Solution Overview

Problem

Window systems for construction vehicles often have an all-or-nothing approach, limiting user options during inclement weather.

Innovation Solution

A window assembly with multiple movable panes and track assemblies that allow for various open configurations, including fixed and movable panes, and latch assemblies with tongue members that move between extended and retracted positions to secure the panes in different positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a window system uses an all-or-nothing approach with single movable pane, then the structure is simple and easy to manufacture, but the adaptability and user options are limited

Engineering Contradiction:

Improvewindow opening configurationsVSAvoidwindow assembly structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The window assembly is divided into multiple independent movable panes (first movable pane and second movable pane) that can operate separately. Each pane has its own track assembly and latch assembly, allowing independent control of each pane's position and opening state, thereby providing multiple configuration options without requiring a completely complex redesign

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The track assembly is designed with multiple notches that can accommodate different latch positions, allowing the same track structure to support various opening configurations (first partially open position, second partially open position, fully open position). This multi-functional design enables a single structure to provide multiple window opening states

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple movable panes with multiple positions are added, then the adaptability and venting options are improved, but the device complexity and number of components increase

Engineering Contradiction:

Improveventing optionsVSAvoidnumber of latch assemblies and track assemblies

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The window system is segmented into multiple movable panes (first movable pane and second movable pane), each with independent control mechanisms. This segmentation allows different portions of the window to be opened independently, creating multiple venting configurations without requiring a single complex mechanism

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The latch assemblies are designed to be movable between extended and retracted positions, allowing dynamic adjustment of pane positions. The track assemblies include multiple notches that accommodate different latch positions, enabling the system to dynamically transition between various opening states (partially open, fully open, closed) based on user needs

Inventive Principle:

Principle #15Dynamics

AI summary

An example window assembly includes a fixed pane, a first movable pane movable between a closed position and an open position, and a second movable pane movable between a closed position and a first partially open position where at least a portion of the second movable pane is disposed over the fixed pane, between the closed position and a second partially open position where at least a portion of the second movable pane is disposed over the first movable pane, and between the closed position and the open position.
