Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing electrical connections for removable tailgates on vehicles, such as pigtail connections, experience mechanical wear and corrosion due to repeated opening and closing, leading to degraded power supply to sensors and other electrical features.
Innovation Solution
An electrical connecting assembly featuring a hyperboloid pin and socket with dielectric oil, which provides corrosion resistance and facilitates a robust electrical connection between the vehicle body and tailgate, using a bushing and pin connector system that coats the hyperboloid pin with dielectric oil for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a pigtail connection is used for electrical connection in a removable tailgate, then the connection can be easily installed, but it experiences mechanical wear and corrosion due to repeated opening and closing
Solution Approach 1:
The patent introduces a dielectric oil as an intermediary substance that coats the hyperboloid pin, creating a protective barrier between the electrical connector and the corrosive environment. This mediator prevents direct contact between the metal surfaces and moisture/contaminants, thereby reducing corrosion and mechanical wear while maintaining the ease of installation provided by the hyperboloid design
Solution Approach 2:
The patent replaces the traditional pigtail mechanical connection with a hyperboloid pin and socket system that incorporates dielectric oil coating. This substitution transforms the purely mechanical connection into a hybrid system that combines mechanical engagement with chemical protection (dielectric oil coating), thereby improving reliability against wear and corrosion while maintaining ease of installation
2Ease of operation
If the tailgate is designed to be readily removable, then ease of operation is improved, but supplying power to sensors becomes more difficult
Solution Approach 1:
The patent employs a dynamic electrical connection system using a hyperboloid pin and socket that can accommodate the repeated insertion and removal of the tailgate. The split line design allows the connector to flex and adapt to mechanical movements, maintaining reliable electrical contact throughout the operational cycle while preserving tailgate removability
Solution Approach 2:
The dielectric oil acts as a mediator that protects the electrical connection components from environmental degradation during repeated attachment and detachment operations. This protective coating ensures that the electrical connection remains reliable over time, addressing the power supply difficulty without compromising the ease of operation provided by removable tailgate design

AI summary
Systems and apparatus are disclosed for an electrical connector for a removable tailgate. An example connector for a vehicle tailgate includes a body, a hyperboloid socket and dielectric oil. The example body defines a chamber and a split line extending from the chamber. The split line facilitates penetration of a hyperboloid pin into the chamber. The example hyperboloid socket is disposed in the chamber and aligned with the split line. The example dielectric oil partially fills the chamber to coat the hyperboloid pin to provide corrosion resistance for the hyperboloid pin.
