Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Older pickup trucks lack a convenient and aesthetically pleasing mechanism for opening and closing tailgates, relying on chains and hooks, making them difficult to operate compared to modern trucks.

Innovation Solution

A tailgate latch system featuring a rotary latch and rotatable rod mechanism that allows for easy engagement and disengagement of the tailgate with striker pins, along with a tilting truck bed design that enhances accessibility and functionality.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a chain and hook system is used to latch the tailgate, then the tailgate can be secured, but the operation becomes difficult and aesthetically unpleasing

Engineering Contradiction:

Improvetailgate securingVSAvoidtailgate opening and closing

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the traditional chain and hook mechanical system with a rotary latch mechanism that uses rotational motion to engage and disengage the tailgate. This substitution maintains the securing function while dramatically improving ease of operation, allowing the tailgate to be opened with a simple rotational motion rather than manual chain manipulation.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The rotary latch mechanism introduces dynamic movement through rotation, transforming the static chain-and-hook system into an actively operable mechanism. The rotary component allows for smooth engagement and disengagement through controlled rotational motion, making the tailgate operation more convenient while maintaining secure latching.

Inventive Principle:

Principle #15Dynamics

2Reliability

If a chain and hook system is used to latch the tailgate, then the tailgate can be secured, but the appearance becomes unpleasing

Engineering Contradiction:

Improvetailgate securingVSAvoidaesthetic appeal

Core Design Contradiction:

ReliabilityVSShape

Solution Approach 1:

The patent replaces the visually unpleasing chain and hook system with a compact rotary latch mechanism that has a much smaller profile and more modern appearance. This substitution maintains the necessary securing function while significantly improving the aesthetic appeal of the tailgate area by eliminating the bulky chain and hook components.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If a rotary latch mechanism is implemented, then ease of operation is improved, but device complexity increases

Engineering Contradiction:

Improvetailgate opening and closingVSAvoidlatch mechanism complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The rotary latch mechanism is divided into distinct functional segments: the rotary component for operation, the latch arm for engagement, and the striker for positioning. This segmentation allows each component to perform its specific function efficiently, simplifying the overall design while maintaining ease of operation. The modular nature of the segmented components also facilitates easier manufacturing and maintenance.

Inventive Principle:

Principle #1Segmentation
