Wiper Arm Fluid Pipe Clip with Elastic Snap Mount
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for attaching fluid circulation pipes to wiper arm drive arms are cumbersome, requiring specific tools and being aesthetically unappealing due to their size and visibility.
Innovation Solution
A fixing staple with elastic latching means and anti-rotation features, allowing for easy mounting and dismounting by engaging with the arm's orifice, featuring elastically deformable tabs and anti-rotation fingers to secure the pipe without visible fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If elastic snap fastening means are used to attach the staple to the drive arm, then the mounting method becomes simpler and does not require specific tools, but the staple becomes relatively large in size
Solution Approach 1:
The staple is divided into functionally independent parts: fixing means with elastic latching tabs for attachment to the drive arm, and retaining means with a through slot for pipe retention. This segmentation allows each part to be optimized independently - the fixing means can use simple elastic snap for easy manual installation, while the retaining means provides the necessary pipe holding function, resolving the contradiction between ease of mounting and compact size.
2Volume of moving object
If the fixing means and retaining means are located on the same side of the staple, then the structure becomes more compact, but it becomes difficult to manipulate both means independently during mounting
Solution Approach 1:
The staple is divided into functionally independent parts: fixing means with elastic latching tabs for attachment to the drive arm, and retaining means with a through slot for pipe retention. This segmentation allows each part to be optimized independently - the fixing means can use simple elastic snap for easy manual installation, while the retaining means provides the necessary pipe holding function, resolving the contradiction between ease of mounting and compact size.
Solution Approach 2:
The fixing means and retaining means are positioned on opposite sides of the staple body, utilizing spatial distribution in different directions. This dimensional arrangement allows operators to access and manipulate each means independently from opposite sides, avoiding interference during installation while maintaining overall structural compactness.
3Ease of manufacture
If visible fasteners are used to attach the pipe to the arm, then the attachment method becomes simpler, but the aesthetic appearance deteriorates due to visibility
Solution Approach 1:
The staple is designed to be received within a recess or cavity in the drive arm structure, with the elastic latching means engaging from the interior. This nesting arrangement hides the fastening mechanism from external view, maintaining aesthetic appearance while preserving the simplicity of the elastic snap attachment method for manufacturing and installation.
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
Facilitates simple and efficient attachment of fluid circulation pipes to wiper arm drive arms, reducing the need for tools and ensuring the pipes are not visible, while preventing rotation and providing secure retention.
Implementation Method 1
the fastening means are of a particular type because they comprise elastic latching means which are configured to be engaged in an orifice of the arm, and pass through this orifice
Implementation Method 2
the anti-rotation means comprise at least one finger having a support surface
