Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Backhoe loader control pods are not fully adjustable, making it difficult to provide consistently comfortable and ergonomic operating positions for operators of varying sizes and shapes, affecting productivity and safety.
Innovation Solution
A position-adjustable, dual-pod control system with a horizontal cross beam, pivotally coupled brackets, bearings, and pod arms that allow for multi-directional movement, enabling operators to adjust the control pods' position in both parallel and perpendicular directions to the fore-aft centerline.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If control pods are fixed in position, then device complexity is reduced, but adaptability to operators of varying sizes and shapes deteriorates
Solution Approach 1:
The control pod system transitions from a fixed configuration to a dynamic, multi-directionally adjustable configuration. The pod arms are designed to pivot about multiple axes (first axis perpendicular to the fore-aft centerline, and second axis parallel to the fore-aft centerline), allowing the control pods to be repositioned in multiple directions to accommodate operators of various sizes and shapes.
Solution Approach 2:
The adjustment mechanism adds another dimension of freedom by enabling pivoting about two different axes. The first axis allows pivoting perpendicular to the fore-aft centerline, while the second axis enables pivoting parallel to the fore-aft centerline, creating a two-dimensional adjustment capability that significantly increases adaptability.
2Ease of operation
If control pods are made multi-directionally adjustable, then operator comfort and ergonomics are improved, but device complexity increases
Solution Approach 1:
The system employs dynamic adjustment mechanisms with pivot points and bearings that allow the control pods to be repositioned. The pod arms can pivot about the first axis (perpendicular to fore-aft centerline) and the second axis (parallel to fore-aft centerline), providing operators with the ability to customize their control positions for optimal comfort and ergonomics.
Solution Approach 2:
The control pod system is segmented into movable components (pod arms, brackets, bearings) that can be independently adjusted. This segmentation allows each control pod to be positioned separately, enabling fine-tuned ergonomic adjustments for each hand's control position.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The adjustable control system enhances operator comfort and ergonomics, improving productivity and safety by allowing for customizable operating positions, accommodating operators of different sizes and shapes, and reducing the need for frequent seat and control pod adjustments.
Implementation Method 1
The pair of bearings may be coaxially aligned along a second axis that is at least substantially perpendicular to the fore-aft centerline thereby enabling cross beam, brackets and pod arms to pivot about the second axis and at least substantially parallel to the fore-aft centerline

AI summary
A position-adjustable, dual-pod control system for a machine, such as a backhoe loader is disclosed. The system includes a horizontal cross beam connected to a pair of brackets. The pair of brackets are mounted to the machine by way of a pair of bearings that enables pivotal movement of the cross beam in the fore and aft directions while the cross beam is positioned perpendicularly to the fore and aft direction or the fore-aft centerline of the machine. The bottom end of each pod arm is pivotally coupled to the brackets thereby enabling the pod arms to be pivoted towards or away from the centerline. Each bracket includes a through hole that accommodates a bearing that is mounted to the machine, such as to the floor of the machine.
