Assembly Shelf Post Structure for Independent Middle Shelf Removal
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 operations.
Innovation Solution
An assembly shelf design featuring a post with symmetrical main sections and connection members with engagement protrusions or depressions, allowing for the removal and reinstallation of a middle shelf board member without disturbing other board members, using a pair of connection members that engage the post and shelf board members with specific engagement sections.
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 post and shelf board member is segmented into multiple independent engagement sections: a first engagement section connecting the post to connection members, and a second engagement section connecting the shelf board member to the connection members. This segmentation allows the shelf board member to be disconnected from the post independently without affecting upper shelf board members, resolving the contradiction between assembly simplicity and operational flexibility.
Solution Approach 2:
Connection members are introduced as intermediary components between the post and the shelf board member. These connection members include engagement protrusions that fit into engagement holes in the post, and engagement sections that connect to the shelf board member. This intermediary structure enables independent removal and repositioning of the shelf board member while maintaining the overall assembly simplicity, as the connection members serve as detachable mediators in the connection chain.
2Ease of operation
If connection members with engagement protrusions are used to connect the post and shelf board member, then the shelf board member can be independently removed and repositioned, but the device complexity increases
Solution Approach 1:
Multiple functions are merged into the connection members: they provide structural support, enable engagement with the post through protrusions fitting into holes, and connect to the shelf board member through engagement sections. By combining these functions into a single component, the overall device complexity is minimized while still achieving independent removal and repositioning of the shelf board member.
Solution Approach 2:
The connection members are designed with universal applicability: the engagement protrusions can fit into engagement holes at different positions on the post, allowing the same connection member design to be used for connecting shelf board members at various heights. This multi-functionality reduces the need for different types of connection members, thereby controlling device complexity while enabling flexible operation.

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.
