Modular Bed With Integrated Waste Container
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bedridden patients face discomfort and require assistance from caregivers to manage their natural needs, leading to back pain for caregivers due to the need for manual handling and positioning of bedpans.
Innovation Solution
A bed design with independently adjustable base and mattress sections, featuring a container for waste collection and motorized positioning to facilitate comfortable elimination and washing without manual manipulation, allowing for ergonomic support and reduced effort during use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a bedpan is manually placed under a bedridden patient by a caregiver, then the patient can eliminate waste, but the caregiver experiences back pain and requires assistance from multiple people
Solution Approach 1:
The bed enables the patient to perform elimination functions independently through motorized positioning of the seat and backrest, eliminating the need for caregiver manual handling and positioning of bedpans, thus preventing back pain while maintaining ease of operation
Solution Approach 2:
The manual mechanical system of caregiver lifting and positioning is replaced with an automated motorized system that controls seat elevation, backrest angle, and bedpan positioning, substituting human physical effort with mechanical automation
2Adaptability or versatility
If the bed structure is modified to allow independent positioning of base and mattress sections, then patient comfort and independence are improved, but device complexity increases
Solution Approach 1:
The bed is divided into modular sections including an adjustable base, separable mattress parts, and an independently positionable seat section with motorized controls, allowing flexible positioning while maintaining manageable structural complexity through standardized modules
Solution Approach 2:
The bed incorporates motorized mechanisms that dynamically adjust the position of the seat, backrest, and base sections, enabling adaptable positioning for patient comfort while automating the complexity of coordination through electronic control systems
3Ease of operation
If a container is integrated into the bed structure for waste collection, then patient independence is enhanced, but the bed occupies more space
Solution Approach 1:
The waste collection container is nested within the bed frame structure, specifically integrated into the base section, allowing the container to be housed within the existing bed footprint without significantly increasing the overall space occupation while enabling patient-independent waste management

AI summary
The device has a backplate divided into two backplate parts (1, 2), and a mattress divided into two mattress parts (3, 4) independent from each other. A bed base (5) is equipped with lateral crosshead guides (6, 7) permitting to create a space (8) between the independent parts of the backplate and the mattress. The bed base is equipped with transversal crosshead guides (9, 10) on which a container (11) for receiving waste is placed, where the container is made of synthetic material.
