Collapsible Restaurant High Chair for Flat Storage and Safe Carrying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional restaurant high chairs are difficult to carry, occupy too much space, and are prone to damage and injury during storage and transport due to their non-collapsible design, which compromises safety and efficiency in restaurant settings.
Innovation Solution
A collapsible high chair design with moveable joints that allows for easy conversion between open and closed forms, enabling safe and ergonomic carrying, convenient storage, and horizontal stacking to reduce the risk of injury and wear, while maintaining stability and safety for children.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional non-collapsible high chair design is used, then structural stability and safety are maintained, but the chair is difficult to carry and occupies large storage space
Solution Approach 1:
The high chair is divided into multiple separable components including the seat assembly, tray assembly, and leg assemblies. These segments can be detached from each other, allowing the chair to be collapsed into a compact configuration for easy carrying and storage, while maintaining full functionality when assembled.
Solution Approach 2:
The high chair incorporates movable joints and collapsible leg assemblies that allow the structure to transition between an expanded stable configuration during use and a collapsed compact configuration for transport and storage. This dynamic capability enables the chair to adapt its volume while maintaining structural integrity.
2Reliability
If traditional non-collapsible high chair design is used, then structural stability during use is maintained, but the chair is prone to damage during storage and transport
Solution Approach 1:
By separating the chair into modular components with detachable connections, the design reduces stress concentration on single joints during transport. The segmented structure allows each component to be handled independently, minimizing the risk of damage to critical joints and fasteners.
Solution Approach 2:
The collapsible design with controlled mechanical joints allows the chair to be safely collapsed and stored in a compact state, reducing exposure to damage during transport. The movable joints are designed to lock securely in both open and closed positions, maintaining reliability while enabling protective collapse.
3Ease of operation
If traditional non-collapsible high chair design is used, then ease of use during meals is maintained, but back injury risk increases during lifting and stacking
Solution Approach 1:
The high chair features collapsible leg assemblies that allow the entire structure to be folded down to a compact height. This enables employees to lift and carry the chair using proper ergonomics, keeping the load close to the body and avoiding bending at the waist, thereby reducing back injury risk while maintaining full functionality when deployed.
4Strength
If traditional non-collapsible high chair design is used, then structural support is maintained, but finger pinching hazard occurs during stacking
Solution Approach 1:
The chair design incorporates detachable leg assemblies that can be separated from the seat unit. This segmentation eliminates the need to stack chairs by nesting them together, thereby removing the finger pinching hazard associated with traditional stacking while maintaining structural support during use through proper assembly.

AI summary
A restaurant and public eating area high chair is a high chair intended for use by infants and small children in restaurants and public eating areas. A restaurant and public eating area high chair consists of two front legs, two back legs, a seat, a backrest, a front bar, and side rails that are high enough to keep the child from falling off of the seat. The collapsible restaurant and public eating area high chair is comprised of the same parts as prior art restaurant and public eating area high chairs, but is built in such a way so that it can fold flat. Folding flat makes the restaurant and public eating area high chair easy to carry, easy to store, and safer to use than prior art restaurant and public eating area high chairs.
