Assembly Shelf Connection Structure for Removable Middle Shelves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing assembly shelves require 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 protrusions/depressions for secure attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a single post is used to connect multiple shelf board members, then assembly is simplified and design is improved, but middle shelf board members 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 individual connection members that can be independently engaged or disengaged. Each shelf board member has its own connection members with engagement protrusions that fit into engagement holes in the post, allowing selective removal without affecting other shelf board members.
Solution Approach 2:
Connection members serve as intermediary elements between the shelf board members and the post. These connection members include engagement protrusions that fit into engagement holes in the post, enabling independent engagement and disengagement of individual shelf board members while maintaining the overall structural integrity of the shelving unit.
2Stability of the object's composition
If shelf board members are securely attached to the post, then structural stability is improved, but repositioning or removal of middle shelf board members requires disassembly of the entire structure
Solution Approach 1:
The connection system transitions from a static, fixed attachment to a dynamic, selectively engageable connection. Connection members can be easily engaged by inserting engagement protrusions into engagement holes or disengaged by pulling them out, allowing shelf board members to be quickly repositioned or removed without time-consuming disassembly of the entire shelving structure.
Solution Approach 2:
The attachment system is segmented into independent connection members for each shelf board member. Each connection member can be independently engaged or disengaged from the post, enabling selective repositioning of individual shelf board members without affecting the stability or position of other shelf board members in the 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.
