Power Machine Startup Mode for Limited Access

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Power machines experience delays during startup due to the requirement of entering a passcode, which restricts operators from accessing functionality until the display is fully initialized, leading to frustration and delayed work-site operations.

Innovation Solution

Implementing a startup mode that allows limited access to power machine functionality before full initialization, enabling operators to perform certain operations during the startup process, with permissions that can include operating the power source but restrict hydraulic operations, and requiring proof of authorization after initialization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a passcode requirement is implemented to secure power machine functionality, then security and authorized operation are improved, but startup time and operator productivity deteriorate

Engineering Contradiction:

ImprovesecurityVSAvoidstartup time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary initialization of the display and input device before requiring passcode entry. The machine enters a startup mode where limited functionality is available during the initialization process, so that when the passcode prompt appears, the operator can immediately enter it without waiting for additional system preparation, thereby reducing overall startup time while maintaining security

Inventive Principle:

Principle #10Preliminary action

2Stability of the object's composition

If the display is fully initialized before allowing operator input, then system stability and security are improved, but operator frustration and work-site operation delays worsen

Engineering Contradiction:

Improvesystem stabilityVSAvoidoperator frustration

Core Design Contradiction:

Stability of the object's compositionVSEase of operation

Solution Approach 1:

The system segments functionality into different levels: a startup mode with limited functionality available during initialization, and a full operation mode requiring passcode authentication. This segmentation allows the display to be partially usable during initialization (reducing operator frustration) while maintaining system stability through controlled access to critical functions

Inventive Principle:

Principle #1Segmentation

3Productivity

If limited functionality is provided during startup mode, then operator productivity is improved, but system security and control worsen

Engineering Contradiction:

Improveoperator productivityVSAvoidsystem security

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system dynamically adjusts functionality based on operational context. During startup mode, limited functionality is permitted to maintain productivity. Upon detecting passcode entry or timeout conditions, the system dynamically transitions to full operation mode or default mode, thereby maintaining security control while allowing productivity during the transition period

Inventive Principle:

Principle #15Dynamics

AI summary

A power machine (200) can be configured to operate in one or more startup modes during startup processes (300), including during startup processes (310) for displays (286) or other input devices. Access to power machine functionality, including access only to limited power machine functionality, can be enabled during the startup processes (300) according to permissions (332) of the startup mode.
