Cigarette Casing Feed Mechanism for Hands-Free Tobacco Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal cigarette-making machines require manual positioning of cigarette casings, which is time-consuming and difficult for users with dexterity or vision impairments, limiting their ability to produce multiple cigarettes efficiently.
Innovation Solution
A cigarette filling apparatus with a casing hopper, dispensing chute, and oscillating member, coupled with sensors and motors, automatically positions and fills cigarette casings with tobacco, allowing for hands-free operation and simultaneous production of multiple cigarettes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual positioning of cigarette casings is used, then device complexity is reduced, but productivity decreases and ease of operation worsens for users with dexterity or vision impairments
Solution Approach 1:
The system uses sensors to detect when a casing is properly positioned and automatically triggers the filling process, allowing the machine to monitor and control its own operation without requiring manual intervention or activation by the user
Solution Approach 2:
The patent replaces manual mechanical positioning and activation with an automated system using sensors (optical or capacitive) to detect casing position and trigger the filling mechanism, eliminating the need for users to manually operate the device
2Productivity
If one cigarette is made at a time with full user attention required, then device complexity is reduced, but productivity decreases
Solution Approach 1:
The system maintains continuous operation by automatically detecting when casings are positioned and immediately triggering the filling process without requiring user intervention between cycles, enabling continuous production of multiple cigarettes
Solution Approach 2:
The patent implements a feedback mechanism where sensors continuously monitor the position of casings and provide signals to the control system, which automatically activates the filling mechanism when conditions are met, enabling uninterrupted continuous operation
3Loss of time
If manual positioning is required, then device complexity is reduced, but loss of time increases due to repeated manual intervention
Solution Approach 1:
The system prepares for the next filling cycle by having sensors ready to detect casing position in advance, and the automated trigger mechanism is pre-configured to immediately activate when a casing is detected, eliminating waiting time between operations
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus enables efficient and user-friendly cigarette production, reducing manual intervention and accommodating users with disabilities, by automating the casing placement and tobacco filling process.
Implementation Method 1
a mechanical oscillator driven by a first motor. The mechanical oscillator may include a linear cam interposed between the oscillating member and a cam follower. The cam follower may be coupled to a reciprocating truck configured for back-and-forth motion driven by the motor
Implementation Method 2
The mechanical oscillator may include a linear cam interposed between the oscillating member and a cam follower
