Solution Overview

Problem

Existing smoking article rollers lack a consistent and efficient method to produce uniform smoking articles of varying sizes, particularly for custom-blended tobacco or Cannabis joints, and there is no insert available to facilitate this process.

Innovation Solution

A removable insert with magnetic male and female ends is used in a roller to ensure consistent placement of smoking materials, allowing for easy extraction and assembly of smoking articles, which can accommodate different sizes and types of filters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed rolling mechanism is used, then the structure is simple, but it cannot accommodate smoking articles of different sizes

Engineering Contradiction:
Improveaccommodation of different smoking article sizesVSAvoidroller structure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rolling mechanism is divided into separate components: a fixed roller body and removable inserts. The inserts can be exchanged to accommodate different smoking article sizes, allowing the system to adapt to various dimensions without redesigning the entire roller structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The roller transitions from a static fixed structure to a dynamic configurable system by allowing users to remove and replace inserts based on the desired smoking article size, making the device adaptable to different requirements.

Inventive Principle:
Principle #15Dynamics

2Manufacturing precision

If manual rolling is used, then the device is simple, but consistency in smoking article production is poor

Engineering Contradiction:
Improveconsistency of smoking article dimensionsVSAvoidrolling mechanism complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The inserts are pre-configured with specific dimensions and features that ensure consistent smoking article production. By preparing the rolling surfaces and structures in advance on the inserts, the system achieves uniformity without requiring complex automated controls.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Different inserts provide different rolling parameters (dimensions, surface characteristics) to achieve consistent production of various smoking article sizes. Each insert is designed with specific parameters that optimize the rolling process for particular article types.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If the filter is integrated into the rolling mechanism, then assembly is automatic, but the filter cannot be easily removed or replaced

Engineering Contradiction:
Improvefilter assembly and removal easeVSAvoidmechanism complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The filter is separated from the main rolling mechanism and attached to the removable inserts. This segmentation allows the filter to be easily assembled with the insert and removed together as a unit, simplifying the operation without requiring complex integration mechanisms.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The filter assembly is extracted from the fixed roller structure and placed on removable inserts. This extraction enables easy removal and replacement of filters by simply detaching the inserts, avoiding the need for complex disassembly of the entire rolling mechanism.

Inventive Principle:
Principle #2Taking out (Extraction)

AI summary

A removable insert for a rolled smoking article includes male and female ends. The smoking article is rolled in a roller apparatus including first and second rollers rotatably mounted in a frame. The male insert end is configured for telescopic and magnetic interconnection with the female insert end whereby the female insert end can be extracted from the smoking article and replaced with a filter. The smoking article end opposite the filter end can be crimped to complete the smoking article production.
