Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing infant accommodation apparatus, particularly inflatable annular bodies, face issues such as high production costs due to large plastic material usage, lengthy inflation times, inadequate lateral support, and weak frame structures that can collapse, along with limited stimulation options.
Innovation Solution
The design features a resilient and inflatable inner enclosure wall with a modified triangular shape, a flexible fabric cover, and a self-supporting frame that allows for easy assembly and inflation, providing lateral support and multiple stimulation options while using less plastic material and allowing for adjustable volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a large volume inflatable annular body is used, then the infant accommodation space is sufficient, but the production cost increases due to large plastic material usage
Solution Approach 1:
The patent employs a thin-film inflatable membrane structure that provides sufficient accommodation volume while minimizing material consumption. The flexible shell design allows the structure to achieve its functional volume when inflated, rather than requiring thick-walled rigid construction, thereby reducing plastic material usage while maintaining adequate space for the infant.
Solution Approach 2:
The inflatable annular body transitions from a compact deflated state to an expanded inflated state, dynamically adjusting its volume to provide sufficient accommodation space only when needed. This dynamic transformation allows the structure to achieve large volume during use while occupying minimal space during storage and transport, reducing the average material requirement.
2Volume of moving object
If a large volume inflatable annular body is used, then the infant accommodation space is sufficient, but the inflation time increases particularly if manually inflated
Solution Approach 1:
The inflatable structure is divided into multiple chambers or sections that can be inflated independently or in sequence. This segmentation reduces the total inflation time by allowing parallel inflation processes and reducing the distance air must travel through the structure, while still achieving the required total accommodation volume.
Solution Approach 2:
The patent utilizes pneumatic principles with strategically placed inflation valves and air channels that optimize airflow distribution throughout the inflatable structure. This pneumatic design enables faster and more uniform inflation compared to simple single-chamber designs, reducing the time required to achieve full accommodation volume.
3Ease of manufacture
If a simple annular body is used, then the production is simple, but the lateral support for the infant is insufficient
Solution Approach 1:
The inflatable annular body incorporates asymmetric internal reinforcement elements or non-uniform wall thickness distribution, with thicker or reinforced sections positioned at locations requiring greater lateral support for the infant. This asymmetric design provides enhanced strength where needed while maintaining simple overall geometry and manufacturability.
Solution Approach 2:
The patent employs composite construction combining a thin flexible inflatable membrane with embedded reinforcement elements such as rigid ribs, fabric layers, or structural beads. This composite approach provides the necessary lateral support strength while keeping the base structure simple and easy to manufacture, as the reinforcement elements can be integrated into the molding or assembly process.
4Adaptability or versatility
If a frame means is added for stimulation, then the stimulation options are provided, but the assembly difficulty increases and the structure becomes weaker
Solution Approach 1:
The stimulation elements are extracted from the main inflatable structure and provided as separate, removable attachments. This allows the stimulation components to be added or removed independently without affecting the core inflatable accommodation, simplifying assembly and reducing overall structural complexity while maintaining versatility.
Solution Approach 2:
The frame means is designed with universal attachment points and standardized interfaces that can accommodate various stimulation elements. This multi-functional design allows a single simple frame structure to support multiple different stimulation options, increasing adaptability without proportionally increasing assembly difficulty or structural complexity.

AI summary
An infant accommodation apparatus (2) comprises an inflatable support (4) and a framework (6) which abuts and extends over the device and includes toys arranged to stimulate an infant accommodated within an accommodation region (7) of the device. The support device has respective parallel inner and outer walls (13, 14) in the shape of modified equilateral triangles. Thus, the outer wall (14) of the member (8) may be regarded as being of a modified triangular shape having three curved apex regions (20) each of which has a radius of curvature which is less than the radius of curvature of the outer wall at positions between the apex region (20).
