Collapsible High Chair Frame With Spring Fasteners for Compact Packing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional high chairs occupy large volumes during storage and transportation, leading to wasteful use of space and increased costs.
Innovation Solution
A collapsible high chair design featuring pivotally connected frames with V-shaped spring fasteners allows the chair to be easily disassembled and compactly stacked, comprising a front frame with U-shaped tubes and a rear frame with U-shaped tubes, enabling transformation between expanded and collapsed states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a conventional high chair is designed with a fixed structure, then it provides stable support and ease of manufacture, but it occupies large storage and transportation space
Solution Approach 1:
The high chair frame is divided into multiple detachable sections including front frame, rear frame, seat, and tray components. These segments can be separated and stored independently, dramatically reducing storage volume while maintaining structural integrity during use
Solution Approach 2:
The high chair incorporates movable and adjustable components such as pivotally connected frames, sliding seat mechanisms, and detachable fastening devices. These dynamic elements allow the chair to transform between expanded functional state and collapsed storage state
2Volume of moving object
If a collapsible high chair with detachable components is designed, then storage space is reduced, but the device complexity and number of fastening devices increase
Solution Approach 1:
V-shaped spring fasteners are employed that automatically engage with tubes when the frame is assembled and can be easily released by applying pressure. This self-servicing mechanism eliminates the need for separate locking operations, making the complex detachable structure easy to assemble and disassemble
Solution Approach 2:
The fastening mechanism utilizes elastic deformation of spring arms to create automatic engagement and disengagement. By changing the physical state of the fastening components from rigid to elastic, the system achieves both secure connection during use and easy detachment for storage
3Productivity
If the high chair is designed to be detachably collapsible, then storage and transportation efficiency is improved, but the ease of operation for assembly and disassembly may be affected
Solution Approach 1:
The V-shaped spring fasteners automatically engage with the tube structures when components are brought together, eliminating the need for manual locking operations. Users simply need to align and press components together, making assembly intuitive and easy despite the collapsible design
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 collapsible design significantly reduces storage and transportation space requirements, facilitating easier handling and cost savings by allowing the chair to be compactly packaged when not in use.
Implementation Method 1
each of the fastening devices is a substantially V-shaped spring fastener having two elastic arms

AI summary
A collapsible high chair is provided. The collapsible high chair comprises a front frame including a pair of middle front tubes and a substantially U-shaped lower front tube, the pair of middle front tubes and the lower front tube being detachably engaged with each other by fastening devices; and a rear frame including a substantially U-shaped upper rear tube and a substantially U-shaped lower rear tube, the upper rear tube and the lower rear tube being detachably engaged with each other by fastening devices. The front frame and the rear frame are pivotally connected to each other so that the front frame and the rear frame pivot and approach with respect to each other, thereby allowing the high chair to be in a collapsed state.
