Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-combustible aerosol provision systems face challenges in efficiently heating aerosol-generating materials without combustion, requiring innovative heating elements that can effectively insert into and heat these materials during use.
Innovation Solution
A helical heating element is inserted into the aerosol-generating material, either during manufacturing or as part of the device, which can be screw-like with a central shaft and a helical portion, allowing for efficient heating through induction or conduction methods, and can be designed to rotate for uniform heating and easy insertion/ejection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If a heating element is inserted into aerosol-generating material, then heating efficiency is improved, but insertion complexity increases
Solution Approach 1:
The heating element is designed with a helical or spiral curved geometry instead of a straight configuration. This curved shape allows the element to be screwed into the aerosol-generating material like a thread, providing self-retaining insertion while maintaining good thermal contact with the material, thus improving heating efficiency without requiring complex insertion mechanisms
Solution Approach 2:
The helical heating element design enables self-insertion through a screwing action into the aerosol-generating material. The threaded geometry provides automatic mechanical engagement and retention, eliminating the need for additional fastening components or complex insertion mechanisms, thereby reducing device complexity while maintaining effective heating
2Stability of the object's composition
If heating element rotates during use, then heating uniformity is improved, but mechanical complexity increases
Solution Approach 1:
The heating element is designed to rotate dynamically during use rather than remaining stationary. This rotation can be achieved through user manipulation or integrated with the actuation mechanism, allowing the helical element to twist and contact different portions of the aerosol-generating material, ensuring uniform heating throughout the material without requiring complex multi-element arrays
3Area of stationary object
If heating element length is increased, then heating coverage is improved, but insertion difficulty increases
Solution Approach 1:
The helical geometry of the heating element allows a longer element to be inserted more easily by providing a screwing action that engages with the aerosol-generating material progressively. The curved threaded shape distributes insertion force along the length of the element, reducing the mechanical difficulty of inserting longer elements while maintaining extensive heating coverage throughout the material
