Solution Overview

Problem

Self-propelled floor care devices and their base stations are vulnerable to theft due to their high resale value and exclusivity, with limited effective measures for theft prevention in public areas.

Innovation Solution

A base station with a blocking function that activates a device lock when the connection to the power grid is disrupted, combined with authentication options and alarm systems to deter theft, and a locking interface for securing the floor care device, reducing the attractiveness and ease of resale of stolen units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the base station is made portable and valuable with high resale value, then its utility and exclusivity are improved, but it becomes more vulnerable to theft

Engineering Contradiction:
Improveutility and exclusivityVSAvoidtheft vulnerability
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary anti-action by implementing a locking function that proactively prevents theft before it occurs. The control system continuously monitors the plug connection status and automatically activates the device lock when disconnection is detected, creating a preventive barrier against theft rather than reacting after the fact. This anticipatory measure directly addresses the theft vulnerability while preserving the base station's portability and value.

Inventive Principle:
Principle #9Preliminary anti-action

2Object-affected harmful factors

If a locking function is implemented to prevent theft, then security against theft is improved, but the device complexity increases

Engineering Contradiction:
Improvetheft protectionVSAvoidcontrol system complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The locking function operates autonomously using the existing control system of the base station. The control system self-monitors the plug connection status through voltage detection and automatically activates the device lock without requiring external intervention or additional complex control mechanisms. This self-service approach provides effective theft protection while minimizing increases in device complexity by leveraging existing system capabilities.

Inventive Principle:
Principle #25Self-service

3Object-affected harmful factors

If the base station is permanently installed in a fixed location, then theft risk is reduced, but mobility and flexibility are lost

Engineering Contradiction:
Improvetheft riskVSAvoidmobility and flexibility
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The patent implements a dynamic security system that adapts to the base station's operational state. The device lock is activated only when the plug is disconnected, allowing the base station to remain mobile and flexible during normal operation when connected. When unplugged, the system dynamically transitions to a locked state, providing theft protection without permanently restricting mobility. This dynamic approach resolves the contradiction between fixed installation and mobility.

Inventive Principle:
Principle #15Dynamics
