Tie-Down Handle With Integrated Electric Outlet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles lack a secure and convenient method to access and utilize their electrical systems externally, particularly for powering devices and maintaining oil temperatures in extreme cold conditions, without obstructing the hood or requiring complex installations.
Innovation Solution
A tie-down handle assembly with an integrated electric outlet and control module that allows secure attachment to the vehicle structure, providing external power access while allowing for selective operation of vehicle systems like battery charging and block heating, with indicators for charge state and a movable cover for protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an electric outlet is provided externally on the vehicle, then power access for external devices and systems is improved, but the vehicle structure becomes more complex
Solution Approach 1:
The patent combines the electric outlet with the existing tie-down handle assembly, merging two separate functions (cargo securement and power access) into a single integrated component. This eliminates the need for separate external electrical connections while providing convenient power access at the vehicle exterior.
Solution Approach 2:
The tie-down handle assembly is transformed into a multi-functional component that serves both its original purpose of securing cargo and a new function of providing external power access. The electric outlet is integrated into the handle assembly, allowing the same structure to fulfill multiple roles.
2Ease of operation
If the electric outlet is accessible externally, then convenience for powering devices is improved, but protection of the electric system is worsened
Solution Approach 1:
The cover for the electric outlet is designed to be movable between an open position (allowing access) and a closed position (providing protection). This dynamic element allows the system to adapt between convenience and protection based on operational needs, maintaining reliability while enabling ease of use.
Solution Approach 2:
A cover is introduced as an intermediary element between the external environment and the electric outlet. This intermediate component provides physical protection and environmental sealing while still allowing controlled access when needed, resolving the conflict between convenience and protection.
3Adaptability or versatility
If the tie-down handle assembly is modified to include an electric outlet, then functionality is improved, but manufacturing complexity is worsened
Solution Approach 1:
The electric outlet components are integrated into the existing tie-down handle assembly structure during manufacturing. By combining these components into a single integrated unit, the patent reduces the number of separate parts that need to be assembled and minimizes manufacturing steps, offsetting the increased functionality with streamlined production.

AI summary
A disclosed tie-down handle assembly for a vehicle includes a mount portion attachable to a vehicle structure and an electric outlet for coupling to an electric system of the vehicle. A disclosed method of operating a vehicle electric interface system includes, identifying an electrical parameter from an external electrical conduit coupled to an electric outlet within a tie-down handle assembly attached to a vehicle structure, selecting an output from a vehicle electric system in response to the measured electric parameter at the electric outlet and operating the vehicle electric system to either generate a power output to the electric outlet or direct power input into the electric outlet to a vehicle electric system in response to the selected output.
