Mounting Structure for Irregular Contour Openings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for mounting parts into openings with irregular contours result in imprecise centering and unreliable assembly due to machining errors, particularly in milling processes, leading to potential assembly risks and reduced quality.
Innovation Solution
A parts mounting structure featuring a retaining element with a head and rod, incorporating an elastic clip with hooking claws that engage with offset ribs inside the opening, ensuring precise centering and secure attachment, even in irregularly shaped openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If openings are made by machining (milling), then the opening can be created in the base part, but the outline becomes imprecise and centering is only approximate
Solution Approach 1:
The patent introduces an intermediary centering element that mediates between the imprecise machined opening and the part requiring precise centering. This element provides reference surfaces that enable accurate positioning without requiring the opening itself to be precisely machined.
Solution Approach 2:
The invention creates a copy or replica of the precise geometric features needed for centering, embedded within the retaining element. Rather than requiring the opening to have precise geometry, the precise features are copied into the retaining element itself, which then transfers this precision to the assembled part.
2Adaptability or versatility
If openings with irregular contours are used, then manufacturing flexibility is improved, but assembly precision and reliability deteriorate
Solution Approach 1:
The patent applies local quality by providing precise centering features only at specific locations within the retaining element, rather than requiring the entire opening to have precise geometry. The irregular contour of the opening is acceptable because precision is localized to the centering surfaces.
Solution Approach 2:
The retaining element is pre-equipped with precise geometric features and centering surfaces before assembly. This preliminary preparation of precision features in the retaining element compensates for the imprecision of the irregular opening, ensuring reliable assembly without requiring the opening to be precisely formed.
