Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing vehicle extensions do not allow for the installation of full-sized OEM windows, limiting interior cubic volume and customization options, as they have a smaller window mount surface area than the original vehicle window opening.

Innovation Solution

A vehicle wall extension that uses OEM windows, featuring a flange protruding around the perimeter for increased surface area contact, a ridge to prevent water leakage and reduce drag, and a slope to manage drag forces, allowing full-sized OEM windows to be installed and increasing interior space without requiring significant structural modifications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If existing vehicle extensions are designed to fit inside original window openings to ease installation, then installation complexity is reduced, but the window mount surface area becomes smaller than the original vehicle window opening, preventing installation of full-sized OEM windows

Engineering Contradiction:

Improveinstallation easeVSAvoidwindow mount surface area

Core Design Contradiction:

Ease of manufactureVSArea of stationary object

Solution Approach 1:

The extension transitions from fitting inside the window opening (2D plane) to protruding outward in three-dimensional space. This dimensional change allows the extension to provide a full-sized mounting surface for OEM windows while maintaining compatibility with the original window opening dimensions, effectively resolving the contradiction between installation ease and mounting surface area.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Volume of stationary object

If the extension protrudes from the vehicle wall to increase interior volume, then interior cubic volume increases, but drag forces may cause damage to the extension

Engineering Contradiction:

Improveinterior cubic volumeVSAvoiddrag force damage

Core Design Contradiction:

Volume of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The extension incorporates a curved or aerodynamic profile rather than a sharp protrusion. This curvature reduces drag forces by allowing air to flow smoothly around the extension, preventing damage while still providing the desired interior volume increase. The curved design effectively mitigates the harmful drag forces that would otherwise affect a protruding structure.

Inventive Principle:

Principle #14Spheroidality (Curvature)

3Ease of manufacture

If the extension uses a smaller window mount surface area, then installation avoids vehicle structure modifications, but customization options and interior volume are limited

Engineering Contradiction:

Improvestructural modification avoidanceVSAvoidcustomization options

Core Design Contradiction:

Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The extension is designed as a separate, modular component that can be installed without modifying the original vehicle structure. This segmentation allows the extension to provide full-sized OEM window mounting capabilities and customization options while leaving the original vehicle intact, effectively resolving the contradiction between avoiding structural modifications and maintaining adaptability.

Inventive Principle:

Principle #1Segmentation
