Adjustable Ride-On Toy Seatback With Multi-Position Snap Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ride-on toys for children often lack adjustable seating options, which can lead to discomfort and reduced usability as children grow, limiting their adaptability to different rider sizes and preferences.
Innovation Solution
A ride-on toy, such as a tricycle, featuring an adjustable seatback that can be securely positioned in multiple locations using a combination of hooks and resilient snaps, allowing for easy installation and removal, ensuring a comfortable fit for children of varying heights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed seatback design is used, then the device complexity is reduced, but the adaptability to different child sizes is poor
Solution Approach 1:
The seatback is divided into multiple positionable segments along a vertical track, allowing independent adjustment of each segment to match different child sizes and developmental stages
Solution Approach 2:
The seatback transitions from a static fixed design to a dynamic adjustable design, where the height and angle can be modified as the child grows, providing ongoing adaptability without replacing the entire seat
2Adaptability or versatility
If an adjustable seatback mechanism is added, then the adaptability to different child sizes is improved, but the device complexity increases
Solution Approach 1:
The adjustment mechanism provides more positioning options than strictly necessary, allowing caregivers to easily adjust to the nearest suitable position without requiring precise measurement, simplifying the user interaction despite the complex underlying mechanism
3Duration of action of moving object
If the seatback is made adjustable for growth accommodation, then the duration of use is extended, but the manufacturing precision requirements increase
Solution Approach 1:
The seatback is segmented into discrete adjustable positions with standardized connection points, allowing manufacturing at lower precision levels while still providing multiple fixed positions that accommodate growth over time
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 adjustable seatback provides enhanced comfort and adaptability, accommodating children of different sizes and promoting extended use by allowing the seatback to be easily adjusted and secured in various positions, enhancing the overall riding experience.
Implementation Method 1
a resilient snap (36a, 36b) positioned to engage a hole (42a, 42b) when the seatback is installed in the selected position

AI summary
A vehicle includes a seating platform featuring a first pair of scat mounting holes, a second pair of seat mounting holes positioned rearward of the first pair of seat mounting holes and a third pair of seat mounting holes positioned rearward of the second pair of seat mounting holes. A seatback is provided with a pair of hooks and a pair of snaps. Each of the snaps includes a catch portion. The hooks and snaps are adapted to engage the first and second pair of seat mounting holes to secure the seatback in a first position. The hooks and snaps are also adapted to engage the second and third pair of seat mounting holes to secure the seatback in a second position.
