Ladder structure for frame bed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional ladder structures for frame beds are unsafe due to their steep vertical placement, which can lead to falls and unbalanced forces on the frame bed, causing instability and potential deformation.
Innovation Solution
A ladder structure for a frame bed is designed with an oblique placement, featuring two side bars with transverse step bars, and a connecting member that secures the ladder to the frame bed's columns, dispersing weight and preventing the ladder from being pulled out.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the ladder is placed vertically to save space and maintain compact structure, then the structure occupies less space, but the ladder becomes too steep making it unsafe to climb and causing unbalanced forces on the frame bed
Solution Approach 1:
The patent changes the ladder's orientation from a vertical arrangement to an oblique arrangement, transitioning the structure into a different spatial dimension. This oblique placement at an angle between 15-45 degrees allows the ladder to distribute weight more effectively across the frame bed while providing a safer climbing angle, thus resolving the contradiction between structural stability and climbing ease.
2Device complexity
If the ladder is placed vertically with all weight on one side, then the structure remains simple, but unbalanced forces cause the frame bed to shake and become loose over time
Solution Approach 1:
The patent employs counterbalancing forces by positioning the ladder obliquely and using connecting members attached to multiple columns. This creates opposing forces that balance the weight distribution, preventing the unbalanced lateral forces that would otherwise cause the frame bed to shake and become loose, thereby improving reliability without significantly increasing complexity.
3Ease of operation
If the ladder is positioned to allow easy access to the upper bunk, then climbing becomes convenient, but the ladder may be accidentally pulled out or kicked, creating safety hazards
Solution Approach 1:
The patent applies preliminary anti-action by pre-installing connecting members that securely attach the ladder to the frame bed columns before any accidental displacement can occur. These connecting members prevent the ladder from being pulled out or kicked, addressing the safety hazard in advance while maintaining the ladder's accessibility for climbing.
4Reliability
If the connecting member is positioned higher for better structural support, then the ladder is more securely held, but it may trip the user when climbing
Solution Approach 1:
The patent applies local quality by positioning the connecting members at a specific height range (below the lower bunk frame height) that optimizes both structural support and user safety. This localized adjustment ensures the connecting members provide secure attachment while remaining low enough to prevent tripping hazards during climbing, thus resolving the contradiction between reliability and safety.

AI summary
A ladder structure for a frame bed comprises a ladder and a connecting member. The ladder comprises two side bars symmetrically located on a left side and a right side of the ladder and a plurality of transverse step bars connected to the two side bars and spaced apart from one another along a length direction of the side bars. An upper end of each of the two side bars of the ladder is connected to a side of an upper bunk frame. The ladder is disposed obliquely. Lower ends of the two side bars of the ladder are supported on the ground. A first end of the connecting member is connected to at least one of the two side bars of the ladder, and a second end of the connecting member is connected to a column of the plurality of columns which is most adjacent to the ladder.
