Solution Overview
Problem
Vibration during stirring affects weight measurement in conventional stirring devices, necessitating increased reinforcement structures and weight, which complicates accurate measurement and operation.
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, utilizing the container and motor unit as reinforcing members, along with load cells for indirect weight measurement, forming a closed reinforced structure to minimize vibration impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the supporting structure of the heating kettle is strengthened to reduce vibration impact on weight measurement, then measurement precision is improved, but device weight increases
Solution Approach 1:
The patent combines the motor unit with the heating kettle by attaching it to the bottom part of the kettle, forming an integrated structure. The motor unit serves dual purposes: providing stirring power and acting as part of the supporting structure. This merging eliminates the need for separate reinforcement structures that would increase weight, while still achieving adequate vibration resistance for accurate weight measurement.
Solution Approach 2:
The motor unit is designed to perform multiple functions: it provides rotational power for stirring and simultaneously serves as a structural component that reinforces the supporting structure. By making the motor unit multi-functional, the patent avoids adding dedicated reinforcement structures that would increase device weight, while maintaining measurement precision.
2Strength
If additional reinforcement structures are added to support the stirring container, then structural strength is improved, but device complexity increases
Solution Approach 1:
The patent merges the motor unit with the heating kettle structure, attaching it directly to the bottom part of the kettle. This integration means the motor unit itself becomes part of the supporting structure, eliminating the need for additional separate reinforcement components and reducing overall structural complexity while maintaining adequate strength.
3Measurement precision
If the rotary operating part is attached coaxially to minimize vibration, then measurement precision is improved, but stirring efficiency decreases
Solution Approach 1:
The patent deliberately adopts an asymmetric configuration by attaching the motor unit at a slant rather than coaxially, with the rotational axis inclined downward toward the outside of the stirring container. This asymmetric attachment optimizes the stirring action and crushing effect while the integrated structure manages vibration differently than traditional coaxial designs.
Solution Approach 2:
The patent employs dynamic balancing through the integrated motor unit design, where the motor and rotary operating part are coaxially and integrally formed. This integral construction allows the system to dynamically manage vibrations during operation, maintaining measurement precision while preserving stirring efficiency through the optimized slanted configuration.

Function Achieved in This Case
This configuration strengthens the supporting structure while reducing the need for additional reinforcement, allowing accurate weight measurement during stirring without increasing the device's weight, thus preventing vibration from interfering with the measurement process.
Implementation Method 1
a weight-measuring instrument capable of indirectly measuring a change in weight of a stirring substance in the stirring container during a rotation operation of the rotary operating part/motor unit
