Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing door jambs with beveled edges create openings that allow pests like insects and rodents to enter structures, and conventional sealing materials like steel wool or plastic foam are unsightly, easily damaged, or ineffective.

Innovation Solution

An adjustable door jamb wrap formed by sliding 'L'-shaped inner and outer brackets that together create a 'C' shape, allowing for secure fitting around the door jamb's bottom edge, using 24 gauge steel or similar materials for durability and pest resistance, with adjustable dimensions to fit various door sizes.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If steel wool or plastic foam is used to plug the opening at the bottom of the door jamb, then pest entry is prevented, but the appearance becomes unsightly and the material is easily damaged or chewed through

Engineering Contradiction:

Improvepest entry preventionVSAvoidmaterial durability

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent replaces traditional short-living sealing materials like steel wool and plastic foam with a durable metal jamb wrap that is designed to last. The wrap is made from materials such as aluminum, stainless steel, or other weather-resistant metals that resist chewing, damage, and degradation over time, eliminating the need for frequent replacement while maintaining aesthetic appearance.

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The jamb wrap employs composite construction combining metal brackets with fastening mechanisms and sealing elements. The wrap may incorporate multiple layers or materials including metal brackets, adhesive components, and sealing strips to provide both structural durability and effective pest blocking while maintaining a clean appearance.

Inventive Principle:

Principle #40Composite materials

2Object-affected harmful factors

If steel wool or plastic foam is used to plug the opening, then pest entry is prevented, but the appearance becomes unsightly

Engineering Contradiction:

Improvepest entry preventionVSAvoidaesthetic appearance

Core Design Contradiction:

Object-affected harmful factorsVSShape

Solution Approach 1:

Inventive Principle:

Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The jamb wrap is designed to be aesthetically pleasing and can be customized in color, finish, or material appearance to match the door and surrounding architecture. The metal surface can be painted, anodized, or finished in various styles to blend seamlessly with the door jamb, eliminating the unsightly appearance of traditional sealing materials.

Inventive Principle:

Principle #32Color changes

3Ease of manufacture

If a fixed-size jamb wrap is used, then installation is simplified, but adaptability to different door sizes is reduced

Engineering Contradiction:

Improveinstallation simplicityVSAvoiddoor size compatibility

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The jamb wrap incorporates adjustable components such as slideable brackets, expandable sections, or flexible mounting mechanisms that allow the wrap to be configured to fit various door jamb widths and heights. This dynamic adjustment capability enables a single wrap design to adapt to multiple door sizes while maintaining secure installation and proper sealing.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The jamb wrap is divided into modular segments or sections that can be adjusted, reconfigured, or extended to accommodate different door sizes. The wrap may include adjustable brackets, telescoping sections, or multiple mounting positions that allow customization for various door dimensions while keeping the overall design simple and easy to install.

Inventive Principle:
