Solution Overview

Problem

Existing cleaning robots lack flexibility and effectiveness in adapting to increased soiling events, such as parties or weather conditions, which can lead to suboptimal cleaning results.

Innovation Solution

A system and method that utilize control and communication means to detect events with increased soiling occurrences, allowing the cleaning robot to intensify its cleaning operations by adjusting the frequency, intensity, or area of cleaning based on detected events, such as calendar entries or weather information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the cleaning robot operates on a fixed schedule regardless of soiling events, then the device complexity is low, but the adaptability to increased soiling events deteriorates

Engineering Contradiction:
Improveadaptability to increased soiling eventsVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system detects events with increased soiling occurrence (such as parties or weather conditions) in advance and triggers additional cleaning operations before the actual cleaning is needed. The control means are configured to set the intensity of cleaning operations based on detected events, allowing the robot to proactively respond to soiling conditions rather than reacting after the fact.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If the cleaning robot intensifies cleaning operations in response to detected events, then the cleaning effectiveness improves, but the energy consumption increases

Engineering Contradiction:
Improvecleaning effectivenessVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The cleaning robot dynamically adjusts its operating parameters based on detected events. The control means set the intensity of cleaning operations (such as suction power, brush rotation speed, or cleaning area) depending on the type and severity of the detected event. This allows the system to optimize energy consumption by applying higher intensity only when and where needed, rather than operating at maximum capacity continuously.

Inventive Principle:
Principle #15Dynamics

3Reliability

If the cleaning robot performs frequent cleaning operations, then the cleanliness level improves, but the productivity decreases due to overutilization

Engineering Contradiction:
Improvecleanliness levelVSAvoidproductivity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system uses communication means to detect events with increased soiling occurrence and provides feedback to the control means, which then adjusts the cleaning schedule and intensity accordingly. This feedback mechanism ensures that cleaning operations are performed with appropriate frequency based on actual soiling conditions, preventing both overcleaning (which would reduce productivity) and undercleaning (which would compromise cleanliness levels).

Inventive Principle:
Principle #23Feedback
