Electronic Device Cover With Rotatable Magnetic Strap Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device covers that provide protection and angle fixation increase the thickness and weight by requiring separate injection-molded materials, and may cause the device to be dropped during carrying.
Innovation Solution
A strap is attached to the electronic device cover, allowing for angle fixation without additional components, using a rotatable design and magnetic coupling for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a separate injection-molded material is attached to the cover to enable angle fixation, then the stand function is available, but the thickness and weight of the cover increase
Solution Approach 1:
The patent combines the stand function with the existing cover structure by integrating a rotatable strap into the cover assembly. The strap is attached to the cover and can be rotated to different positions, allowing the cover to function as a stand without requiring separate injection-molded materials. This merging of functions resolves the contradiction by achieving adaptability while avoiding increased thickness.
Solution Approach 2:
The cover assembly is designed to perform multiple functions: protection, angle fixation, and carrying. The rotatable strap serves as a multi-functional element that enables both the stand function and secure carrying. By making the cover universal in its capabilities without adding separate components, the patent resolves the contradiction between versatility and thickness.
2Adaptability or versatility
If a separate injection-molded material is attached to the cover to enable angle fixation, then the stand function is available, but the weight of the cover increases
Solution Approach 1:
The patent merges the stand function with the existing cover structure using a rotatable strap that is integrated into the cover assembly. This eliminates the need for separate injection-molded materials, thereby achieving the stand function without increasing the weight of the cover.
Solution Approach 2:
The patent employs a flexible strap structure that can be rotated and positioned to provide stand functionality. This flexible element replaces rigid injection-molded materials, reducing the overall weight while maintaining the required adaptability for angle fixation.
3Reliability
If the cover is designed for secure carrying, then the user may carry the device safely, but the user may drop the device while carrying it
Solution Approach 1:
The patent introduces a rotatable strap that can dynamically adjust to different positions and orientations. This dynamic element allows the user to easily adjust the carrying position and angle, improving ease of operation while maintaining secure attachment through the rotatable connection mechanism.
Solution Approach 2:
The rotatable strap enables changes in the carrying parameters (angle, position, orientation) without compromising the secure attachment. The user can adjust the strap to different angles and positions based on carrying preferences, improving convenience while the magnetic coupling maintains reliable attachment throughout the range of motion.
