Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Caregivers face unsafe situations when changing a baby at night in a dark room, as turning on bright lights can startle the baby or require them to divert attention from the baby, compromising safety and comfort.

Innovation Solution

A baby changing pad with a built-in, portable battery-powered low-intensity illumination system that provides sufficient light for diaper changing without needing to turn on room lights, using various lighting elements such as electroluminescent wires, flexible panels, LEDs, or phosphorescent glow paint, strategically positioned to illuminate the baby and the changing area.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If bright room lights are turned on to enable the caregiver to see while changing the baby, then the illumination intensity is improved, but the baby may be startled or awakened and the caregiver must divert attention from the baby

Engineering Contradiction:

Improveillumination intensityVSAvoidbaby disturbance

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by providing illumination only in the specific area where the baby is lying on the changing pad, rather than illuminating the entire room. The lighting element is positioned to cast light locally on the baby and immediate surrounding area, enabling the caregiver to see while maintaining darkness in the rest of the room, thus avoiding baby disturbance.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The patent segments the illumination function by separating the lighting element from the changing pad structure and positioning it strategically to provide focused lighting. The lighting system is divided into discrete components (lighting element, power device) that can be independently controlled to provide illumination only when and where needed, rather than requiring full room lighting.

Inventive Principle:

Principle #1Segmentation

2Illumination intensity

If the caregiver takes a hand away from the baby to turn on room lights, then the illumination is improved, but the safety of the baby is compromised

Engineering Contradiction:

Improveillumination intensityVSAvoidsafety

Core Design Contradiction:

Illumination intensityVSReliability

Solution Approach 1:

The patent merges the lighting function with the changing pad by integrating the lighting element and power device directly into the pad structure. This combination allows the caregiver to activate illumination without leaving the baby, as the light can be turned on while maintaining physical contact and attention on the baby, thereby preserving safety while providing necessary visibility.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The changing pad provides self-service illumination by incorporating its own lighting element and power device, eliminating the need for the caregiver to manually operate external room lights. The pad can be activated to provide light independently, allowing the caregiver to maintain focus on the baby without interruption.

Inventive Principle:

Principle #25Self-service

3Object-affected harmful factors

If portable battery-powered lighting is built into the changing pad, then the baby disturbance is reduced, but the device complexity increases

Engineering Contradiction:

Improvebaby disturbanceVSAvoiddevice complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent applies universality by designing the changing pad to serve multiple functions: it provides both the changing surface and integrated lighting capabilities. The power device can draw energy from battery sources, making the system versatile and adaptable to different power availability scenarios, while maintaining a relatively simple overall structure that combines these functions in a unified device.

Inventive Principle:

Principle #6Universality (Multi-functionality)
