Solution Overview

Problem

Current cleaning devices, particularly in commercial dishwashing technology, face challenges in flexible billing models that do not account for the intensity of use or careful handling, leading to unfair compensation for operators and providers.

Innovation Solution

A cleaning device with a controller that records usage variables, assigns weightings based on usage intensity, and accumulates usage times to generate usage information, allowing for more accurate and flexible billing models that reward careful handling and usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple fluid tanks or cleaning zones are used to increase throughput, then productivity is improved, but energy consumption increases significantly

Engineering Contradiction:
ImprovethroughputVSAvoidenergy consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic heating control where the controller activates heating elements based on real-time detection of water temperature and cleaning program requirements. This dynamic adjustment ensures heating occurs only when and where needed, rather than continuously heating multiple tanks, thereby maintaining productivity while reducing energy consumption.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies heating elements locally at specific positions within the cleaning device where water temperature needs to be maintained. Rather than heating entire tanks uniformly, the system provides localized heating only in regions where thermal energy is required for cleaning operations, optimizing energy efficiency while preserving throughput capability.

Inventive Principle:
Principle #3Local quality

2Ease of operation

If billing is based purely on rental period, then ease of operation is improved, but fairness and accuracy of compensation deteriorates

Engineering Contradiction:
Improvebilling simplicityVSAvoidusage measurement accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent incorporates a feedback mechanism where the controller continuously monitors usage variables (number of cleaning cycles, duration, intensity) and uses this information to dynamically adjust billing calculations. This feedback loop enables accurate usage-based billing that reflects actual device utilization, providing fair compensation while maintaining operational simplicity through automated calculations.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system automatically records usage data and performs billing calculations without requiring manual intervention. The controller self-monitors operational parameters and generates usage information, enabling the billing system to serve itself by automatically computing accurate charges based on detected usage patterns, thus maintaining ease of operation while achieving measurement precision.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If usage variables and weightings are recorded and accumulated, then measurement precision is improved, but device complexity increases

Engineering Contradiction:
Improveusage information accuracyVSAvoidcontroller complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The controller is designed to perform multiple functions: it manages cleaning operations, monitors usage variables, accumulates usage data, calculates billing information, and controls heating elements. By making the controller universal and multi-functional, the patent avoids adding separate dedicated devices for each function, thereby improving measurement precision without proportionally increasing overall device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)
