Packaging Container Snap-Fixation for Scratch-Free Stacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging containers for multimedia storage carriers, such as CDs and DVDs, are inconvenient for inserting and removing due to reliance on central supports, which can damage the carriers, and stacking these containers can lead to scratching and data loss.
Innovation Solution
A packaging container design featuring snap portions and snap groove portions with elastic movable members that allow for quick fixation and release of multimedia storage carriers without central supports, enabling smoother handling and preventing scratches during stacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a central support is used to fix the multimedia storage carrier, then the carrier is securely held in the container, but it becomes inconvenient to insert or remove the carrier and may cause damage to the carrier
Solution Approach 1:
The patent divides the fixation function into multiple independent snap portions distributed around the periphery of the container, replacing the single central support structure. Each snap portion independently secures the carrier at different locations, achieving stable fixation without requiring a central support that interferes with carrier insertion and removal.
Solution Approach 2:
The patent removes the central support structure from the container design entirely. By extracting this problematic element and replacing it with peripheral snap portions, the design eliminates the interference with carrier handling while maintaining secure fixation through distributed attachment points around the carrier's perimeter.
2Stability of the object's composition
If the multimedia storage carrier is fixed by pressing against the central support, then the carrier is secured, but it requires two hands to operate and is very inconvenient for large-sized carriers
Solution Approach 1:
The patent removes the central support structure that requires manual pressing operations. By replacing it with snap portions that automatically engage with the carrier's peripheral features, the design eliminates the need for complex two-handed operations while maintaining secure carrier securing.
Solution Approach 2:
The snap portions are designed to automatically engage with corresponding features on the carrier when it is placed in the container. This self-servicing mechanism eliminates the need for manual pressing or complex operational steps, allowing single-handed or even passive insertion while maintaining secure fixation.
3Quantity of substance
If protective trays are stacked to store multimedia storage carriers, then space is efficiently utilized, but the trays may scratch the carriers during movement causing data loss
Solution Approach 1:
The patent employs a flexible or soft inner lining or film within the container that contacts the carrier surface. This flexible layer acts as a protective barrier during stacking and movement, preventing direct hard-surface contact that causes scratching while allowing the containers to be stacked efficiently for space optimization.
Solution Approach 2:
The container design incorporates protective elements in advance that cushion the carrier from potential damage during stacking operations. By providing this protective layer before any damage can occur, the design prevents scratching issues that would otherwise arise from tray movement and contact during storage and handling.
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
Facilitates easier and safer handling of multimedia storage carriers by eliminating the need for central supports and providing a stable stacking mechanism that prevents scratching, enhancing usability and data protection.
Implementation Method 1
The movable member is an elastic member which is configured to apply force to the multimedia storage carrier, to drive the multimedia storage carrier to move out from the snap groove cavity.

AI summary
A packaging container for a multimedia storage carrier includes a panel portion and a peripheral side portion. The panel portion is arranged in the peripheral side portion in a sunken manner, and an inner cavity for accommodating the multimedia storage carrier is defined by the panel portion and an inner wall of the peripheral side portion. An inner edge of the peripheral side portion is provided with a snap portion and a snap groove portion opposite to the snap portion. The snap portion and the snap groove portion are configured to fix the multimedia storage carrier in the inner cavity. The snap portion is provided with a support member that abuts against a bottom surface of the multimedia storage carrier, and the support member is configured to support the multimedia storage carrier.
