Electronic Device Cover Asymmetric Convex-Concave Fitting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic device covers, such as storage cases for portable game machines, fail to provide a secure and easy attachment/detachment mechanism that prevents removal during use or transport.
Innovation Solution
The electronic device cover features distinct convex and concave portions with different insertion directions, allowing for stable fixation and easy attachment/detachment, utilizing flexible materials and a combination of cover portions to securely hold the device while allowing for continued functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional storage case is used to protect the electronic device, then the device is protected from damage, but the attachment and detachment process becomes complex and time-consuming
Solution Approach 1:
The cover is divided into a first cover portion and a second cover portion that can be attached and detached separately from the electronic device. Each cover portion has its own convex-concave fitting mechanism, allowing independent attachment and detachment operations that are simpler and faster than conventional single-piece storage cases
Solution Approach 2:
The first cover portion and second cover portion are nested together to form a complete protective cover when both are attached to the electronic device. The convex portions of one cover portion fit into concave portions of the other, creating a compact nested structure that provides comprehensive protection while maintaining ease of operation
2Ease of operation
If the cover is made easily detachable, then the operation is simple, but the cover may be accidentally removed during use or transport
Solution Approach 1:
The convex portions and concave portions are designed with asymmetric geometries that provide directional fitting. The convex portions have specific shapes that match corresponding concave portions, creating a secure fit that requires deliberate action to detach while preventing accidental removal during normal use or transport
Solution Approach 2:
The convex and concave portions utilize curved surfaces that provide smooth insertion and secure engagement. The curved geometries allow for easy attachment by simple insertion while maintaining stable fixation once attached, balancing ease of operation with reliable attachment
3Reliability
If multiple convex and concave portions are used for stable fixation, then the attachment stability is improved, but the device complexity increases
Solution Approach 1:
The cover structure is segmented into two main portions with multiple convex-concave fitting points distributed across them. This segmentation allows for stable fixation through multiple contact points while keeping each individual cover portion relatively simple in design, avoiding the need for a single complex integrated structure

AI summary
An electronic device cover includes a first cover portion configured to cover at least a part of an electronic device, the first cover portion being attachable to and detachable from the electronic device. The first cover portion includes a first convex portion configured to fit into a first concave portion provided in the electronic device and a second convex portion configured to fit into a second concave portion provided in the electronic device. When attaching the electronic device cover to the electronic device, a first insertion direction in which the first convex portion is inserted into the first concave portion and a second insertion direction in which the second convex portion is inserted into the second concave portion are different.
