Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing coating systems face challenges in efficiently and flexibly charging workpieces, particularly cylindrical tools, for uniform coating, as they require easy insertion and removal while maintaining a defined position during the coating process, especially when electrical contacting is necessary.
Innovation Solution
A charging device with upright stands featuring vertically aligned openings and insert sleeves with cylindrical bores, allowing for easy insertion and removal of workpieces, and accommodating different diameters and lengths through interchangeable sleeves, which can be tilted and locked in place for secure holding, enabling flexible adaptation to various workpieces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If workpieces are held firmly in fixed holders during coating, then coating uniformity is improved, but insertion and removal become difficult
Solution Approach 1:
The holder is divided into a fixed body and a movable clamping element that can independently adjust. The clamping element can be inserted and removed separately from the workpiece while the holder body remains fixed, allowing easy operation without compromising the firm holding needed for uniform coating.
Solution Approach 2:
The holder incorporates a dynamic clamping mechanism that transitions between open and closed states. During loading, the clamping element is open to allow easy insertion; during coating, it closes to firmly secure the workpiece, ensuring both ease of operation and coating uniformity.
2Manufacturing precision
If specialized holders are designed for specific workpiece types, then holding precision is improved, but adaptability to different workpieces deteriorates
Solution Approach 1:
The holder is designed with adjustable parameters including variable clamping forces, adjustable clamping positions, and interchangeable adapter elements. This allows a single holder design to accommodate multiple workpiece types and sizes while maintaining precise holding for each specific application.
Solution Approach 2:
The holder incorporates adjustable parameters such as clamping force magnitude, clamping position along the workpiece, and angular orientation. These parameters can be modified to suit different workpiece geometries and coating requirements, providing both precision and versatility.
3Reliability
If complex locking mechanisms are used to secure workpieces, then workpiece security is improved, but device complexity increases
Solution Approach 1:
The locking function is extracted as a separate, simple cam-based mechanism independent of the holder body. This cam mechanism provides reliable workpiece security through a single rotational motion that engages a latch, avoiding complex multi-component locking systems while maintaining high reliability.
