Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple sump pumps and controllers are used, then system reliability is improved, but device complexity increases

Engineering Contradiction:
Improvesystem reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system is divided into multiple independent controller-pump units, each capable of autonomous operation. Each controller monitors water level signals and controls a specific pump, creating modular segments that can function independently. This segmentation improves reliability through redundancy while managing complexity by standardizing each module's design.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system changes the parameter of controller quantity from one to multiple, and pump quantity from one to multiple. By increasing these parameters, the system achieves improved reliability through redundancy. The patent specifically implements two or more controllers and two or more pumps, where each controller can independently activate pumps based on water level conditions.

Inventive Principle:
Principle #35Parameter changes

2Loss of information

If redundant sensors and controllers are implemented, then monitoring capabilities are improved, but system complexity increases

Engineering Contradiction:
Improvemonitoring capabilitiesVSAvoidsystem complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

Each controller receives feedback from water level sensors and adjusts pump operation accordingly. The system implements continuous monitoring where sensors detect water levels and provide signals to controllers, which then activate pumps when thresholds are exceeded. This feedback loop ensures comprehensive monitoring capabilities while maintaining systematic control.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

Each controller is designed to perform multiple functions: monitoring water levels, determining pump activation, controlling pump operation, and providing status feedback. This multi-functionality reduces the need for separate dedicated components for each function, thereby improving monitoring capabilities without proportionally increasing system complexity.

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

3Productivity

If multiple controllers operate pumps independently, then water removal efficiency is improved, but control complexity increases

Engineering Contradiction:
Improvewater removal efficiencyVSAvoidcontrol complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

Controllers are pre-programmed with activation thresholds and control logic before system operation. When water level sensors detect predetermined levels, controllers automatically activate appropriate pumps without requiring complex real-time decision-making. This preliminary configuration simplifies control complexity while maintaining high water removal efficiency.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Each controller independently monitors its assigned sensors and autonomously controls pump activation based on detected water levels. The controllers self-manage their operational parameters and activation timing without requiring centralized coordination, thereby improving water removal efficiency through parallel operation while reducing control complexity through decentralized autonomy.

Inventive Principle:
Principle #25Self-service
