Folding Protective Cover with Elastic Bands for Stand
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective covers for electronic devices are bulky, prone to component failure, and require multiple parts to function as a stand, necessitating a need for improved and simplified designs that are both protective and aesthetically appealing.
Innovation Solution
A protective cover design featuring a front and rear cover with a folding portion, an articulable back, an elastic holding sheet with corner bands for secure attachment, and anti-slip pads, allowing for a low-profile, durable, and versatile solution that reduces component complexity and thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional protective covers use multiple parts and components to provide protection and stand functionality, then the protective capability and functionality are improved, but the profile thickness and device complexity increase
Solution Approach 1:
The patent combines multiple functions into a single integrated cover structure. The cover integrates protection, device attachment via elastic bands, and stand functionality with adjustable angles into one piece, eliminating the need for separate components and reducing overall complexity while maintaining all essential functions
Solution Approach 2:
The cover is designed to perform multiple functions simultaneously: it provides protective coverage, secures the device using elastic bands, and serves as an adjustable stand. This multi-functionality reduces the need for additional separate components, addressing the contradiction between comprehensive functionality and component count
2Ease of operation
If conventional protective covers use plastic clips or holders to attach the electronic device, then the device attachment function is provided, but the reliability decreases over time due to component breakage
Solution Approach 1:
The patent replaces durable but complex mechanical clips with simple elastic bands that can be easily replaced if needed. The elastic bands provide reliable attachment through continuous tension without moving parts that can break, and their simple construction makes them more reliable over time compared to plastic clips with hinges and springs
Solution Approach 2:
The patent replaces the mechanical clip system with an elastic band system that uses elasticity rather than mechanical interlocking. This substitution eliminates complex mechanical joints and fasteners that are prone to failure, providing more reliable attachment through simple elastic tension
3Adaptability or versatility
If conventional protective covers use additional components like legs to function as a stand, then the stand functionality is achieved, but the profile thickness and bulk increase
Solution Approach 1:
The patent implements a dynamic stand system where the back cover can be folded to various angles relative to the main body. This flexible, adjustable design provides multiple stand positions without requiring fixed extended legs, maintaining a low profile when not in use while offering full stand functionality when needed
Solution Approach 2:
The stand functionality is achieved by utilizing the folding dimension of the back cover rather than extending thickness through separate legs. The cover transitions from a flat protective layer to a three-dimensional support structure by folding along the hinge axis, providing stand capability without increasing the cover's thickness dimension
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design provides enhanced protection, durability, and versatility by minimizing bulk, reducing component count, and enabling multiple stand angles without obstructing the screen or device functionality, while being easy to replace and cost-effective.
Implementation Method 1
an elastic flat holding mat that is attached to an inner surface of the exterior section of the rear cover sheet, the holding mat having openings located at corners of the holding mat, the openings configured to be pulled over corners of the electronic device so that the opening engage with corners of the electronic device for securing the electronic device to the casing
Implementation Method 2
an anti-slip pad attached to an inner surface of the front cover
Implementation Method 3
a folding portion that connects the middle rear cover to the exterior rear cover... an articulable back that connects the rear cover to the front cover
