High Chair Folding Joint for Simple One-Press Collapse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high chairs require complex mechanisms and additional supportive frames to fold, making them difficult to use and store.
Innovation Solution
A high chair design featuring a frame body with a front leg frame and rear leg frame that are pivotally connected, incorporating a folding device with a folding body, engaging member, and elastic element to simplify the folding process by allowing the frames to pivot and lock in place without needing additional supportive frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If additional supportive frames are added to enable folding, then the high chair can be folded, but the device complexity increases and ease of operation decreases
Solution Approach 1:
The patent removes the additional transverse supportive frame from the high chair structure. Instead, it uses the existing rear leg frame that pivots relative to the front leg frame, eliminating the need for separate folding mechanisms and supportive frames while maintaining folding capability.
Solution Approach 2:
The rear leg frame serves dual functions: it provides structural support when engaged and enables folding when disengaged. This multi-functional design eliminates the need for dedicated folding mechanisms, reducing overall device complexity while maintaining adaptability.
2Adaptability or versatility
If direct operation on folding device at supportive frame is required, then folding can be achieved, but ease of operation becomes difficult
Solution Approach 1:
The engaging member automatically engages with the rear leg frame through elastic force when the high chair is assembled, and automatically disengages when folding force is applied. This self-servicing mechanism eliminates the need for complex direct operation on folding devices, making the folding process simpler and more user-friendly.
3Adaptability or versatility
If conventional folding mechanisms are used, then the high chair can be folded, but storage difficulty increases due to complexity
Solution Approach 1:
By removing the transverse supportive frame and its associated folding mechanisms, the patent simplifies the overall structure to essential components only. This extraction of unnecessary elements makes the high chair easier to manufacture, assemble, and store, while maintaining the essential foldability function.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy operation and compact folding of the high chair by allowing the frame body to transition between open and folded positions with a user-friendly mechanism, reducing complexity and storage challenges.
Implementation Method 1
an elastic element to move the engaging member between an engaged position and a disengaged position
Implementation Method 2
The frame body includes a front leg frame and a rear leg frame pivotally connected to each other

AI summary
A folding device is configured at the pivot between the rear leg frame and the front leg frame of a high chair and allows a user to complete folding process by pressing a driving member. When the driving member is pressed, an engaging member of the folding device moves correspondingly to an unlocked position, so that the rear leg frame disengages from and pivots about the front leg frame. The high chair can then be folded easily for the user, and the structure of the invention is simpler than the prior art.
