Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The theft of battery-powered power tools has increased, posing a significant challenge for retailers due to their compact size and ease of use, which has detrimental effects on retail sales.

Innovation Solution

A system and method are implemented to prevent operation of battery-powered power tools until legitimate purchase is verified, using an out-of-band technique to initiate hardware registration and enablement, involving wake-up sensors, locking and unlocking devices, and communication interfaces to manage activation states.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If battery-powered power tools are made compact and easy to use, then ease of operation is improved, but theft risk increases

Engineering Contradiction:

Improveease of useVSAvoidtheft risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary actions by implementing activation state control and purchase verification mechanisms before the tool can be operated. The tool remains in a locked/activated state until legitimate purchase is verified, preventing theft while maintaining compact design for ease of operation.

Inventive Principle:

Principle #10Preliminary action

2Object-affected harmful factors

If activation control systems are implemented to prevent theft, then loss prevention is improved, but device complexity increases

Engineering Contradiction:

Improveloss preventionVSAvoidsystem complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The system introduces an intermediary activation control mechanism that mediates between the tool and the user. The activation state code acts as an intermediary layer that verifies purchase legitimacy before allowing operation, providing loss prevention while managing complexity through a structured control framework.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Object-affected harmful factors

If tools remain locked until purchase verification, then theft prevention is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvetheft preventionVSAvoidoperational accessibility

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The system applies preliminary anti-action by implementing a locked state that prevents unauthorized operation. The tool remains inactivated until purchase verification occurs, creating a counter-action to potential theft while allowing legitimate users to operate the tool after verification.

Inventive Principle:

Principle #9Preliminary anti-action

AI summary

An electronic power tool device includes an electronic processor, a communication interface in communication with the electronic processor, and a wake-up sensor configured to generate a wake signal for activating the communication interface and the electronic processor responsive to a stimulus. The communication interface is configured to receive a first electronic message that includes an activation state and transmit the first received electronic message to the electronic processor. The electronic processor is configured to control the activation state of the electronic power tool device to allow or prevent operation of the electronic power tool device based on the first received electronic message.
