Height-adjustable child support device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing children's entertainer seats, such as bouncers and jumpers, often lack sufficient height adjustment range and ease of adjustment, failing to accommodate children of different sizes as they grow.
Innovation Solution
A height-adjustable child support device featuring a base member with upright frame members and support members that can be adjusted in height by a coupling component engaging with a receiving component, allowing the seat tray to be raised or lowered through a range of positions using a guiding channel and tension from the child's weight to maintain the selected height.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the support height is fixed, then the device structure is simple, but it cannot accommodate children of different sizes
Solution Approach 1:
The support members are made adjustable in length through a coupling component that can engage with receiving components at multiple positions along the upright frame members. This dynamic adjustment capability allows the entertainer to adapt to children of different sizes while maintaining a relatively simple overall structure.
Solution Approach 2:
The support members are divided into segments that can be adjusted independently. The coupling component can engage with receiving components at different positions, creating discrete height settings. This segmentation provides multiple height options without requiring a completely complex continuous adjustment mechanism.
2Adaptability or versatility
If the support height is adjustable, then it can accommodate growing children, but the adjustment mechanism becomes complex
Solution Approach 1:
The coupling component is designed to be movable along the upright frame members, allowing easy engagement and disengagement from receiving components at different heights. This dynamic design enables simple height adjustment operations while providing full adaptability for growing children.
Solution Approach 2:
The tension from the child's weight automatically helps maintain the selected height position once the coupling component engages with a receiving component. The system uses the load itself to stabilize the adjustment, reducing the need for complex locking mechanisms or additional adjustment aids.
3Adaptability or versatility
If multiple adjustment positions are provided, then the height range is sufficient, but the device complexity increases
Solution Approach 1:
The upright frame members include receiving components at multiple discrete positions, and the coupling component can engage with any of these positions. This segmented approach provides sufficient height range for different child sizes while keeping each individual adjustment position simple and manageable.
Solution Approach 2:
The coupling component serves multiple functions: it connects the support member to the frame, allows height adjustment by engaging with different receiving components, and provides stability through tension engagement. This multi-functionality reduces the need for separate mechanisms for each function, thereby reducing overall complexity despite providing multiple height positions.

AI summary
A child support device (100) is provided with a height that is easily adjustable. The child support device (100) includes a seat assembly (145) suspended from at least one upright frame member (120) extending above the seat assembly (145) by at least one support member (130). The upright frame member (120) includes a cap (150) through which the support member (130) is threaded. The height of the seat assembly (145) is vertically adjustable by repositioning engagement of the support member (130) with the at least one upright frame member (120).
