Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional heating methods are used in coating pans, then coating application is effective, but active ingredients cannot be used that cannot withstand high temperatures and energy consumption increases
Solution Approach 1:
The invention changes the temperature parameter from traditional heated conditions (50-60°C) to cold conditions (0-20°C). This parameter change allows heat-sensitive active ingredients to be used in the coating without degradation, directly resolving the contradiction between temperature requirements and active ingredient versatility
Solution Approach 2:
Instead of heating the active ingredients and coating materials as in traditional methods, the invention inverts the approach by cooling the coating pan and using cold spraying techniques. This inversion eliminates thermal exposure to active ingredients while maintaining effective coating application
2Ease of manufacture
If traditional heating methods are used in coating pans, then coating application is effective, but energy consumption increases
Solution Approach 1:
The invention replaces the thermal field (heating system) with a mechanical field (cold spraying system). By using mechanical spray application at cold temperatures instead of thermal processing, the method eliminates the need for heating energy while maintaining coating effectiveness
Solution Approach 2:
Changing the temperature parameter from heated to cold conditions eliminates the need for energy-intensive heating equipment and operations, directly reducing energy consumption while preserving coating application capability
3Productivity
If gummy candy cores are processed in coating pans, then coating can be applied, but cores easily deform and batch size must be limited
Solution Approach 1:
The invention applies preliminary freezing to the gummy candy cores before coating application. This pre-treatment increases the cores' structural rigidity and resistance to deformation, allowing them to withstand the coating process even in larger batches without losing their shape
Solution Approach 2:
The invention utilizes the phase transition of water in gummy candy cores by pre-freezing them. This phase change from liquid to solid water increases the mechanical strength and dimensional stability of the cores, preventing deformation during subsequent coating operations
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
Enables the use of all active ingredients without thermal degradation, reduces production costs, and allows for larger batch processing of gummy candy cores, resulting in a more economical and versatile pharmaceutical product preparation.
Implementation Method 1
the introduction of hot air inside the coating pan promotes the evaporation of the solution leaving a hard, thick and resistant coating on the core
Implementation Method 2
it may be convenient for the gummy candy (11) to be pre-frozen, so that larger quantities of cores (1) are processed simultaneously (1)
