Connecting mechanism for adjustable bed frame and adjustable bed frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bed frames are not adjustable in width, making them inconvenient to use and occupy excessive space during transportation and storage, and the existing adjustable structures lack intuitive adjustment mechanisms and efficient packaging dimensions.
Innovation Solution
A connecting mechanism with a connecting member and positioning member, featuring perforations and slots, allows for easy adjustment and fixation of lateral bars to form a bed frame of desired width, with visible dimensions and minimal packaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If lateral bars are made monolithic and slidably connected, then the bed frame width is adjustable, but the packaging dimension cannot be minimized
Solution Approach 1:
The lateral bars are divided into multiple sections that can be separated and packaged independently. Each lateral bar consists of at least two segments that can be disconnected, allowing them to be packaged in a compact state rather than requiring full extension space, thus minimizing packaging dimensions while maintaining adjustability functionality.
Solution Approach 2:
The lateral bar segments are designed to nest within each other when disconnected, similar to nested dolls. The smaller segments can be inserted into larger segments, creating a compact packaged form that minimizes volume while preserving the ability to extend to various widths when assembled.
2Volume of moving object
If lateral bars are divided into multiple sections, then the packaging dimension is minimized, but the lateral bars may not be freely placed
Solution Approach 1:
The connecting members are pre-equipped with positioning structures such as guide rails, alignment features, or marked positioning points that indicate where each lateral bar segment should be placed. This preliminary preparation ensures that even though the bars are segmented, they can be quickly and easily reassembled in the correct configuration without requiring complex alignment procedures.
Solution Approach 2:
Connecting members serve as intermediaries between lateral bar segments, providing standardized interfaces with positioning features that guide proper placement. These connecting members include elements like alignment pins, guide slots, or marked reference points that mediate the assembly process, making it easy to place segments correctly even when divided into multiple sections.
3Adaptability or versatility
If adjustable structure has no limit for levels, then the width can be freely adjusted, but it is not intuitive for consumers and adjustment is not quick
Solution Approach 1:
The connecting members are pre-equipped with positioning structures such as guide rails, alignment features, or marked positioning points that indicate where each lateral bar segment should be placed. This preliminary preparation ensures that even though the bars are segmented, they can be quickly and easily reassembled in the correct configuration without requiring complex alignment procedures.
Solution Approach 2:
Specific portions of the connecting members and lateral bars are provided with distinctive positioning features, markings, or color-coded indicators at key adjustment locations. These localized quality enhancements make it intuitive for consumers to identify correct positioning points quickly, enabling fast and accurate width adjustment without requiring the user to understand the entire adjustment mechanism.
4Ease of operation
If lateral bars are engaged with locking members, then the width is fixed after adjustment, but the connection strength at junctions is reduced
Solution Approach 1:
The locking function and connection function are merged into a single integrated connecting member design. The connecting member simultaneously provides both the structural connection between lateral bar segments and the locking mechanism to fix the width, eliminating the need for separate locking components that would create additional stress concentration points and reduce overall connection strength.
