Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vibrating ball mills face challenges in handling and securing grinding bowls, requiring screws or other fastening mechanisms, which complicate the process and may compromise operational safety.
Innovation Solution
A vibrating ball mill with a fastening unit that includes a prestressed cylinder and sleeve system, along with a positioning mandrel, allows for easy insertion and secure attachment of grinding bowls and lids without screws, utilizing a spring device for tension and a release mechanism for easy loading and unloading, enhancing operational safety and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If screws or other fastening mechanisms are used to secure grinding bowls, then the grinding bowls can be held securely in place, but the handling process becomes more complex and time-consuming
Solution Approach 1:
The patent removes the traditional screw fastening mechanism and replaces it with a spring-loaded clamp system. The clamp is pre-tensioned to automatically grip the grinding bowl upon insertion, eliminating the need for separate fastening operations while maintaining secure holding.
Solution Approach 2:
The spring clamp is pre-loaded with tension before the grinding bowl is inserted. This preliminary action ensures that as soon as the grinding bowl enters the receptacle, the clamp is already in position and applies securing force immediately, without requiring any additional fastening steps.
2Reliability
If traditional fastening mechanisms are used, then the grinding bowls can be secured, but the operational safety may be compromised due to improper fastening
Solution Approach 1:
The spring-loaded clamp system is self-actuating. When the grinding bowl is inserted into the receptacle, the clamp automatically engages and applies securing force through its pre-loaded spring mechanism. The system serves itself by converting the simple insertion motion into automatic clamping action, ensuring consistent and reliable securing without requiring operator skill or attention.
3Reliability
If screws or complex fastening mechanisms are used, then the grinding bowls can be attached securely, but the time required for loading and unloading increases
Solution Approach 1:
The spring clamp is pre-tensioned and positioned before the grinding bowl is inserted. This preliminary preparation ensures that the securing action occurs automatically during the insertion process itself, eliminating any separate fastening time. Similarly, removal is simplified by releasing the spring tension, allowing rapid extraction.
4Ease of operation
If a simple insertion method is used without fastening mechanisms, then the handling is easier, but the grinding bowls may not be securely held during operation
Solution Approach 1:
The patent extracts the complex screw fastening operation and replaces it with a spring-loaded clamp system that provides automatic securing. The user simply inserts the grinding bowl into the receptacle, and the pre-loaded spring clamp automatically engages to hold it securely, combining simple insertion with reliable holding.
Solution Approach 2:
The spring clamp system automatically performs the securing function upon insertion. The pre-loaded spring converts the insertion motion into automatic clamping action, ensuring the grinding bowl is securely held during operation without requiring any additional fastening steps or operator intervention.
