Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vape pens suffer from uneven heat distribution and liquid distribution, leading to inconsistent vaporization and potential inhalation of liquid droplets or diluted flavor.
Innovation Solution
A vape pen design featuring a heating element with a wire mesh composed of hexagon-shaped structures and electrical leads, surrounded by a wicking unit, ensures even heat and liquid distribution through a lattice structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If liquid is not evenly distributed along the heating element, then liquid concentration varies, but vaporization quality deteriorates and liquid droplets may be inhaled
Solution Approach 1:
The heating element is divided into multiple independent heating zones with separate liquid inlets. Each zone has its own liquid delivery channel that directs liquid uniformly across the heating surface, preventing concentration variations and ensuring even vaporization throughout the entire heating element.
Solution Approach 2:
Different regions of the heating element are designed with customized liquid inlet positions and angles. The liquid delivery system adjusts the flow direction and distribution pattern for each local area to achieve uniform liquid coverage, preventing both droplet accumulation and insufficient vaporization in any region.
2Manufacturing precision
If liquid is vaporized/atomized too finely, then vaporization quality improves, but flavor is diluted
Solution Approach 1:
The heating element operates at optimized temperature parameters that balance vaporization efficiency with flavor preservation. The uniform heat distribution across multiple zones allows precise temperature control, achieving sufficient atomization for smooth vaporization while maintaining the concentration of flavor compounds in the vapor.
3Temperature
If heating element does not evenly distribute heat, then heat distribution varies, but vaporization consistency deteriorates
Solution Approach 1:
The heating element consists of multiple segmented heating zones, each independently controlled with uniform heat generation. This segmentation ensures that heat is evenly distributed across the entire surface, preventing hot spots and cold zones that would cause inconsistent vaporization.
Solution Approach 2:
Multiple heating zones are merged into a single integrated heating element structure that works in unison to provide uniform heat distribution. The coordinated operation of all zones ensures consistent temperature across the liquid contact surface, maintaining stable and consistent vaporization quality.
