Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If water is added to chocolate dough to form a sugar framework for heat resistance, then heat resistance is improved, but dough viscosity increases significantly
Solution Approach 1:
The patent introduces an emulsion (water-in-oil or oil-in-water) as an intermediary carrier to transport water into the chocolate dough. This emulsion acts as a mediator that allows water addition without direct mixing of water and dough, thereby forming sugar framework for heat resistance while preventing significant viscosity increase through controlled water distribution.
Solution Approach 2:
The patent changes the physical state and distribution parameters of water by using emulsion form instead of direct addition. By controlling the emulsion composition, water content, and mixing conditions, the patent achieves heat resistance through sugar framework formation while maintaining dough viscosity within acceptable ranges for industrial production.
2Productivity
If glycerol or sorbitol is mixed into chocolate dough to replace water, then viscosity increase is reduced, but viscosity still increases significantly making industrial production difficult
Solution Approach 1:
The patent uses emulsion as an intermediary that distributes water or sugar solutions uniformly throughout the dough matrix. This mediated addition approach prevents localized concentration changes and excessive viscosity increases, making the process suitable for industrial-scale production while maintaining heat resistance properties.
Solution Approach 2:
The patent creates a composite system combining emulsion, water/sugar solution, and chocolate dough components. This composite approach allows controlled integration of water-based ingredients without direct mixing, achieving both viscosity control and heat resistance while enabling industrial production feasibility.
3Ease of operation
If a water-in-oil emulsion is mixed into chocolate dough, then water addition is facilitated, but viscosity still increases significantly
Solution Approach 1:
The patent optimizes parameters of the water-in-oil emulsion such as droplet size, emulsifier concentration, and oil-to-water ratio to control water distribution. By adjusting these parameters, the patent facilitates easy water addition while minimizing viscosity increase, achieving both operational ease and productivity requirements for industrial production.
