Dovetail Bracket Mounting With Magnetic Tool-Free Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building systems lack an efficient and easy method for attaching and detaching building components from profiles without requiring tools, and existing magnetic solutions are not magnetically releasable once locked.
Innovation Solution
A building system with a profile having a dovetailed opening and a bracket featuring a bi-stable plate spring that can be biased against the profile's side walls for secure attachment and detachment, utilizing a magnet-sensitive tongue for tool-free release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a bi-stable plate spring is used to provide strong locking force, then the bracket is securely locked in the profile, but the bracket cannot be easily released
Solution Approach 1:
The patent replaces the purely mechanical bi-stable spring system with a magnetically controllable system. A magnet is integrated into the bracket, and a magnetically attractable material is placed in the profile, allowing the spring to be held in either stable position (locked or unlocked) through magnetic attraction rather than requiring manual manipulation of the spring mechanism itself.
Solution Approach 2:
The patent introduces a magnetically attractable material as an intermediary between the magnet in the bracket and the bi-stable spring mechanism. This intermediary allows magnetic force to control the spring's position, enabling easy release by simply removing the magnetic attraction rather than manually manipulating the spring.
2Stability of the object's composition
If a dovetailed profile opening is used to prevent bracket displacement, then the bracket is securely retained, but the installation process becomes more complex
Solution Approach 1:
The patent makes the retention system dynamic by using a bi-stable spring that can transition between two stable positions. The spring naturally biases the bracket against the profile walls for secure retention, but can be easily moved to an unlocked position through magnetic control, allowing the system to adapt between secure retention and easy removal states.
3Strength
If the side engagement members are biased against the side walls, then the bracket is securely mounted, but the insertion process requires more force
Solution Approach 1:
The patent uses preliminary magnetic attraction to hold the bracket in the unlocked position during insertion. The magnet attracts the magnetically attractable material in the profile, keeping the bi-stable spring in its first stable position (unlocked) throughout the insertion process, eliminating the need to force the spring against the profile walls during installation.
