Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If handheld mixers with rotatable blades are used, then mixing speed can be increased, but mixing uniformity and consistency deteriorate due to technique dependence
Solution Approach 1:
The mixing container is designed to be self-contained with an integrated mixing blade and gear mechanism that automatically mixes the composition when the container is inverted, eliminating the need for external handheld mixers and technique-dependent manual operation
Solution Approach 2:
The mixing blade is designed to rotate dynamically when the container is inverted, utilizing the gravitational force and gear mechanism to create automated rotational motion that ensures consistent mixing without manual intervention
2Ease of operation
If manual mixing is performed in open containers, then ease of operation is improved, but contamination risk increases
Solution Approach 1:
The mixing container creates a closed, sterile environment that isolates the biological composition from external contamination sources while still allowing the mixing function to occur through inversion of the entire sealed container
Solution Approach 2:
The mixing function is extracted from external handheld devices and integrated directly into the sealed container itself, allowing mixing to occur within the closed sterile environment without requiring opening the container
3Productivity
If vigorous mixing is applied to achieve uniform dispersion, then mixing speed is improved, but damage to biological components increases
Solution Approach 1:
The gear mechanism is designed with specific gear ratios that control the rotational speed of the mixing blade, ensuring it rotates at an optimal speed that achieves uniform mixing while remaining gentle enough to preserve viable cells and biological components
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
Ensures consistent and uniform mixing of dry compositions with fluids, reducing contamination risks and preserving the integrity of biological components, particularly viable cells, by using a planetary gear system for rapid and gentle blending.
Implementation Method 1
The gear mechanism has at least one gear, each of the at least one gears is connected to or intermeshed with the internal gear of the base cap and the gear of the shaft end. The gear mechanism is external of the main housing and is held in the rotatable base cap. Rotation of the rotatable base cap drives the gear mechanism to rotate the mixing blade.
Implementation Method 2
The mixing blade has a plurality of prongs extending from a shaft. The prongs are in the mixing chamber and the shaft extends through an opening in the main housing to inside the rotatable base cap.
