Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fully automatic dispensers are used to automatically measure ingredients, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
A scale serves as an intermediary device between the operator and the mixing bowl, providing precise weight measurements without requiring complex automated dispensing mechanisms. The scale mediates the measurement function, allowing simple manual operation while achieving accurate ingredient proportions.
Solution Approach 2:
The patent replaces complex mechanical automated dispensing systems with a simpler electronic scale-based measurement system. Instead of using automated pumps or dispensers, the system uses electronic weight sensing to measure ingredients, substituting mechanical automation with electronic measurement and manual pouring.
2Device complexity
If manual mixing methods are used with coarse measurement devices, then device complexity is reduced, but manufacturing precision deteriorates
Solution Approach 1:
Coarse mechanical measurement devices (such as graduated cylinders or visual estimation) are replaced with an electronic scale that provides precise digital weight readings. This substitution maintains simple manual operation while dramatically improving measurement accuracy and formulation precision.
Solution Approach 2:
The scale provides real-time weight feedback to the operator through a digital display, allowing precise control over ingredient addition. The feedback mechanism enables the operator to achieve exact target weights for each ingredient, ensuring consistent and accurate mixture formulations.
3Device complexity
If no monitoring system is implemented, then device complexity is reduced, but reliability of results deteriorates
Solution Approach 1:
The scale provides continuous weight feedback during the mixing process, allowing the operator to verify that each ingredient is added in the correct amount. This feedback ensures consistent and reliable mixing results by enabling real-time verification of ingredient proportions.
Solution Approach 2:
The system performs self-monitoring of ingredient weights without requiring external supervision or complex control systems. The scale automatically tracks and displays the weight of each ingredient as it is added, enabling the operator to self-verify accuracy and ensure reliable results.

AI summary
A blending method is described for preparing a blended mixture. The blending method for preparing a blended mixture, the method includes: providing a control system having at least a processor, a computer-readable memory, and a display, wherein the memory contains software configured to receive a recipe defining instructions for preparing a blended mixture using one or more blending materials and amounts for producing a batch size of the blended mixture on a scale; monitoring a weight on the scale as blending materials are added to a receptacle on the scale; and indicating on the display the amounts of the blending materials that have been added to the scale to prepare an amount of a custom blended mixture based upon the selected blending materials.
