Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-theft systems for battery-operated electric machine tools are not easily retrofittable and do not provide reliable protection against theft, often requiring a remote control for enabling/disabling the device and lacking comprehensive tracking and positioning capabilities.
Innovation Solution
An anti-theft module that can be installed as an adapter between a rechargeable battery interface and a replaceable battery, featuring a position determination unit and data interfaces for wireless or wired communication, allowing for real-time location tracking and enabling/disabling of the tool, with a focus on modularity, reusability, and easy retrofitting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote control system is used to enable/disable the tool, then the tool can be controlled remotely, but the user must always have the remote control on hand which reduces convenience
Solution Approach 1:
The enabling/disabling functionality is extracted from the tool itself and integrated into the battery unit. The battery now contains the electronic component that can independently activate or deactivate the tool's motor, eliminating the need for a separate remote control device and simplifying the user interaction to simply attaching or detaching the battery.
Solution Approach 2:
The battery unit performs the enabling/disabling function autonomously through its electronic component without requiring external control. When the battery is attached to the tool, the electronic component automatically enables the motor; when detached, it automatically disables the motor, making the system self-regulating.
2Reliability
If existing anti-theft systems are installed on battery-operated tools, then theft protection is provided, but the systems are not easily retrofittable and require significant modification
Solution Approach 1:
The battery unit is designed as a universal platform that can be used across different tool models while integrating anti-theft functionality. The electronic component in the battery provides theft protection through geofencing and tracking features that work with any tool in the system, eliminating the need for model-specific anti-theft installations and enabling easy retrofitting of existing tools.
Solution Approach 2:
The battery's electronic component acts as an intermediary between the tool and the central server. It contains the necessary communication interfaces and processing capabilities to implement theft protection, location tracking, and geofencing functions independently within the battery, avoiding the need to modify the tool's existing structure or electronics.
3Measurement precision
If position determination is implemented in the tool itself, then location tracking is available, but it increases device complexity and power consumption
Solution Approach 1:
The position determination functionality is extracted from the tool and relocated to the battery unit. The battery's electronic component now houses the position determination means and communicates location data to the central server, eliminating the need for separate positioning hardware in the tool and reducing overall system complexity.
Solution Approach 2:
The battery unit independently performs position determination and communicates location information to the central server without requiring additional processing power or communication interfaces in the tool. The battery's electronic component self-manages the positioning function, reducing the computational burden on the tool's motor control system.
4Reliability
If comprehensive anti-theft features are added to protect against theft, then security is improved, but the device complexity and cost increase
Solution Approach 1:
Multiple anti-theft functions including position determination, geofencing, tracking, and enabling/disabling capabilities are merged into a single electronic component within the battery unit. This integration consolidates what would otherwise be separate systems into one unified module, reducing overall complexity while maintaining comprehensive theft protection.
Solution Approach 2:
The battery's electronic component is designed as a multi-functional unit that provides theft protection, location tracking, geofencing, and motor control capabilities simultaneously. This universal component works across different tool models and provides comprehensive security features without requiring separate dedicated systems for each function.
