Solution Overview

Problem

Existing power machines lack an efficient and flexible mechanism for securely and reliably coupling various implements, which limits their versatility and ease of use in performing different tasks without requiring extensive reconfiguration or tool use.

Innovation Solution

The implementation of an implement carrier system on power machines, featuring a pivotally mounted coupler block with locking mechanisms and alignment features, allows for secure attachment and power transmission to implements, enabling easy switching between different tasks without the need for tools.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional implement coupling mechanisms are used, then the power machine can perform basic tasks, but the versatility and ease of switching between different implements is limited

Engineering Contradiction:
ImproveversatilityVSAvoidcomplexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The implement carrier is designed with a universal coupling mechanism that can accommodate multiple types of implements through standardized coupler interfaces. The coupler block with multiple couplers (hydraulic and electrical) provides a multi-functional connection system that works with various implement types without requiring dedicated coupling mechanisms for each implement, thereby achieving versatility without proportional increases in system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The coupling system is divided into separate functional modules: the implement carrier frame, the pivotally mounted coupler block, individual couplers (hydraulic and electrical), and the locking mechanism. This segmentation allows each component to be optimized independently and facilitates easy replacement or maintenance of specific elements without affecting the entire system, resolving the complexity issue while maintaining versatility.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If traditional implement attachment methods are used, then implements can be secured to the power machine, but the process requires extensive time and tool use

Engineering Contradiction:
Improveease of attachmentVSAvoidtime for task changes
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The locking mechanism is designed to be actuated by the operator's own body weight or simple manual input during the attachment process, eliminating the need for external tools or complex operating procedures. The self-latching feature automatically secures the implement once positioned, reducing both the time required and the complexity of the attachment operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The coupler block is pre-positioned and pivotally mounted on the implement carrier frame, with alignment features that guide the couplers into proper engagement positions before final locking occurs. This preliminary positioning action ensures that when the implement is attached, the couplers are already aligned for immediate connection, eliminating time-consuming manual alignment procedures.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If implements are frequently switched to perform different tasks, then operational flexibility improves, but the reconfiguration time increases

Engineering Contradiction:
Improveoperational efficiencyVSAvoidreconfiguration time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The coupler block is mounted to pivot relative to the implement carrier frame, providing dynamic adjustment capability during the attachment process. This pivotal movement allows the coupler block to automatically align with and engage the implement's couplers during the switching operation, enabling rapid implement changes without manual repositioning or extensive reconfiguration time, thereby improving productivity.

Inventive Principle:
Principle #15Dynamics
