Power Machine Control via Wireless Operator Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power machines lack efficient and secure methods for enabling or disabling functionality during startup procedures, particularly in ensuring authorized access and operation based on operator profiles.
Innovation Solution
A control system that utilizes a wireless connection between a mobile device and a power machine to provide access to certain functionalities, allowing operators to execute operations under a limited functionality mode until a connection is established with an approved operator's mobile device, which is associated with an operation profile, enabling full functionality upon verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the power machine allows full functionality operation during startup, then the ease of operation is improved, but the security against unauthorized access deteriorates
Solution Approach 1:
The control system performs preliminary authentication actions during startup by checking for the presence of authorized mobile devices and verifying operation profiles before enabling full machine functionality. This preliminary verification ensures security is established before operational access is granted.
Solution Approach 2:
The system dynamically adjusts the level of machine functionality available during startup based on authentication status. Initially, only limited functions are accessible, and upon successful verification of authorized operators via mobile devices, the system transitions to providing full operational access, making the security state dynamic rather than static.
2Reliability
If the power machine requires wireless connection verification for full functionality, then the security is improved, but the startup time increases
Solution Approach 1:
The control system performs wireless connection verification and operation profile checks as preliminary actions during the startup sequence. By integrating these security checks into the initial startup process rather than as a separate post-startup step, the system ensures authentication occurs before full functionality is enabled, maintaining security without adding significant time loss.
Solution Approach 2:
The system allows operators to skip certain authentication steps or use previously cached verification data when conditions permit, enabling faster startup while maintaining adequate security. This may include bypassing repeated verification for already-authenticated operators or using stored operation profiles to expedite the connection process.

AI summary
A control system of a power machine can be configured to allow certain power machine functionality based on a wireless connection with a mobile device. For example, a power machine can operate in a startup mode providing limited functionality to an operator (e.g., engine power, but no workgroup actuators). Access to additional power machine functionality (e.g., full functionality) can then be permitted based on establishing a wireless connection to a mobile device that corresponds to an operator profile for the power machine.
