Solution Overview

Problem

The automated lowering and raising of modern pickup truck tailgates can lead to interference and damage when the lower step portion collides with components attached to the hitch receiver, such as hitch balls or trailers, due to the lack of effective detection and mitigation systems.

Innovation Solution

A system that integrates detection sensors, such as RFID, ultrasonic, or optical sensors, with the vehicle's control system to detect potential interference conditions and prevent the tailgate from lowering into the hitch receiver, using existing truck components and a hitch cover plug insert to mitigate collisions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If automated lowering mechanism is implemented, then ease of operation is improved, but reliability deteriorates due to collision risk with hitch components

Engineering Contradiction:
Improveautomated tailgate loweringVSAvoidcollision prevention
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary detection of hitch components before the tailgate lowering operation commences. Sensors detect the presence of hitch balls, trailers, or other components in the potential path of the tailgate, and the system prevents activation of the automated lowering mechanism when obstructions are detected, thereby avoiding collisions before they occur.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors the environment around the tailgate using sensors that detect hitch components. This feedback information is processed by the control system to determine whether the automated lowering operation should proceed or be prevented, creating a closed-loop control system that adapts to real-time conditions.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If step-up design is added to tailgate, then ease of operation is improved for user access, but device complexity increases

Engineering Contradiction:
Improveuser access to bedVSAvoidtailgate structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The tailgate is divided into multiple segments: the main tailgate panel and one or more step-up portions that can be independently positioned. The step-up portions can be raised or lowered separately from the main tailgate, allowing users to access the bed more easily while maintaining the structural integrity and control of the overall tailgate system.

Inventive Principle:
Principle #1Segmentation

3Reliability

If detection sensors are integrated, then reliability is improved by preventing collisions, but device complexity increases

Engineering Contradiction:
Improvecollision detectionVSAvoidsensor integration
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sensor system is designed to detect multiple types of hitch components including hitch balls, trailers, and other equipment using the same basic sensor technology. The control system processes various sensor inputs and applies universal prevention logic regardless of the specific component type detected, reducing the need for specialized detection mechanisms for each component type.

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