Storage Shelf Support Plate Notch Rigidity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing article storage shelves with notches in the support plate section face issues with reduced rigidity, leading to bending and instability when supporting articles, which can be exacerbated by attempts to reinforce the shelf, resulting in increased size and cost.
Innovation Solution
The design incorporates a through-opening in the support plate section between the third support pin and the attachment section, allowing the section to bend more easily and thereby increasing the rigidity between the first and second support pins, while also allowing airflow to pass through, enhancing stability and preventing airflow issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a notch is formed in the support plate section to allow transfer device passage, then the transfer device can access the article, but the rigidity of the support plate section decreases causing bending and instability
Solution Approach 1:
The patent applies local quality by creating a through-opening at a specific location (between the third support pin and attachment section) with specific dimensional characteristics (larger dimension in second direction than first direction). This localized structural modification allows the transfer device to pass through while preserving the overall rigidity of the support plate section by strategically positioning the opening away from critical support areas.
2Strength
If reinforcing members are attached to increase rigidity of the support plate section, then bending is reduced and stability is improved, but the size and weight of the shelf body increase
Solution Approach 1:
The patent extracts the unnecessary reinforcement by realizing that a strategically positioned through-opening can provide the required access while the natural structure of the support plate section (with the opening positioned between the third support pin and attachment section) inherently maintains sufficient rigidity. This eliminates the need for additional reinforcing members, thereby reducing size and weight while maintaining stability.
3Stability of the object's composition
If the support plate section is made more rigid to prevent bending, then support stability is improved, but the ability to allow airflow through the shelf body is reduced
Solution Approach 1:
The patent applies local quality by creating a through-opening with specific dimensional characteristics (larger dimension in the second direction than in the first direction) at a strategically positioned location. This localized modification allows airflow to pass through the shelf body while the opening's position and dimensions are controlled to maintain the overall structural stability and flatness of the support plate section.

AI summary
An article storage shelf includes a shelf frame; a shelf body configured to support an article as a storage target; and a transfer device. The transfer device includes a support section configured to support the article, and a drive mechanism. The shelf body includes an attachment section attached to the shelf frame, and a support plate section projecting toward a first-direction first side from the attachment section. The support plate section has a notch penetrating through the support plate section in the up-down direction and opened toward the first-direction first side, and a through-opening disposed on a first-direction second side relative to the notch and penetrating through the support plate section in the up-down direction. The through-opening is disposed between a third support pin and the attachment section in the first direction and has a dimension, in a second direction, that is larger than a dimension in a first direction.
