Adjustable Cavity Handheld Cigarette-Making Machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld cigarette-making machines are complex and expensive to manufacture and use, as they require adjustments in cavity length, tamper length, and throw distance to accommodate different tobacco-receiving portion lengths in cigarette tubes.
Innovation Solution
A handheld cigarette-making machine design that uses a single throw distance and tamper length, with an adjustable tobacco receiving cavity to accommodate two different tobacco-receiving portion lengths, featuring a sliding member with an adjustment mechanism and a pivoting top member for compressing tobacco, allowing for efficient filling of both shorter and longer cigarette tubes without altering the throw distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cavity length, tamper length, and throw distance are adjusted to accommodate different cigarette tube lengths, then the machine can fill both shorter and longer tubes, but the device complexity and manufacturing cost increase
Solution Approach 1:
The cavity length is made dynamically adjustable through a telescopic structure where the second cavity portion can move relative to the first cavity portion. This allows the effective cavity length to be changed to match different cigarette tube lengths without requiring changes to the tamper length or throw distance, thereby reducing overall device complexity while maintaining adaptability
Solution Approach 2:
The single telescopic cavity structure serves multiple functions: it can accommodate both shorter and longer cigarette tubes by adjusting its effective length, and it works with a fixed tamper length and fixed throw distance. This universal design eliminates the need for multiple specialized components, reducing manufacturing cost and complexity
2Adaptability or versatility
If multiple adjustable components are added to accommodate different tube lengths, then versatility improves, but ease of operation deteriorates due to multiple adjustments required
Solution Approach 1:
The telescopic cavity provides a single dynamic adjustment mechanism (moving the second cavity portion) that replaces the need for multiple static adjustments. The user only needs to adjust the cavity length to match the cigarette tube length, while the tamper length and throw distance remain fixed, significantly improving ease of operation
Solution Approach 2:
The cavity is segmented into a first fixed portion and a second movable portion. This segmentation allows the effective length to be adjusted by moving only the second portion, creating a simple single-step adjustment process rather than requiring multiple coordinated adjustments across different components
