Removable Lumbar Section for Bedridden Patient Care
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hospital beds for bedridden persons lack features that facilitate tasks such as washing, cleaning, and changing diapers, which can be painful for individuals with mobility issues and strenuous for caregivers, while also causing undesirable movements that increase pain.
Innovation Solution
A bed with independent sections and a removable lumbar section equipped with fixed supports and a waterproof sheet system, allowing caregivers to perform tasks without moving the patient, reducing pain and workload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the head section is adjusted in conventional hospital beds, then the bedridden person's comfort is improved, but the occupant is pushed forward which increases pain and makes it difficult to perform care tasks
Solution Approach 1:
The bed is divided into multiple independent sections (head section, lumbar section, leg section) that can be adjusted separately. The lumbar section is further segmented into a removable part and a fixed support structure, allowing care tasks to be performed without moving the occupant while maintaining comfort in other sections.
Solution Approach 2:
The lumbar section is extracted as a removable component from the bed structure. This allows the lumbar mattress to be removed and placed aside while the fixed supports remain in place to continue supporting the occupant, enabling care tasks to be performed without disturbing the occupant's position or causing pain.
2Productivity
If conventional hospital beds are used for washing and cleaning, then care tasks can be performed, but the bedridden person must be moved or turned which causes pain and increases caregiver workload
Solution Approach 1:
The lumbar section is extracted as a removable component that can be taken out to the side of the bed. This creates direct access to the occupant's lumbar area for washing and cleaning tasks without requiring the occupant to be moved or turned, significantly reducing pain and caregiver workload.
Solution Approach 2:
The fixed supports act as an intermediary structure that maintains support for the occupant while the removable lumbar section is taken away. This allows care tasks to be performed on the occupant's body directly without needing to move them, as the fixed supports continue to provide necessary support.
3Stability of the object's composition
If the lumbar section is made fixed in conventional beds, then structural stability is improved, but access for care tasks such as washing and changing diapers is restricted
Solution Approach 1:
The lumbar section is segmented into two parts: a removable lumbar mattress and fixed supports. The fixed supports provide structural stability and remain in place, while the removable mattress can be taken away to provide access for care tasks. This segmentation allows the bed to maintain stability while being adaptable for various care needs.
Solution Approach 2:
The lumbar section transitions from a static fixed structure to a dynamic system where the mattress can be removed and repositioned. The fixed supports remain stationary to maintain stability, while the removable mattress can be dynamically adjusted or removed to provide access when needed, making the bed adaptable to different care requirements.
