Stroller Handrail with Detachable Dinner Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional strollers with integrated handrails and dinner plates face difficulties in cleaning due to the combined structure, which compromises safety when the integrated unit is removed for maintenance.
Innovation Solution
A stroller design featuring a detachable dinner plate that engages with the handrail in a clamping manner, allowing independent operation and easy removal for cleaning, with a resilient structure and adjustable positioning for enhanced stability and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the handrail and dinner plate are integrated into a single structure, then feeding convenience and safety are achieved, but cleaning difficulty increases and maintenance complexity increases
Solution Approach 1:
The patent divides the integrated handrail-dinner plate structure into separate components: the handrail (2) and the dinner plate (3) are detachable from each other. This segmentation allows the dinner plate to be removed for cleaning while the handrail remains on the frame, resolving the contradiction between maintaining feeding convenience and enabling easy cleaning.
Solution Approach 2:
The dinner plate is extracted as a separate detachable component from the handrail structure. This extraction enables the dinner plate to be removed for cleaning purposes while the handrail remains functional on the frame, solving the cleaning difficulty issue while preserving the feeding convenience function.
2Reliability
If the handrail and dinner plate are integrated, then safety and feeding convenience are provided, but the structure complexity increases
Solution Approach 1:
By segmenting the integrated structure into separate handrail and dinner plate components, the patent reduces structural complexity while maintaining safety through the handrail's independent attachment to the frame. The modular design simplifies the overall structure compared to a permanently integrated unit.
Solution Approach 2:
The handrail serves multiple functions: it provides safety protection when attached to the frame, and it can also serve as a mounting structure for the dinner plate. This multi-functionality reduces the need for separate dedicated structures, thereby reducing overall device complexity.
3Ease of operation
If the integrated handrail and dinner plate are removed for cleaning, then cleaning accessibility is improved, but safety protection is lost
Solution Approach 1:
The patent segments the dinner plate from the handrail, allowing the dinner plate to be detached for cleaning while the handrail remains attached to the frame providing continuous safety protection. This segmentation resolves the contradiction by enabling independent maintenance of the dinner plate without compromising safety.
Solution Approach 2:
The dinner plate is extracted as a detachable component that can be removed for cleaning while the handrail remains in place on the frame. This extraction allows cleaning accessibility without losing safety protection, as the handrail's safety function is independent of the dinner plate attachment.
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
Ensures safety and feeding convenience while simplifying maintenance by allowing the handrail to remain functional without the dinner plate, reducing maintenance costs and complexity.
Implementation Method 1
the engaging component is a resilient structure for clamping the handrail in a tight fit manner

AI summary
A stroller (100) includes a frame (1), a handrail (2) and a dinner plate (3). The handrail (2) is installed on the frame (1) and located in front of the frame (1), and the dinner plate (3) is detachably connected with the handrail (2). With detachable connection of the dinner plate (3) and the handrail (2), the dinner plate (3) and the handrail (2) can work independently or together. When the dinner plate (3) is connected to the handrail (2), the stroller (100) has safety and feeding convenience. When the dinner plate (3) is removed from the handrail (2), the handrail (2) still can work, thus ensuring the safety of the stroller (100). It is convenient to remove the dinner plate (3) for cleaning at any time, thereby reducing difficulty of cleaning the dinner plate (3), and the replaceable dinner plate (3) can reduce maintenance cost. Therefore, the stroller (100) has the advantages of simple structure, and that the handrail (2) and the dinner plate (3) can work independently.
