Foldable Child Play Area Stand with Gear-Linked Legs for Safe Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing child play area stands lack easy accessibility, clear visibility from all angles, and a secure, foldable design that prevents unintentional folding, posing safety and usability challenges.
Innovation Solution
A foldable stand with a main body, a fixed leg, and two movable legs interconnected by a gear mechanism, allowing easy rotation between extended and folded positions, featuring a locking mechanism to prevent unintentional folding and ensuring safe, wide access and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the stand is made foldable to allow easy movement, then mobility is improved, but stability and safety may deteriorate
Solution Approach 1:
The stand employs movable legs that can transition between extended and folded positions through a gear mechanism, enabling the structure to adapt its configuration dynamically. This allows the stand to be mobile when folded and stable when extended, resolving the contradiction between mobility and safety.
Solution Approach 2:
A locking mechanism acts as an intermediary between the movable legs and the main body, preventing unintentional folding while allowing controlled movement. This intermediary component ensures safety during use while preserving the foldable mobility feature.
2Ease of manufacture
If the stand structure is simplified for easy manufacturing, then manufacturing cost is reduced, but visibility and accessibility from all angles may deteriorate
Solution Approach 1:
The stand is divided into a main body and multiple movable legs that can be manufactured separately and assembled through the gear mechanism. This segmentation allows for simpler manufacturing of individual components while the assembled structure provides comprehensive visibility and accessibility from all angles.
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 stand provides easy access, clear visibility, and secure folding, enhancing safety and usability in child play areas by minimizing pinch points and allowing easy movement between positions.
Implementation Method 1
The gear mechanism includes a first gear fixedly attached to the first movable leg, and a second gear fixedly attached to the second movable leg. The first gear and the second gear mesh such that as one of the first and second movable legs is rotated in a first direction, another of the first and second movable legs rotates in a second direction.

AI summary
The present disclosure provides embodiments of a foldable stand for a child play area. The foldable stand includes a main body, a fixed leg fixedly attached to the main body, first and second movable legs movably attached to the main body by a gear mechanism and movable between an extended and a folded position. The gear mechanism includes a first gear fixedly attached to the first movable leg, and a second gear fixedly attached to the second movable leg. The first gear and the second gear mesh such that as one of the first and second movable legs is rotated in a first direction, another of the first and second movable legs rotates in a second direction. The first and second movable legs extend further horizontally from the main body than the fixed leg.
