Solution Overview
Problem
Existing methods for cleaning the fastening surface of vehicle wheel rims for compensating elements are not reproducible and cannot be integrated into a fully automatic unbalance compensation process, often resulting in variable adhesion due to inconsistent cleaning agent usage.
Innovation Solution
A method and device that utilize a handling device to move a rotatable cleaning device coated with a cleaning agent to the rim, ensuring mechanical and chemical cleaning, allowing for precise control and efficient cleaning of multiple surfaces in a single step, with the cleaning agent evaporating before attachment, ensuring secure fastening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual cleaning with cleaning cloth and cleaning agent is used, then cleaning effect is improved, but reproducibility and automation capability deteriorate
Solution Approach 1:
The patent replaces manual mechanical cleaning with an automated rotating cleaning device that is mechanically driven. The cleaning device rotates against the fastening surface to provide consistent mechanical cleaning action, eliminating variability in manual wiping while maintaining effective cleaning capability.
Solution Approach 2:
The cleaning device is designed to automatically apply and distribute cleaning agent through its rotation, without requiring manual intervention. The system self-regulates the cleaning process through controlled rotation and automated positioning, enabling both effective cleaning and automation.
2Manufacturing precision
If large amount of cleaning agent is used, then cleaning effect is improved, but evaporation completeness and fastener impairment risk worsen
Solution Approach 1:
The cleaning device applies cleaning agent locally and precisely to the fastening surface through controlled rotation and positioning. The cleaning agent is distributed evenly only where needed on the rim's fastening surface, avoiding excessive application that would prevent complete evaporation and potentially harm the fastener.
Solution Approach 2:
The system controls the amount and distribution of cleaning agent by adjusting rotation parameters and positioning. By optimizing the cleaning device's rotation speed and contact pressure, the cleaning agent is applied in precise quantities that ensure effective cleaning while allowing complete evaporation before fastener attachment.
3Manufacturing precision
If multiple fastening surfaces are cleaned separately, then cleaning thoroughness is improved, but processing time and efficiency worsen
Solution Approach 1:
The cleaning device is designed with multi-functionality to clean multiple fastening surfaces on the rim through a single rotating motion. By positioning the device to rotate against the rim's interior surface, it can sequentially clean multiple fastening locations without requiring separate cleaning operations for each surface.
Solution Approach 2:
The cleaning device maintains continuous rotation and contact with the rim surface to clean multiple fastening surfaces in sequence without interruption. This continuous action eliminates the need to stop and reposition between surfaces, maintaining thorough cleaning while significantly improving processing efficiency.
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
The solution provides reproducible and efficient cleaning of the fastening surfaces, ensuring secure attachment of compensating elements by automating the process, reducing cleaning agent usage, and preventing impairment of the fastener, enabling integration into an assembly line for permanent and secure fastening.
Implementation Method 1
the cleaning device is set in rotation about its axis by a motor and rotatably cleans at least one fastening surface on the inside of the rim
Implementation Method 2
a small amount of cleaning agent is used for cleaning, so that it is also ensured that the cleaning agent essentially completely evaporates by the time the compensating element is attached
