Current methods for mounting medical equipment to IV poles are cumbersome, require complex and costly hardware, leading to user fatigue and insufficient clamping force, which can result in patient injury or equipment damage due to the need for manual tightening using mechanical parts like lead screws and knobs.

Innovation Solution

A clamp device utilizing a gravity-assisted wedging action with a base and slider configuration, featuring angled coupling elements and troughs to securely mount equipment to a support structure, allowing for easy installation and removal without relying on user strength for tightening, accommodating a range of support structure diameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Force

If traditional lead screw and knob mounting mechanisms are used, then clamping force can be generated, but the device complexity increases and ease of operation deteriorates due to multiple mechanical parts and special tools required

Engineering Contradiction:
Improveclamping forceVSAvoidhardware complexity
Core Design Contradiction:
ForceVSDevice complexity

Solution Approach 1:

The mounting mechanism is divided into two main segments: a stationary base and a movable slider. The base contains coupling elements that engage with corresponding coupling elements in the slider, allowing the slider to slide along the base while maintaining a secure connection. This segmentation simplifies the overall structure by eliminating complex lead screws and knobs while still providing effective clamping force through the sliding engagement of the segmented components.

Inventive Principle:
Principle #1Segmentation

2Force

If traditional lead screw mechanisms are used, then clamping force can be applied, but ease of operation worsens due to the need for multiple wrist rotations leading to user fatigue

Engineering Contradiction:
Improveclamping forceVSAvoidease of tightening
Core Design Contradiction:
ForceVSEase of operation

Solution Approach 1:

The slider mechanism utilizes the weight of the medical equipment itself to generate and maintain clamping force. As the equipment is mounted on the slider, its weight automatically urges the slider against the base, creating the necessary clamping force without requiring additional manual tightening efforts from the user. This self-service approach eliminates the need for repeated wrist rotations and special tools.

Inventive Principle:
Principle #25Self-service

3Force

If multiple rotations of the knob are required to achieve sufficient tightening, then clamping force can be increased, but loss of time increases and productivity decreases

Engineering Contradiction:
Improveclamping forceVSAvoidmounting time
Core Design Contradiction:
ForceVSLoss of time

Solution Approach 1:

The base is pre-configured with coupling elements positioned and oriented to automatically engage with corresponding coupling elements in the slider. This preliminary arrangement of coupling elements ensures that when the slider is positioned on the base, the engagement occurs immediately without requiring multiple rotational adjustments or time-consuming tightening operations. The clamping force is established through the predetermined geometric relationship between the coupling elements.

Inventive Principle:
Principle #10Preliminary action

4Force

If traditional mounting hardware is used, then clamping force can be generated, but manufacturing cost increases due to costly materials and complex assembly

Engineering Contradiction:
Improveclamping forceVSAvoidmanufacturing cost
Core Design Contradiction:
ForceVSEase of manufacture

Solution Approach 1:

The coupling elements are integrated directly into the base and slider structures, merging the clamping function with the mounting structure itself. This integration eliminates the need for separate, costly lead screw mechanisms and specialized hardware components. The coupling elements are formed as part of the base and slider bodies, simplifying manufacturing processes and reducing material costs while maintaining the necessary clamping force capability.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A clamp device (100) for mounting equipment to a support structure (200) including a base (105) and a slider (110). The base (105) includes a first trough (155) formed in the front side (140) of the base (105) and a second trough (160) formed in the back side (145) of the base (105) and a first coupling element located on the first lateral side (130) and a second coupling element located on the second lateral side (135) of the base (105). Each of the first and second coupling elements extend from near the top end (120) of the base (105) towards the bottom end (125) of the base (105) at an angle relative to the first trough (155). The slider (110) includes a channel (185) on a back side (145) of the slider (110) and corresponding coupling elements within the channel (185) configured to slidingly engage the first and second coupling elements upon association of the slider (110) with the base (105).
