Solution Overview
Problem
Existing diaper-changing tables often lead to accidents due to falls, as they either compromise comfort or do not adequately prevent falls, especially during critical periods when infants begin to move, and existing safety solutions are cumbersome or ineffective.
Innovation Solution
A diaper-changing shelf with a movable barrier that automatically detects the presence of a caregiver, opening to allow safe access and closing when the caregiver is not present to prevent falls, using a detection device that does not require active operation by the caregiver.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a belt solution is used to prevent falls, then fall prevention is improved, but comfort during nappy changing deteriorates
Solution Approach 1:
The barrier is designed to be movable rather than fixed, allowing it to dynamically change position between a closed safety state and an open access state. This resolves the contradiction by providing fall prevention when needed while allowing comfortable access when the caregiver is present
Solution Approach 2:
The system automatically detects the caregiver's presence and autonomously opens the barrier without requiring manual operation. This eliminates the need for the caregiver to manually adjust the barrier, maintaining both safety and comfort during nappy changing
2Reliability
If barriers are made high to prevent falls, then fall prevention is improved, but ease of placing and removing the baby deteriorates
Solution Approach 1:
The barrier height is dynamically adjustable between a high closed position for fall prevention and a low open position for easy baby placement and removal. This resolves the contradiction by providing both high safety when needed and easy access when the caregiver is present
3Reliability
If a movable barrier with manual activation is used, then fall prevention is improved, but device complexity and distraction to caregiver increases
Solution Approach 1:
The system uses an automatic detection device to sense the caregiver's presence and autonomously control the barrier position. This eliminates the need for manual activation mechanisms like pedals or push buttons, reducing device complexity and avoiding distraction to the caregiver while maintaining fall prevention
Solution Approach 2:
The manual mechanical activation system is replaced with an automatic detection system that uses sensors to detect the caregiver's presence and automatically actuates the barrier. This substitution reduces operational complexity while maintaining safety functionality

AI summary
The present invention concerns shelves (10, 20, 30, 40, 50) for changing the diaper of an infant or toddler. A shelf comprises a movable barrier (13) and a facility (18, 53) for automatically detecting a caregiver. The facility for automatically detecting is adapted to bring the movable barrier into an open state when the facility for automatically detecting detects a caregiver.
