Solution Overview

Problem

Underpads on mattresses tend to slip, slide, or bunch, causing discomfort and making it difficult to maintain coverage and protection, especially for patients with incontinence or involuntary bowel movements, which can lead to soiling of the mattress.

Innovation Solution

A securing assembly with securing members on the underpad and mating securing members on the mattress, such as VELCRO®, hooks, or snap buttons, that removably engage to immovably secure the underpad in place, using belts and adjustable mechanisms to accommodate various mattress sizes and prevent movement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an underpad is positioned on a mattress to absorb urine and prevent leakage, then protection against soiling is improved, but the underpad slips, slides, and bunches causing discomfort and requiring repositioning

Engineering Contradiction:
Improveprotection against soilingVSAvoidposition stability of underpad
Core Design Contradiction:
ReliabilityVSStability of the object's composition

Solution Approach 1:

The underpad is divided into multiple sections with independent securing mechanisms. Multiple securing members are distributed across the underpad surface, allowing each section to be independently stabilized, preventing overall slippage and bunching while maintaining absorption effectiveness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Securing members are pre-positioned on the underpad before use, and mating securing members are pre-positioned on the mattress or bed sheet. This preliminary arrangement ensures that when the underpad is placed, it immediately engages the securing mechanisms, preventing initial slippage and establishing stable positioning from the start.

Inventive Principle:
Principle #10Preliminary action

2Stability of the object's composition

If the underpad is secured firmly to prevent movement, then position stability is improved, but ease of removal and replacement deteriorates

Engineering Contradiction:
Improveposition stability of underpadVSAvoidease of removal and replacement
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The securing mechanism uses dynamic fastening elements such as snap buttons or hook-and-loop fasteners that provide strong engagement during use but allow quick release when needed. This dynamic characteristic enables the underpad to remain firmly secured during patient use while facilitating easy removal and replacement when soiled.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The securing members and mating securing members are designed to be temporarily engaged during use and then easily disengaged for replacement. The securing mechanism allows the underpad to be quickly removed and replaced with a fresh one, maintaining hygiene while minimizing disruption to the patient.

Inventive Principle:
Principle #34Discarding and recovering

3Stability of the object's composition

If securing members are added to the underpad to prevent slippage, then position stability is improved, but device complexity increases

Engineering Contradiction:
Improveposition stability of underpadVSAvoidcomplexity of securing assembly
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The securing members are integrated directly into the underpad construction, and mating securing members are integrated into the mattress or bed sheet. This merging of functions eliminates the need for separate, complex securing devices, as the stabilization function is combined with the existing underpad and mattress components.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The securing mechanism is designed to be self-aligning and self-securing. The securing members on the underpad automatically engage with the mating securing members on the mattress or bed sheet when the underpad is placed, without requiring manual adjustment or complex activation mechanisms, thereby simplifying the overall device.

Inventive Principle:
Principle #25Self-service

AI summary

An apparatus comprises a mattress. An underpad is positioned on the mattress such that a lower surface of the underpad is in contact with the mattress. A securing assembly is interposed between the mattress and the underpad. The securing assembly comprises a plurality of securing member positioned on the lower surface of the underpad, and a plurality of mating securing members positioned on the mattress. Each of the plurality of securing members engages a corresponding mating securing member so as to be removably coupled thereto, thereby immovably positioning the underpad on the mattress.
