Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional public diaper changing tables are often unavailable and unsanitary, leading to a frantic search for a suitable location and potential health risks due to germ exposure.
Innovation Solution
A portable diaper changing table in the form of a backpack with carrying straps, compartments for storage, a pivoting changing surface, safety straps, and an attachment device for secure use, made of rigid elastic material to ensure safety and hygiene.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a portable diaper changing table is carried by the user, then availability and convenience are improved, but weight and portability burden increase
Solution Approach 1:
The changing table is divided into multiple compartments including a first compartment for the changing surface, a second compartment for storage, and a third compartment for waste disposal. This segmentation allows the device to be portable while organizing functions efficiently.
Solution Approach 2:
The patent combines multiple functions into a single portable device: changing surface, storage for diapers and supplies, waste disposal bag, and attachment mechanisms. This merging provides comprehensive functionality in one carryable unit.
2Object-affected harmful factors
If a conventional public diaper changing table is used, then sanitation issues arise, but creating a portable solution increases device complexity
Solution Approach 1:
The patent extracts the changing function from fixed public infrastructure and places it in a portable device that the user controls exclusively. This eliminates exposure to public germs while maintaining the changing function.
Solution Approach 2:
The patent incorporates a disposable waste bag in the third compartment for discarding used diapers. This disposable element simplifies sanitation by allowing single-use disposal without requiring complex cleaning mechanisms.
3Ease of operation
If the changing table is made portable with carrying straps, then mobility is improved, but structural stability may be compromised
Solution Approach 1:
The patent uses an expandable frame structure that transitions from a compact carried state to an expanded stable state during use. The frame includes legs that extend to provide stability when the changing table is deployed.
Solution Approach 2:
The attachment device is pre-configured with adhesive elements or mechanical attachment mechanisms that are activated when the changing table is positioned against a surface. This preliminary preparation ensures stable attachment without requiring complex assembly during use.
4Adaptability or versatility
If compartments are added for storage and waste disposal, then functionality is improved, but device weight and complexity increase
Solution Approach 1:
The second compartment serves multiple functions: storing clean diapers, storing wet bags, and holding other baby supplies. This multi-functionality reduces the need for separate dedicated compartments for each item, optimizing space and weight.
Solution Approach 2:
The waste bag is nested within the third compartment, and the compartment structure itself is designed to nest efficiently when collapsed for carrying. This nesting approach minimizes the overall footprint and weight while maintaining all necessary functions.
