Foldable small dining chair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing small dining chairs for children require large storage space due to their non-foldable design, making them inconvenient for storage and transportation.
Innovation Solution
A foldable small dining chair design featuring a front support frame and rear support frame that can be folded, with adjustable and detachable armrests, a rotatable seat, and a position-adjustable dining tray, allowing for compact storage and easy assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the small dining chair is designed as a non-foldable structure, then the structural stability and ease of use are improved, but the storage space requirement increases
Solution Approach 1:
The chair is divided into multiple detachable segments including the seat, backrest, armrests, and support frames. These segments can be separated and folded for compact storage, yet reassembled to form a stable chair structure when in use.
Solution Approach 2:
The chair incorporates foldable support frames with hinge joints that allow the structure to transition between an extended stable configuration for use and a folded compact configuration for storage. The dynamic structure maintains stability when assembled and minimizes volume when folded.
2Volume of moving object
If the small dining chair is designed as a foldable structure, then the storage space requirement is reduced, but the device complexity increases
Solution Approach 1:
By dividing the chair into standardized modular segments with consistent connection interfaces, the complexity of each individual component is reduced. The segmentation allows for simple foldable mechanisms in each section while maintaining overall structural integrity.
Solution Approach 2:
The support frames serve multiple functions: they provide structural support when extended, enable folding for compact storage when collapsed, and include integrated features like armrest mounting and seat attachment. This multi-functionality reduces the need for separate components.
3Ease of operation
If the armrests are made detachable and foldable, then the ease of operation and storage convenience are improved, but the manufacturing complexity increases
Solution Approach 1:
The armrests are designed as separate detachable segments that can be independently manufactured and then assembled to the support frames using standardized connection mechanisms, simplifying both manufacturing and assembly processes.
Solution Approach 2:
The foldable armrests are designed to nest within or alongside the support frame structure when folded, utilizing the existing structural space rather than requiring additional separate components, thereby reducing manufacturing complexity.
