Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of electronic atomization devices faces challenges with high production costs and low reliability due to the need for multiple welding leads, which complicates the manufacturing process and increases the risk of manual operation errors.
Innovation Solution
The proposed solution involves optimizing the control circuit by reducing the number of welding leads from three to two by eliminating the need for a welding lead at the ground pin GND or power supply pin VDD, allowing for a more efficient connection between the control chip and peripheral modules, thereby simplifying the PCB layout and reducing production costs while maintaining device reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If three welding leads are used to connect control chip pins (VDD, AT, GND) to peripheral modules, then reliable electrical connection is achieved, but production cost increases and manufacturing complexity increases
Solution Approach 1:
The patent extracts and eliminates the ground pin GND connection from the control chip, reducing the number of welding leads from three to two. The control chip is redesigned to function with only VDD and AT pins connected to peripheral modules, removing the need for the GND welding lead and simplifying the manufacturing process while maintaining reliable electrical connections through the remaining pins.
Solution Approach 2:
The patent makes the control chip universally adaptable by designing it to function with reduced connection requirements. The control chip can operate with only two welding leads (VDD and AT) instead of three, allowing it to be universally applied in electronic atomization devices with simplified PCB layouts and reduced manufacturing complexity while maintaining full functionality.
2Reliability
If multiple welding leads are required for control chip connections, then complete electrical connectivity is achieved, but production cost increases
Solution Approach 1:
The patent extracts and removes the GND pin connection from the control chip design, reducing the number of required welding leads from three to two. This elimination of the GND welding lead directly reduces production costs associated with manual welding operations while maintaining complete electrical connectivity through the VDD and AT pins to peripheral modules.
3Reliability
If three welding leads are used for control chip connections, then full control functionality is achieved, but manual welding errors increase
Solution Approach 1:
The patent extracts and eliminates the GND pin welding requirement from the control chip assembly process, reducing the number of welding operations from three to two. This reduction directly decreases the opportunity for manual welding errors and improves manufacturing precision while maintaining full control functionality through the remaining VDD and AT pin connections to peripheral modules.
