Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If starch moulding powder is used in the mogul technique, then gelatin products can be produced with typical texture, but the production process requires extensive space, high investment, and risks cross-contamination
Solution Approach 1:
The invention extracts and removes the starch moulding powder from the production system, replacing it with solid reusable moulds. This eliminates the source of cross-contamination and reduces the complexity of powder handling, drying chambers, and cleaning systems while maintaining product purity through the controlled casting process
Solution Approach 2:
The invention replaces the reusable starch moulding powder (which requires continuous cleaning and drying) with solid reusable moulds that can be easily cleaned and reused without extensive drying chambers, significantly reducing the production system complexity and space requirements
2Ease of manufacture
If starch moulding powder is used for casting, then gelatin products can be produced, but the drying time is very long (24 to 72 hours) requiring large drying chambers
Solution Approach 1:
The invention extracts the drying function from the moulding material itself. By removing the starch moulding powder and using solid moulds with the new casting compound formulation, the drying step is eliminated entirely, reducing drying time from 24-72 hours to a much shorter period and eliminating the need for large drying chambers
Solution Approach 2:
The invention changes the physical and chemical parameters of the casting compound by using high-molecular gelatin (at least 130 kDa) with specific proportions of sugar alcohols and glucose syrup. These parameter changes enable the casting compound to set properly in solid moulds without requiring the long drying time associated with starch moulding powder
3Productivity
If starch moulding powder is reused continuously, then production efficiency is maintained, but cross-contamination from previous products occurs
Solution Approach 1:
The invention extracts the contamination source by removing the starch moulding powder from the system. Solid reusable moulds replace the powder, eliminating the risk of cross-contamination while maintaining production efficiency through easy cleaning and reuse of the solid moulds
Solution Approach 2:
The invention replaces the continuously reused starch powder (which accumulates contamination) with solid moulds that can be easily cleaned and sanitized between product changes, maintaining productivity while ensuring product purity by preventing cross-contamination
4Loss of time
If high-molecular gelatin with specific proportions is used, then rapid solidification occurs without significant drying, but the casting compound formulation becomes more specific and constrained
Solution Approach 1:
The invention applies parameter changes by specifying high-molecular gelatin with a mean molecular weight of at least 130 kDa and defining precise proportion ranges for sugar alcohols (6-76 wt%) and glucose syrup (0-50 wt%). These parameter changes enable rapid solidification while the defined ranges provide sufficient formulation flexibility for different product requirements
