Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closed cleaning chamber with complex loading/unloading procedures is used, then cleaning effectiveness is improved, but cycle time increases and productivity decreases
Solution Approach 1:
The cleaning chamber is divided into two separate parts: a stationary cleaning chamber and a movable receiving chamber. The receiving chamber can be quickly inserted and removed, allowing for rapid loading and unloading of workpieces while the cleaning chamber remains in place, thus reducing cycle time without compromising cleaning effectiveness.
Solution Approach 2:
The receiving chamber is designed to be movable rather than fixed, allowing it to be dynamically inserted and removed from the cleaning chamber. This dynamic design enables quick changeover and reduces the time required for loading and unloading operations.
2Manufacturing precision
If traditional alignment measures are used to center the workpiece, then positioning accuracy is improved, but device complexity increases
Solution Approach 1:
The inclined roller bodies are designed to automatically center the workpiece through gravity and geometry. When the workpiece is placed on the inclined rollers, it naturally settles into a centered position without requiring external alignment mechanisms, thus achieving positioning accuracy while keeping the device simple.
Solution Approach 2:
Complex mechanical alignment mechanisms are replaced by the inclined roller design that uses gravity and geometric principles to achieve automatic centering. This substitution eliminates the need for additional alignment devices while maintaining positioning accuracy.
3Ease of operation
If multiple roller bodies are used to center the workpiece, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The roller bodies serve multiple functions: they support the workpiece during loading, automatically center it through their inclined design, and can be adjusted radially to accommodate different workpiece diameters. This multi-functionality simplifies operation while the modular design keeps complexity manageable.
Solution Approach 2:
The roller bodies are designed with radial adjustability, allowing their position to be dynamically changed to match different workpiece sizes. This dynamic capability enhances ease of operation for various workpieces while the adjustment mechanism is integrated into the roller design rather than adding separate complex systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Achieves short cycle times and effective cleaning by simplifying workpiece handling and optimizing the cleaning process.
Implementation Method 1
the roller bodies are inclined relative to the vertical, onto which the workpiece is placed. Since the roller bodies are inclined relative to the vertical according to the invention, the typically rotationally symmetrical workpiece or workpiece holder is simultaneously centered without the need for additional measures to align the workpiece or for holders during rotation. Rather, the workpiece rests on the roller bodies, which are inclined relative to the vertical, due to its own weight.
Implementation Method 2
at least one pressure device for generating a cleaning air flow passed through openings in the cleaning chamber
