Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a rotatable electric treatment unit is arranged in the treatment chamber, then cleaning and drying processes can be carried out effectively, but the power supply becomes complex and costly
Solution Approach 1:
The power supply arrangement is segmented into distinct components: a first coupling element on the shaft outside the chamber, a second coupling element inside the chamber, and separate supply lines. This segmentation allows the power connection to be established through discrete, manageable parts that can be independently positioned and connected, simplifying the overall power supply complexity while enabling effective treatment processes.
Solution Approach 2:
The coupling elements act as intermediaries between the power source outside the treatment chamber and the electric treatment unit inside the chamber. The first and second coupling elements provide a mediated connection that allows electrical power to be transmitted through the chamber wall without direct penetration, reducing the complexity of the power supply arrangement while maintaining effective treatment capability.
2Productivity
If the shaft is mounted rotatably to enable treatment unit rotation, then treatment effectiveness is improved, but the power connection stability becomes problematic
Solution Approach 1:
The power supply arrangement is designed to be dynamic rather than static. The coupling elements and supply lines are configured to accommodate the rotational movement of the shaft, allowing the system to adapt to changing positions while maintaining electrical connection. This dynamic design enables the shaft to rotate up to 360° or 720° without compromising power connection stability, thus maintaining both treatment effectiveness and connection reliability.
Solution Approach 2:
The system allows for changes in the angular position parameter of the shaft during operation. The power supply arrangement is designed to maintain electrical connection despite these parameter changes, with the coupling elements and supply lines configured to accommodate rotational movements of up to 360° or 720° while maintaining stable power transmission.
3Ease of manufacture
If a simple power supply arrangement is implemented, then cost-effectiveness is improved, but the ability to rotate the shaft without damaging power supply is limited
Solution Approach 1:
The power supply arrangement is divided into segmented components (first coupling element, second coupling element, supply lines) that can be independently manufactured and assembled. This segmentation enables a relatively simple and cost-effective implementation while still accommodating shaft rotation up to 360° or 720°, as each component can be designed to work independently with minimal complexity.
Solution Approach 2:
The patent replaces complex mechanical power transmission systems with a simpler electrical coupling system. Instead of using complex mechanical connections to transmit both mechanical and electrical power, the system uses separate electrical coupling elements that can accommodate rotation, simplifying the overall system while maintaining both cost-effectiveness and rotational capability.

AI summary
The invention relates to a treatment device for workpieces, having the following: a treatment chamber (1); a shaft (2) which extends through a wall of the treatment chamber (1) into the treatment chamber and which is mounted in a rotatable manner; an electric treatment unit (3) which is secured to the shaft (2); and a power supply arrangement (6) with a first supply line (61), an electric coupling (63, 64), a second supply line (62), and an actuating unit (7). The electric coupling (63, 64) has a first coupling element (63), which is secured to the shaft (2) outside of the treatment chamber (1), and a second coupling element (64). The first supply line (61) connects the electric treatment unit (3) to the first coupling element (63), and the second supply line (62) is connected to the second coupling element (64). The actuating unit (7) is designed to actuate the coupling (63, 64) in order to bring the second coupling element (64) into contact with the first coupling element (63) or release the second coupling element (64) from the first coupling element (63).
