Solution Overview

Problem

Standard operator interfaces for machines like skid steer loaders are not suited for controlling complex removable implements with additional hydraulic circuits, requiring operators to control implements outside the cab or using additional seats and inadequate control mechanisms.

Innovation Solution

An adjustable operator interface is provided, pivotally attached to a frame with a ratchet mechanism that allows the interface to be easily positioned within the operator compartment, featuring a control lever or joysticks for controlling hydraulic actuators, enabling ergonomic operation of complex implements like backhoes from within the cab.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the standard operator interface is used to control complex removable implements, then the machine's existing control system is utilized, but the interface is inadequate for handling implements with additional hydraulic circuits and complex functions

Engineering Contradiction:

Improveinterface adaptabilityVSAvoidcontrol capability

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The operator interface is made dynamically adjustable through pivotal attachment to the frame, allowing it to be repositioned to different locations within the operator compartment. This dynamic reconfigurability enables the interface to adapt to different implement configurations and operator preferences, resolving the contradiction between using the existing control system and achieving adequate control capability for complex implements.

Inventive Principle:

Principle #15Dynamics

2Ease of operation

If a separate operator interface for the removable implement is provided, then control of complex implements is enabled, but the operator must control the implement while outside the machine's cab requiring an additional seat

Engineering Contradiction:

Improvecontrol capabilityVSAvoidoperational setup

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The separate operator interface for the removable implement is merged with the machine's existing operator compartment by pivotal attachment to the frame. This combining allows the implement controls to be operated from within the protected cab environment rather than requiring an external position, eliminating the need for an additional seat and external operating position while maintaining full control capability.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If the implement uses the machine interface to control the implement, then the operator can control the implement within the confines of the cab, but the standard interface may not be suited for handling implements with more complex functions requiring additional control levers

Engineering Contradiction:

Improveoperating positionVSAvoidinterface functionality

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

Inventive Principle:

Principle #15Dynamics

4Ease of operation

If the operator interface is fixed to the frame, then the structure is simple and stable, but the interface cannot be adjusted to different positions for ergonomic operation

Engineering Contradiction:

ImproveergonomicsVSAvoidinterface structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The operator interface is pivotally attached to the frame about an axis, enabling it to be adjusted to different positions and orientations. This dynamic attachment mechanism provides ergonomic flexibility while maintaining structural simplicity through the use of a straightforward pivotal connection rather than complex adjustment mechanisms.

Inventive Principle:

Principle #15Dynamics
