Convertible bedside bassinet and changing table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant care products, such as cribs and changing tables, often require excessive space and lack versatility, making it difficult for parents to monitor infants in the same room without multiple separate items, and existing mobile products lack effective braking and height adjustment mechanisms.
Innovation Solution
A convertible bassinet with a mobile support system featuring a braking apparatus and vertical adjustment mechanism, allowing it to be securely positioned and easily reconfigured between a bassinet and changing table surface, incorporating a moveable perimeter frame and resilient connectors for easy height adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate infant care products (crib, bassinet, changing table) are used to provide comprehensive care functions, then the versatility and functionality are improved, but the space required in the bedroom increases significantly
Solution Approach 1:
The patent combines multiple infant care functions (bassinet for sleeping, changing table for diaper changes, and storage) into a single integrated mobile unit. The bassinet platform can be positioned at different heights and configurations to serve as both a sleeping area and a changing surface, eliminating the need for separate cribs and changing tables in the bedroom.
Solution Approach 2:
The mobile bassinet unit is designed with multi-functional capabilities: it serves as a sleeping bassinet when the platform is in the upper position, transforms into a changing table when the platform is lowered, and includes integrated storage compartments. This universal design allows one piece of furniture to replace multiple separate care products.
2Ease of operation
If the bassinet is made mobile to allow easy repositioning and reconfiguration, then the ease of operation and adaptability are improved, but the stability and safety during use may be compromised
Solution Approach 1:
The mobile bassinet incorporates a dynamic braking system with foot-actuated brakes that allow the unit to be easily moved when needed but provide stable locking when positioned. The brakes engage automatically when the bassinet is stationary, transforming the mobile unit into a stable, fixed position for safe infant care activities.
Solution Approach 2:
The patent introduces intermediary components including a mobile platform with wheels for easy movement, a braking mechanism for stable positioning, and an adjustable platform with locking pins for height adjustment. These intermediaries enable the bassinet to transition smoothly between mobile and stationary states, maintaining both ease of repositioning and operational stability.
3Adaptability or versatility
If the bassinet platform height is made adjustable to accommodate different care activities, then the adaptability for different uses is improved, but the device complexity increases
Solution Approach 1:
The bassinet platform height adjustment mechanism is segmented into discrete height levels with corresponding locking positions. The platform can be raised or lowered to specific predetermined heights using a simple pin-and-hole locking system, allowing easy adjustment between bassinet height and changing table height without complex continuous adjustment mechanisms.
Solution Approach 2:
The height adjustment mechanism is designed to be self-servicing through gravity-assisted lowering and simple manual locking. The platform can be lowered by releasing the locking pin and allowing gravity to guide it to the next locking position, reducing the need for motors or complex mechanical advantage systems.
4Reliability
If a braking mechanism is added to the mobile bassinet to prevent unintended movement, then the safety and reliability are improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The braking mechanism uses simple, inexpensive components such as foot-actuated drum brakes or caliper brakes with basic friction materials. These are straightforward mechanical components that provide reliable stopping power without requiring complex electronic controls, sensors, or expensive materials, making the safety feature cost-effective to manufacture.
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 solution provides a space-efficient, durable, and easy-to-use infant care product that can be selectively positioned and reconfigured, ensuring safety and convenience for caregivers by allowing secure movement and adjustable height settings.
Implementation Method 1
Resilient connectors between the position actuator and the perimeter frame members bias the top perimeter frame toward the uppermost position or the lowermost position based on movement of the position actuator
Implementation Method 2
A mobile bassinet having means to adjust the height of the bassinet as well capability to be reconfigured to provide a changing table surface would be useful and beneficial to users. Mobile products require braking mechanisms to prevent unintended movement when a child is placed thereon

AI summary
A convertible bassinet including a mobile support enabling selective movement about a supporting surface and a braking apparatus providing the ability to secure the mobile support in a laterally fixed position on the surface. The mobile support also includes a vertical adjustment mechanism enabling the height of the bassinet to be altered by a user. The bassinet further includes a top perimeter frame with a position actuator for varying the height of the top perimeter frame above a child supporting surface. When in an uppermost position the perimeter frame defines a bassinet. A changing table surface is defined when the perimeter frame is repositioned to a lowermost position. Resilient connectors between the position actuator and the perimeter frame members allow the top perimeter frame to move from the uppermost position to the lowermost position independent of movement of the position actuator.
