Dome-Shaped Support Cover for Screw Load Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screw connections in components, particularly in vehicles, face challenges with mechanical loads and material buildup due to constant changes in load directions, leading to peak stresses and inefficient reinforcement rib arrangements.
Innovation Solution
A component design featuring a cone-, funnel-, or tent-shaped support cover that replaces traditional reinforcement ribs, providing a stable recess for securing elements like screws, allowing for varied height and thickness adjustments based on load directions, thereby improving stress distribution and reducing material buildup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional reinforcement ribs are used to strengthen screw connections, then mechanical load capacity is improved, but material buildup increases and weight increases
Solution Approach 1:
The patent applies curvature by transitioning from flat reinforcement ribs to a three-dimensional dome-shaped reinforcement structure. This curved geometry distributes mechanical loads more effectively across the screw connection area, providing enhanced strength while using less material compared to traditional flat rib arrangements.
Solution Approach 2:
The invention moves from two-dimensional flat reinforcement ribs to a three-dimensional dome-shaped structure. This dimensional transition allows the reinforcement to absorb and divert mechanical loads from multiple directions simultaneously, improving load capacity while reducing the overall material volume required.
2Reliability
If reinforcement ribs are arranged to handle constant load direction changes, then reliability is improved, but device complexity increases
Solution Approach 1:
The dome-shaped reinforcement structure serves multiple functions simultaneously: it reinforces the screw connection area, absorbs loads from varying directions, and provides structural support. This single multi-functional element replaces what would otherwise require multiple separately arranged reinforcement ribs for different load directions.
Solution Approach 2:
The invention merges multiple reinforcement functions into a single integrated dome-shaped structure. Instead of having separate reinforcement ribs for different load directions, the curved dome geometry combines all reinforcement needs into one unified element that handles loads from any direction.
3Strength
If more material is added to reinforce screw connections, then strength is improved, but manufacturing precision requirements increase
Solution Approach 1:
The invention changes the geometric parameters of the reinforcement structure by using a dome shape with optimized curvature radius and height. This parameter optimization allows the reinforcement to achieve maximum strength with minimal material, and the smooth curved surfaces are more amenable to precise manufacturing processes like die-casting compared to sharp-angled rib structures.

AI summary
A component with a support, for which a flat region is defined. The support has a support cover which at least partly has the shape of a cone, a funnel, or a tent and which is raised out of the flat region. One end of the at least partly cone-, funnel-, or tent-shaped support cover, said end facing away from the flat region of the support, is equipped with a recess for mounting a securing element to be secured to the component.
