Bed Ladder Insertion-Based Frame Clamping for Tool-Free Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional bed ladder installation methods, such as welding and bolt locking, are inconvenient for transportation, difficult to disassemble, and often require multiple people to ensure stability and firmness during installation.
Innovation Solution
A bed ladder design that uses an upper and lower frame transverse bar to clamp the ladder in place, allowing for easy assembly and disassembly, and providing stability and firmness without the need for welding or complex bolt systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If welding is used to fix the ladder to the bed frame, then the firmness and stability of the ladder is improved, but the convenience for transportation and disassembly deteriorates
Solution Approach 1:
The connection between the ladder and bed frame is divided into separate components: the ladder with insertion holes and the bed frame transverse bars. This segmentation allows the ladder to be easily inserted and removed while maintaining connection stability during use, resolving the contradiction between firmness and disassembly convenience.
2Ease of operation
If bolt locking is used to install the ladder, then the convenience for disassembly is improved, but the firmness and stability deteriorates due to easy loosening
Solution Approach 1:
The connection mechanism extracts the problematic bolt locking system and replaces it with a direct insertion system where the ladder handrails are inserted into holes in the transverse bars. This eliminates the loosening issue of bolts while maintaining easy disassembly capability.
3Device complexity
If traditional installation methods are used, then the structural simplicity is maintained, but the difficulty of independent installation increases due to need for multiple people
Solution Approach 1:
The ladder installation system enables self-service installation through its simple insertion mechanism. The ladder handrails are designed to be directly inserted into pre-positioned holes in the transverse bars, allowing one person to complete the installation without needing others to hold or support the ladder during the process.

AI summary
A bed ladder configured to be installed on a bed frame comprises an upper frame transverse bar and a lower frame transverse bar, and the upper frame transverse bar and the lower frame transverse bar are parallel to each other and located on a vertical plane. The bed ladder comprises two handrails symmetrically arranged in a left-and-right direction and a plurality of step bars connected to the two handrails, and the bed ladder is vertically arranged. The upper frame transverse bar and the lower frame transverse bar cooperate with each other to clamp the bed ladder to inhibit movement of the bed ladder in a vertical direction, and an upper end of each of the two handrails is connected to the upper frame transverse bar in an inserted manner. A lower end of each of the two handrails is connected to the lower frame transverse bar in an inserted manner.
