Electronic Packing Structure Using Cross-Rib Support to Prevent Bag Tearing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packing structures for electronic devices, such as those described in JP-A-2012-246038, face issues where the accommodation bag is prone to tearing due to the ribs of the shock absorbing member being pressed against the cores during transportation, leading to potential damage.
Innovation Solution
The electronic device incorporates ribs on its outer surface that intersect the direction of the cores of the shock absorbing member, increasing the contact area and reducing the likelihood of tearing by ensuring the ribs extend at a 45-degree angle to the core direction, with multiple ribs and coupling portions to enhance stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the rib is pressed against the core of the shock absorbing member, then the strength of the bottom surface is ensured, but the accommodation bag may be torn due to shaking during transportation
Solution Approach 1:
The rib is configured to extend in a direction intersecting the first direction in which the core extends. This dimensional change in orientation increases the contact area between the rib and core from a line contact to a surface contact, distributing the pressure and preventing the accommodation bag from tearing while maintaining the strength of the bottom surface.
2Device complexity
If the rib extends parallel to the core, then the contact area is minimized, but the accommodation bag is more prone to tearing during transportation
Solution Approach 1:
Instead of extending the rib parallel to the core (one-dimensional alignment), the rib is configured to intersect the core direction at an angle. This introduces a dimensional component that increases the contact area, thereby protecting the accommodation bag from tearing while maintaining structural simplicity.
3Strength
If multiple ribs are formed to ensure strength, then the strength of the device main body is improved, but the accommodation bag is more likely to be torn due to increased pressure on cores
Solution Approach 1:
By configuring the rib to extend in a direction intersecting the core direction, the contact area between the rib and core is increased. This dimensional orientation change allows multiple ribs to be formed without concentrating pressure on the accommodation bag, as the intersecting angle distributes the force across a larger contact surface area.

AI summary
A packing structure is a packing structure including an electronic device including a device main body, an accommodation bag accommodating the device main body, a shock absorbing member coming into contact with ribs formed at a bottom surface of the device main body via the accommodation bag, and a packing box accommodating the device main body via the accommodation bag and the shock absorbing member, in which the shock absorbing member is corrugated cardboard having cores extending in parallel with one side of a bottom surface of the packing box, and the ribs extend in a direction intersecting a first direction in which the cores extend.
