Stackable Plastic Booster Seat With Lumbar Support and Anti-Slide Seat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional booster seats are not stackable, lead to poor posture in children, have unstable height adjustment mechanisms, and often cause children to slide forward, compromising safety and comfort.
Innovation Solution
A molded booster seat with an angled rearward and downward seat surface and integrated lumbar support, featuring cylindrical corner portions for stable stacking and adjustable feet for height adjustment, ensuring the seat remains upright and secure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional booster seats are designed with a curved back extending from side to side, then the seat structure is simplified, but the child develops poor posture with head down and shoulders drawn in
Solution Approach 1:
The backrest is divided into different zones with distinct functions: an upper curved portion for comfort and a lower lumbar support portion for posture. This local differentiation allows each zone to perform its specific function optimally without compromising overall structural simplicity.
Solution Approach 2:
The backrest is segmented into multiple functional regions including the lumbar support area with increased depth and the upper backrest area. This segmentation enables the lumbar support to independently promote proper posture while the rest of the structure maintains simplicity.
2Ease of manufacture
If conventional booster seats have a horizontal or downward-sloping seating surface, then manufacturing is simpler, but the child easily slides forward against the safety bump
Solution Approach 1:
Instead of having the seating surface slope forward as in conventional designs, the seat surface is inverted to slope rearwardly and downwardly. This reversal of the slope direction uses gravity to pull the child away from the safety bump and toward the lumbar support, preventing forward sliding while maintaining manufacturing simplicity.
3Productivity
If conventional booster seats are stacked for storage, then space is conserved, but the stack begins to lean and collapse
Solution Approach 1:
The corner portions of the base are designed with cylindrical curvature instead of sharp angles. This curvature allows the corners to nestle into corresponding spaces when seats are stacked, creating a stable interlocking arrangement that prevents leaning and collapsing while maintaining compact storage.
4Adaptability or versatility
If conventional booster seats include height adjustment mechanisms, then adaptability is improved, but the mechanism is troublesome to operate or provides unstable seat
Solution Approach 1:
The feet are designed to be vertically adjustable through slots in the base, allowing dynamic height adaptation. The feet can be positioned at different heights within the slots and secured, providing both adaptability and stability without complex mechanisms.
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 booster seat is stackable, promotes good posture, provides stable and adjustable seating, and enhances safety by preventing children from sliding forward, while being easy to clean and cost-effective to manufacture.
Implementation Method 1
the molded seat having a seat surface angled rearwardly and downwardly such that gravity tends to draw the child away from a safety bump on the molded seat and toward the molded back

AI summary
A stackable plastic booster seat apparatus with a body having a set of four corner cylindrical portions. A right foot having cylindrical portions engages two of the corner cylindrical portions and a left foot engages the other two corner cylindrical portions. The body includes a back with a lumbar support, a seat with a safety bump and a downward and rearward slope such that a child tends to sit properly in the apparatus away from the safety bump and against the lumbar support.
