Sliding Corner Protection for Fragile Object Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers, such as those described in Patent Document No. 1, often cause breakage or cracking of accommodated objects like display panels or glass/plastic plates during removal or transportation due to the corner protection members rotating under acceleration, leading to inefficiencies in handling and increased damage risks.
Innovation Solution
A container design featuring protection members with inner and outer components that are slidable and detachable, where the inner member is more easily warped than the outer, and the outer member is made of expanded plastic, providing enhanced support and impact absorption to prevent rotation and damage during acceleration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a corner protection member is provided at the corner of the accommodation space, then the corner of the accommodated object is protected from breakage, but the corner protection member may rotate during transportation when large acceleration is applied, causing the accommodated object to be cracked or chipped
Solution Approach 1:
The corner protection member is divided into an inner member and an outer member that can move independently relative to each other. The inner member has a receiving portion with receiving surfaces for contacting the corner of the accommodated object, while the outer member surrounds the inner member. This segmentation allows the inner member to rotate independently to absorb acceleration forces without transmitting them to the accommodated object, while the outer member provides structural support and guidance.
Solution Approach 2:
The corner protection member transitions from a static structure to a dynamic one where the inner member can rotate within the outer member. This dynamic capability allows the protection member to adapt to acceleration forces during transportation by rotating to absorb the force, preventing the force from being transmitted to the corner of the accommodated object.
2Reliability
If a corner protection member is provided at the corner of the accommodation space, then the corner of the accommodated object is protected from breakage, but the corner protection member may stick to the corner of the display panel during removal, decreasing work efficiency and preventing automated removal

3Reliability
If a corner protection member is provided at the corner of the accommodation space, then the corner of the accommodated object is protected from breakage, but the container structure becomes more complex
Solution Approach 1:
The inner member is nested within the outer member, with the inner member's receiving portion positioned inside the outer member's cavity. The outer member acts as a housing that guides and constrains the movement of the inner member. This nesting arrangement provides a compact structure where the complex functionality of two movable parts is achieved within a space-efficient configuration.
Solution Approach 2:
The corner protection member transitions from a static structure to a dynamic one where the inner member can rotate within the outer member. This dynamic capability allows the protection member to adapt to acceleration forces during transportation by rotating to absorb the force, preventing the force from being transmitted to the corner of the accommodated object.
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 container effectively suppresses breakage and efficiency decreases during object removal and prevents corner cracking or chipping during transportation, allowing for safer handling and automated removal of fragile objects.
Implementation Method 1
the outer member is made of expanded plastic, providing enhanced support and impact absorption to prevent rotation and damage during acceleration
Implementation Method 2
A portion, of the inner member, that includes the first receiving surface is more easily warped than a portion, of the inner member, that includes the second receiving surface

AI summary
A container (100) having: a housing member (10) having a bottom surface member (12) and a side surface member (14); and a protective member (220a) having a receiving surface in contact with an item to be housed. The bottom surface member defines the xy plane and the side surface member defines the xz plane and the yz plane that are orthogonal to the xy plane. The side surface member has a cut-out section (15a) that faces a housing space. The protective member (220a) has: an inside member (122a) comprising a receiving section having first receiving surface (123) parallel to the yz plane and a second receiving surface (124) parallel to the xz plane; and an outside member (232a) arranged at least between the inside member and a side surface parallel to the yz plane of the side surface member, said outside member being fitted to the inside member (122a) so as to be slidable in a direction intersecting the floor surface. The inside member (122a) and the outside member (232a) are arranged in the cut-out section so as to each be independently attachable and detachable. A section including the first receiving surface (123) is more flexible than a section including the second receiving surface (124).
