Solution Overview

Problem

Existing vehicle bed extension solutions are complex, occupy existing space when not in use, and are limited in extension capability and load capacity, failing to provide a safe and secure method for transporting large cargo.

Innovation Solution

An integrated extended bed assembly that is slidably fitted into a vehicle bed assembly, extendable rearward by manual manipulation, with sliding members and a support system allowing for multiple position fixation and easy storage, and includes a gate that can be opened to attach a fence for further extension.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If a removable fence structure is attached to the open gate to extend the truck bed, then the cargo space is increased, but the extension is limited to the inner surface of the gate and requires substantial storage space

Engineering Contradiction:

Improvecargo spaceVSAvoidextension structure

Core Design Contradiction:

Volume of moving objectVSDevice complexity

Solution Approach 1:

The bed extension is designed as a dynamic system that can slide between extended and retracted positions along the gate, allowing the cargo space to be adjusted based on need while minimizing storage requirements when not in use

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The bed extension slides within the confines of the gate structure, nesting the extension components within the existing bed assembly when retracted, thereby eliminating the need for separate storage space

Inventive Principle:

Principle #7Nested doll (Nesting)

2Volume of moving object

If a second cargo floor is slidably mounted on top of the existing truck bed flooring, then the cargo space is extended, but the current available space of the truck bed is decreased

Engineering Contradiction:

Improvecargo spaceVSAvoidtruck bed space

Core Design Contradiction:

Volume of moving objectVSArea of stationary object

Solution Approach 1:

Instead of extending the bed floor laterally which would reduce bed width, the extension is achieved by sliding a panel rearward along the gate dimension, utilizing the vertical gate space to provide extension without compromising the main bed area

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Volume of moving object

If multiple sliding elements and actuators are used to extend the second cargo bed, then the extension is achieved, but the structure becomes complex and only two positions are available

Engineering Contradiction:

Improvecargo spaceVSAvoidsliding mechanism

Core Design Contradiction:

Volume of moving objectVSDevice complexity

Solution Approach 1:

The bed extension is divided into multiple panels that can slide independently along the gate, with each panel capable of being positioned separately, providing continuous adjustment rather than fixed positions and simplifying the overall mechanism

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The sliding panels are designed to be manually operable without requiring actuators or complex mechanical systems, allowing the user to extend or retract the bed extension as needed through simple manual manipulation

Inventive Principle:

Principle #25Self-service

AI summary

An integrated extend bed assembly for a vehicle is provided. The extended bed assembly includes a bed assembly that is mounted at a rear of the vehicle and a bed extension that is slidably fitted into the bed assembly. The bed extension is extendable rearward of the bed assembly in a linear motion. Additionally, sliding members are mounted to the bed assembly and the bed extension to support the bed extension in an extended position.
