Asymmetric Susceptor Projections for Secure Embedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing non-combustible aerosol provision devices face challenges in maintaining the susceptor within the aerosol-generating material during use, leading to potential displacement or removal, which affects efficient heating and aerosol generation.
Innovation Solution
A susceptor designed with projections that provide lower resistance for insertion than removal, allowing it to be embedded within the aerosol-generating material, and capable of being heated by a varying magnetic field for efficient heat distribution, is used in conjunction with a method of manufacturing that ensures the susceptor is partially or fully embedded within the aerosol-generating material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the susceptor is designed with projections that provide lower resistance for insertion, then the ease of manufacture and assembly is improved, but the reliability of securing the susceptor within the aerosol-generating material deteriorates
Solution Approach 1:
The susceptor incorporates projections with asymmetric geometry where the insertion face is angled or rounded to facilitate easy insertion, while the removal face features barbs or hooked elements that engage with the aerosol-generating material to prevent removal. This asymmetric design allows one-way insertion while securing the susceptor in place during use.
Solution Approach 2:
The projections are designed to be flexible or deformable, allowing them to compress during insertion to reduce resistance, then expand or lock into position within the aerosol-generating material to provide secure retention. This dynamic behavior enables easy assembly while ensuring reliable securing during operation.
2Productivity
If the susceptor is fully embedded within the aerosol-generating material, then the heating efficiency and aerosol generation are improved, but the difficulty of removing or replacing the susceptor increases
Solution Approach 1:
The susceptor is designed as a segmented or modular component with distinct insertion and retention features. The projections act as separate engagement elements that can be deformed or disengaged independently, allowing the susceptor to be removed from the aerosol-generating material without damaging either component, thus enabling replacement while maintaining full embedding during use.
Solution Approach 2:
The projections incorporate elastic or flexible materials that allow temporary deformation during insertion to achieve full embedding for optimal heating, then maintain a locked position during use. For removal, sufficient force can deform the projections to release the lock, enabling susceptor replacement while preserving the benefits of full embedding during operation.
