Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing hinge connections in vehicles, particularly in pickup trucks, struggle to effectively manage lateral forces from heavy tailgates, especially in aluminum bed constructions which are less stiff than steel, necessitating a reinforcement system to enhance structural integrity.

Innovation Solution

A hinge connection system incorporating a reinforcement plate with an extension portion and a gusset that transfers lateral loads to a rear cross member, combined with a dual action strut for additional support, utilizing aluminum or steel stampings or castings for the gusset and reinforcement components.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If aluminum bed construction is used, then weight is reduced, but structural stiffness and strength decrease

Engineering Contradiction:

Improvevehicle bed weightVSAvoidbed structure strength

Core Design Contradiction:

Weight of moving objectVSStrength

Solution Approach 1:

The patent employs a hybrid construction approach where aluminum bed components are reinforced with steel or aluminum gussets and cross members. The gusset (254) is selectively positioned at high-stress hinge connection points to provide localized strength enhancement while maintaining overall aluminum construction for weight reduction.

Inventive Principle:

Principle #40Composite materials

2Quantity of substance

If tailgate weight is increased, then cargo capacity is improved, but hinge connection stress increases

Engineering Contradiction:

Improvecargo capacityVSAvoidhinge connection stress

Core Design Contradiction:

Quantity of substanceVSStress or pressure

Solution Approach 1:

The gusset (254) extends in multiple dimensions from the hinge connection point, creating a three-dimensional reinforcement structure that distributes loads across additional spatial dimensions. This multi-directional extension provides structural support that counteracts the increased stress from heavier tailgates.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The gusset acts as an intermediary structural element between the hinge bracket and the bed cross member, transferring and distributing the lateral forces generated by heavy tailgates across a broader area of the bed structure, thereby reducing concentrated stress at the hinge connection point.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Strength

If reinforcement components are added, then structural integrity is improved, but device complexity increases

Engineering Contradiction:

Improvehinge connection strengthVSAvoidconnection system complexity

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The gusset is designed to be integrally formed with or directly attached to the existing bed cross member, merging the reinforcement function with the structural support function of the cross member. This integration approach adds strength while minimizing the increase in component count and system complexity.

Inventive Principle:

Principle #5Merging (Combining)
