Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the conventional dry ice apparatus uses a water pump to supply hot water to generate fog, then the fog production can be controlled, but the amount of water fog released per unit time is limited and the device complexity increases due to external power requirements
Solution Approach 1:
The patent removes the water pump and external power supply from the system, extracting the harmful complexity while maintaining fog production capability through direct thermal conduction between dry ice and water in the tank
Solution Approach 2:
The system uses natural convection and thermal conduction without mechanical assistance. The water naturally circulates and contacts the dry ice, and the fog naturally rises and exits through the outlet, making the system self-sufficient without external power
2Area of stationary object
If the conventional dry ice apparatus operates for a long time to cover large stages, then the coverage area increases, but the water temperature gradually decreases reducing fog release efficiency
Solution Approach 1:
The patent ensures continuous effective thermal contact between water and dry ice through natural convection currents that continuously bring warmer water into contact with the dry ice, maintaining consistent fog production efficiency over extended operation periods
3Ease of manufacture
If the conventional dry ice apparatus sprays water fog to create cloud effect, then the visual effect is achieved, but water stains form on the stage increasing slip hazards
Solution Approach 1:
The patent converts the harmful water spray into beneficial rising fog by allowing the fog to generate and rise naturally through thermal buoyancy, preventing water from contacting the stage while maintaining the desired visual effect
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 machine produces a large amount of fog per unit time, prevents water stains, and enhances safety by eliminating the need for external power and reducing slip hazards, while maintaining consistent fog effects.
Implementation Method 1
a heating assembly disposed in the liquid containing space to heat the liquid
Implementation Method 2
Dry ice is solid carbon dioxide which can directly sublimate to gaseous phase when exposed to heat
