Foldable Pouch Cradle for Tablet PC with Adjustable Grooves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable accessory devices for tablet PCs support only one direction and angle, potentially interfering with device operation and aesthetics, and require external magnetic connections that can be cumbersome.
Innovation Solution
A foldable pouch cradle with multiple panels and folding lines that allow the device to be supported in various angles without magnetic interference, using adhesive or sewing for closure and cradle grooves for adjustable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a foldable accessory apparatus uses magnetic elements for attachment and detachment, then the device can be easily attached and detached, but the magnetic element may have a harmful influence on operating the tablet PC
Solution Approach 1:
The patent removes the magnetic element from the accessory apparatus and replaces it with adhesive or sewing-based attachment methods. This extracts the harmful magnetic component while maintaining the attachment function, thereby eliminating interference with the tablet PC's operation while preserving ease of attachment and detachment.
2Reliability
If a foldable accessory apparatus uses a separate connection device protruding to the outside, then the device can be securely attached, but it may disfigure an external appearance design of the tablet PC and increase a weight thereof
Solution Approach 1:
The patent merges the connection device with the body of the accessory apparatus, making it flush-mounted or integrated into the structure. This eliminates protruding elements that would disfigure the tablet PC's appearance while maintaining secure attachment through the folded structure's mechanical engagement.
Solution Approach 2:
The patent uses a flexible folded structure that can be attached to the tablet PC without rigid protruding connection devices. The flexible nature allows for a sleek, low-profile attachment that preserves the tablet's appearance while providing secure attachment through the folded configuration.
3Device complexity
If a foldable accessory apparatus is fixed to support the tablet PC in only one direction and one angle, then the structure is simple, but it cannot support the tablet PC in various angles and directions needed for different operations
Solution Approach 1:
The patent divides the accessory apparatus into multiple foldable sections or panels that can be independently positioned. This segmentation allows the structure to be folded into different configurations, enabling support at various angles and directions while maintaining a relatively simple overall structure based on repeated modular units.
Solution Approach 2:
The patent creates a dynamic folded structure that can be adjusted to different positions and angles. The foldable design allows the accessory to transition between multiple stable configurations, providing adaptability for different viewing angles and operational needs while maintaining structural simplicity through repeated folding patterns.
