Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools, such as those described in DE 10 2011 007 050 B4, can only exert forces in one direction and require coupling with the component to be loosened, limiting their effectiveness in applications like cleaning clogged slots in ball mills where forces need to be applied in both axial directions.
Innovation Solution
A hammer device with an impact mechanism that stores and releases impact force in both axial directions, using an impact force storage means like an elastomer body or metallic spring to convert kinetic energy from the axial direction into counter-axial direction, allowing for efficient cleaning of clogged slots without manual labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional hammer tool is used to clean clogged slots, then manual labor is required to remove clamping bodies, but the cleaning process becomes labor-intensive and time-consuming
Solution Approach 1:
The hammer device automatically generates impact forces in both axial directions through its internal mechanism, eliminating the need for manual intervention to change tool orientation or apply forces from different directions. The device serves itself by converting single-direction impact forces into dual-direction cleaning action through the elastic body and tool arrangement.
Solution Approach 2:
The hammer device dynamically adapts its force application by using an elastic body to store and release impact energy, enabling the tool to deliver impacts in both axial directions automatically. This dynamic mechanism allows the device to switch between pushing and pulling actions on clamping bodies without manual intervention.
2Productivity
If a conventional hammer tool is used, then only forces in one axial direction can be applied, but cleaning effectiveness is reduced
Solution Approach 1:
The elastic body acts as a dynamic energy storage element that captures impact forces in one direction and releases them in the opposite direction. This dynamic mechanism enables the hammer device to automatically apply forces in both axial directions, significantly improving cleaning effectiveness for slots blocked by clamping bodies.
Solution Approach 2:
The elastic body serves as an intermediary between the impact mechanism and the tool, converting single-direction impact forces into dual-direction force application. This intermediary element enables the tool to exert forces in both axial directions by storing and releasing elastic energy during the impact cycle.
3Reliability
If manual lever tools are used to remove clamping bodies, then the slots can be cleaned, but the process is time-consuming and may not always achieve desired cleaning results
Solution Approach 1:
The hammer device automatically performs the complete cleaning cycle by generating impact forces in both directions through its internal mechanism. The device self-regulates the force application and direction changes, ensuring reliable removal of clamping bodies without manual intervention, thereby achieving complete cleaning results consistently.
Solution Approach 2:
The hammer device applies periodic impact forces in alternating axial directions to progressively dislodge and remove clamping bodies from slots. This periodic dual-directional impacting ensures thorough cleaning by repeatedly pushing and pulling on obstructing materials until complete clearance is achieved.
