Pivoting Vacuum Pump Mount for Bed Rail Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for negative pressure wound treatment lack a reliable and easy-to-implement mounting mechanism on patient care equipment, such as bed rails, which can lead to operational instability and increased risk of device entanglement with surrounding objects.
Innovation Solution
A device with a dimensionally stable holding part that can pivot between a stowed and use position, featuring a hook-like section for secure attachment to carriers like bed rails, and a design that minimizes protrusion to prevent entanglement, allowing for easy cleaning and attachment of additional carrying means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the device is mounted on a carrier using a protruding holding part, then the device can be securely attached to bed rails or frames, but the protruding structure increases the risk of entanglement with surrounding objects
Solution Approach 1:
The holding part is designed to be pivotable between a protruding position for secure attachment to carriers and a retracted position that minimizes entanglement risk. This dynamic adjustment allows the device to transition between different operational states based on mounting requirements.
Solution Approach 2:
The holding part is divided into a hook-like portion for attachment and a main body portion that can pivot relative to the housing. This segmentation allows the attachment function to be separated from the main device structure, enabling independent movement to reduce entanglement while maintaining secure mounting.
2Ease of operation
If the holding part protrudes from the housing for easy attachment, then mounting on carriers becomes simpler, but the device complexity increases due to the additional pivoting mechanism
Solution Approach 1:
The pivoting holding part provides a simple dynamic mechanism that enables easy attachment and detachment while maintaining relatively simple overall device structure. The pivot connection allows automatic positioning during mounting operations.
3Reliability
If the holding part is made dimensionally stable for secure mounting, then attachment reliability improves, but the risk of entanglement with surrounding objects increases due to rigid protrusion
Solution Approach 1:
The holding part combines dimensional stability for reliable attachment with dynamic pivotability to retract and minimize entanglement risk. The dimensionally stable construction is maintained while adding the capability for positional change.
Solution Approach 2:
The holding part is segmented into an attachment function (hook-like portion) and a positioning function (pivoting capability), allowing the stable mounting structure to be separated from the main housing while maintaining secure attachment.

Implementation Method 1
a device generating negative pressure communicates with the wound or the area around the wound via a suction line. A negative pressure in the wound space can be produced
Implementation Method 2
so that negative pressure communication between the negative pressure generating device, the container and the suction line leading to the body can be produced
