Solution Overview

Problem

Conventional fixed underrides are incompatible with lift gates, as they interfere with the stowing and unstowing of the lift, and cannot be adjusted to accommodate different vehicle bed heights or dock lock configurations.

Innovation Solution

A moveable underride system with a mounting mechanism featuring clamping jaws and adjustable brackets that allow for remounting on a vehicle frame, enabling the underride to be extended and retracted without interfering with the lift gate's operation, and accommodating various vehicle bed heights and dock lock positions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a fixed underride is installed on the vehicle, then the underride provides protection against following vehicles, but the underride interferes with the stowing and unstowing of the lift gate

Engineering Contradiction:
Improveprotection against following vehiclesVSAvoidstowing and unstowing of lift gate
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The underride is designed to be movable rather than fixed, allowing it to change position relative to the vehicle bed. The mounting mechanism includes movable mounting members that enable the underride to move between a first position (when lift gate is stowed) and a second position (when lift gate is unstowed), eliminating interference while maintaining protection functionality

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mounting system is divided into separate movable mounting members that independently control the underride's position. This segmentation allows the underride to be mounted and dismounted separately, enabling it to adapt its position based on lift gate operation requirements

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If a fixed underride is installed on the vehicle, then the underride provides structural stability, but the underride cannot be adjusted to accommodate different vehicle bed heights or dock lock configurations

Engineering Contradiction:
Improvestructural stability of underrideVSAvoidadjustment to different vehicle bed heights
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The underride mounting system uses movable mounting members that can adjust their position to accommodate different vehicle bed heights and dock lock configurations. The underride can be mounted at various positions along the vehicle bed, providing both structural stability when mounted and adaptability to different configurations

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mounting mechanism is designed with universal adaptability to work with different vehicle types, bed heights, and dock lock configurations. The movable mounting members can be positioned to accommodate various geometries, making the underride system universally applicable across different vehicle configurations

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A mounting mechanism for mounting an underride system on a structure, comprises a pair of clamping jaws, and a first bracket including a first edge for coupling the underride system thereto. The first bracket further includes a second edge for coupling the pair of clamping jaws thereto. Wherein, the first bracket and the pair of clamping jaws define a jaw opening therebetween configured to receive at least a portion of the structure for removably mounting the underride system on the structure using the mounting mechanism.
