Adjustable Interface Mount for Work Vehicle Operators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fixed interface positions in work vehicles, such as those found in tractors, can be uncomfortable or difficult for operators of varying sizes, particularly short or tall individuals, as they are typically designed for average-sized operators.
Innovation Solution
An adjustable interface mount system comprising a first and second mounting arm with a bend and an adjustable slotted interface, allowing the arms to slide between expanded and contracted positions, enabling the interface unit to be positioned optimally for operators of different heights, accommodating a wider range of sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed interface position is used, then the device complexity is reduced, but the adaptability to operators of varying sizes deteriorates
Solution Approach 1:
The mounting arm is designed with telescopic sections that can slide relative to each other through a slotted interface, transforming the fixed structure into a dynamic, adjustable one. This allows the interface mount to adapt to different operator heights while maintaining a relatively simple overall structure.
Solution Approach 2:
The mounting arm is divided into multiple sections (first mounting arm and second mounting arm) that can move independently relative to each other. This segmentation enables adjustable length while keeping each individual component simple in design.
2Adaptability or versatility
If an adjustable interface position is implemented, then the adaptability to operators of varying sizes is improved, but the device complexity increases
Solution Approach 1:
The mounting arm incorporates telescopic capability through slotted interfaces that allow controlled movement between expanded and contracted positions, providing adjustability without requiring complex mechanical systems.
Solution Approach 2:
The mounting arm includes a bend that allows adjustment in multiple directions, adding dimensional flexibility to the interface position without significantly increasing structural complexity.
3Ease of operation
If the mounting arm is made telescopic, then the ease of operation is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The telescopic mounting arm uses a slotted interface design with mating portions that have substantially similar contours, allowing straightforward manufacturing while enabling smooth relative movement between arm sections.
Solution Approach 2:
The slotted interface allows for adjustable positioning parameters along the length of the mounting arm, enabling operators to customize the interface position to their needs while using standard manufacturing tolerances through the contoured mating portions.

AI summary
In one embodiment, an interface mount for a work vehicle includes a first mounting arm and a second mounting arm. The first mounting arm includes a mounting portion disposed at a first end of the first mounting arm and configured to mount to a base bracket, and a first mating portion disposed at a second end of the first mounting arm, wherein the first mounting arm includes a bend disposed between the first end and the second end. The second mounting arm includes a second mating portion disposed at a first end of the second mounting arm, wherein the first mating portion and the second mating portion have substantially similar contours, and the first mating portion is configured to be coupled to the second mating portion via an adjustable slotted interface, and an interface mounting portion disposed at a second end of the second mounting arm and configured to receive an interface unit. The adjustable slotted interface is configured to selectively enable the first mounting arm and the second mounting arm to slide relative to one another between an expanded position and a contracted position.
