High Chair Folding Pivot for Simpler Frame Locking
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 folding device with a pivoting mechanism between the front and rear leg frames, featuring a folding body, an engaging member, a driving member, and an elastic element, allows the high chair frame to transition between open and folded positions with ease by disengaging the engaging member, enabling simpler operation and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional high chairs use additional supportive frames and complex folding mechanisms, then the high chair can maintain structural stability, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent removes the additional transverse supportive frame from the high chair structure. The folding mechanism is simplified by eliminating the complex engagement devices that were previously needed to lock and unlock the leg frames. The rear leg frame is directly pivotally connected to the front leg frame, allowing folding without requiring separate supportive frames or complex locking mechanisms.
Solution Approach 2:
The high chair frame is divided into distinct segments: front leg frame, rear leg frame, and seat assembly. Each segment can move independently relative to the others, with the rear leg frame pivoting relative to the front leg frame. This segmentation allows the structure to fold compactly while maintaining stability when assembled.
2Productivity
If conventional high chairs require direct operation on folding devices at the supportive frame, then the folding function can be achieved, but the ease of operation deteriorates due to complicated mechanisms
Solution Approach 1:
The patent eliminates the need for separate folding devices and engagement mechanisms that were previously located at the supportive frame. The folding function is achieved through the direct pivotal connection between the rear leg frame and front leg frame, which allows natural folding motion without requiring additional operational components.
3Stability of the object's composition
If conventional high chairs use fixed length transverse supportive frames, then the relative position between front and rear leg frames is maintained, but the ease of manufacture and storage deteriorates due to inability to fold the supportive frame
Solution Approach 1:
The patent removes the fixed length transverse supportive frame entirely. Instead, the relative position and stability between front and rear leg frames is maintained through the pivotal connection design and the inherent structural geometry of the leg frames themselves, eliminating the need for separate supportive frames that would require folding capabilities.
Solution Approach 2:
The connection between front and rear leg frames is made dynamic through pivotal joints, allowing the structure to transition between fixed (when assembled) and folded (when disassembled) states. This dynamic connection replaces the static fixed-length supportive frame, providing both stability during use and compactness for storage.
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
The solution simplifies the folding process by eliminating the need for additional supportive frames and direct operation on folding devices, making it easier for users to fold and store the high chair without complexity.
Implementation Method 1
an elastic element, connected between the engaging member and the rear leg frame
Implementation Method 2
a friction member, configured on the pivoting section of the rear leg frame and engaged with the folding body to prevent the pivoting section from pivoting relative to the folding body

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.
