Removable Door Armrest Mounting via Striker Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Off-road vehicles like Jeeps and Humvees face challenges when doors are removed, as there is no secure and comfortable solution for the operator to rest their arms during operation, compromising safety and comfort.
Innovation Solution
The Armrest for Removable Door Vehicles employs a mounting system that utilizes the door striker plate and crossbar to provide a stable and adjustable armrest, allowing for secure engagement and easy installation/removal, featuring a mount with an 'L' shape, angled portion, ledge, notch, or enclosed notch configurations for secure attachment and height adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If doors are removed from the vehicle for off-road operation, then vehicle maneuverability and off-road capability are improved, but operator safety and comfort deteriorate due to lack of armrest support
Solution Approach 1:
The invention extracts the armrest function from the door assembly, allowing the door to be removed for off-road operation while the armrest remains mounted on the vehicle body through the door striker plate interface, thus maintaining operator safety and comfort independently of door presence
Solution Approach 2:
The door striker plate is designed to serve multiple functions: its original door latching function and a new function as a mounting interface for the armrest, allowing the same structural element to provide support whether doors are attached or removed
2Strength
If a fixed armrest mounting structure is used, then structural strength and stability are improved, but ease of installation and removal deteriorates
Solution Approach 1:
The armrest mounting system is divided into separate components (armrest assembly and door striker plate interface) that can be independently installed and removed, allowing strong mechanical attachment during use while enabling easy removal when needed
Solution Approach 2:
The mounting system transitions from a static permanent installation to a dynamic configurable state, allowing the armrest to be securely attached during operation and easily removed for maintenance or door reinstallation through the adjustable clamp mechanism
3Adaptability or versatility
If the armrest mounting system is made complex to provide adjustment options, then adaptability to different operators is improved, but device complexity increases
Solution Approach 1:
The system provides essential adjustment capabilities through simple mechanisms (positionable clamp, adjustable height slots) that cover the range needed for most operators without implementing overly complex adjustment systems, achieving sufficient adaptability with minimal added complexity

AI summary
An armrest for removable door vehicles is disclosed which allows for the user of a vehicle having removable doors to use the door frame and existing striker plate to work with the removed door(s) for insertion of the mount disclosed into the door striker plate so that the mount may support an armrest attached to the upper leg of the mount via a housing.
