Solution Overview

Problem

Conventional hand pipe cases lack a closely fitted cavity for the bowl, leading to material spillage and are not heat-resistant, posing risks of damage and burns when storing a hand pipe post-combustion.

Innovation Solution

A hand pipe sleeve with a heat-resistant material and a well portion designed to closely fit around the bowl, featuring a tapered shape and adjustable slits for secure fitting and easy insertion/removal, along with a clip for hands-free carrying.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional hand pipe case is used, then the hand pipe can be stored, but the consumable material may spill out of the bowl and the case is not heat-resistant causing burns or damage

Engineering Contradiction:

Improveprevention of material spillage and heat protectionVSAvoidcase structure complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies a flexible heat-resistant material (such as silicone rubber or heat-resistant polymer) to form the sleeve body that closely fits around the hand pipe bowl. This flexible material prevents consumable material spillage while providing heat resistance, eliminating the need for complex rigid structures with separate heat-resistant components.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The patent uses composite material construction by combining heat-resistant properties with flexible characteristics in a single integrated material system. The heat-resistant flexible material serves dual functions of thermal protection and spill prevention, resolving the contradiction between reliability improvement and device complexity reduction.

Inventive Principle:

Principle #40Composite materials

2Reliability

If the sleeve fits tightly around the bowl, then material spillage is prevented, but insertion and removal of the hand pipe becomes difficult

Engineering Contradiction:

Improveprevention of material spillageVSAvoidinsertion and removal ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent incorporates a dynamic opening mechanism where the sleeve includes a movable section or flexible opening that can be temporarily expanded to facilitate hand pipe insertion and removal. After insertion, the sleeve returns to its tight-fitting state to prevent material spillage, thus resolving the contradiction between secure fitting and ease of operation.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent introduces an intermediary mechanism (such as a flexible flap or expandable section) that mediates between the tight-fitting requirement and the ease of insertion/removal. This intermediary element temporarily alters the sleeve's fit during insertion/removal operations and maintains the tight seal during storage.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Quantity of substance

If the hand pipe is stored in the sleeve after combustion, then the consumable material can be preserved, but heat transfer to the sleeve causes burns or damage

Engineering Contradiction:

Improvepreservation of consumable materialVSAvoidheat transfer causing burns or damage

Core Design Contradiction:

Quantity of substanceVSObject-affected harmful factors

Solution Approach 1:

The patent creates a thermally isolated environment within the sleeve using heat-resistant materials that act as thermal barriers. This inert thermal environment prevents heat transfer from the combusted hand pipe to the sleeve and surrounding materials, eliminating the harmful thermal effects while maintaining the preservation function.

Inventive Principle:

Principle #39Inert atmosphere (Inert environment)

Solution Approach 2:

The patent converts the harmful heat generated by combustion into a beneficial feature by using heat-resistant materials that can withstand and dissipate the heat safely. The heat-resistant property, which initially seems to be just a protective feature, actually enables the sleeve to actively manage thermal energy and prevent burns while preserving the consumable material.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

According to some examples, a hand pipe sleeve can include a body with a top end section and a bottom end section. In such examples, the bottom end section can include an opening. Additionally, the body of the hand pipe sleeve can include a sleeve well portion. The sleeve well portion can extend from the opening to the top end section. In some examples, the sleeve well portion can be dimensioned to be closely fitted around a bowl of a hand pipe when the hand pipe is inside the sleeve well portion.
