Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing bibs do not effectively protect clothing from ash generated by smoking and lack features for secure fitting during use.

Innovation Solution

A fire retardant bib with weighted members and tethers for securing to the user, combined with a flexible fabric and a pocket for ash containment, designed to cover the torso and inhibit ash fall.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a bib is designed to cover the torso to inhibit ash fall, then protection effectiveness is improved, but the bib may slip or fail to stay positioned properly

Engineering Contradiction:

Improveash fall protectionVSAvoidbib positioning stability

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

Weighted members are attached to the bib to provide downward force that counteracts the upward movement and slipping of the bib during smoking activities, ensuring the bib remains positioned to protect clothing from ash fall

Inventive Principle:

Principle #8Anti-weight (Counterweight)

Solution Approach 2:

Tethers extend from the bib to anchor points on the user's clothing or body, adding a dimensional constraint that prevents the bib from moving in unwanted directions while maintaining its protective coverage

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Reliability

If weighted members and tethers are added to secure the bib, then bib positioning stability is improved, but device complexity increases

Engineering Contradiction:

Improvebib positioning stabilityVSAvoidbib structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The securing system is divided into separate components: weighted members attached to the bib body, and tethers connecting the bib to anchor points, allowing each component to be optimized independently and simplifying the overall assembly

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The weighted members automatically provide the necessary downward force to maintain bib position without requiring active adjustment or control by the user, while the tethers passively constrain bib movement through their geometric arrangement

Inventive Principle:

Principle #25Self-service

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

Effectively prevents ash from soiling clothing while ensuring secure fit and convenience for smokers.

Implementation Method 1

The bib has a pair of weighted members... The weighted members facilitate securing the bib to the person by weighing the bib downwardly onto the person

AI summary

A fire retardant bib assembly for being wearable around a neck of a person who is smoking includes a bib being wearable around a neck of a person who is smoking and being elongated to cover a torso of the person to inhibit ash created by an article being smoked from falling onto clothing of the person. The bib comprises a flexible fabric composed of a fire resistant material. The bib has a pair of weighted members, a pair of tethers, and a pocket. The pocket is coupled to the bib and includes an open end.
