Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods lack an industrial process for generating substrates for aerosol generation devices with low dimensional variations, particularly for thin substrates like those with a flat plate shape, without manual intervention.
Innovation Solution
A method involving a rotating cutting wheel with multiple cutting dies that removes substrates from each die at a chosen instant, using either a biasing force or pressurized gas, and a conveyor system for collecting and lifting substrates, allowing for simultaneous parallel cutting and collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual cutting methods are used to generate substrates, then dimensional variations can be controlled, but productivity is low and manual intervention is required
Solution Approach 1:
The cutting wheel is divided into multiple independent cutting dies arranged circumferentially, each capable of cutting substrates simultaneously. This segmentation allows parallel processing of multiple substrates, dramatically increasing productivity while maintaining precision through standardized die designs
Solution Approach 2:
The patent replaces manual cutting operations with an automated rotating cutting wheel mechanism. The mechanical system uses a motor-driven rotation to automatically position and actuate multiple cutting dies, eliminating manual intervention while maintaining consistent cutting precision through controlled mechanical motion
2Productivity
If a rotating cutting wheel with multiple cutting dies is used, then productivity increases through parallel cutting, but device complexity increases
Solution Approach 1:
The rotating cutting wheel serves multiple functions: it holds multiple cutting dies, provides rotational motion for sequential cutting, positions substrates through gravity feeding, and enables parallel processing. This multi-functionality reduces the need for separate mechanisms, actually simplifying the overall device despite increased productivity
Solution Approach 2:
The system uses gravity to automatically feed substrates onto the cutting wheel and between cutting dies, eliminating the need for complex feeding mechanisms. The rotating wheel itself serves as both the cutting tool carrier and the positioning mechanism, reducing overall system complexity
3Manufacturing precision
If substrates are removed from cutting dies at a chosen instant, then dimensional precision is improved, but timing control complexity increases
Solution Approach 1:
The cutting wheel rotates at a controlled periodic speed, bringing each cutting die to a precise position where substrates can be removed at consistent intervals. This periodic motion ensures that substrates are cut and removed at optimal moments, maintaining dimensional precision through regular, repeatable cycles
Solution Approach 2:
The patent replaces complex electronic timing control with a mechanically synchronized system where the rotation of the cutting wheel itself provides the timing reference. Substrates are removed when naturally positioned by the wheel's rotation, using mechanical motion rather than electronic sensors or actuators for timing control
