Awning Fastening System Anti-Loosening Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing awning attachment systems for camping vehicles are uncomfortable to use and expensive to manufacture, and they lack reliable mechanisms to prevent screws from loosening unintentionally due to vibrations.
Innovation Solution
An awning attachment system featuring a first bracket with first fastening means and a second bracket with a stop surface that runs perpendicularly to the screw axis, preventing loosening by blocking movement in the loosening direction, and a third mount compatible with various awning housings, allowing for secure attachment without gluing or drilling into the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional means are provided for securing the first fastening means against unintentional loosening, then reliability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines the fastening function and the anti-loosening function into a single integrated bracket assembly. The second bracket serves dual purposes: it fastens the awning housing while simultaneously providing the stop surface that prevents loosening of the first fastening means. This eliminates the need for separate anti-loosening devices while maintaining security against unintentional loosening.
Solution Approach 2:
The second bracket is designed to automatically provide the stop surface that prevents loosening of the first fastening means. The system uses its own structural elements (the second bracket with integrated stop surface) to secure itself against loosening, rather than requiring external anti-loosening mechanisms. The stop surface is formed as part of the bracket's own structure, making it self-sufficient.
