Flexible Bedding Enclosure With Sealed Slit for Bed Bug Containment

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional enclosures such as pillowcases and mattress covers are ineffective in preventing bed bugs from escaping or infesting bedding items, leading to difficult and costly infestation control, as they lack sufficient sealing to prevent the migration of bed bugs between the interior and exterior environments.

Innovation Solution

A flexible sheet material enclosure with a slit-like opening and sliding-type fastener, which creates a sealed interior space to prevent bed bugs from escaping or entering, using a combination of strips to ensure a tight seal, even when the fastener is partially closed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional pillowcases and mattress covers are used, then the bedding items can be easily covered and used, but they are not effective in preventing bed bugs from escaping or entering the bedding items

Engineering Contradiction:

Improveeffectiveness in preventing bed bug migrationVSAvoidstructure of the enclosure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses a flexible sheet material to create an enclosure that can conform to bedding items while providing a sealed barrier. The flexible nature allows the enclosure to be easily applied to various bedding shapes and sizes, while the sealed construction prevents bed bug migration. This resolves the contradiction by providing reliable protection through a simple, adaptable flexible structure rather than a complex rigid system.

Inventive Principle:

Principle #30Flexible shells and thin films

Solution Approach 2:

The enclosure is divided into distinct components: the main body formed from sheet material and the separate sealing mechanism consisting of overlapping edges and fasteners. This segmentation allows each component to perform its specific function - the body provides coverage while the sealed edges provide the barrier - resolving the contradiction between simplicity and effectiveness by making the sealing function a distinct, focused element.

Inventive Principle:

Principle #1Segmentation

2Reliability

If conventional enclosures with interior spaces are used, then items can be stored inside, but the enclosures provide easy routes for bed bugs to travel between the interior and exterior environments

Engineering Contradiction:

Improvesealing effectivenessVSAvoidaccess to interior space

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The enclosure incorporates a dynamic opening mechanism that transitions between open and sealed states. The opening can be accessed when needed for inserting or removing bedding items, then closed and sealed to prevent bed bug migration. This dynamic capability resolves the contradiction by providing both ease of access and reliable sealing at different operational stages.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent introduces an intermediary sealing mechanism (overlapping edges with fasteners) that mediates between the interior and exterior environments. This intermediary element allows controlled access while maintaining the barrier function when closed, resolving the contradiction by providing a transition zone that can switch between open and sealed states.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If bed bug infestations are controlled using conventional insecticides, then bed bugs can be killed, but the insecticides have been banned or replaced with weaker alternatives to which bed bugs have developed resistance

Engineering Contradiction:

Improveeffectiveness against bed bugsVSAvoiduse of banned insecticides

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the bed bugs from their environment by enclosing infested bedding items in a sealed barrier. This physical containment removes the bed bugs from contact with humans and prevents their migration to new locations, eliminating the need for chemical insecticides. This resolves the contradiction by providing effective bed bug control through physical isolation rather than chemical elimination.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent converts the problem of bed bug infestation into a beneficial containment solution. By sealing the bedding items, the enclosure transforms the harmful presence of bed bugs into a controlled situation where they are isolated and cannot cause harm or spread. This resolves the contradiction by turning the infestation problem into a manageable containment scenario without using banned chemicals.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

An enclosure for preventing certain organisms from escaping from an item susceptible to infestation into the surrounded environment and for preventing certain organisms from entering the item susceptible to infestation from the surrounding environment. The enclosure is defined by a flexible sheet material defining an interior space. The enclosure comprises a slit-like opening formed in the flexible sheet material through which an item susceptible to infestation can be inserted into the interior space defined by the enclosure.
