Removable Protective Lip on Wiping Element for Contamination Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems with movable components, such as hydraulic systems, face contamination issues during transport and assembly, leading to potential damage and impaired functionality due to foreign particles, especially paint particles, which can enter and cause scoring on components.
Innovation Solution
A wiping element with a detachable protective lip made of rubber or viscoplastic material, featuring a detachment aid for easy removal, which is designed to be attached via a material connection or positive fit, ensuring protection during transport and assembly while allowing for simple detachment post-use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective lip is permanently attached to the wiping element, then the component is continuously protected from contamination, but the protective device cannot be removed after use
Solution Approach 1:
The protective device is divided into two separable parts: the wiping element and the protective lip. The protective lip can be attached to the wiping element when protection is needed, and removed when no longer required. This segmentation allows the system to provide reliable protection when needed while enabling easy removal after use, resolving the contradiction between continuous protection and removability.
2Strength
If a protective lip is made from harder material, then it can scrape off strongly adhering particles, but it may damage the component surface
Solution Approach 1:
The protective lip is designed with non-uniform thickness, creating different local qualities along its structure. The thicker regions provide enhanced scraping capability for strongly adhering particles, while thinner regions reduce the risk of surface damage. This local variation in material distribution allows the protective lip to effectively remove contaminants without causing harmful damage to the component surface.
3Ease of operation
If the protective lip is detachably connected, then it can be removed after use, but the connection must be strong enough to provide reliable protection during use
Solution Approach 1:
The protective lip is pre-assembled with the wiping element as a ready-to-install unit before use. The detachable connection is designed to be automatically engaged during installation, providing reliable protection immediately without requiring separate attachment steps. This preliminary preparation ensures both strong connection during use and easy removal when needed, resolving the contradiction between connection reliability and removal capability.

AI summary
The invention relates to a wiping element (1) which is made of a rubber-elastic or viscoelastic material and is used for protecting parts that are moved towards each other, at least one wiping lip (2) being provided on the wiping element (1). The wiping element (1) is fitted with a protective lip (4) which is or can be removably attached to the wiping element (1). The wiping element (1) is disposed in a stable position on a first part of a wiping arrangement (10) while resting against a second part by means of the wiping lip (2) and the protective lip (4). When such a wiping arrangement (10) is used for lacquering parts that can be moved towards each other, at least one part is lacquered in the attached state of the protective lip (4), whereupon the protective lip (4) is removed from the wiping element (1).
