Solution Overview

Problem

Smokers who roll their own cigarettes face difficulties in securing a mouthpiece due to the need for precise diameter matching or the use of adhesives, which are cumbersome and inexact.

Innovation Solution

A cigarette mouthpiece with an adjustable diameter made from a flexible sheet of material that can be rolled into a truncated cone shape, allowing expansion to securely fit and lock onto a rolled cigarette without adhesives, enabling the user to roll cigarettes with more tobacco and easily adjust the mouthpiece's position for smoking.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If the mouthpiece diameter is fixed, then the manufacturing is simple, but it requires precise diameter matching with the cigarette which is cumbersome and inexact

Engineering Contradiction:

Improvemouthpiece manufacturing simplicityVSAvoidmouthpiece attachment ease

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The mouthpiece transitions from a fixed rigid structure to a dynamic adjustable structure. The flexible material allows the mouthpiece to change its diameter dynamically - contracting for insertion and expanding for secure attachment - thereby eliminating the need for precise pre-matching while maintaining manufacturing simplicity

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The mouthpiece diameter parameter is made variable rather than fixed. By using flexible material, the diameter can be adjusted within a range to match different cigarette sizes, converting a static parameter into a dynamic one that adapts to different conditions

Inventive Principle:

Principle #35Parameter changes

2Reliability

If adhesive is used to attach the mouthpiece, then the attachment is secure, but the process is cumbersome and takes time

Engineering Contradiction:

Improvemouthpiece attachment securityVSAvoidtime required for mouthpiece attachment

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The chemical bonding mechanism (adhesive) is replaced with a mechanical bonding mechanism. The flexible mouthpiece uses friction and elastic deformation to create a secure mechanical connection with the cigarette, eliminating the need for adhesive application and curing time

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The mouthpiece attaches itself to the cigarette through its own elastic properties without requiring external adhesive materials. The flexible material naturally conforms to the cigarette surface and secures itself through friction and elastic recovery, making the attachment process self-sufficient

Inventive Principle:

Principle #25Self-service

3Adaptability or versatility

If the mouthpiece diameter is adjustable, then it adapts to different cigarette sizes, but the structure becomes more complex

Engineering Contradiction:

Improvemouthpiece diameter adaptabilityVSAvoidmouthpiece structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mouthpiece is constructed from flexible material that can deform and adapt its shape. This flexible shell structure provides diameter adjustability without requiring complex mechanical components, maintaining structural simplicity while achieving versatility

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The mouthpiece structure is designed to be dynamic rather than static. The flexible material allows natural deformation and adjustment of diameter in response to insertion forces and cigarette dimensions, providing adaptability without adding mechanical complexity

Inventive Principle:

Principle #15Dynamics

AI summary

A cigarette mouthpiece is described. Embodiments of the cigarette mouthpiece include cigarette mouthpiece made from a strip of flexible material having a varying width. A width of the strip of flexible material can help determine a length of a user engagement portion and a cigarette engagement portion of the cigarette mouthpiece. The cigarette mouthpiece can have a substantially circular cross-sectional shape and a diameter of the cigarette mouthpiece can be adjustable. Typically, an outside diameter of the cigarette engagement portion can be altered to fit into differently sized rolled cigarettes.
