Oblong Connector Casing Design for Stable Bed Frame Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bed frames experience instability and deformation due to weak connections between metal sheets and peripheral frames, leading to uneven surfaces and discomfort.
Innovation Solution
The use of oblong cross-section connectors with casings and slots that prevent translational movement of third bars, along with chamfered edges and upper/lower corner segments to enhance stability and secure connections between bars, creating a more robust frame unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If metal sheets are inserted into holes formed at the peripheral frame to connect interior bars with the peripheral frame, then the bed frame can be assembled, but the connections are not robust and the metal sheets bend or deform after multiple assembling/disassembling operations or long time use
Solution Approach 1:
The connector is divided into multiple functional segments: a body portion that connects to the peripheral frame, a casing portion that receives the bar end, and a slot mechanism that enables controlled insertion and removal. This segmentation allows the connector to provide both ease of assembly through the slot-guided insertion process and reliable connection through the integrated casing structure that prevents deformation.
2Ease of manufacture
If conventional metal sheet connections are used, then assembly is simple, but the bed surface becomes sloped or uneven after use, making the bed unusable or uncomfortable
Solution Approach 1:
The connector is pre-configured with a casing and slot structure that guides the bar end into precise alignment during assembly. The oblong cross-section with specific width and length dimensions is designed beforehand to ensure proper positioning. This preliminary structural preparation ensures that the bed surface remains flat and level after assembly, eliminating the need for post-assembly adjustments while maintaining manufacturing simplicity.

AI summary
A frame unit includes first and second bars spaced apart from each other, third bars disposed between the first and second bars, and connectors removably connecting the third bars with the first and second bars. A connector includes a body fixedly connected with the first or second bar, a casing defining an interior to receive an end of a third bar, and a slot allowing insertion of the end of the third bar into the casing. The interior defined by the casing has narrow and wide sides corresponding to the narrow and wide sides of the end of the third bar. As such, when the end of the third bar is inserted into the casing, the end of the third bar is prevented from any translational movement within the casing. The connectors allow quick and easy connection of bars, and in the meantime enhance the stability of the frame unit.
