Hospital Bedside Cabinet Layout for Reversible Drawers and Easy Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bedside cabinets in hospitals face challenges of affordability and cleanliness, particularly due to their symmetrical design which complicates placement and cleaning, and the risk of infection from MRSA, C. difficile, and norovirus outbreaks.
Innovation Solution
A bedside cabinet with a body and drawer that can be inserted and withdrawn from either end, allowing asymmetrical placement and forward-opening configuration for improved accessibility and cleaning, made from synthetic plastics with rounded edges and antimicrobial-free materials to facilitate easy cleaning and patient convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cabinet is designed to be symmetrical for placement on either side of the bed, then the cabinet can be placed on either side of the bed, but the drawer cannot open forwards when placed on the left side and cleaning becomes difficult
Solution Approach 1:
The cabinet body is designed with an asymmetrical structure where the front opening and drawer configuration are specifically oriented. The drawer can only be inserted from and opened towards the front of the cabinet body, creating a unidirectional opening mechanism that ensures consistent drawer access direction regardless of which side of the bed the cabinet is placed on.
Solution Approach 2:
The cabinet body is divided into distinct functional zones: an open front section for drawer access and a closed back section for structural support and cleaning facilitation. The back panel is designed to be removable or openable, allowing easy access for cleaning the interior surfaces without requiring disassembly of the entire cabinet structure.
2Shape
If the cabinet has a closed back for structural completeness, then the cabinet appears complete and symmetrical, but cleaning inside the cabinet becomes difficult
Solution Approach 1:
The back panel of the cabinet is designed as a separate, removable component that can be easily detached from the main cabinet body. This extraction of the back panel allows cleaning personnel to access and clean the interior surfaces of the cabinet without requiring complete disassembly or special tools, while the panel can be reattached to maintain the cabinet's complete appearance when not being cleaned.
3Volume of moving object
If the drawer is made deep for storage capacity, then more items can be stored, but spillage can seep into the drawer and patient access becomes difficult
Solution Approach 1:
The drawer front is designed with a raised lip or barrier that extends above the drawer opening. This preliminary structural feature prevents liquids and spillage from entering the drawer interior, addressing the contamination issue before it can occur. The lip acts as a pre-established barrier that maintains storage capacity while protecting against harmful spillage.
4Strength
If the drawer sides are of full height for structural strength, then the drawer is more durable, but patient access from the bed becomes difficult
Solution Approach 1:
The drawer sides are designed with varying heights: the front portion of the drawer sides is reduced in height to create an open, accessible area that patients can easily reach from the bed, while the rear portion of the drawer sides maintains full height to provide structural strength and support. This local differentiation of side heights allows the drawer to simultaneously achieve patient accessibility and structural durability.

AI summary
A bedside cabinet comprises a body 10 carrying two drawers 12 and 14 all made from synthetic plastics material by rotational moulding. The body 10 comprises a proximal wall 16 and a distal wall 18 each extending upward from a generally horizontal platform 20, and a horizontal top 22 extending between the proximal wall 16 and the distal wall 18. An upstand 28 carries a horizontal shelf 30 extending partly over the top 22 and both the top 22 and the shelf 30 are directed towards the proximal side of the cabinet, having raised lips 32 and 34 respectively around their distal edges and their ends. The cabinet lacks dirt traps and is easily cleaned. In addition the drawers 12 and 14 are reversible so as to open forwards whether the cabinet is on the right-hand side or the left-hand side of a bed.
