Rotating Fastening Bracket for Quick Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for fastening add-on parts to support parts are time-consuming due to the need for multiple screw turns, which prolongs the fastening operation.
Innovation Solution
A rotatable fastening bracket with bracket arms that can be positioned 90 degrees to establish or release the connection between the add-on and support parts, allowing for efficient engagement and disengagement by rotating between a locking and releasing position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw is used to tighten the fastening bracket, then the connection between the add-on part and support part is secure, but the fastening operation becomes time-consuming due to multiple turns required
Solution Approach 1:
The fastening bracket is designed to be rotatable within the receiving space, transforming the static screw-fastening mechanism into a dynamic rotational one. This allows the bracket arms to move between engaged and disengaged positions, enabling quick connection and disconnection without time-consuming screw turns while maintaining secure connection when engaged
2Strength
If the bracket arms are positioned to engage behind the support part, then the pull-out strength is increased, but the disconnection process becomes complex
Solution Approach 1:
The rotatable fastening bracket enables the bracket arms to dynamically transition between an engaged position (providing high pull-out strength when bracing against the support part) and a disengaged position (allowing easy removal). This rotational movement simplifies disconnection by eliminating the need to undo multiple screw turns while maintaining strong engagement when connected

AI summary
A device for fastening an add-on part to a support part is equipped with a fastening bracket, which has a flat cover plate and, at opposite sides, bracket arms which are attached to the cover plate, and with a bearing part which can be connected to the fastening bracket. The bearing part has a receiving space in which the cover plate of the fastening bracket is mounted so as to be rotatable between a locking position, in which the bracket arms engage behind the support part, and a release position in which the bracket arms are not in engagement with the support part. In this way, an add-on part can be connected to and disconnected again from a support part in an efficient and reliable manner.
