Solution Overview
Problem
Vibration during stirring affects weight measurement in conventional stirring devices, requiring strengthened reinforcement structures and increased weight.
Innovation Solution
A stirring device with a stirring container supported by a device frame and a rotary operating part/motor unit attached at a slant, using the container and unit as reinforcing members, along with a weight-measuring instrument to indirectly measure weight changes, forming a closed reinforced structure that reduces the need for additional reinforcement and minimizes weight increase.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional stirring device with vertical cutter/motor attachment is used, then the structure is simple, but vibration during stirring affects weight measurement accuracy
Solution Approach 1:
The cutter/motor unit is attached at a slant angle rather than vertically, with the rotational axis inclined downward toward the outside of the stirring container. This asymmetric configuration changes the vibration characteristics during stirring, reducing the interference with weight measurement while maintaining effective stirring function.
2Strength
If reinforcement structures are added to support the stirring container, then structural stability improves, but device weight increases
Solution Approach 1:
The supporting stand is integrated with the reinforcement base, and both work together with the stirring container and cutter/motor unit to form a closed reinforced structure. This merging of components provides structural strength without requiring separate, additional reinforcement elements, thereby avoiding excessive weight increase.
Solution Approach 2:
The closed reinforced structure combines multiple components (stirring container, reinforcement base, supporting stand, cutter/motor unit) into a unified structural system that distributes loads and enhances overall strength without requiring heavy individual components.
3Measurement precision
If the cutter/motor unit is attached vertically, then the structure is straightforward, but vibration during rotation interferes with weight measurement
Solution Approach 1:
The cutter/motor unit is attached at a slant angle rather than vertically, with the rotational axis inclined downward toward the outside of the stirring container. This asymmetric configuration changes the vibration characteristics during stirring, reducing the interference with weight measurement while maintaining effective stirring function.
