Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing aerosol provision devices for tobacco heating are limited by the need for a long printed circuit board (PCB) to accommodate electrical connectors and heater assemblies, leading to bulkier designs and increased susceptibility to water and dust ingress.
Innovation Solution
A compact aerosol provision device design featuring a single PCB with perpendicular portions, where the electrical connector is positioned on the side rather than the bottom, and through holes for secure coil attachment, reducing the device's length and enhancing durability while minimizing water and dust exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a long printed circuit board is used to accommodate electrical connectors and heater assemblies, then the device can house all necessary components, but the device becomes bulkier and more susceptible to water and dust ingress
Solution Approach 1:
The PCB is folded at a bend to position the electrical connector on the side of the device rather than extending the full length. This dimensional repositioning reduces the device's overall length while keeping all components accessible, thereby reducing volume without compromising reliability.
Solution Approach 2:
Instead of placing the electrical connector at the bottom end of a long PCB, the connector is repositioned to the side of the device through the PCB fold. This inversion of the conventional layout reduces the device's length and minimizes exposure to water and dust while maintaining electrical connectivity.
2Ease of operation
If a long printed circuit board is used to accommodate electrical connectors and heater assemblies, then all components can be housed, but the device length increases
Solution Approach 1:
The PCB is folded at a bend to reposition the electrical connector from the bottom end to the side of the device. This dimensional change makes the connector more accessible to users while simultaneously reducing the overall device length.
Solution Approach 2:
The electrical connector is repositioned from the conventional bottom placement to the side of the device through the PCB fold, improving accessibility while reducing device length.
3Reliability
If the electrical connector is positioned at the bottom of the device, then the PCB layout is simple, but the device is more susceptible to water and dust ingress
Solution Approach 1:
The PCB is folded at a bend to reposition the electrical connector on the side of the device. This dimensional change protects the connector from water and dust ingress while maintaining a relatively simple PCB manufacturing process through standard folding techniques.
