Solution Overview
Problem
Existing work devices, particularly cleaning devices for commercial applications, face challenges in ensuring operational safety and reliability due to the need for immediate reactions to obstacles or critical situations, often requiring user intervention for emergency stops.
Innovation Solution
A method for operating a work device that includes detecting safety-relevant situations using sensors, initiating a braking process, processing driving parameters, and selectively choosing between continuing the braking process or triggering an emergency braking process based on these parameters to prevent damage, thereby enhancing autonomy and minimizing user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If immediate emergency braking is triggered when an obstacle is detected, then operational safety is improved, but unnecessary emergency stops increase and operating range is reduced
Solution Approach 1:
The system performs preliminary evaluation of driving parameters (speed, distance to obstacle, braking capability) before triggering emergency braking. This preliminary assessment allows the device to determine whether standard braking suffices or if emergency braking is truly necessary, reducing unnecessary emergency stops while maintaining safety
Solution Approach 2:
The system dynamically adjusts braking response based on processed driving parameters. By evaluating current speed, distance to obstacle, and braking capability, the system adapts the braking intensity appropriately - using gentler braking when parameters allow and reserving emergency braking for critical situations where parameters indicate imminent danger
2Reliability
If emergency braking is triggered for all detected obstacles, then safety is improved, but user intervention is required frequently
Solution Approach 1:
The control device autonomously evaluates driving parameters and determines the appropriate braking response without requiring user intervention. The system independently assesses whether standard braking or emergency braking is needed based on processed parameters, making the safety response self-managing and reducing the burden on users
Solution Approach 2:
The system continuously monitors driving parameters and uses this feedback to adjust braking responses. By processing real-time data about speed, distance, and braking capability, the system provides appropriate safety responses that match actual conditions, avoiding unnecessary emergency stops that would require user intervention
3Productivity
If the work device operates closer to edges and obstacles, then operating range is expanded, but risk of damage increases
Solution Approach 1:
The system dynamically adjusts safety margins and braking responses based on real-time driving parameters. When operating close to edges or obstacles, the system evaluates current speed and distance parameters to determine appropriate braking intensity, allowing closer operation when parameters permit while maintaining safety when parameters indicate risk
