Solution Overview

Problem

Existing patient support apparatuses face issues with control boxes for limb compression sleeves slipping off footboards, creating tripping hazards and requiring long power cords, which increase labor and costs while reducing caregiver efficiency and patient comfort.

Innovation Solution

Integrating a storage pocket, drawer, or conduit system within the footboard of patient support apparatuses to house and manage pneumatic therapy devices, eliminating the need for separate control boxes and reducing clutter, and incorporating a main controller to manage pneumatic therapy operations efficiently.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a separate control box is provided for the compression sleeves, then the pneumatic components can be housed separately, but the control box may slip off the footboard and create tripping hazards

Engineering Contradiction:
Improveseparate control boxVSAvoidcontrol box stability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent integrates the control box into the footboard structure itself, merging two previously separate components (control box and footboard) into a single unified structure. This eliminates the risk of the control box slipping off while maintaining all necessary pneumatic functions for compression sleeve operation.

Inventive Principle:
Principle #5Merging (Combining)

2Device complexity

If a separate control box is used, then pneumatic components can be housed separately, but long power cords are required creating tripping hazards

Engineering Contradiction:
Improveseparate control boxVSAvoidtripping hazard
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

By integrating the control box into the footboard, the patent eliminates the need for long power cords that would extend across the room to reach outlets. The power connection can be made locally at the footboard, removing the tripping hazard while maintaining separate component housing.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If the control box is hung on the footboard, then it is accessible, but it requires separate storage when not in use

Engineering Contradiction:
ImproveaccessibilityVSAvoidseparate storage requirement
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The integration of the control box into the footboard structure means the device is permanently housed where it is needed, eliminating the requirement for separate storage solutions. The footboard itself becomes both the mounting structure and the housing, reducing overall system complexity.

Inventive Principle:
Principle #5Merging (Combining)

4Object-affected harmful factors

If integrated storage or conduit systems are added to the footboard, then clutter is reduced and safety improved, but device complexity increases

Engineering Contradiction:
Improveclutter and tripping hazardsVSAvoidfootboard integration
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent merges multiple functions (control box housing, power distribution, conduit routing, and storage) into the footboard structure itself. While this increases the footboard's functional complexity, it consolidates multiple separate components into one integrated unit, ultimately reducing overall system complexity and eliminating clutter.

Inventive Principle:
Principle #5Merging (Combining)
