Solution Overview

Problem

Existing patient restraint systems for hospital beds lack efficient and easy methods for secure attachment and detachment, leading to potential instability and difficulty in relocating or cleaning.

Innovation Solution

A restraint anchor with a strap system featuring a looped first section and a second section that can be secured through a buckle, utilizing stops to prevent backward movement, allowing quick and secure attachment to hospital bed components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a traditional restraint attachment method is used, then the restraint can be secured to the patient support apparatus, but the attachment and detachment processes are difficult and time-consuming

Engineering Contradiction:

Improveease of attachment and detachmentVSAvoidtime required for attachment and detachment

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The restraint system is divided into separate components: a restraint anchor with a strap forming a loop, and a buckle component. This segmentation allows the second strap section to be independently threaded through the loop and secured with the buckle, enabling quick attachment and detachment without requiring complex manipulation of a single integrated component.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first strap section is pre-formed into a loop configuration before use. This preliminary shaping allows the second strap section to be easily threaded through during attachment, and the loop to be quickly secured with the buckle component, significantly reducing the time required for attachment compared to forming the loop during the attachment process itself.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If a simple strap loop is used for attachment, then the structure is simple, but the restraint may accidentally detach from the component

Engineering Contradiction:

Improvesecurity of restraint attachmentVSAvoidcomplexity of strap structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The strap system incorporates a dynamic locking mechanism where the second strap section can be threaded through the loop and secured in place by the buckle component. This dynamic design allows the restraint to transition from an unsecured state to a locked state, preventing accidental detachment while maintaining operational simplicity through the intuitive buckle fastening action.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The buckle component serves as an intermediary element between the strap loop and the restraint anchor. It provides a reliable mechanical connection that secures the second strap section through the loop, preventing accidental detachment without requiring complex strap configurations. The buckle acts as a mediator that simplifies the overall structure while enhancing security.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Strength

If the strap is made wide for secure attachment, then the attachment strength is improved, but the strap becomes difficult to insert through narrow spaces

Engineering Contradiction:

Improveattachment strength of strapVSAvoidease of insertion through narrow spaces

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The strap is segmented into a first strap section and a second strap section. The first strap section maintains a wider configuration for secure attachment to the component, while the second strap section can be independently manipulated and threaded through narrow spaces. This segmentation allows different portions of the strap to have different effective widths, solving the contradiction between attachment strength and insertion ease.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The strap configuration transitions from a wide two-dimensional structure in the first section to a more compact arrangement in the second section. By changing the dimensional configuration of the strap along its length, the design maintains adequate width for secure attachment while allowing the second section to be folded or manipulated into a compact form for insertion through narrow spaces.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

A restraint anchor for a component of a patient support apparatus includes a strap having first and second strap sections. The first strap section has opposed first and second distal ends and forms a loop between the first and second distal ends, with the first strap section for looping around the component of the patient support apparatus and for receiving the second strap section through the loop for securing the anchor to the component. The second strap section has first and second ends, with the first end of the second strap section coupled to the first and second distal ends of the first strap section, and the second end of the second strap section coupled to a buckle component. The strap further has at least one stop to limit movement of the second strap section through the loop wherein the stop helps retain the anchor on the component.
