Assembly Shelf Connection Structure for Middle Shelf Repositioning
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 the middle shelf board removal operation in multi-stage assemblies.
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 protrusions/depressions for secure attachment and easy reconfiguration.
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 upper shelf board members
Solution Approach 1:
The connection between shelf board members and the post is segmented through separate connection members that can be independently attached and detached. Each connection member engages with the post through through-holes and with the shelf board through engagement protrusions, allowing individual shelf boards to be accessed and removed without disturbing others.
Solution Approach 2:
Connection members serve as intermediary components between the post and shelf board members. These intermediaries enable independent attachment and detachment of shelf boards by providing separate engagement points, thus facilitating the removal of middle shelf boards without removing upper ones.
2Stability of the object's composition
If shelf board members are securely attached to the post, then structural stability is improved, but reconfiguration and repositioning of middle shelf boards becomes difficult
Solution Approach 1:
The connection system transitions from a static, fixed attachment to a dynamic, reversible connection. Through-holes and engagement protrusions allow connection members to be easily attached and detached, enabling shelf boards to be repositioned or removed while maintaining stable attachment when connected.
Solution Approach 2:
The attachment system is segmented into discrete engagement points (through-holes in the post, engagement protrusions on connection members) that can be independently engaged or disengaged, allowing selective reconfiguration of individual shelf boards while maintaining overall structural stability.

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.
