Protection Cover Attachment Structure for Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protection covers for electronic devices, such as notebook computers, fail to provide sufficient protection against impacts and drops due to loose fittings and unstable orientations, leading to potential damage and increased risk of accidental drops.
Innovation Solution
A protection cover design featuring a main body portion with a flexible inner face and stiff outer face, incorporating protrusion members and holes with specific diameter relationships to securely attach to the device's housings, ensuring stable positioning and reduced looseness during use and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a case body is attached to the portable information terminal device only at the vicinity of an end portion using a hook-and-loop fastener, then the attachment process is simple, but a part not covered by the case body increases when the device is grasped by a hand, preventing sufficient protection against disturbances such as impact
Solution Approach 1:
The protection cover is divided into multiple attachment regions: a first attachment region at one end portion and a second attachment region at another end portion. This segmentation allows the cover to be securely fixed at both ends, preventing the cover from shifting or exposing unprotected areas when the device is grasped, while maintaining simple hook-and-loop fastener attachment throughout.
2Area of stationary object
If a cover is fixed to a main body portion and a display portion, then the cover provides comprehensive coverage, but the cover loosens significantly in a part between the main body portion and the display portion when the information processor is open, making the orientation unstable and increasing the possibility of dropping
Solution Approach 1:
The attachment structure is segmented into multiple regions: a first attachment region connecting the protection cover to the main body portion, and a second attachment region connecting the protection cover to the display portion. This segmentation at both ends maintains comprehensive coverage while preventing loosening in the middle section when the device is opened or closed.
Solution Approach 2:
The protection cover integrates both the main body cover and display cover into a single unified structure that attaches at both ends simultaneously. This merging ensures that the cover maintains its position and tightness across the entire device surface, preventing the loosening that occurs with separate cover components.
3Stability of the object's composition
If the cover is securely fixed to prevent loosening, then the orientation stability is maintained, but the attachment structure becomes more complex
Solution Approach 1:
The hook-and-loop fastener system serves multiple functions: it provides secure attachment at both ends of the device, maintains cover tension across the entire surface, and allows for easy attachment and detachment. This universal attachment mechanism achieves orientation stability without requiring complex mechanical fastening structures.

AI summary
A first coupling member 20 can be engaged with a first engagement hole 2e and held slidably by a first support member 12. A second coupling member 30 of the present embodiment can be engaged with a second engagement hole 2f and held slidably by a second support member 13. With this configuration, a relative position between a second housing 2 and a protection cover 10 changes at the time of turning the second housing 2 in a direction indicated by an arrow A or B, which can prevent the protection cover 10 from loosening significantly near the hinge portions 3.
