Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual preparation and application of chemical agents is used, then water quality maintenance can be achieved, but the operation complexity increases and cleaning period extends

Engineering Contradiction:
Improvewater quality maintenance operationVSAvoidcleaning period
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The pool robot performs water quality maintenance autonomously by detecting water quality parameters, navigating to target regions, and automatically dispersing reagents without human intervention. The robot serves itself by integrating sensing, decision-making, and actuation functions into a single autonomous system, eliminating the need for manual preparation and application of chemical agents.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical operations with an automated robotic system that uses electronic control, sensors, and automated dispensing mechanisms. The robot substitutes human operators by integrating water quality sensors, navigation systems, and automated reagent delivery mechanisms into a unified autonomous platform.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If manual preparation and application of chemical agents is used, then water quality maintenance can be achieved, but maintenance costs increase

Engineering Contradiction:
Improvewater quality maintenance operationVSAvoidmaintenance system
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The pool robot integrates multiple functions into a single device: water quality detection, navigation, reagent storage, and automated dispensing. This multi-functional design consolidates what would otherwise require separate manual operations and equipment, reducing overall system complexity while improving ease of operation.

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

Solution Approach 2:

The patent combines detection modules, navigation systems, reagent storage tanks, and dispensing mechanisms into a single integrated robotic platform. By merging these previously separate functions into one autonomous system, the patent reduces the complexity of coordinating multiple manual operations while maintaining comprehensive water quality maintenance capabilities.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If chemical agents are spread manually onto water surface, then disinfection and clarification can be achieved, but reagent distribution uniformity decreases

Engineering Contradiction:
Improvereagent distributionVSAvoidreagent application
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces manual reagent application with an automated robotic system that uses electronic control for precise navigation and dispensing. The robot substitutes human operators by integrating water quality sensors, navigation systems, and automated reagent delivery mechanisms into a unified autonomous platform, ensuring consistent and uniform distribution.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The pool robot uses water quality sensors to detect parameters in real-time, processes this information to determine target regions requiring treatment, and adjusts reagent dispensing accordingly. This closed-loop feedback system ensures that reagents are distributed uniformly and only where needed, improving reliability while maintaining automated operation.

Inventive Principle:
Principle #23Feedback
