Amorphous Solid Aerosol Material for High Caffeine Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current liquid vaping delivery systems have limited solubility for caffeine, making it difficult to deliver high levels of caffeine effectively.
Innovation Solution
An aerosol-generating material comprising 10-50 wt% caffeine, 15-60 wt% gelling agent, and 10-50 wt% aerosol-former material, which forms an amorphous solid that can be heated to produce an inhalable aerosol, allowing for higher caffeine delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If liquid vaping delivery systems are used, then the system is simple and easy to operate, but the caffeine solubility is limited and cannot deliver high levels of caffeine
Solution Approach 1:
The patent changes the physical state of the caffeine delivery system from liquid to amorphous solid form. This parameter change enables the incorporation of high levels of caffeine (10-50 wt%) that would be insoluble in liquid vaping systems, directly resolving the solubility limitation while maintaining effective caffeine delivery
Solution Approach 2:
The patent creates a composite amorphous solid material comprising caffeine (10-50 wt%), gelling agent (15-60 wt%), and aerosol-former material (10-50 wt%). This composite structure allows caffeine to be embedded in a solid matrix that can be heated to release aerosol, overcoming the solubility constraints of liquid systems while enabling high caffeine content
2Quantity of substance
If high levels of caffeine are incorporated, then the caffeine delivery is improved, but the solubility limitations in liquid systems prevent effective delivery
Solution Approach 1:
By transitioning from liquid to amorphous solid state, the system can reliably incorporate and deliver high caffeine content (10-50 wt%) without the solubility limitations that plague liquid systems. The amorphous solid form ensures consistent caffeine release upon heating
3Quantity of substance
If traditional liquid vaping systems are used, then the device complexity is low, but the caffeine delivery capability is insufficient
Solution Approach 1:
The patent employs a composite amorphous solid material with three key components: caffeine (10-50 wt%), gelling agent (15-60 wt%), and aerosol-former material (10-50 wt%). This composite approach enables high caffeine delivery capability while maintaining a relatively simple heating device structure, as the complex functionality is embedded in the material itself rather than the device
