Bed Column and Lateral Rod Assembly Structure Using Multi-Bolt Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional connection methods for iron frame bed columns and lateral rods are loose, prone to shaking, and unsafe for consumer assembly due to lack of welding tools and skills, with existing sleeve connections being inconvenient and not sufficiently firm.
Innovation Solution
A novel assembly structure featuring a bed column with an upper and lower column, a joint section with a positioning step, and a locking piece on the lateral rod locked by upper and lower bolts, with an optional reinforcing bolt, forming a firm T-shaped structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a hook and hanging ring connection method is used, then the assembly is simple and does not require welding tools, but the connection is loose and the lateral rod easily shakes
Solution Approach 1:
The connection structure is divided into multiple functional parts: a connecting sleeve with positioning steps for location fixation, and a locking piece with multiple holes for bolt connection. This segmentation allows the simple assembly process to achieve firm connection through coordinated action of different components.
Solution Approach 2:
The connecting sleeve acts as an intermediary component between the column and lateral rod. It provides a positioning step that guides the lateral rod into correct position, while the locking piece serves as another intermediary that translates simple bolt insertion into firm mechanical locking, eliminating the shaking problem without requiring welding.
2Reliability
If a connecting sleeve is used to sleeve onto the column from top to bottom, then the connection is improved, but the assembly operation becomes inconvenient due to the large column length
Solution Approach 1:
The column connection is segmented into multiple positioning steps along its length. The first positioning step receives the connecting sleeve during assembly, allowing the sleeve to be installed without sliding the entire length of the long column. This segmentation makes the assembly operation convenient while maintaining connection firmness.
Solution Approach 2:
The positioning steps are pre-formed on the column at specific locations. When assembling, the connecting sleeve is guided into the first positioning step which is already in place, eliminating the need to manually align and slide the sleeve along the entire column length. This preliminary preparation of positioning features greatly simplifies the assembly operation.
3Ease of manufacture
If the connecting sleeve is used with a multi-section column structure, then the column can be assembled in sections, but the connection is not firm because the sleeve does not sleeve the assembly position
Solution Approach 1:
Both the column (multi-section structure) and the connecting sleeve system are segmented. The column has multiple positioning steps at different heights, and the connecting sleeve has multiple holes. When assembling multi-section columns, the sleeve can be positioned at the appropriate positioning step corresponding to the joint location, ensuring firm connection at the assembly position while maintaining assembly flexibility.
Solution Approach 2:
The connecting sleeve design is universal and can accommodate multi-section column structures. The positioning steps are designed to work with section joints, and the locking piece with multiple holes can be oriented to lock the sleeve at any position. This multi-functional design ensures firm connection at assembly positions while maintaining the flexibility of multi-section construction.
4Ease of operation
If traditional hook connection is used, then no welding is required for consumer assembly, but the connection is very loose and unsafe
Solution Approach 1:
The connecting sleeve and locking piece are designed to be self-contained assembly components that consumers can install without external tools or specialized skills. The positioning steps guide the assembly process automatically, and the locking piece with holes aligns with bolts to create self-locking action. This self-service design maintains consumer assembly feasibility while achieving safe, firm connections through the coordinated geometry of the components.

AI summary
An assembly structure for a bed column and a lateral bed rod is provided. The bed column is arranged vertically and comprises an upper column and a lower column. The lower column comprises a joint section. The upper column is sleeved on the joint section and is stopped at a positioning step formed at a bottom end of the joint section. The lateral bed rod is horizontally, laterally arranged. The lateral bed rod is connected with a locking piece adjacent to a side of the positioning step and abutting the upper column and the lower column. A first portion of the locking piece is locked with an upper bolt enabling the locking piece, the upper column, and the joint section to be locked together. A second portion of the locking piece is locked with a lower bolt enabling the locking piece and the lower column to be locked together.
