Magnetic Hook Protection Cover for Slim Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protection covers for electronic devices increase weight and thickness due to holding and fixing units, affecting the slimness and grip of the device, and require complex assembly processes.
Innovation Solution
The use of hook units and attaching/detaching units that latch and release the protection cover from the electronic device using magnetic forces or integrated attachment locking units, eliminating the need for conventional holding and fixing units, thereby reducing weight and thickness and simplifying assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional holding portion and fixing units are used to attach the protection cover to the electronic device, then the attachment reliability is improved, but the weight and thickness of the protection cover increase
Solution Approach 1:
The patent extracts and eliminates the conventional holding portion and fixing units from the protection cover structure. Instead, it uses hook units that are integrally formed with the rear cover, thereby removing unnecessary components that add weight while maintaining attachment functionality through magnetic attraction between the hook units and the electronic device.
Solution Approach 2:
The patent merges the hook units directly into the rear cover through integral formation, combining the attachment mechanism with the cover structure itself. This eliminates separate holding portions and fixing units, reducing overall weight while maintaining secure attachment through the combined structural integrity of the integrated hook units.
2Reliability
If conventional holding portion and fixing units are used to attach the protection cover to the electronic device, then the attachment reliability is improved, but the thickness of the protection cover increases
Solution Approach 1:
The patent removes the conventional holding portion and fixing units that contribute to increased thickness. The hook units are integrally formed with the rear cover in a manner that minimizes thickness addition, allowing the protection cover to maintain a slim profile while achieving reliable attachment through magnetic interaction.
Solution Approach 2:
By merging the attachment function directly into the rear cover through integral hook units, the patent eliminates the need for separate thick holding portions. The combined structure achieves both attachment reliability and thinness by integrating the attachment mechanism within the cover's existing thickness rather than adding separate components.
3Reliability
If conventional holding portion and fixing units are used, then the attachment functionality is improved, but the number of parts and assembly complexity increase
Solution Approach 1:
The patent extracts and eliminates multiple separate components (holding portion, fixing units) from the attachment mechanism. The hook units are integrally formed with the rear cover, reducing the number of parts that need to be assembled while maintaining effective attachment functionality through the simplified integrated structure.
Solution Approach 2:
The patent merges the attachment mechanism with the rear cover through integral formation of hook units, combining multiple functions into a single structure. This reduces assembly complexity by eliminating the need to assemble separate holding portions and fixing units, while maintaining reliable attachment through the integrated design.
