Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tobacco smoking devices, such as water pipes, are limited by the volume of cooling liquid, requiring frequent replacement and inadequate heat insulation, leading to inefficient smoke cooling and user discomfort.
Innovation Solution
Implementing a smoking apparatus with a thermally insulated chamber and a vacuum barrier to reduce heat migration, using a pressure reduction path to draw smoke through a cooling liquid, and incorporating a detachable mouthpiece for extended smoke cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the volume of cooling liquid is increased in traditional water pipes, then the duration of cool smoke is extended, but the device complexity and manufacturing difficulty increase due to the narrow mouthpiece diameter
Solution Approach 1:
The patent transitions from a one-dimensional narrow mouthpiece to a three-dimensional double-walled vessel structure. The inner wall contains the cooling liquid while the outer wall provides structural support and insulation, creating additional spatial dimensions that allow large cooling liquid volume without increasing mouthpiece complexity.
Solution Approach 2:
The inner wall containing the cooling liquid is nested within the outer wall structure. This nested configuration allows the cooling liquid to be contained in an internal chamber formed by the double-walled structure, maximizing the use of internal space for cooling purposes.
2Duration of action of stationary object
If heat insulation is improved in traditional water pipes, then smoke temperature reduction is maintained longer, but the device complexity increases
Solution Approach 1:
The double-walled structure functions as a composite thermal insulation system. The air gap between the inner and outer walls acts as an insulating layer, reducing heat transfer to the external environment and maintaining cooler smoke temperature for extended periods.
Solution Approach 2:
The patent extracts the insulation function from the mouthpiece structure and implements it through the double-walled vessel design. The thermal insulation is achieved through the separated inner and outer walls with an air gap, rather than adding insulation layers to the traditional single-walled mouthpiece.
3Quantity of substance
If the mouthpiece diameter is increased to accommodate more cooling liquid, then the cooling capacity is improved, but the portability and ease of operation deteriorate
Solution Approach 1:
The inner wall is nested within the outer wall, creating an internal chamber that holds the cooling liquid. This nested design allows the vessel to accommodate a large volume of cooling liquid while maintaining a compact external footprint suitable for portability.
Solution Approach 2:
The patent uses vertical stacking of the double-walled structure to increase cooling liquid capacity rather than increasing horizontal diameter. The tall, narrow profile of the vessel allows sufficient cooling liquid volume while maintaining ease of handling and portability.

AI summary
A method and apparatus for cooling smoke wherein a cooling liquid is introduced into a chamber. The chamber includes a containment wall and the method provides for reducing the thermal migration of heat across the containment wall from an outside environment into the chamber. Smoke is received through a stem that protrudes into the cooling liquid. By reducing the pressure applied to the surface of the cooling liquid, through a pressure reduction path, the smoke is drawn downward through the stem into the cooling liquid, where is allowed to bubble up to the surface and enjoyed as cold smoke by a tobacco user.
