Foldable Restaurant High Chair for Compact Storage and Carrying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing restaurant high chairs are difficult to carry, take up excessive space when stored, and are prone to breakage due to their non-folding design, which complicates storage and transportation, posing safety risks for employees and children.
Innovation Solution
A foldable high chair design with a seat that folds to less than six inches in depth, allowing for ergonomic lifting and horizontal stacking, reducing storage space requirements and minimizing the risk of injury during handling and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a non-folding high chair design is used, then structural stability and safety are improved, but ease of transportation and storage space are worsened
Solution Approach 1:
The high chair is divided into separate functional components: a base unit with leg spreader mechanism and a removable seat assembly. This segmentation allows the seat to be detached for easy storage while the base remains stable, resolving the contradiction between structural integrity and transportation convenience.
Solution Approach 2:
The leg spreader mechanism incorporates movable joints that allow the legs to transition between a compact configuration for storage/transportation and a spread configuration for stable use. This dynamic adjustment enables the chair to adapt its structure based on operational needs, maintaining stability when in use while facilitating easy transportation.
2Reliability
If a non-folding high chair design is used, then structural stability is improved, but storage space requirements are worsened
Solution Approach 1:
By separating the seat assembly from the base unit, the design allows the seat to be removed and stored separately in minimal space, while the base maintains its structural stability. This segmentation dramatically reduces the volume required for storage compared to a complete non-folding chair.
Solution Approach 2:
The collapsible leg mechanism allows the chair to transition from a stable expanded configuration during use to a compact folded configuration for storage, reducing storage volume while preserving structural integrity when deployed.
3Ease of operation
If horizontal support pieces are removed to ease carrying, then ease of operation is improved, but structural stability is worsened
Solution Approach 1:
The horizontal support function is integrated into the leg spreader mechanism itself rather than being separate rigid pieces. The spreader bars connect to the legs through joints that provide both structural support and flexibility for carrying, eliminating the need for separate horizontal support pieces while maintaining both stability and ease of transport.
4Ease of operation
If a foldable design is implemented, then ease of transportation and storage are improved, but device complexity is worsened
Solution Approach 1:
The foldable functionality is achieved through simple segmented components with basic hinge joints rather than complex folding mechanisms. The leg spreader uses straightforward pivot connections that allow collapse without requiring sophisticated locking or latching systems, keeping the overall device complexity low while enabling easy transportation.

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 foldable 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.
