Segmented Rack Post Assembly for Repositionable Middle Shelves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assembly shelves require the removal of upper shelf board members to change the position of a middle shelf board member, causing inconvenience during multi-stage assembly.
Innovation Solution
An assembly shelf design featuring a post with two main sections and connection members that allow for the independent removal and reinstallation of a middle shelf board member without disturbing other board members, utilizing through-holes and engagement elevations/depressions for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single post is used to connect shelf board members in a multi-stage assembly, then assembly is simplified and design is improved, but the middle shelf board member cannot be removed or repositioned without removing the upper shelf board members
Solution Approach 1:
The connection between the shelf board member and post is segmented into two independent connection members: a first connection member that connects to the post, and a second connection member that connects to the shelf board member. This segmentation allows the second connection member to be independently removed from the post while leaving the first connection member attached, enabling middle shelf board removal without disturbing upper shelf board members.
Solution Approach 2:
The second connection member is extracted as a separate, removable component from the post-shelf board connection system. This extracted component can be selectively removed from the post to allow middle shelf board member removal or repositioning, while the first connection member remains attached to maintain the overall structure and support upper shelf board members.
2Adaptability or versatility
If upper shelf board members are removed to change the position of a middle shelf board member, then the middle shelf board can be repositioned, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The connection system is segmented into two independent connection members, allowing selective removal of only the second connection member when middle shelf board repositioning is needed. This eliminates the need to remove upper shelf board members, significantly reducing the time and effort required for shelf board position changes.
Solution Approach 2:
The connection members are designed to be dynamically configurable - the second connection member can be easily attached to or removed from the post depending on whether middle shelf board repositioning is needed, while the first connection member remains fixed to maintain structural integrity. This dynamic configuration enables quick adaptation without time-consuming disassembly of the entire shelf structure.

AI summary
An assembly shelf includes a post that includes two main post sections and a connection section that connects the main post sections a plurality of through-holes being formed in the connection section along a longitudinal direction, a pair of connection members, each of the pair of connection members including a first engagement section that engages the post, and a second engagement section that engages a shelf board member, and a shelf board member that includes a third engagement section that is formed approximately at each corner and engages the second engagement section, the pair of connection members and the shelf board member being positioned within the range that corresponds to half of the post in the lateral direction.
