent merges multiple assembly operations into a single integrated printed-circuit board structure that simultaneously provides electric connection, mechanical support, and fixation functions, eliminating the need for separate assembly steps
Solution Approach 2:
The printed-circuit board is designed to perform multiple functions simultaneously: electric connection through traces, mechanical support through its rigid structure, and fixation through integrated mounting features, making it a multi-functional component
3Reliability
If cables and additional connectors are used for electric connection, then reliable connection is achieved, but production costs increase
Solution Approach 1:
The patent removes the cable and additional connector components from the system, eliminating their associated costs while maintaining connection reliability through direct integration on the printed-circuit board
Solution Approach 2:
The patent uses the printed-circuit board's existing trace structure to create the electric connection path, replacing the need for separate cable and connector components with traces that are already part of the board's manufacturing process
