Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable articles lack the ability to adjust their frame angles, height, and sheet width, limiting their versatility and comfort during use.
Innovation Solution
A device with multiple combination grooves in the connecting and assembling member allows for adjustable frame angles and sheet width adjustments, using elastic strings and leg frames to enhance flexibility and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a frame is combined with one designated portion of a connecting and assembling member in existing foldable articles, then the structure is simple and easy to manufacture, but the frame angle cannot be adjusted and the article lacks versatility
Solution Approach 1:
The connecting and assembling member is segmented into multiple combination grooves positioned at different angles and locations. This segmentation allows the frame to be combined at multiple discrete positions, enabling frame angle adjustment while maintaining a relatively simple overall structure. Each groove represents a segmented option for frame placement.
Solution Approach 2:
The connecting and assembling member transitions from a static, fixed-frame-position design to a dynamic, adjustable-frame-position design. The multiple combination grooves enable the frame angle to be dynamically adjusted between different predetermined positions, making the foldable article adaptable to different usage scenarios.
2Adaptability or versatility
If the foldable article is configured for folding after use, then storage and transportation are convenient, but the height and sheet width cannot be adjusted during use
Solution Approach 1:
The frame configuration is segmented into multiple combination grooves at different positions and angles. This segmentation enables independent adjustment of frame height and sheet width by selecting different groove positions, allowing the article to be customized for different user needs while maintaining the foldable structure for convenient storage.
Solution Approach 2:
The connecting and assembling member with multiple combination grooves serves multiple functions: it enables frame angle adjustment, height adjustment, and sheet width adjustment. This multi-functional design allows a single component to provide various adjustment capabilities without requiring separate mechanisms for each function.
3Adaptability or versatility
If the mat sheet or bed sheet is installed on upper portions of the frames, then the basic function is provided, but the sheet width cannot be narrowed or widened and it cannot be tightened or loosened
Solution Approach 1:
The connection system is segmented into multiple combination grooves positioned at different locations on the connecting and assembling member. This segmentation allows the sheet width to be adjusted by combining the frame at different groove positions, and the sheet tightness can be adjusted by selecting grooves at appropriate distances from each other.

AI summary
Provided is a device for changing a frame angle of a foldable article. The device combines frames using a connecting and assembling member and an elastic string and makes up a leg or a support frame of the foldable article. The connecting and assembling member with which a first end of the elastic string is combined and which has multiple combination grooves in such a manner that the frame combined with a second end of the elastic string is selectively combined with the connecting and assembling member. The first end of elastic string is combined with the connecting and assembling member, and the second end of the elastic string is combined with the frame such that the frame can be elastically operated. The frame is combined with the first end of the elastic string and is elastically insertable into or separable from the connecting and assembling member.
