Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mixers for fluid and non-fluid materials experience vibration issues, which are transmitted to the operator's hands, leading to reduced operability.
Innovation Solution
Incorporating vibration isolators between the mixer shaft and the grip handle to absorb and reduce vibrations, thereby minimizing their transmission to the operator's hands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mixer operates with direct connection between mixer shaft and grip, then the mixing function is effective, but vibration is transmitted to the operator's hands reducing operability
Solution Approach 1:
The patent introduces a vibration isolator as an intermediary component between the mixer shaft and the grip handle. This isolator absorbs and dampens vibrations generated during mixing operations, preventing them from being transmitted directly to the operator's hands while still allowing the mixer shaft to rotate and perform its mixing function effectively.
Solution Approach 2:
The patent extracts the vibration isolation function from the main mixer structure by adding a separate vibration isolator component. This allows the mixing mechanism to operate independently while the isolator specifically addresses the vibration transmission issue, separating the mixing function from the vibration problem.
2Object-affected harmful factors
If vibration isolators are added between mixer shaft and grip, then vibration transmission is reduced, but device complexity increases
Solution Approach 1:
The vibration isolator can be implemented using flexible rubber or elastomeric materials that provide vibration damping through their inherent viscoelastic properties. These flexible components can be simple rings, pads, or sleeves that fit between the mixer shaft and grip, providing effective vibration isolation without requiring complex mechanical structures.
Solution Approach 2:
The vibration isolator changes the mechanical parameters of the connection between mixer shaft and grip by introducing materials with specific damping characteristics. By selecting materials and geometries with appropriate stiffness and damping coefficients, the system achieves vibration reduction while maintaining the necessary structural integrity and rotational movement.

AI summary
A mixer is less likely to cause lower operability due to vibration. A mixer includes a body including a motor and an output shaft to output rotation of the motor, a mixer shaft connectable to the output shaft, a handle attached to the body and including a grip, and a vibration isolator between the mixer shaft and the grip.
