Power Tool Authentication via Asset Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Power tools, battery packs, and chargers often get lost, misplaced, or stolen, leading to significant losses for workshops and construction companies. Existing methods for theft prevention, such as physical locking, are inadequate, especially in dynamic construction site environments.
Innovation Solution
A method that restricts the use of power tool devices by assigning them to specific areas and/or wireless networks through an asset management system. The method involves determining the location and network connectivity of the tool devices and disabling or limiting their operation if they are not within the assigned area or network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical locking devices are used to protect power tools, then theft prevention is improved, but ease of operation deteriorates due to difficulty in ensuring proper locking on construction sites
Solution Approach 1:
The patent replaces mechanical locking systems with an electronic/software-based authentication system. The power tool includes an authentication unit that performs software-based verification, eliminating the need for physical locks and keys. This substitution maintains security (reliability) while dramatically improving ease of operation, as users simply need to authenticate digitally rather than physically lock/unlock mechanisms.
Solution Approach 2:
The authentication system enables the power tool to automatically verify user credentials and control its own operation state. The tool itself performs the authentication check and decides whether to enable or disable functionality, eliminating the need for external locking mechanisms or manual intervention. This self-service approach improves both reliability (automatic security enforcement) and ease of operation (no manual locking required).
2Reliability
If software-based authentication is implemented in power tools, then theft prevention is improved, but device complexity increases
Solution Approach 1:
The authentication unit serves multiple functions: it authenticates users, controls tool operation state (enabled/disabled), and integrates with the existing power tool system. By making the authentication unit multi-functional, the patent reduces the need for separate dedicated components, thereby limiting the increase in device complexity while maintaining improved theft prevention.
Solution Approach 2:
The patent merges the authentication functionality with the existing power tool control systems. The authentication unit is integrated into the tool's existing electronics and control architecture, combining security functions with operational control. This merging approach prevents the authentication system from becoming a separate complex subsystem, thereby limiting overall device complexity increase.

AI summary
A method to restrict the use of a tool device, the tool device being a battery pack, a power tool, or a charger of a power tool system, is proposed, the method is comprising the steps of: - assigning the tool device to a first area and/or to a first wireless network, particularly by an asset management system, - locating the tool device in a first area and/or registering the tool device to a first wireless network, - determining whether the tool device is in the first area and/or connected to and/or connectable to the first wireless network, - disabling or limiting the operation of the tool device if the result of the determining is that the tool device is not in the first area and/or not connected to and/or not connectable to the first wireless network.
