Solution Overview

Problem

Existing rolling beds for smoking articles are monobloc structures, making them inflexible and costly to adapt for different sizes or types of smoking articles, and often result in incomplete drying of glue during the rolling process, affecting product quality.

Innovation Solution

A modular rolling bed with independent, adjustable sectors that can be customized for different smoking article sizes and types, featuring a lead nut and screw system for height adjustment and a heating system to ensure proper glue drying, along with varying grip surfaces for optimal rolling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a monobloc rolling bed structure is used, then the structure is simple and easy to manufacture, but it cannot be adapted to different smoking article sizes and types without replacing the entire rolling bed

Engineering Contradiction:
Improveadaptability to different smoking article sizes and typesVSAvoidstructure complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rolling bed is divided into multiple independent adjustable sectors instead of a monobloc structure. Each sector can be individually adjusted in height and position to accommodate different smoking article dimensions, while the sectors remain part of a unified rolling bed assembly. This segmentation enables adaptability without requiring complete replacement of the rolling bed for different products.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a monobloc rolling bed structure is used, then manufacturing costs are reduced, but production costs increase when changing to different smoking article types

Engineering Contradiction:
Improveadaptability to different smoking article typesVSAvoidmanufacturing and changeover costs
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The rolling bed comprises multiple independent sectors that can be adjusted without replacing the entire structure. This reduces manufacturing costs compared to producing multiple complete rolling beds for different products, while still enabling adaptation to various smoking article types through sector adjustment.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rolling bed sectors are made dynamically adjustable through height adjustment mechanisms (screws, lead nuts) and positioning systems, allowing the same rolling bed to be reconfigured for different smoking article types without physical replacement, thereby reducing changeover costs.

Inventive Principle:
Principle #15Dynamics

3Manufacturing precision

If uniform pressure is applied across the rolling bed, then the structure is simple, but glue drying is incomplete affecting product quality

Engineering Contradiction:
Improveglue drying qualityVSAvoidpressure distribution complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

Each sector of the rolling bed can be independently adjusted in height and pressure application, allowing different regions of the rolling bed to apply different compressive forces tailored to local glue drying requirements. This ensures complete and uniform glue drying across the entire rolling surface while maintaining overall structural simplicity.

Inventive Principle:
Principle #3Local quality

4Adaptability or versatility

If the rolling bed height is fixed, then manufacturing is simpler, but different smoking article sizes cannot be accommodated

Engineering Contradiction:
Improveaccommodation of different smoking article sizesVSAvoidheight adjustment mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The rolling bed is segmented into multiple independently adjustable sectors, each with its own height adjustment mechanism. This allows different parts of the rolling bed to be adjusted to accommodate various smoking article sizes without requiring complex overall restructuring or complete replacement.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rolling bed incorporates dynamic height adjustment capabilities through mechanical mechanisms (screws, lead nuts, positioning systems) that allow each sector to be raised or lowered to match the dimensions of different smoking articles, providing versatility without excessive complexity.

Inventive Principle:
Principle #15Dynamics
