Solution Overview

Problem

Utility vehicles often lack an option for a door with a window, which may be desired by users in certain situations.

Innovation Solution

A detachable window unit is mounted to the door of a utility vehicle, comprising a window and a pipe frame that is fixed to the vehicle's body via a hinge, with pipe ends of the window unit frame being detachably connected to the door pipe frame using a locking device, allowing for easy attachment and removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a door with window is provided as standard equipment, then user preference and versatility are improved, but device complexity and manufacturing cost increase

Engineering Contradiction:

Improvedoor configuration optionsVSAvoiddoor structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The door is divided into separate components: the door body (without window) and the detachable window unit. The window unit includes a window panel and a frame that can be attached to or removed from the door body, allowing users to configure the door with or without a window as needed, thereby reducing overall device complexity while maintaining versatility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The window unit is designed to be dynamically attachable and detachable to the door body through a locking mechanism. This dynamic configuration allows the door structure to change based on user needs, providing adaptability without permanently increasing the complexity of the base door structure.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a detachable window unit is added to the door, then versatility is improved, but device complexity increases

Engineering Contradiction:

Improvewindow configurationVSAvoiddoor assembly

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The window unit is designed as a universal detachable component that can be installed on the door body when needed and removed when not needed. The locking mechanism integrates with the existing door pipe frame structure, allowing the same door assembly to serve multiple configurations (with or without window) without requiring entirely separate door designs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If a locking device is used to fix the window unit, then connection reliability is improved, but device complexity increases

Engineering Contradiction:

Improvewindow unit attachmentVSAvoidlocking mechanism

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The locking mechanism is nested within the existing door pipe frame structure. The window unit pipe frame includes locking components that engage with corresponding features in the door pipe frame, utilizing the existing structural elements rather than adding completely separate locking hardware, thereby improving reliability while minimizing additional complexity.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

The utility vehicle has a door and a window unit detachably mounted to the door. The door includes an inner door panel, an outer door panel, and a door pipe frame supporting the inner door panel and the outer door panel. The window unit includes a window and a window unit pipe frame supporting the window. A plurality of downwardly extending pipe ends of the window unit pipe frame are inserted into a plurality of upwardly open pipe ends of the door pipe frame. The pipe ends of the window unit pipe frame are detachably fixed to the pipe ends of the door pipe frame using a locking device.
