Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If online laser drilling is used to perforate the hollow support segment to form ventilation pores, then air introduction and cooling effect are improved, but the requirements on pipe-wall material and thickness increase, and manufacturing complexity increases
Solution Approach 1:
The hollow support segment pipe wall is designed with inherent porous structure, allowing air to pass through without requiring laser drilling or physical perforation. This porous material approach provides natural ventilation while simplifying the manufacturing process and reducing requirements on material thickness and laser power.
2Quantity of substance
If online laser drilling is used to form ventilation pores, then air introduction is improved, but laser power requirements increase and manufacturing reliability decreases
Solution Approach 1:
The pipe wall is manufactured with inherent porous structure that provides consistent air permeability without requiring post-manufacturing perforation processes. This eliminates laser drilling variability and power requirements, improving manufacturing reliability while maintaining adequate air introduction.
3Speed
If ventilation pores are formed by punching through the hollow support segment and wrapping papers, then air introduction speed is improved, but air-smoke mixing becomes uneven and smoking quality deteriorates
Solution Approach 1:
The tipping paper is designed with selective permeability - the portion covering the hollow support segment is impermeable to prevent direct air entry, while the portion at the distal end is permeable to allow controlled air introduction. This creates localized air entry points that improve mixing uniformity while maintaining adequate air introduction speed.
Solution Approach 2:
The permeable portion of the tipping paper acts as an intermediary layer between the external environment and the smoke flow path. It controls and distributes air entry along the distal portion of the hollow support segment, creating more uniform air-smoke mixing compared to direct puncture holes.
4Strength
If the tipping paper fully wraps the hollow support segment, then structural integrity is improved, but air permeability becomes fixed and cannot be adjusted for different smoking conditions
Solution Approach 1:
The tipping paper is designed with different permeability properties at different locations - impermeable at the proximal portion for structural support, and permeable at the distal portion for air introduction. This localized differentiation provides both structural integrity and adjustable air permeability.
Solution Approach 2:
The system allows dynamic adjustment of air permeability by modifying the length or permeability characteristics of the distal portion of the tipping paper. This enables adaptation to different smoking conditions while maintaining overall structural integrity through the proximal impermeable portion.
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
The solution enables flexible control of air permeability and volume, improving smoke quality and consistency by ensuring even mixing of air and smoke, thus addressing the limitations of fixed air introduction methods.
Implementation Method 1
the pipe wall 21 itself has a permeability function; there are ventilation pores inside the pipe wall 21, outside air can enter the pipe cavity 22 through the ventilation pores inside the pipe wall 21
Implementation Method 2
the pipe wall 21 is molded by particles adhesion and extrusion, the voids among the particles after molding are used as the ventilation pores
Implementation Method 3
the shaping paper 4 is permeable, while the tipping paper 5 is impermeable, the length of the tipping paper 5 is adjustable... ensuring even mixing of air and smoke
