Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable articles, such as chairs and beds, lack the ability to adjust height and sheet width, limiting their versatility and convenience in use.
Innovation Solution
A device combining a connecting and assembling member with an elastic string, featuring multiple combination grooves, allows for adjustable frame angles, enabling height and sheet width adjustments in foldable articles.
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 height and sheet width cannot be adjusted, limiting versatility
Solution Approach 1:
The connecting and assembling member is divided into multiple segments with different combination grooves positioned at various angles and locations. This segmentation allows the frame to be selectively combined at different positions to achieve height and width adjustments while maintaining a modular structure that doesn't significantly increase manufacturing complexity
Solution Approach 2:
The connecting and assembling member is designed with multiple combination grooves that serve multiple functions: they enable both height adjustment and width adjustment, and can be used for different types of frames (leg frames, support frames). This multi-functionality increases versatility without proportionally increasing device complexity
2Adaptability or versatility
If multiple combination grooves are added to enable frame angle adjustment, then adaptability and versatility are improved, but the complexity of the connecting and assembling member increases
Solution Approach 1:
The connecting and assembling member incorporates multiple combination grooves at different angles and positions, transforming a static single-position connection into a dynamic multi-position system. This allows the frame angle to be adjusted according to different usage scenarios while maintaining structural integrity through the elastic string mechanism

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.
