Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing discharging devices for electrostatic charges from shafts are limited in their ability to form secure contact with shaft circumferences regardless of rotation direction and are not adaptable to shafts with varying diameters, as they rely on axial contact and specific circumference arrangements.
Innovation Solution
A discharging device featuring a bending-elastic conductor arrangement with carbon fiber conductors arranged transverse to the shaft, adjustable holder legs that pivot to adjust contact angle and distance, allowing tangential contact with the shaft circumference, and an electrically conductive or non-conductive pivot axis for grounding, eliminating the need for additional contact force devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If axial contact and specific circumference arrangements are used, then contact with shaft is formed, but the device cannot form secure contact regardless of rotation direction and cannot adapt to shafts with varying diameters
Solution Approach 1:
The holder legs are made pivotable relative to each other about a pivot axis, allowing the holder angle to be dynamically adjusted. This enables the contact sections to adapt to different shaft diameters and maintain reliable tangential contact regardless of rotation direction, resolving the contradiction between adaptability and contact reliability.
Solution Approach 2:
The device allows changing the holder angle parameter to adapt to different shaft diameters. By adjusting this geometric parameter, the contact sections can be positioned tangentially to shafts of varying sizes, ensuring secure contact while maintaining versatility across different applications.
2Adaptability or versatility
If carbon fiber arrangement is arranged on an annular holder, then discharging function is provided, but the device is suitable only for shaft with defined circumference
Solution Approach 1:
The holder is segmented into two separate holder legs that can pivot independently. This segmentation allows each leg to be adjusted to accommodate different shaft circumferences, providing versatility without requiring a completely different holder structure for each application.
Solution Approach 2:
The pivotable holder leg design provides multi-functionality, allowing the same holder structure to work with shafts of different circumferences and diameters. This universal design eliminates the need for multiple specialized holders, reducing overall device complexity while increasing adaptability.
3Reliability
If shaft contact sections are arranged tangentially to shaft circumference, then contact is formed irrespective of rotation direction, but adjustment of contact distance and force requires complex mechanisms
Solution Approach 1:
The bending-elastic conductor arrangement provides self-adjusting contact force through its elastic properties. The conductors automatically adapt to maintain tangential contact with the shaft surface, eliminating the need for complex external adjustment mechanisms while ensuring reliable contact regardless of rotation direction.
Solution Approach 2:
By adjusting the holder angle parameter, both the contact distance and contact force can be controlled simultaneously. This single parameter adjustment simplifies the mechanism while achieving the desired tangential contact consistency across different operating conditions.

AI summary
A discharging device for discharging electrostatic charges from a shaft includes a conductor arrangement having at least two bending elastic conductors arranged on a holder and made of a carbon-fiber arrangement. The holder has two holder legs arranged on a common pivot axis, each holder leg serving to accommodate a terminal section of a conductor. The holder legs are pivotable relative to each other to enable a holder angle (α) formed between the holder legs to be adjusted. The holder legs are lockable in a defined pivoted position.
