Solution Overview

Problem

Existing diaper changing stations often tip over when placed on narrow furniture surfaces due to their size mismatch, making it difficult to position them optimally for diaper changing and posing safety risks.

Innovation Solution

A rotatable diaper changing table system with a base, pad, and stabilizing brace that allows for adjustable positioning and secure attachment to walls or furniture, featuring compartments for supplies and a swivel mechanism to prevent tipping.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the diaper changing station is placed in a frontal position to improve accessibility, then ease of operation is improved, but stability deteriorates because the length of the pad exceeds the width of the countertop causing it to hang over the edge

Engineering Contradiction:
Improveaccessibility to babyVSAvoidstability of changing station
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent introduces a rotational dimension by providing a stabilizing brace with a rotatable connector that allows the changing station to pivot between frontal and sideways orientations. This enables the station to achieve optimal positioning in either dimension while maintaining stability through the wall-mounted brace support.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Stability of the object's composition

If the diaper changing station is positioned to maximize interface area with furniture to improve stability, then stability is improved, but ease of operation deteriorates because the sideways orientation makes it more difficult to reach the baby

Engineering Contradiction:
Improvestability of changing stationVSAvoidaccessibility to baby
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The patent transforms the static changing station into a dynamic system by incorporating a rotatable connector in the stabilizing brace. This allows the station to be rotated from a sideways stable position to a frontal accessible position, and vice versa, enabling adaptive positioning based on operational needs while maintaining stability throughout the range of motion.

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If a traditional fixed changing station is used on narrow furniture, then device complexity is minimized, but adaptability deteriorates because it cannot be optimally positioned when not in use or on furniture of varying widths

Engineering Contradiction:
Improvepositioning flexibilityVSAvoidcomplexity of mounting system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent divides the mounting system into separate functional components: a stabilizing brace for wall mounting, a rotatable connector for positioning adjustment, and the changing station itself. This segmentation allows each component to perform its specific function independently, providing adaptability while keeping the overall system manageable in complexity.

Inventive Principle:
Principle #1Segmentation
